whys my rearend leak???

Some pepto should do the trick.... it happens to me alot after buffalo wings

Ok, I am going to be a smartass and explain why your rearend is leaking.. Actually I will just show you

someone beat me too it....last time my rearend was leaking the doc gave me some penicillian

My last post I was talking about the professional way to do it. This applies to most integral carrier differentials. There is other ways to do it, perhaps the most accurate would be to use a 1/4" torque wrench that has a dial gauge up to 200 inch/lbs. remove rear wheels and brake drums, and drive shaft, turn the pinion shaft with the torque wrench at a constant rate and read the quage. Mrake the relation between the nut and shaft so it can be returned to the same spot. You can now re and re the pinion yoke and seal, inspect the yoke for any damage that may have caused the leak. Do not use an impact gun to tighten the nut. Tighten it in stages checking the rotational torque with the torque wrench frequently until you reach the original torque reading from before disassembly. Do not overtighten as you will crush the crush sleeve further than spec and you will have excess pinion bearing preload, which could cause noise and failure of the pinion bearings.

If it is your "Other" rearend, get to the doctor!!!!!
