What all parts did you use, and replace, when you lowered your vehicle?

 

Does the vibration go away if your turning your wheel?

i used a springtech monte spring. and kept all the factory things. and removed the bump stops completely. vibration does not go away when turning

I saw your PM aquase, sadly no I don't have a solution, but I advise you to take a look at my latest replies so you know what all I have figured out already.

Where do you feel the vibration? in the seat? in the steering wheel?

im pretty sure the vibration is coming from the axles.

are our trans and motor mounts like the 2nd gen gps???

You are correct. The vibration is most likly due to the combo of the weak old engine/trans mounts and the new lowering of the vehicle. There are five ways to fix this concern:

 

1) Replace both lower engine mounts (better if with solids from napa)

2) Custom Made axles

3) Lower the craddle a little with a spacer

4) un-lower the vehicle

5) Deal with the vibration

 

Way to make sure that it is a driveline vibration. Find a large crowned hill. Drive over the top on accel without the vehicle leaving the ground. You are just looking to get the suspension to extend. If the vibration changes, then it is the axles.
