I searched and think its my New Poly Trans mount (Didn't know to remove the plate and Nipples, DOH!) But I also put in a Hiem Joint/Hiem Joint Panhard Bar in the rear. The Car doesn't really vibrate till around 35 mph and a cruise down the highway SUCKS! Its like vi-BRA-tion-SUC-ks-MAJ-or-BAL-ls when I deaccelerate from 50 mph to 40 mph. Is it due to the new mount that maybe I can feel a driveshaft out of balance? Could the Panhard Bar be not the problem at all?

If its my mount, then I will cut of the Nipples today.

A good quality rod ended PHB will be virtually silent. It sounds like the transmission mount is your issue (I had the same issue when I puta poly mount in my 3rd gen years ago).

your tranny mount is fine. i left the plate and didnt grind the nubbies either. takes a couple hundred of miles to let the mount "settle" in.

I just changed mine. I was wondering how much vibration goes away? Right now I feel much more vibration/chatter from the original one. It also doesn't feel as powerful. Any help??
