Wierd Clunking Noise in Rear, Acura CL

How the hell does hard set, suspension settings magicly change location to location??

Shaking the wheel doens show for sure a wheel bearing is shot. They are such a tight tolerance item, if they are bad enough to make noise, pull the car one way or another, they can be warn just enough that you will never feel it in hand, yet the wheel being 25+" in dia, puts the tread 12+ inches away from the bearing, so every mm. the bearing could slop would yield 12+mms of movement. If you lift the car off the ground and can shake the wheel, it would be death to drive on the road!

check the dust shield like he said, look for any slightly polished edges on its rusty surface, if it hit something rotational it would clean the rust off it. if you see something like that yank it away a bit.

If the caliper sliders are frozen you would eat one pad wayyy more than the other. you should be able to mount the caliper on the car without the rotor and slide it side to side without much effort. if it doenst replace them.

Bent wheel wouldnt make those noises, but could cause the pull, vibrations, and if it is out of balance enough will kill a wheel bearing over time.
