W124 rear suspension

My aging 1989 W124 is starting to show signs of a tired rear suspension. Sideway movements, unstable in curves, etc.
What are the most likely worn parts I need to get at.

As you can see from the diagram, there are bits on both ends of 4 links plus the CA bushings that can wear out.


I have yet to dig into the rear suspension, so I'll let others nominate the components that are most likely to fail.

Seeing that your car is 10-years old, I would REPLACE *all* links and subframe bushings including the differential/subframe bushings, even if they look good, because they are too hard by now.

I did this and everything is tight as a drum.

In order, I would do all links, subframe, then differential bushings.

The torque rod is the usual culprit, I need to check my 300D and determine which one is bad (probably both....). Tie rod bushing also makes the rear steer badly when it goes out.

Needless to say, if one is bad, the others probably aren't too far behind.

Torque and thrust arms are the first to cause problems, they are parts 10 & 11 in the diagram. However, after time the rest of the rubber does rot and disintegrate. Figure $800-1100 for a shop to replace the rear rubber complete (excluding the subframe mounts). The rear diff bushings and the support joints (bottom of the wheel carrier) are the hardest part of the job.
