Unfortunately no Pro, I actually just came inside from spending more time under it to try to figure out what it is.
For one, my wheels bearings need to be replaced or repacked AGAIN. Two, my sway bar end links are junk and last but not least, my upper steering shaft moves quite a bit. Oh and my steering wheel speed sensor seems to have been a defective from the manufacturer because nothing changed after installing the new one.
Well, off to repack my bearings for now then off to the parts store for end links, thats after I go check my control arm bushings. I have new ones just waiting to be installed.

Hows your Tahoe? Looks sick, as ussual ;)
