Vibration in my 1991 MB e300


Asked by Nov 03, 2014 at 10:41 PM about the 1991 Mercedes-Benz 300-Class 4 Dr 300E 2.6 Sedan

Question type: Maintenance & Repair

I have a 1991 mercedes Benz e300 6 cylinder gas with 70,000 miles. I have a problem
that we can't seem to correct. When the car is stopped and it in drive it vibrates. I didn't
mind at first as the vibration sometime messages my aching back, but Id like to fix it. No
one seems to know what causes this. It only happens in gear. If I drop it to neutral the
vibrations stopped. Not motor mounts, plugs, wires, can anyone help. Contact me at all answers appreciated. Joe

Coil pack is good. Was checked, but idle control was not. I'll have that checked. Thanks. Joe

Check the rubber rings where the prop shaft connects to the gearbox and differential. Also, there's a bearing in the centre of the prop shaft where the 2 halves join.
