Clunk - left rear 190e 2.6 uni-jnt or xmsn
1994 190E 2.6 120k miles
Back up a short distance slowly then shift into drive and slowly accellerate...clunk. Sounds like the left rear takes a half turn before engages. Could be in middle of car but sounds like drivers side. Occasionally get the noise when going into reverse. Drives/shifts/sounds fine when warm but still has the clunk. Slow shifts when cold. Clunk is new and scarry. Is the problem likely to be: 1) Universal which needs replacing 2) Bad differential? 3) Drive line problem? 4) Transmission? I'm unfamiliar with the structure of a independant rear axel but seem to remember a front wheel car doing this once when the universal joint needed replacement.

It could be almost anything in the drivetrain beginning with the front flex coupling, which is the number one suspect. These are literally a "maintenance item" and will likely be cracked and loose by 60K miles.
You need to get the car up in the air and do a thorough inspection. Wiggle every joint/coupling/component and look for looseness. Duke |

Also check the differential mounts.

Did you find the problem?
I do have the same problem with your same description on my 93 190e 2.6L. Please keep us updated. I haven't looked closely at mine, but I am guessing it's one of the CV joints. Outer one (closer to the wheel).
Thanks, Meza
