I have a 2004 ford explorer with a front differential leak its not coming from the differential gasket and I confirmed this by dropping front diff cover scraping old gasket and made a new one with RTV and same as before the leak is coming from the driveshaft seal and its a very slow leak. Firestone diagnosed it almost 2 years ago but it barely drips. Can anyone tell me how difficult this job would be. Might be something for my mechanic if I'll be disconnecting drivelime components. Has anyone had this done?

Of course, we've been replacing pinion shaft seals forever. Requires knowledge of pinion bearing preload, no guesswork, unless you are willing to chance making hamburger of your front gears. Keep in mind, there are 4 places leakage can occur, and that driveshaft spinning along with wind draft, can make it look like oil leakage is HERE, when it's actually THERE. imp

Thanks my 04 and I appreciate it. What four places can leakage occur and just so I can get an estimate in my head of labor costs how many hours do you think this job should take?

@corkey
Yeah, you're right. I meant only 4 places because I don't think I've ever seen a failed plug hole! imp
