Here it is!

Samurais, SJ410's, sidekicks, whatever you've got, it belongs here if it's a Suzuki.

I tried to pull most of the topics regarding Suzukis from the Other 4x4 forum and put them here; however, there may still be some floating around in Other 4x4.

Enjoy.

I am going to try to make this one thread a "tech only" thread without comments, simply quoting other sites/people for information (no links please, sometimes other sites move things and the links get broken) so that people don't have to hunt around as much. Post any strict tech you've got here.
Okay, I lied, I will include some links for those of you having trouble finding aftermarket or otherwise Suzuki parts:

Shifter
Q. Shifter problems/can't put it IN a gear or remove it from a gear.
A. Start with the shifter sheet. To remove it push down on retaining ring and turn CCW. Then pull shifter up/out. See vender list for new sheets, RR has new poly sheets...

1.3 Engine
-Pullys
Q. What pullies can I swap on?
A. Chevy Sprint 1.0L is a great swap, has stock water pump pully AND an overdrive for power steering, and other accessiries.
The 1.0L is also made by suzuki, so other vehicles with this or similer engines should work....

-Gearing Thoughts/Concepts..
Q. Which is better axle gearing or a t-case kit ?
A. While doing transfer case gears is probably the biggest bank for buck and a quick-fix, it is definitely a lousy way to try and create a reliable, trouble-free drivetrain. Think about this for a minute... You put on larger tires. Now your pinion becomes TWICE as hard to turn. This puts TWICE as much stress on the u-joints, the transfer case mounts, the transfer case itself, and the brackets on the side of the frame that holds the transfer case in place. "GEE I wonder why I need these big honkin' driveshafts now"...or "why do my bolts pull out of the transfer case on the long arm side"... or the mounting boss breaks off of the transfer case....or the short arm side bracket starts tearing off of the frame rail. "Gosh - maybe it is because I gave my transfer case almost 3 times as much power by putting in 6:1's and now it wants to do flip flops in its mounts because I must have FORGOT to change the ring and pinions relative to my tire size - which would have made the driveshaft easy to turn again and takes all of the strain off of these parts - like it was made from the factory when the little tires were on it." It is a MISTAKE to do all of your gear reduction at one point. Especially that far up the mechanical chain. Do yourself a favor...reduce the ratio at the ring and pinions relative to the size tire you want to run, then select the transfer case gears that will best meet your 4-wheeling needs. By going this route, you will have a well thought out and trouble-free drivetrain working well within the parameters of strain that the parts can and will reliably handle. -Brent (Trail Tough Products)
Year Differences:

* 1982. SJ-410 arrives in Canada. Basically the Samurai style vehicle that we have the love/hate relationship with. These beasties have the narrow track frame (front springs inset under frame rails in front), a 1.0 liter 4 cylinder engine (aluminum head, iron block. Want one? No seriously...), 4 speed manual trans with first gear ratio of about 3.15:1, 4th is 1:1. T-case is similar is design to a Samurai case BUT has a different casing, more squared off, no 4x4 switch, small flanges. Body styles are hard top (i.e. V), Pickup (K), LWB and normal soft top. Axles (4.10:1) are narrow to match the frame, differentials are same as LJ-80. Quick ratio upgrade is to get 4.56:1 ratio diffs from an LJ and plug them in. No parts interchange between these axles and the Samurai. T-case ratios are 1.58:1 in high, 2.56:1 (or so, bad memory, sit! stay!) in low.

* 1982/3. Same as above, newer style t-case housing starts to appear - very similar to Sam case with exception of 4x4 switch. Same ratios.

* 1984. Same as above except the t-case uses the same types of gear clusters as a Samurai case but with lower ratios (1.58, 2.5x). These gears are the ones used to make a "rocklobster" t-case (combination of these gears and Samurai gears to make a 1.58 high, 4.16 low t-case - web search for instructions). This may be the first "sanctioned" appearance of the SJ-410 in the US. Not 100% on that though.

* 1985. SJ-413 is introduced in Canada. Differences from a SJ-410: Samurai all aluminum 1300cc engine with Aisin carb and 5 speed transmission (3.652:1 first). Axles are changed to Samurai style diffs but with SJ-410 front brakes and 3.90:1 axle ratios. These diffs are intercahngable between Samurai and SJ-413). New Samurai style dash with no central console (the original style). T-case ratios change to Samurai ratios (1.409:1, 2.2x:1). Last year of pickup in Canada. US still recieves some SJ-410s, but not the SJ-413.

