Next to the center rubber differiential mount this is the number 2 reason for rear end sag. It is also a primary cause of rear end wander and adverse tire wear. For optimum performance and handling rubber suspension parts on these old Benz must replaced after 18 - 20 years.
PLEASE CAREFULLY NOTE MODELS LISTED ABOVE: These do not work on the 1975 to 1976 300D. That is now a dealer only part so you will need to contact a Mercedes dealer.
Rear subframe mounts can be replaced without removing the entire rear end if you do one side at a time. There are a few tricks to make the job go smoothly. Pictorial instructions are included. We recommend you replace the CENTER DIFFERENTIAL MOUNT and the SWAY BAR drag links at the same time.
Here are pictures of the location of these mounts and what a bad mount looks like when removed.
