Shakes a lot when i come to a stop and in gear. Shaking goes away when I shift to neutral. At times, the shaking seems to be more rough. It doesn't snake when it's parked. My car is a 2001 E320.
Motor mounts have been replaced twice- issue still present. A vehicle of this nature should NOT have this problem.
Noticed strong vibration at idle. mechanic determined motor mounts were bad; engine was resting on torsion bar. Repair was made and problem corrected.
I have a vibration when at idling with the car in gear. I replaced the transmission mount and it got better but the vibration was still there. Upon further investigation I found the motor mounts rubber was cracked which I believe to be the problem. I just ordered the parts today and hope this cures my problem.
I had a vibration under the drivers seat and under pedal. Also at a stop light steering wheel will vibrate. I made the mistake on buying a used motor mount at a junk yard. It worked for 2 weeks and then the vibration came back. I was afraid it could be the transmission. I bought both motor mounts new cost was 95 dlls each. Dealer wanted 175 dlls per each because their mercedes manufacturer. My mechanic charged me 100 dlls for labor. I returned the old one to the junk yard but I got credit back. It was only 40 dlls. Don't do my mistake buy them new. Now my car runs smooth and my headache is gone.
Vibration in the vehicle, especially noticeable during acceleration was traced to perished motor mounts. Replaced motor mounts resolved the issue.
I'm really hate this car because of the vibration caused by the engine which is effecting the whole body and the I tire room I didn't fix it yet I'm planing to go to the dealer and file for complaint for this problem
Notice a very bad vibration when first starting up in morning. Mechanic said caused by motor mounts beginning to fail. Plan to have them replaced at next oil change.
