Hey guys - in May of this year I purchased my neighbor's 2003 Yukon XL 1500 SLT with 95K on the odo. It's a super-clean Yukon and she did a decent job maintaining it overall. It has some front axle issues, however. Specifically, it makes a horrible grinding noise that is definitely something to do with rotation, as it is speed-dependent.
I'm mechanically inclined and I can do all the basics on a vehicle and a little more on my own, but I've never worked on an axle. So, I had my friend that's a certified mechanic check it out for me. The initial issue was a fluid leak, as one of the seals had dried up/gone bad. He initially replaced the seal and drained/refilled the fluid, but the noise did not change. Next time he went into the axle, I told him to just take care of anything that looks obvious, so he replaced the other seal(s) and changed out all bearings/races on the axle as well as the outer wheel bearings, both sides. All bearings needed replacement - they looked pretty bad. He said the spider gears and everything else seemed to look excellent, so he put it back together and refilled the fluid. Of course - no change.
My friend hasn't had the chance to look at it again due to some other time commitments he has, but I'm wondering if I should just hire a specialized shop that has the proper listening tools to get a better diagnosis. I hate spending money and time on replacing parts "in the general area" to hope it turns out good.
Ideas?
