Signs of Bad Motor Mounts?

What are signs of Bad Motor Mounts? I had mine replaced about 8 months ago. I beleive they're okay. I notice a small popping noise once I accelerate in a turn.

sloppy shut-down. feels like the engine is loose when its powering down. some is normal. I replaced mine (super easy), and the whole car felt tighter accelerating and decelerating. you can usually take a look at the mounts to see if they are torn. replace them if they do.

Hi,
I got a 95 E300D with 105K miles. I believe the motour mounts are original. At engine shutdown, the car has a little shake. When I start it up in the morning. I can a minute rattle coming somewhere from the cabin. Could it be the motor mounts are causing extra vibration.

How are your guide rods? (look at the rubber bushings on the end)

This is a point on which I am not clear. If the mounts are not torn, are they good? Somewhere reading old threads I got the idea that some people were replacing mounts that looked good but did not perform properly.

Motor mounts for 603's are liquid filled, maybe gel, and the way I understand it, you must check the distance between the crossframe and the oil pan.

I think it 1-1/2" was OK, mine are down to about 7/8" since early fall and look fine but I have vibration now at the lowest rpm, but it does smooth out above 900 rpm. I plan to replace them in the spring. BB
