Rear end wobble and squeak
Hi- my 2006 CTTS has developed a squeak / creak when going over bumps at low speeds. There’s also a wobble at motorway speeds. Both appear to be coming from the rear passenger corner. The wobble gets worse around 70mph and then fades a bit.
The obvious candidate for the wobble is the wheels / tyres- but the garage said they are fine (although I don’t know how thoroughly they looked).
Are there any components that could be to blame for the wobble? Control arms, etc? (Again, I specifically asked the garage to check these, the anti-roll bars, etc. and was told they are fine.)
I have this feeling that the squeak and the wobble are connected...

Did they remove the wheels and put them on a balancing machine?? Would be IMPOSSIBLE for them to check visually otherwise.
Squeak will be a bushing, sometimes bushes appear OK but they're not, some of them you can't really see without undoing the joint, balljoints go loose but they normally knock, bushes squeak.
How many miles on the car?

Is it possible that old bushings could allow play in the wheel, resulting in wobbling? The car has 105k miles. Front control arm bushings done, but not the rear to my knowledge.

Yes, most definitely. Years ago on a BMW M3, I fitted Powerflex bushes and one of them fell apart and while driving straight, I had terrible wheel wobble, a vibration I felt through the car as the wishbone was just jiggling around.
What about your prop bearing, is that ok?
