I have a 91 LS 2dr with almost 110K miles on it. I took my car into Midas to change the left front axle (cv joint broken) and asked him to check the rear suspension b/c I've been hearing this squeeking (metal-metal) noise coming from the rear - it's been driving me up the wall - he showed me the lower control arm bushings all torn up. Anybody have had problems with noise and worn out bushings? What am I looking at in re: to repairs and costs? What are some other causes of noises coming from the rear? Thanks in advance.
