I recently (120 miles ago) replace the accumulators on my '82 300TDT to smoothen out the bouncy ride, but it does not seem to have worked. The first ride was a little smoother, but then it went back to being bouncy (less than 5 miles). Also, the rear end of the car now sits up higher than it previously did, maybe 1.5 to 2.5 inches, enough so that the rear view mirror had to be adjusted.

Any insight into fixing the ride quality?
