Rear End Leakage

Great Site!

97 EXP EB 5.4 100Kmi

My diff is leaking fluid at the input yoke. Is there a seal that can be replaced from that end or am I in for a rebuild on the diff? If I do need a rebuild what is the price range for something like that? Does the dealer have to do it or can a private shop like Goodyear or Firestone auto centers handle it?

Thanks for helping a newbie out! I have been watching this site for awhile and getting valuable info. Keep up the freedom of information!

Jon

Rear End Leakage

I read somewhere that a clogged vent may cause this problem.
Have you checked yours?

Just a thought, good luck!

Rear End Leakage

Hi budmanbusfan and welcome to FTE

It sounds like your pinion seal is leaking.
It's about an hour or so to replace it. A private shop can replace it but seeing that I work at a dealer I would have to recommened you take it to a dealer
If they shop doesnt know what they are doing they can destroy the pinion bearings, either by over or undertightening the yoke nut. There is a crush sleeve that adjusts the bearing preload and it has to be done properly.