* 1986. First year of what we commonly call a Samurai in US and Canada. Canadian spec kept the Aisin carb (lenient emmisions reqs) while the the US got this fooked up Hitachi carbu-jector thing. Front spring spacing moved outboard of the frame approximately 2-1/8" per side, axles grew also to widen the track. US recieves soft top and hard top but not the pick-up or LWB versions.

* 1987-1988. Last year of LWB in Canada.

* 1988.5. First restyle of Samurai in North American market. New dash with a more car like center to house radio, heater controls, little cubbies, etc. Spring rates change (soften?). Canada gets the Hitachi carbujector.

* 1990. EFI on the 1300cc engine starts to appear (late 1990 I think).

* 1991. Last year for hard top, grille is restyled to two long horzontal slots.

* 1992. Last year of Samurai in Canada.

* 1993. Samurai is sold in US only without rear bench - to get around tighening security regs.

* 1995. Last year of Samurai in US.

There's probably more nitty gritty details I'm forgetting but that is pretty much it in NA.
More History:

1. In the beginning (Suzuki Motor Corp. History)



The ancestor of the Suzuki 4WD was called Hopestar ON360 and was manufactured from 1965 until 1967 by the Japanese Hope Motor Company. Its basic concept equals the later successful LJ 80 as in bodyline. Of course as all 4wd vehicles it was based on the grand daddy of them all, the Jeep (circa WWII). Foldable windshield, the outrigging front fenders and flat side body panels are some examples, as are the big tires when compared to the body. The tire/wheel combo came straight from the Willys. Those are the typical off-road vehicle trait marks of a classic 4wd vehicle. The power plant was an air cooled, 2 stroke, 2 cylinder, from Mitsubishi Type ME24D. It was 359 cc in size and developed 21 hp at 5500 rpm and maximum torque of 31.4 Nm at 3500 rpm. Only one version was available; convertible with a soft top. The wheelbase was 1.95 meters and the overall dimension were 2995 x1295 x1765 mm (length x width x height). It's weight was 625 kilos. In 1967, the Japanese Department of Transportation approved the Hopestar and the sale started in 1968. Only 15 vehicles were hand made in that year before the company decided to stop it's vehicle construction all together.


In 1968, Suzuki Motor Co. Ltd. acquired the production rights of the Hopestar ON360 from the Hope Motor Company. Suzuki, at that time, already was a renowned motorcycle producer and held several street racing world championship titles. It also had some car production experience but only for the Japanese market. Suzuki started exporting its 4WD trucks in 1974.


The prerequisites for mass production of a off-road vehicle were in many ways better at Suzuki than at Hope Motor Company. In 1970, the production of the Jimny started and in that same year Suzuki Motor Co. built it's one millionth car.


Before the first Suzuki 4WD roll of the a$$embly line, the engineers took a very close look at the Hopestar. All vehicle components were either reworked or newly designed. One has to take in account the engineering department had a difficult job as the Jimny had to be classified in the "mini-car" market segment due to tax issues which also meant that the engine size was limited to 360 ccm, overall length could not exceed 3 meters and it could only be 1.3 meters wide. After 2 years of development the first Jimny 360 (LJ10) rolled of the a$$embly line. It's body lines were very similar to of it's successors, like the LJ80 which 10 years later influenced the 4WD boom worldwide. The LJ10 was manufactured strictly for the Japanese market and had an air cooled 2 stroke, 2 cylinder 359 ccm engine with 25 hp at 600 rpm and a maximum of torque at 33.4 Nm at 5500 rpm.


To keep up with the mini-car guidelines, interior space ended up being somewhat scarce as the spare tire had to be installed behind the driver's seat making it a 3 seater. The LJ10 and it's successors were build this way until 1976 when the Japanese government made some changes to the transportation guidelines.


1972 marked the change over to the LJ20 model. The main difference was the power plant. It was a watercooled, 2 stroke, 2 cylinder 359 ccm engine with 28 hp at 5500 rpm and a maximum torque of 37.3Nm at 5000 rpm. This was also the time at which a watercooled engine and a metal hard top version were introduced. Minor body refinements were done in 1973. The combined single indicator parking light and turning signal were separated into two independent lights, one on top of the other, on the front on the fenders.


