DRIVELINE ?????'S

So I replaced my motor mounts and tranny mount....the car shakes like crazy. Thought it might be from a mis-aligned driveline. But it's not. I took the car in and all the angles are correct. So by just replacing the mounts all around, why would the car do this?? It drove completely fine before I changed the mounts (they are poly by the way) and it's more than the normal vibration from a stronger mount. The end of the driveline (where it connects to the rear-end, u-joint) was actually hitting the bottom of the car causing a fresh metal scratch/mark....I'M SO LOST, PLEASE HELP!

Vibration at idle? Cruising? Revving it in neutral?

so if the angles are correct, why is the rear joint hitting something? You have a wrong mount installed somewhere.

RE: DRIVELINE ?????'S

Yep, I think something is wrong with your tranny mount. You should have felt, or at least heard, it hitting the floorpan. There is no way your angles are correct if the driveshaft is hitting the floor.
