Thank you
I jacked up each wheel and ran in in gear in the air. listening....Very
smooth and quiet sounding, unlike last time I had a bad CV or wheel
bearing, when it sounded bad. I think things at the rear are fine for
now...
During my inspection I found one of my upper control arm bushings is shot
and also my other side front wheel bearing sounds and feels a bit worn...