The "mini-car" guidelines were changed again in 1976 to a maximum engine size of 550 ccm, overall length was changed to 3.20 meters and the maximum weight was upped from 1300 kilos to 1400 kilos. Finally, the spare could be moved were it should be; on the outside gate, which means that the interior had room for a forth person. This new model, called the LJ50 (Jimny 550/SJ10), had a 539 ccm watercooled, 2 stroke, 3 cylinder engine with 26 hp, less than the smaller 360 ccm engine, but with a higher torque output of 52Nm at 3000 rpm.


1977 was a big year for Suzuki as it began to export its Jimny series. Parallel to the LJ50 (SJ10) Suzuki started to build the SJ20 with a 4 stroke 4 cylinder engine, later introduced to us as the LJ80. It had 797 ccm with 42 hp at 550 rpm and max torque of 61Nm at 3500 rpm (German specifications). At the same time fuel capacity is increased to 40 liters from 26 liters, the axle housing width was increased by 10 cm to 119 cm up front and to 120 cm at the rear. You can tell the 1977 model apart from the older ones by the raised hood with air inlets up front and the rear lights and bumper are integrated to the body. The LJ50 and LJ80 can only be differentiated by looking at the speedometer, as the LJ50 tops at 90 Km/h and the LJ80 at 110km/h.


Two years after introduction, the LJ80 received its last facelift. The headlight positioning was widened /lowered and the cooler grill was slightly modified. Also steel doors were offered for the first time. The LJ 50 was offered in Japan until 1983, eleven years after the debut of the Jimny. A complete model change was developed and the SJ410 (SJ30) was introduced.


OTHER FUN FACTS:
Did you know that Suzuki offered a 4 door version of the SJ30/40 in Brunei based on the long wheel base model. For the Japanese market (strict mini car guidelines) they offered a turbo version called the Jimny 660 EPI Turbo with a watercooled, 3 cylinder turbocharged, intercooled and fuel injected engine. It was 657 ccm in size and produced 55 hp at 5500 rpm and max torque of 85Nm at 3500 rpm with a compression of 8,1:1. It was offered with a 5 speed manual transmission or a 3 speed automatic. You can tell them from other similar Suzuki's as they have a air scoop a top the hood on the left side.

4. SJ specs


The first SJ model (SJ10) was the same as the LJ50. The SJ20 was more like the LJ80. The SJ410 (SJ30) had a totally diffent body.


The SJ was the first 'sammy-like' model. Some of it's original body panel designs are were used in the Samurai/Sierra bodies. In fact some people confuse the SJ410 with the Samurai/Sierra, however the SJ has a distinctive vertical slat grill. They were the first Suzuki vehicles to use a newly developed 1L 4 stroke, 4 cylinder. The SJ410W was the first Long Wheel Base Suzuki truck and incorporated a removable hard fiberglass roof. At over 4 metres in length it was put into service by numerous 3rd world counties as a military jeep. The LWB and Pickup models were not released until 1982.

Notes: Also came in Long Wheel Base (LWB) S/T and Pickup (Ute) models and in a 4 door version based on the LWB chassis


5. Samurai specs


The Samurai was the first Suzuki truck official sold in the United States through proper dealer channels. It's design was very much a carry over from the 1985 SJ410. So much so, that the 1986 Samurai's and 1984-95 SJ410's look exactly the same, except for body tags. In Canada it was introduced in the 1985 1/2 model year, in the US in 1986.


Depending on where it was sold in the world, the vehicle goes by three different names: Samurai (North and South America), Sierra (Europe, Australia and New Zealand), and Jimny (Asia).


In North America the Samurai was never totally re-modeled, but various changes have happened over the years. A long wheel base version, a SJ410 carry over never released in the US, was discontinued in other countries in 1987. JA and JX models were offered from 1986-90, JL and 2WD models were offered from 1990-94. The 1994 US models did not have back seats due to new safety regulations.


