1997 W140 S500 with self leveling suspension. I bought this in November and the suspension was very bouncy. I replaced the front shocks, which helped, then the accumulators for the self leveling rear suspension which cured the bouncing. The ride is now very good, except over harsh bumps I hear a clunking coming from the rear. My understanding is that replacing the upper shock mounts will probably cure the problem.

How hard is this job, and how long should it take for a fairly good DIYER? Also, how do get access to them? It has finally turned really cold, so while I can stand a couple of hours under the car, longer than that is too much for me.

Any advice would be greatly appreciated. Thanks.
