2001 Jeep Wrangler vibration

Would you describe the nature of accident and what was repaired/replaced. does vibration persist above 35?any shifting problems? is vibration felt in seat/floorboard or is dash shacking? is a roar type noise associated ?

The jeep was being toted and the tote vehicle had a collusion with another vehicle which caused it to spin around and flip over, the jeep then spun around and slamed into the tote vehicle and broke off the rear wheel and axle. The axle has been replaced and all parts from the differential to trans has been replaced. Yes the vibration persists above 35, and no shifting problems exist, the vibration is felt on the shift lever, and yes, a roar noise is associated. Again the vibration stops when the cluch is shoved in. HELP!

Was drive shaft checked to ,be true? U-jionts inspected?

Please read my question carefully, everything was replaced from the differential gears and ring-gear and pinion, drive shaft and u-joints so now whats left? Remember I said when the clutch is shoved in at 35 mph plus the vibration stops. I know its not going to easy to pin-point, like I said five mechanics can not figure it out. Help Thanks

2WD or 4WD? has vehicle been run on a lift or jack stands and duplicated vibration. Problem ia associated with torque not RPM so driveshaft is generally it was differential alignment and drive shaft angle checked. A hit hard enough to break an axle could have moved diff and /or bent frame. if trans is placed in neutral at speed to have vibration and coasting does it go away?

It is a 4wd. On a lift it does the same thing. I tried it in neutral at 35 and over and it does the same as when the clutch is shoved in no vibration. I have measured for out of alignment also no problem. Okay,open for more suggestions. Thanks.

so what happened?
