Question
I have 1994 Mercedes SL600 the car bounces a lot  in back I have been told that the self leveling Accumulator are bad so can any one verify that and tell how to replace them .
thank you

Answer
long answer thye way to check is to push on back end of course if it is bounces alot its your accumulator check for leaks around by it. Then check the accumulator lever and verify fluid is going to the accumulator obviously it is a hydraulic suspension system . from there you will have to email me again