In July 1988, Consumer Reports ran an article headlined "The Suzuki rolls over too easily." Suzuki stopped selling the Samurai in the North America in 1994 after a sharp drop in sales in that the company blames on CU's test result. However, the Sierra and Jimny continue to be sold in Europe, Australia and Asia.


In 1996, Suzuki gave the Sierra and Jimny a face lift which renewed buyer interest. Many other compentents were upgrade and fine tuned, but the most popular Suzuki 4x4 ever still retained its narrow track and boxy look. The 1999 model year will bring a whole new look for the Samurai/Sierra.Jimny.

Other Suzuki Specs/Info

6. Sidekick specs



Created as a successor to the popular Samurai, but offering more comforts and modern components, the Sidekick proved very popular among young and old alike. Also marketed as the Vitara, Escudo, Tracker and Sunrunner, the "J Truck" was the first Suzuki manufactured in North America, at CAMI in Ingersoll, Canada, a joint venture between GM and Suzuki.


Initially only available in a two door model, a four door version was released in 1991 and began competing with Pathfinder 4 Runner, Trooper, Jimmy, and other SUVs.


In 1996, the JLX model was replaced with a Sport tag. Beige body molding, a new grill, and 1.8L engine was also added to give the four door a sophisticated look and feel. Duel air bags and a curvier dash was also implemented in 1996. The Sidekick/Tracker placed second in the compact sport utility vehicle category in the 1996 J.D. Power Initial Quality Survey.


1999 models will see the first major body restyle since its introduction in 1988. The Sidekick name will be retired and the Vitara moniker will be used in North America. North America will also see the V6 option. Stay tuned for more info as it become available.

7. X-90 specs


Is it a mini-truck or a 4x4 car with a t-roof? No one is really sure what the X90 is and it's so new I don't think anyone has had the time to take it about to find out. It's 4 wheel drive mechanism is pure truck, unlike it's competition, the RAV4. Currently the X90 is only available in a two door, two seater model, but there are rumours Suzuki is looking at adding a 4 door, four seater, hatchback model to the line.

Ring and Pinion Install Text:

After receiving you new gears, check both boxes and contents and make sure all nec. parts are there double check ring gear and pinion for matching numbers, be careful not to mix gears R/P are matched. Wash all gears in a solvent i.e., mineral spirits brake clean what have you. Start by removing the old ring gear from the housing clean it and check bearings and races, it is not always nec. to replace them if they are in good shape but if in doubt replace, also do not mix the carrier bearings and races up. I like to wash each side down and set them in the packing material that the new gears were shipped in, in the correct ref. that they were removed. At this point all parts cleaned and visually inspected you should have a setup similar to this, notice I have already installed my new ring gear using lock tight and installing bolts to correct torque spec.(note: if this is your first gear installation use some marking compound on the ring gear and rotate gears in both dir. to get a Visual feel for what your pattern should look like when new gears are installed)


Next in order would be to use a depth gauge micrometer and get the depth on the existing pinion in the housing, it helps as a reference for installing your shims on the new pinion for depth. write this # down for later use. Next remove the pinion from the housing and clean if bearings are good remove them with a Bearing splitter, a press is recommended But a vise, wood block and a good dead blow hammer have been known to be used. Next take the depth measurement marked on the pinion head and compare to the depth recorded during disassembly add or subtract the difference to match the new specified depth. Install new pinion into the housing I like to use the old crush sleeve initially while checking for correct depth. Once your depth is achieved, reinstall the carrier and new ring gear into the housing. Start by turning side adjusters in on both sides checking Backlash with a dial indicator turn adjuster in or out to achieve the recommended backlash once this is done it 's time to check you wear pattern. Apply a small amount of gear oil onto a piece of cardboard and mix in some marking compound, brush onto face and heal of 4-5 teeth on the ring gear. Rotate gears until a definite pattern starts to revile it self (mental note what did it look like when you checked your old gears. If the pattern looks good I disassemble, install the new crush sleeve and start torquing it down. Remember it can take up to 400 Ft.lbs to even begin to crush the sleeve but once it starts preload comes up very quickly so take it slow I use a pc.of 2x2 angle and bolt it to the pinion flange and use a breaker bar to get started, periodically checking preload with an inch lb.dial indicator until the preload is to spec. Once the preload is set on the pinion I reinstall the carrier set it up to proper backlash again then start tightening the side spanner disks as tight as you can get them periodically recheck backlash and tighten the corresponding spanner to keep backlash to spec. From every one I have talked too there has never been a gear failure in this style carrier due to over preload on the side bearings. Frankly, I don't think you can over load the carrier bearings unless you use a 5' breaker bar on your spanner wrench. Anyway after you feel you have a preload on the ring gear and your backlash is still correct, Brush on some more marking compound and double check your wear pattern if it looks like the correct diagram below you should be good to go. Also remember quality diff oil and correct break in period based on your gear mfg. spec and they should last you a long time.
Welded Axle Write-Up:

