I have a 92 190E 2.3.

I get a clunking sound when i start the car and when in drive or reverse at idle there is a lot of vibration.

My best guess it that the motor and transmission mounts are bad.

There are 2 types of motor mounts for this engine - Hydraulic and solid.

My question - What is a hydraulic motor mount and are they better or worse than the solid-given my problem?

Thank you in advance
