As usual I have to rebuild the suspension on yet another one of my cars. Did the front on my first 300D, did the front and some of the rear on Pancakes the 240D, and now I need to do at least the rear suspension on the '87 300D

I recently noticed a loud thudding sound under heavy breaking coming from what I am guessing is the rear.





This is the left rear control/camber arms. I am guessing the top image, the severely destroyed bushing is the cause of the noise. The second image has a piece that should be replaced as well.



Someone mentioned checking out the differential mounts. Yep, need to be replaced. I also need to pull the diff cover off and re seal it since its a little bit wet under it.

I think the subframe bushings are ok for now, some small cracks. The flex discs look good as well, no visible cracks.

Lemforder control arms are about $52 each, very pricey. I've used Febi parts before and had no issues with them. There is also, listed elsewhere a complete kit to replace all of these camber/control arms made by Meyle for around $236 with new mounting hardware.

Also there is a squeaking sound while turning or backing up at low speed, I am guessing that is the bushing that the is on the wheel hub/carrier.

One of the camber arms has subnotes that mention a sleeve and bolt kit but the complete kit by meyle comes with all of the hardware. Is it safe to assume that I do not need the sleeves then since I am using all new hardware matched to the new parts?

This thread shows the job, its clearly very very involved if I want to swap out subframes and make it pretty. I think I will just replace the one arm that looks bad and the diff mounts and go from there.

Replacing the diff mounts without dropping the subframe is a PITA. Diff has to come out completely from very tight quarters. Don't forget the diff forward bushings.

Awesome, maybe getting another subframe wouldn't hurt.

Found the section for R&R'ing the diff mounts. there are two different sets of instructions, both have different types of subframes and only the second one shows an image/drawing of the front diff mounts (rubber washer like mounts). The second set is for model 124.034/124.036.

The two diagrams for the differential mounts show two different methods, the second method, which is the only one that shows the front dif mounts has the diff still attached to the transaxels and is just lowered.

.034 (E420) and .036 (E500) are the V8 models which are different.
