You've got me on the clunking noise. You've replaced the mounts; that'* the likely culprit. Can you get this noise on video?

It could be a bad CV joint (axle) if there'* a clicking sound along with this, but I'm going to put my money on the hub assembly.
The standard GM Forum test for this is to jack up that side of the car and get the tire at least an inch or two off the ground. (Be safe: chock your opposite rear wheel, use a jackstand if you have one, apply the parking brake, all that good stuff.) Now, grab the tire, and shake it in all directions. If your wheel moves side-to-side, it'* a bad hub or a bad tie rod end. If your wheel moves up and down, it'* a bad hub or a bad ball joint. Ideally, there should be no or very little movement.
If the car is in neutral instead of park, you can also try rotating the wheel by hand to see if you can hear or feel the noise.
