Replacing the motor and transmission mounts on my 87 SDL helped the vibration at idle immensely. I was timid about jacking up the engine at the oil pan to get enough clearance to slide in the new engine mounts so I pulled out the Harbor Freight foldable shop crane. In the past, Marshall has recommended using the Mercedes Parts for mounts as the aftermarket ones don't last as long. I did not know better at the time and used the cheap ones. They are working fine for now. Next time I'll use the good ones.
