My 87 300E has 320K miles. A recent MB club mag (Star) told how to change the engine mounts in its driveway mechanic article. I have not changed engine or trans mounts for 7 years or 135K miles. How do I tell if they are bad? Should I change them anyway? There is a tech session next Sat.
Thanks

The lower portion of the motor mount is BELL shaped. You should replace the mount when there is less than 13 mm clearance between that portion of the mount & the crossmember the the mount sits on.

My 300E has 280,000 Km on it and I've having the mounts done soon - they need to be replaced as diagnosed by my tech. I had complained to him that my idle seemed rougher than usual with slight tremors through the chassis. Turned out the mounts are toast. Not an expensive job.

Are the motor mount measurements similiar for 95 S420 car?

Thanks for any info you are sure of.

Luck to you, DanielW
