Well I found the source of my noise which I thought was a wheel bearing. Turns out it wasn't a wheel bearing but a bearing none the less. It's the steady bearing on the propeller ( drive ) shaft. So far I haven't found a replacement bearing and dealer wants to sell me the whole shaft. Going to bring it to A+ driveshaft next week to see if they can part source the steady bearing, if not I'll have to make a financial decision on a junkyard shaft or a new one. GM#42529901

What kind of noise you getting? Like a droning noise that resonates through the whole vehicle?
