I just had acouple of questions for you guys since you're so helpful and all. I have an 88 jeep wrangler soa lift. The springs are 1.5" lift the shackles are 1.25" lift with a cv style drive shaft. The jeep vibrates I think it is becuase I went too high and the rear shaft is vibrating. Do you think if I get the shaft balance the jeep will run smooth again or do you think I need those stock shackles put back on. My other question is someone wants to by it and drive it 100 miles away do you think he'll make it. I can drive as fast as I want with the vibration it runs smooth when I'm coasting not giving it gas but once I hit the gas it vibrates. please help

Did you put a wedge on your transmission to make sure the driveshaft still reached the rear dif.?

How much is it to reset the angle and do you think the jeep has good chance of driving for 2 hours straight.

With that vibration I wouldn't drive it 2 hours. You'll likely loose a u-joint on the way.

x2, if the pinion angle isn't right, don't drive it very far
