My bronco has a vibration at around 35 mph when there is a low amount of torque on the drive train. Diff. is good, tires are balanced and the vibe goes away as soon as you stomp the gas or let off of it. Anyone have any ideas.

Check your drive shaft u-joints. It just so happens mine did this about 2 weeks ago and it was the u-joint on the rear ds on the pinion. Mine was vibrating at 30-35 mph.

vibration at 35 mph (u joints)

I took my drive shaft off and inspected the u joints and seem to be okay. I am going to reinspect them and a friend told me to try rotate the drive shaft 180 degrees and see if that helps.

Look at them very closely(with a flashlight)--paying attention to the caps.

with the driveshaft on the truck grab it and shake it. You should have zero movement. If it even moves a little one or all of the u joints are bad.
