Help!!!!!

I had an issue once before with considerable vibration on a Jeep Cherokee. We found the rear axle to be welded incorrectly at factory.

See if your axle might be bent or welded incorrectly from factory, (best way to verify this is to measure distance from edge of tires (tire tread) to body of H2 on both Driver & Passenger side.

You may also wish to check and see if one of the inner axles may be wearing. To check this, stand behind H2 and visually check if any of the tires sticks out further than the other or you can measure the distance from the body to the edge of the tire.

Hope this helps..

Had that happen on a car once, above 35 it would vibrate the **** out of the car. It was a busted U-joint.

When I accelerate past 40MPH my whole truck starts to vibrate. Anyone have any ideas what this could be? I think it's the transmission, but I'm not sure.