Welding differential side gears is a method of creating a locker that allows for far greater traction than an open differential (common on stock vehicles) or even a limited slip differential (commonly known as a posi traction device).


Although welded diffs may not be the ultimate way to lock your differential, it can be the cheapest if you know how to the work yourself or know someone who can do it for you cheap or free.


There are different ways to weld differentials to create a locker. Some are created by welding the side gears to the spider gears. This eliminates the differentiation of the open differential as the spider gears and side gears no longer move independently but as a single unit. Another way, which may be considered stronger by some, is to weld the spider and side gears together, and then weld them to the differential case (some people even had pieces of metal to this process in order to make a more solid a$$embly weld). These two examples do not allow any differentiation at all between the two axle shafts, and consequently the wheels and tires.


In the example pictured here, you will see that only some of the valleys in the side gear teeth are filled in with filler metal from a MIG welder. This is to allow a small amount of differentiation between the two wheels on that axle a$$embly. This can make it a little easier to steer in tight situations on the trail. It also makes it easier to unlock manual lockout hubs. A fully welded diff will often bind up the drive-train making it difficult to unlock the hubs.


The procedure pictured here is being performed on an '87 Suzuki Samurai rear third member. First the third member is removed from the axle a$$embly housing (first removing the axle shafts to allow removal of the third member). Once the third member is on the bench, it is marked with a punch so that the parts go back in their original orientation (this is very important).


Once disassembled, the side gears are cleaned thoroughly in solvent. Now they are ready to be welded. The choice of welding process is primarily based on what is available at the time. Welded diffs are often referred to as Lincoln Lockers because they were commonly welded with Lincoln stick welders in the past. These days a lot of 4wheelers have MIG welders and they work just fine. You could even use TIG if you have that available and feel comfortable with that process.


Once the appropriate pattern and number of valleys to be welded have been determined for any particular application, the welding commences. In this case our secret tech monkey filled the gaps to the top of the teeth ridges, then ground the welds flush with an angle grinder. He reassembled the carrier and third member, then checked the ring and pinion backlash and contact pattern.


With the third reinstalled in the Samurai, I was able to traverse many new obstacles with the added traction. With the welded rear, I experienced wheel chirping on pavement, and accelerated tire wear. With an open diff I ran 20-22psi in the tires, but in order to minimize the chirping and tire wear effects of the locker I started running 30psi.


Ideally you would want to install a full carrier replacing locker such as a Detroit or ARB locker or even a spool to get the most strength out of the unit. On the other-hand, if you don't have a lot of money, and don't mind the possibility of breaking the carrier or related parts (nice to have spares) then this is a cheap way to go.


Note: The pattern welded on the Samurai side gears are in a double wing butterfly pattern because the Samurai differential uses four spider gears

What are the biggest tires I can run?

[Noel Van Hook]



Height: Pure stock with biggest you can fit is 27". Mickey Thompson and Interco both make nice 27x9.5 tires that will fit stock no problem. A 215x75R15 will fit also. People will say you can go bigger, but any larger will rub under full suspension compression! Lots of people don't care about that, and so put 28" tires on anyway.



With a 1" shackle lift (2" longer shackles) and minor trimming on the front bumper you can fit 29" tires. This includes 235/75R15 tires. Trimming is easy. It can be done with a hacksaw, and is done on the inside of the bumper, so it doesn't show. The shackle lift is easy too, and 1" is small enough that the stock shocks will work.



Width: Pure stock the widest you can go is 9.5". Any wider and you rub the bumper when turning the wheel. With minor bumper trimming (see above) you can go to 10.5". You can use standard 3.5" backspacing and you'll still clear the springs at full turn.



