2007 with 205,000 miles.
Recently acquired a leaky rear pinion seal that I replaced myself - I used the procedure found in the pdf for the differentials found on Schwarttzy's website.
All went well, except I discovered there was a sealing surface sleeve (name?) on the yoke that the seal seats on. I'm sure it's designed to be the wear item instead of the larger yoke.
However, no parts stores, and not even the dealership listed this part. I used my old one out of necessity, and it still worked (no more leak), but I'm wondering if this is even available? Maybe it's just a generic part I'm not familiar with....? If it starts leaking again I'm going to want to replace it...

Also, the parts store listed two different seals. I bought both to be sure, but is the difference the locking rear differential (which I don't have)?

 

Answered my own question after a lot of searching. Advanced Auto has these:

Yeah, I was gonna say that......

Actually I did not understand what you were describing, but I get it now. Thanks for following up.
