You are right, I am glad that they are holding up, but only another inch all the way around can't hurt that bad. (maybe)?!
What will be put under the most stress with 40's. I wouldn't even condier this if I didn't work at a parts store and have friends at the Dodge dealership. I get everything about 30% off list price. If my axles, bearings, etc. won't be put under that much stress I wouldn't hesitate. I don't care if stuff like that wears out, I just don't want to break anything 4wheelin. My main concern is the diff., axle shafts, and U joints, and yokes etc.
the things that would be put under stress would be pretty much the whole axle. do you do any offroading now? about the only thing 40's are good for on 1/2 ton axles is a show only truck.
lets start with the back axle.
1st.. can only go to 4.56 gears, so unless your motor is making atleast 350hp , its gonna take its toll on that. then since you cant get 4.88's or 5.13's your tranny is going to take alot of abuse.
2nd..the 9 1/4 all ready has bearing problems in the pinion area, putting bigger tires on is going to put more leverage on them.
3rd.. its a c-clip axle, im sure you dont want to have the grove the c-clip rides on to shear off and have your 200# axle and tire assembly to fly off going around a turn or such.
4..the problem of having a #200 tire/rim combo on 1/2 wheel studs(though you could upgrade to 9/16 studs)
5..someone correct me if im wrong but doesnt 3/4 and 1 ton axles have bigger brakes? i know with only 36's sometimes its a white knuckle ride trying to stop.
and for the front its pretty much more of the same exept the dana 44 isnt a c-clip axle.
there is a guy who has/had a website about extra tall trucks, maybe some of you have seen it. a dude from Hawaii named Keoni. i think its a 1997, blue with white stripes, club cab, that has a 318 that pushes 40's.
i had emailed him when i started looking at lifts and tire sizes a few years ago. he said he was having alot of problems with the axles because of the tires. BUT the truck did look awesome though. grant it i dont know how much offroading there is in Hawaii but other than beach(im not being sacastic).
