Re: leaky differential
Yeah it's the pinion seal. Just did mine 2 months ago. Not too terribly hard to do. Just be careful not to overtighten the nut. Otherwise it's just another seal

Re: leaky differential

Re: leaky differential
Definitely change the fluid. Make sure how much to tighten it first though. Too loose = bad too tight = also bad. Just the way it was when you took it apart = happy differential. It's not difficult, just have to pay attention.
