So I have a 2007 Yukon Denali with 175k on mileage. The seal is leaking and a local mechanic said it will be in the neighborhood of 2 grand seams a little high to me what are your thoughts?

Damn I live in dallas tx. Looks like I need to shop around. I considered doing it myself but I'd rather pay someone on this job.

I have a '07 Yukon XL with the 6.2, ~150k miles, the rear main seal has been leaking for over 5 years, got some quotes to replace the seal of $700-$800 which seems fair since they have to drop the trans to do it right. I'm a DIY'er, been building motors for many decades and just not worth the effort to do this, so I am going to have someone else do it.

Couples of questions:

Heard that the oil seal bracket is probably cracked? Is that the whole seal cover they are talking about? If so, then that needs to be a part I have ready for when they do it.

Thinking about it, would it be a good idea to have the trans freshened up when this is done since it will be down? My thought is that I don't want to touch the trans until I do the rear main seal, do them both together.

$700-$100 around me considering you have to drop the trans. It’s almost all labor. I did mine while I was replacing the trans as preventive maintenance. It’s easier to replace the rear cover and seal as one piece. It’s not a “bracket” and doesn’t break but it does have its own seal between it and the block which can leak.
