SLK320 Motor mounts
 

How can u tell they are bad? They have a plate over it so I cant see them. Also how hard are they to change out.

Are you getting vibrations in the car??

Have someone push the motor. If you can see cracks in the rubber, they're probably bad.

My car was in the shop for a month because of a main computer problem that caused a lot of cutting out. Since I have goten the car back it just dont feel the same. When I start the car cold and put it in reverse i feel a big viberation when backing up. At idle it does viberate a little in drive. There is no angle i can get to to see the full mount.

Ok confirmed that they are bad. Any one know where I can get some cheap? How hard are they to change. Indy wanted $300 to change them.
