Did put the car up on the lift on July 26 as planed. Removed the next to the shortest leaf on both rear springs. Drove car around town seemed to help. Didn't take the car out on the open road untill yesterday, drove about 100 miles. What a difference the car road so much better no hard thumps like before. Thanks everyone who contributed to this thread. Look for my next thread about my steering. Untill then good motoring.
