Default Pinion Seal leak


Second front pinion seal in 4000 miles. Replaced the first one with a Duralast and it was leaking again within a few days. So during the last oil change i decided to try a Delco pinion seal
and it seems to be bone dry now. Second time I've been bitten by non Delco parts, maybe someday I'll learn!
Also, went ahead and dumped my F150, The 2007 H3 is my daily now and I love it!

Nice work!

Sorry to hear you got boned by the Duralast. I just put a Precision pinion seal on my front diff (during a rebuild) so hopefully it holds up.

The H3 is a baller as a daily driver

It looks nice. Did you paint the front bumper?

Nope, found it like this. The guy I bought it from wasn’t driving it because of some hardcore misfire issue. It was just a wire grounding out, runs great now!

Did you get a good deal? -How much did you pay for it?
