I have a 91 4x4 Ranger with the 2.9l. Auto trans/t-case.

Above 60mph I get a decent vibration, Nothing dangerous just makes me want to avoid the freeway. Tires are balanced and have no slipped belts or issues.

Below 60 the truck rides pretty smooth for what it is. But as you left off the gas (not completely off) there is a spot where it vibrates pretty bad. But if you get back on the gas or let off completely the vibration stops.

Any Ideas?

Check the Fan
Fan clutch going out can give that type of vibration.

I'd suggest looking for play in the rear drive line, particularly the drive shaft u-joints.
