I understand that, (I round tracked for 10 years in a leaf spring car).
My concern was if the tube itself slid in and out, or if the rear u-joint yoke inside took care of that movement. I could not see how the yoke could if the tube was fixed solid. Tim says the tube moves, although I think very little, in and out of the ball housing. That makes sense. I mis-stated what I said earlier. Logic tells me the TUBE would have to slide, not the yoke, to accommodate the forward and reverse of the rear end during acceleration and slowing. Same concept as the front yoke does at the transmission on an open driveshaft.
The retaining nut, with the two metal washers and the cork gasket between them, needs to be snug enough to seal, but not so tight it puts the tube in a bind. Sound correct?
