Motor and transmission mounts
Hi guys,
First post. I bought a2006 SL55 and I see that the mounts were replaced at 50k miles. I now have 100k. Is this something that needs to be changed again or just the one time?
Thank you.

As needed. Depends on driving style and how often is the car driven. Mine is around 38k miles, but I've replaced the engine ones already. They have fluid inside the rubber mounts, and as soon as they worn out - all the fluid is gone and they need replaced immediately.

You can test the motor mounts by opening the hood, start the car, step on the brake, put it drive, and step on the gas. Do the same in reverse.
If the motor moves a lot, you need motor mounts.
Replace the trans mount at the same time as they last about the same as the motor mounts.

Thank you for the advice.
