'93 190E 2.6 rear end

Does this car have a differential mount? Something is making a thud back there when moving off after shifting out of reverse and into drive first thing in the morning.

I believe it has "differential bushings" where the diff is suspended from the suspension. Its not quite the same setup as on the W123's.....

No! There are no differential bushings between the rear subframe and the differential on the 201 chassis. The differential is mounted with four bolts passing thru the subframe and threading into the differential's rear cover. There is also a single bolt vertically oriented at the differential's front which threads into a nut above the subframe at that area.

The most likely problem is one of more of the rear multi-link suspension elements; there are four separate links and the control arm with bushings at its inner and outer ends. The usual suspect or at least the first usual suspect to fail is the "thrust arm".

Replacement links will require an updated bolt/washer/nut kit as well.

It is not likely but the last potential problem could be the rear subframe mounts, but on these 201 cars and the 124 chassis cars these subframe mounts are long lived. Good luck!

I'm probably one of the few that had a subframe mount go out on my '93 190E that I purchased new. The right rear front one went out and it made a very weird sound and clunking noise when taking off and accelerating.
My wife came home from work one day and told me about the problem. I had her take off while I looked at the right rear wheel and I could see movement. I jacked up the car and looked at the bushing....it was cracked and had sepertated.
I replaced it myself and no problems since.
