Finally picked up the beast.
 

I got her last Friday and drove home from LA. Ran into some issues, but I was able to make it.
Dealership did brakes, battery and checked everything else. They also rebalanced the wheels.
I have a huge vibration problem. It is not the usual steering wheel shimmy that comes from the bushings. I feel the vibration in my seat and on the gas pedal. It usually happens between 65-75mph. Here is the picture of the beast. Thanks

Looks terrific enjoy your new baby, she looks lowered lol

I think it was on the lowest setting. Thanks

Please update us on the seat vibration. Rear wheel balance? Warped rotors? Balljoint? Some things to look at. Enjoy her

ow wow, she does look lowered? nice..

Several weeks ago I had the vibrations issue. Not only my steering wheel but also the pssenger seat was vibrating. Long story shor I took it into the Dealer and was told that my rear differetial was gone plus damage to the right rear axle. Thank God it is still under warranty or else that would have been a very expensive job. Hope that is not your issue.

Wow, how many miles on your x and did they tell you possible causes of the rear diff failing?

I just bought all new tires (proxes stII). Goin into the stealership this Friday for all vibration issues. I will definitely update you guys.

possible causes? 4.8 motor that has been bagged....
