Good points Les, thank you. About 4000 miles ago I put in a new clutch. I had the flywheel refaced at an automotive machine shop. New pilot bushing too. If I am correct the flywheel can only go on one way due to the bolt pattern.
Three years ago I put in an Okie Assembly in the torque tube. I bolted up the u-joint as it was, not thinking about having it 90 degrees to the other as there is no other. The bushing I pulled from the torque tube was badly worn and almost oval shape.
This problem was there before I changed tires and I have checked the trueness but didn't use a dial indicator. It was a yardstick mounted on a stand. It did show me that one of my previous was really out of round.
Anyway I am still thinking wheels or axle, even though the wheels seem true. I will have someone drive it while I follow or have someone take a video while I drive it.
As to the ride, it is for the most part probably one of the smoothest riding AD trucks around. People who ride in it cannot get over it. Other ones I have ridden in are not as nice BUT there is that mysterious little oscillation that has been the subject of this thread.