What I have: I run 29x10.5 swampers on 15x7 wheels, standard backspacing. To get them to fit I added a 1" shackle lift, and trimmed the front bumper. No fender trimming was required. They do not rub, ever. The truck has a nice wide, aggressive stance. The wheels hang out about an inch from the fender flares, so they do tend to throw the mud around. But they also do a good job of protecting my fenders from damage, too.

What mods should I make to improve general trail-worthiness if I only have $1000 to spend?

[Mike Graham]



When I asked this question, I got several different answers to this one. Here they are:



Jonathan Hall says: "Lock right, s/o, diff gears."



Noel VanHook says: "Rock Lobster and tires."



James Hiers says: "Rocklobster transfer case and lockrite."



I'm going to amalgamate these answers and come up with a different one. I'm going to say that for general trail running the best $1000 spent to keep you moving is going to be spent on a lockrite and tires. A rocklobster is a great thing to have if you're playing on steep rocks, but a locker and tires is the best $1000 you're going to spend for general trail use. If you're building a rock-crawler, then the rocklobster and s/o just might be your best route, but never underestimate the value of good tires. Oh yeah, I'd put that locker on the front. Now, if you're planning on putting big tires on it (like 30s; see the section on tire sizes) then you may well be better off going with Noel VanHook's suggestion of tires and a rocklobster, because the increased tire size is going to reduce your torque, which the rocklobster will compensate for, both on and off road.

How… ?




2.1
How tough are Sammies?

Although many of the drive-train components are tiny to the point of being "cute", they are more than strong enough for the stock engine. When you start swapping in bigger engines, or increasing the power of the stock engine, and then start hurling your Sammy down boulder-strewn passages that a mountain goat would think twice about attempting, that's when you start breaking things. Of the stock drive-train components, the only consistent breakage (and again, this is only in extreme situations) is u-joints, and even then only certain people, like Glenn Wakefield, break them regularly. I think it's a Karmic imbalance thing. Cool There have been reports of aftermarket diff gears breaking if they're not set up just right.



2.2
How do I get more power out of my 1300cc engine?

[Mike Graham]


Whether the engine is fuel injected or not, it can benefit from:


K&N air filter ($50)

MSD Ignition system

Tri-Y exhaust header

2" Free-flowing exhaust

Performance camshaft


The favorite seems to be the header and 2" exhaust. Almost everybody asked put that in their top 3 mods to make to a 1300.



If the engine in question is carbureted, then look into replacing the stock carb with a Weber.



2.3
How do you get the @#$& valve cover off?

[Mike Graham]



When the crank is turned by way of the crank pulley center bolt (using a 17mm socket) to the TDC point (the white notch on the crank pulley is lined up with the "0" on the ignition timing marks), then the intake valve rocker on cylinder #4 will be enough out of the way that you can raise the front of the cover (after removing the bolts, of course) and roll the cover to the right to sneak the back left corner out from under the vacuum advance on the distributor. Getting it back on is just a real drag in the dirt.



This is going to sound excessive, but I honestly find it easier to pull the distributor. Really. Firstly, use a scriber to make a mark on the dist body and the mount, so that you can easily realign it. Once you have the crank at TDC you just remove the distributor hold-down bolt, and the whole unit slides up and out. Even if you don't want to actually pull the dist, you can just turn it clockwise a few degrees to move the vacuum advance out of the way, and you will find that life is much, much easier. This is far easier than screwing around trying to get the cover off with the distributor in place. When the cover has been replaced and bolted down, just turn the distributor body back so that the marks line up again, and tighten the hold-down bolt. I usually check my ignition timing afterwards, but you can get away with not doing it if you line your marks up correctly. If you later decide to permanently change your ignition timing, just sand off the old marks, set the new timing, and make new marks.



2.4
How do I relocate my breathers?

[Mike Graham, with info from Thom Batty]



Get yourself 15' or so of plastic tubing with an inner diameter of ½". Using a pair of vise-grips, remove the cap from each breather, attach the end of the hose and fasten with a hose clamp. Using zip-ties, run the hoses to the engine compartment (leaving enough slack near the axle for axle travel) and cut off the extra hose. You can end the hose in one of two ways; either spend the money on some inline filters (fuel filters or whatever) and top the hoses with that, or just end the hoses in an arch like the top of a candy cane; if the open end of the "candy cane" runs down about 8" or so, you won't need to worry about water getting in. Higher is better. If you run a snorkel, then just plumb the hose into the snorkel so that it uses the same air supply.



