The car is an 87' GL 4WD. It has like 230,000 miles, however the engine and tranny have been changed like 10,000 miles ago. My frame is in perfect condition when i gaze under the car. No rust. I do not have noise from the back end that I am aware of. If you could explain to me exactly where the bushing should be i can make an accurate diagnosis of whats going on back there. thank a lot for you help. you helped more than my mechanic friend
