New motor mounts = new vibration.

So im trying to isolate a drive line vibration so after reading many many posts in the old threads I figure I will start with the less expensive things to try to get to the bottom of my vibration issue. Well I installed new motor and trans mounts last weekend and now I have ANOTHER vibration when at idle in gear like when I pull up to a stop sign. When at a stop sign in gear when the rpm's drop to an idle the vibration starts, kinda like a rumble that was not there before. If I put it in park or netural is lessens a lot it mainly when in gear. My other vibration issue is at highway speeds.

Do the motor mounts need to break in or something? Could I have installed them incorrectly? Do they possibly need adjustment?

It's possible but not probable. Unless you have a big dent in the bottom of the pan from jacking I doubt you did any damage. I would suggest you BLOCK the wheels and have some one sit in the van with it in gear and their foot on the brake. Be very careful and listen for the noise. From the outside it should be fairly easy to find the noise.
Please don't run yourself over!! :dunce:
