New guy here, not new to GM trucks but new to the Cadillac world.
I just bought an 02 Escalade with 140k on it, needed a transfer case when I got it. We did a t case, then I noticed a slight vibration and noise from the front front diff, I had my mechanic do bearings in it, it doesn't have any vibration now ( I can't feel it in the wheel anymore) but now I have a humming noise..... he said it is pinion noise, he said most GM AWD trucks do it? Even if it is "normal" is there a better gear oil to run in there to keep it quiet? I think he only did the carrier bearings in the diff, should I have him take it apart and do the pinion bearing too? Damn noise drives me nuts!!
We did change carrier bearings and seals as well as all the u-joints on the truck, I think the noise I have is pinion noise? I did drive my buddies Yukon Denali XL and it had a similar noise but not as pronounced. The noise just drives me nuts and I'll more than likely pull the whole front diff and swap it out for another complete unit.
