It is often mistakenly thought that rear vehicle sag is caused by bad shocks or weak springs. Shocks are never the problem and only rarely are coil springs the culprit. With a Mercedes suspension that uses numerous rubber parts, it is the deterioration and deformation of the rubber mounts and bushings that cause the subframe to twist and collapse. This is true on sedans, coupes, and the TD wagons as well. Just replacing expensive struts and accumulators on the SLS (self leveling suspension) in most cases will not solve a sagging rear and trying to fix the problem by adjusting the leveling valve only give unacceptable ride and handling characteristics.
Fix it right by replacing the parts that really wear out. Even if you think they look good that is no assurance they are. Subframe mounts usually collapse on the inside where you can not see the damage. Differential mounts just slowly sag over time. Worn trailing arm bushings can cause uneven tire wear and clunking in the rear end. Replacing the spring shim can raise the rear end close to an inch. If you are going to have the parts installed professionally, a Mercedes specialist is not required. A good suspension shop can do this work usually at less cost.
Fits all 240D 300D 300TD 300CD 280E and 280CE from 1977 to 1985. This kit includes the following parts:
- Rear Differential Rubber Mount
- Rear Subframe Rubber Mount Kit
- Trailing Arm Rubber Bushing Set (4)
- Rear Stabilizer Plastic Links (2)

Note: Replacement of of the trailing arm bushings and subframe mounts will require the removal of the entire rear subframe assembly. This is best done on a car lift with the aid of a transmission jack and a strong rolling table or bench.