2.5
How do I get the slop out of my steering?

[Larry Harris]

There is a lock nut and adjusting screw on top of the steering box. The proper way to adjust it is with the preload method. You will need a spring scale to measure the starting torque of the worm shaft (the one with the rubber piece that goes to the steering shaft) it should be between 1.58 - 2.63 kg when adjusted properly.



There have been many that just turn in on the screw a little to remove the free play. Be careful with this method, but it does work. Do not over-tighten the screw. Make a small adjustment and cycle the wheel from stop to stop and make sure it still has free travel with no hard spots.



2.6
How do I re-center my steering wheel?

[Larry Harris]



The steering wheel can not be re-centered unless you remove the wheel itself or the u-joint on the steering shaft. The only adjustment we have is for toe.

To remove the wheel, pull off the horn button and loosen the nut holding the wheel in place. Don't remove the nut completely, so's not to bop yourself in the nose with the wheel. Pull the wheel free (a puller is not required). Remove the nut, reposition the steering wheel and fasten it back down.

Why… ?




4.1
Why does my Samurai hesitate when I accelerate?

[Gary Munck]



The secondary throttle plate is operated by vacuum, there is a little hole that is the port for this vacuum.



The flat spot you are feeling is caused when the secondary either does not open or opens and then closes partially as the vacuum drops in the manifold. I hope this clears up the mystery.



On most carbs it is necessary to move the opening of this port out into the air flow. There is a small tube available that can fix the problem in the majority of Samurais.

4.2
Why does my shift lever wobble around?

[Off-Road.com]



Because the locating pin that's supposed to hold it in the proper position has broken off. You need to replace it with a new one, both an easy and a cheap fix. See:



http://www.off-road.com/suzuki/samurai/shiftlever.htm



for full details.



4.3
Why is my shift lever stuck?

[Mike Graham]



Because the locating pin that's supposed to hold it in the proper position has broken off and things got way out of whack. See 4.2 immediately above.



What is actually happening is the toe of the shifter is caught somewhere it isn't supposed to be, and can't get back. The solution is to remove the entire shifter a$$embly.


Now look into the gearbox. There are metal bars running front to back. There are notches in the bars that should line up to form a channel from side to side. If they don't, then get a big screwdriver and poke them around until they do. The channel will line up with the notch in the reverse gear spring.


Once the channel is lined up, just reinstall the shifter.



4.4
Why is my t-case selector popping out of position (or stuck)?

[Off-Road.com]



Because the "sheet" (as Suzuki names it, a piece that guides the transfer case shifter) in the transfer case has worn out. Order a new one and replace it. The part number is 29541-80051.



4.5
Why is my fuel pump leaking oil?

[Off-Road.com] [How to replace it yourself]



It's shot. And it'll leak a lot of oil, so keep a close eye on the engine oil level until you get it replaced.



4.6
Why should I put a locker in the rear axle before the front?

[Don Schultz]

There are a couple of compelling reasons for installing your first locking type differential in the rear axle first:



1) Much of a vehicle's weight transfers to the rear wheels when driving up steep hills. This places most of the burden for climbing traction on the rear wheels. The shorter the wheel base, the more pronounced the effect. Under extreme conditions you can't afford to lose any traction on a back tire, even in 4wd. A good driver, with a suitably equipped 2wd and locking rear axle, can go places thought only accessible by 4wd.



2) If you are like most recreational 4x4 drivers, you spend more time in 2wd on the street than in 4wd off-road. With a locker in the rear your vehicle benefits from the added traction in both on and off-road service.



Note: Please don't misunderstand. I like and own front wheel drive vehicles but... there's a myth floating around that front wheel drive vehicles climb better than rear wheel drive vehicles. This is only because the rear wheel drive vehicles that were tested lacked positive traction (a locker) to both wheels. The same laws of physics apply to towing. That's one reason why rear wheel drive vehicles in general are used to pull heavier loads than front wheel drives.



Bottom line for 4x4'ers... two lockers are better than one, but if you must choose, stick it in your rear!
