IMO that would be the first thing I would try. Good Luck.
Well I took the 6 concrete block out last night, pushed down & lifted up on the rear of the car and it has dropped 1/2". I went ahead and set the rear tire's up on blocks, (put 3 blocks end to end giving me 4 feet to run back & forth on) with cardboard between the blocks and tire's so that the tire's could move, loosened all the lower control arm bushings. I drove back & fourth 6 times, got out of the car, pushed down on the rear of the car, got back in and did it over again then tightened the bushings. When I let the car down I drove it back & forth in the garage to get the wheels out of the bind from being lifted, then measured and it made no difference. I went ahead and put the blocks back in the rear of the car and I'm going to leave them in there for a few more day's.
