rear output shaft seal (pissing me off)

Recommended Posts

Awhile back I noticed some atf on the bottom of my truck just above the front u joint of the rear driveshaft. Anyways last weekend I replaced the output shaft seal by removing the rear driveline, tried to pry the seal out to no avail so I removed the extention and smacked it out from the front end, no biggie. Installed new seal, then the driveline, filled up the transfer case and called it good. I cleaned up the previuosly leaked fluid from the underbody. Now there is fresh fluid there so I am sure it is still leaking. The sliding yoke did not feel like it had any abrasions where it rides on the seal ?? My t case says its a model 242 but the dude at the parts house said the one I need was for a 241?? I measured them with a caliper and it seemed to be the one. Why is it still leaking ??:banghead:

had similar problem in the ranger. turned out the brass bushing in the output housing was scored and worn. even had to get a new yoke.

My driveshaft likes to grab the rubber part of the seal and shear it from the metal part. I am on the 3rd one now in 100k, all of them sheared. This time I completely packed the rubber part with grease, so far its holding up good.

I always lubed mine before I put them in. Takes time to get the oil back there some times

Yeah you can barely get any in there. Yesterday when I had the whole tailhousing off I absolutely packed it :lol:

Pretty normal, I have yet to see one that was totally dry. As posted the bushing could be loose. my 02 I bought at 18 k and currently at 118 k has always had a drip of oil hanging odd it but it has never left a puddle. I think I replaced the seal once but it didn't cure the hanging drip. Nothing to worry about until it leaves puddles.
