I will only order from the store, never online. That has work well. I stopped ordering online from them after my card number was compromised by an employee and they charged over $5K in computer's. My bank was really good and alerted me before the charge was approved, but still.

Did you try to run without the front drive shaft and see if the vibration is still there, or just with the rear removed ? Did it vibrate with the stock tires and wheels after the lift? You say you tried your buddy's 37's and it was worse. Do you still have the stock set to try? Pinion angle...
