I have a squeaking /chirping sound coming from what seems like the drivers side, but definitely the rear of my car. It only does it when you are moving very slow over easy bumps (weirdly not on big bumps) and seems a bit more pronouced when turning really slow as you creep along. I had the exhaust off of it twice when I did my bolt ons recently. Used all new rubber hangers and lubed them all good. I think that its unrelated to that and the noise is coming from somewhere in the rear suspension, but cannot pinpoint it. Any ideas?
