Have issues lately, there was a loud bang/clunk from rear right over bumps also noticeable shake from rear between 60 and 75 mph, it has since gotten louder and shaking worse. Inner rear tires badly worn on both sides, so i changed tires and upper control arms (PITA compared to the sedan because of the airbag) anyway, noise didn't go away but there was little to no shaking coming from the rear
Now i cant drive my car, feels like my rear tire is oval shaped, car shakes violently at any speed over 40, clunking and banging over the smallest bumps. Checked tires and they are fine, i think its subframe bushings or lower control arm bushing
Anyone have this experience? my indy wants $1500 plus in labour to change $180 worth of parts...SMH

Are you asking what could be wrong? If your Indy gave you an estimate then you should already know what's wrong. If you need another opinion just take it to someone else or lift the rear and start pushing an the wheels and tires to see what the issue could be. It is hard to diagnose suspension issue over the internet. You need someone there to actually see what is going on. If you're to the point of changing control arms then you should be changing all bushings and links.

Did your indy mechanic not provide a detailed list of what needs to be done? Mine always does. Please share those details if you have them.

So you weren't having the issue before the control arms. If so check your work. If not how many miles are on the car? Bushings go bad eventually but it depends on the driving habits and roads you drive on daily. Have a look at them and see if they are worn. Put the car in the air and push on the tires to see if you get any movement. Change your links if that doesn't help move on.
No, the clunking was there before i changed control arms, but i started the process of elimination with those first because i had excessive tire wear. I pushed and pulled with a crowbar but didn't see any movement 130k on the clock
