Lately the car just isn't as smooth as it used to be. I can feel vibration from the engine at idle in park or drive. I also know our Motor Mounts tend to fail. Could this be the cause? If so is there anything I can look for to confirm this?

 

yeah, i just had mine replaced at 25k miles on my 01' cls. its under warranty.

 

I'm out of warranty at 55,000 miles..go figure

 

that sucks. but you are still probably going to have to replace them.

 

were yours doing the same thing or how did you know they were bad. Is there anything I can do to confirm its motor mounts? Its not real bad just not near as smooth. I used to not be able to feel the engine idle much at all.
