Hey everyone,

I'm planning on ordering a replacement motor mount tomorrow for my '95 E420 (86K on the clock) and have done the following diagnostics:

The car has a low rumble at a stop with the transmission in Drive. Rumble increases (is more constant) with the AC compressor running. When transmission is shifted to Neutral the rumble goes away completely. When shifted to Reverse I'm unable to notice any rumble.

This leads me to think that it's just the passenger motor mount (visibly is collapsed) and not necessarily both mounts. At $110 a pop it would be nice to resolve the issue with a single replacement. (not to mention the fact that it would be a little bit easier to replace than the driver's side mount)

Just wanted to get a little feedback prior to ordering the part.

Thanks in advance!!
