AWD Denali front end noise

Recommended Posts

Well I have a 2004 Yukon Denali that seems to have the dreaded front end noise associated with carrier bearings going out. I called a few shops and they want between 600-950 to replace all the bearings in the front end and that just seems insane to me. I was wondering what was the normal going price to have this done. I also thought about buying a used differential and swapping it in, but a used AWD case is not cheap so here is my thought:


Can I just buy a 4wd front diff and swap out the passenger axle tube from my AWD diff to it and run it? Is there anything that I should replace while it is apart? Just wanting to make sure I have the right idea. I can get a 2001 diff with the correct gears out of a z71 for 275...

600 to 800 seems to be the going rate. I got it done a little cheaper, but just because I had a buddy who did the labor (GM master tech) and I got the parts for cost. IMO, you woulld be better off just rebuilding your own and be done with it. And put some good synthetic gear lube in.

600 sounds reasonable, but 950 sounds steep. Just a couple hundred or so in parts, plus gear oil. Most of it is labor. Just make sure it is a mechanic that is schooled in setting up backlash in the ring gear. Good luck!
