I am throwing this out again for some comments.
I have a 91 EB. When the vehicle is COASTING in neutral or drive at speeds above 60 mph and no torque is applied to the drive line, I feel and hear a vibration from the floor. It sounds / feels like the vehicle is going over very small and close rumble strips in the road. When the vehicle is accelerating or decelerating, the vibration / sound is gone?
Rear end gears? U-joints? Drive shaft bearings in the transfer case? Drive shaft bearings in the rear end?
Any suggestions from others that have experienced this?
Doug
