Vibration!

Propshaft bearings perhaps? Does the vibration go when you just ease off the throttle and take the weight off the drivetrain.

Turns out it was the rear Propshaft CV joint it collapsed and damaged the joint housing so have to get the lot replaced. First major breakedge on a 20yr old truck, not bad at all.
