Rear tire cupping/scallopping

Even after two new rear shocks, a camber kit (ie, Moog upper strut bolts with elliptical cam) and multiple alignments, my left rear tire still makes a "whomp/whomp/whomp sound, and the tire gets scalloped after some hundreds of miles. Some background: several years ago I slid the RIGHT side into a curb during an ice storm. I drove home (2-3 miles) on ice/snow, with the right rear wheel bent in and not in line with the other 3 wheels. The car would swap directions, sometimes tracking with the left rear, sometimes kickedc out sideways, tracking on the right rear and dragging the left rear.
Repairs on the right side included new control arms, strut, etc. nothing was done to the left side. Chevy dealer claimed that there was no "frame" damage, but something is not right. Multiple alignments have been done, the most recent where I told Firestone about the toe-out, and supposedly they compensated. I installed new Moog sway bar bushings over the weekend, that didn't make any difference. I'm wondering if it is the OEM bushings on the control arms on the left side are faulty that is allowing the left rear tire to toe out, or if the subframe is bent in some not-obvious way. any comments / thoughts /previous similar experience ?

Dunno if you could try taking it to a body shop that offers free estimates and have them look at the frame, that way at least you would know if there is damage there. That is what I would probably do with it if it were mine. Wouldn't keep throwing money at it trying to fix it only to find the chevy dealer was wrong.

My 6 year constantly asks why. What adults can learn from 5 and 6 year olds, to listen with your ears and mind open. Hard to learn when you don't listen ......

Did you get an alignment print out after it was done? Shop should be giving you a print out of before and after specs showing what was out and how much they corrected. If you have one, post it up so I can see it.

I am wondering if the hub bearing is trashed... A reputable shop and tech should have discovered this before doing an alignment. I would like to believe this wasn't overlooked... I would assume the tires on it now are not the ones on it when the accident occurred? If there was frame damage, it should show on the alignment​ check. Hub, knuckle, tire is where I would start... An alignment printout would be helpful.
