I havent tried to get above the zone, so I cant tell you if it goes away. Its a vibration for sure and pretty high frequency. It doesnt feel like the steering wheel. It feels like the whole car, so I would say closer to by butt. The display I have on the dash gets unreadable when you hit the vibration because of the high vibration frequency moving faster than the eye can follow.

Highway gears, 3.08s. Its the same driveshaft so I wouldnt think it would be the issue. Though it was probably already a bit too short and now with the car lowered its even more so. I need to have a 1350 end put on it and have it shortened by 3/8ths.

Also for clarity when I say the shake is better than it was, I meant that lowering the rear with the 2* correction blocks helped. The alignment had no effect.
