I am getting like issue but from the front. When I take off from a dead stop, I get a slight squeak, from a control arm maybe? I noticed while under the car that the boot for the control arm was flat, meaning it was not holding any lubrication, and noticed the lack of grease fittings. I was going to send it up to have it inspected while replacing the steering stabilizer, which is leaking, but thought I would try here first.
