Rear pinion seal

quick question. i had a leak in my rear differential where it connects to the driveshaft. so i replaced the seal. however hopping out under my baby today, i saw the leak was still alive and well. any ideas as to what the problem may be? i have a 1998 wrangler. dana 35 rear. any ideas (especially good ones) :P would be appreciated. thanks.

cheers,
Greg

Did you reuse the same pinion nut? If so it must be torqued correctly and you need to use locktite on it.

It is suppose to be a one time use only nut. But can and has been used by many again with proper torque spec and locktite.

Should be torqued to 160 to 180ft pd.

also...when you removed the old seal you didn't scratch up the housing did you? even a little gouge in it will jack it up.

Well to check you have to pull the new seal you put in out.....where the seal seats into the housing must stay smooth.
