For all non-turbo 300D 300CD 300TD models 1977 to 1981 includes transmission mount

Have you noticed your Mercedes diesel sedan is recently shaking more at idle. Maybe you are noticing new vibrations that were not there before. You may have also noticed the engine makes some clunking noise when you shut it off. When was the last time your rubber motor mounts were changed. Diesels are especially hard on rubber mounts because of the excessive vibrations associated with the type of engine. If they have not been changed in the last 8 years then they most likely should be. Watch the videos below as Kent will demonstrate bad motors and will share some installation tips with you.

Removing the front rubber engine mounts requires getting under the car and going up inside a hole in the subframe to remove the main bolt. And it can be a bear! I don't know who they hired to tighten these at the factory, but he must have been a brute.
