    pinion nut is 210ft/lbs.



    preload is 15-35 in./lbs. for new bearings

    The torque on a crush sleeve is different than a shim type. The 9.25 uses a crush sleeve. Torque the crush sleeve to get 18-20 inch pounds of preload on the pinion.

    FYI: It's ALOT more than 210 ft. lbs.



    At 250 ft. lbs. the slack wasn't even pulled out of the bearings. I had to keep an impact wrench on it for a while until the sleeve crushed.

    I only wasted 1 crush sleeve... :silly:



    Seriously, I couldn't get the sleeve to give any other way....On my second attempt I had the routine dialed and got the preload right on... :bigthumb:



    Thanks again for your help.

    I was glad to see that my D60's that had crush sleeves originally now use shims (aftermarket gears)....I hate crush sleeves.

    What's up Bill?



    I actually read somewhere that someone made a spacer to eliminate the crush sleeve in the 9.25 but I couldn't find it anywhere...

    You shouldn't reuse the crush sleeve or the pinion nut and I'd put a new pinion seal on too while you're there.



    I'm guessing you'll have to pull the whole carrier assembly out to set the proper pinion preload...Then set the whole thing back up again... :wall:

    Get a new pinion nut and seal. Remove old nut, seal and yoke. Install new yoke, seal and new nut. Tighten new nut until all up/down, in/out and up/down movement is completely gone. The pinion should turn with some resistance.

    I thought you wanted my wheels and tires on my 40" MTR post? You can't use the wheels without a swap, thats where I got that from though.



    If you want to upgrade your tires to 37's (37/12.50/17) though, I may be swayed......lol

    I was just giving you grief because you just bought the 37's...I'm swapping the gears in my half tons so it'll be a while before I even consider swapping axles. :bigthumb:
