I took the torque tube apart, removed the old seal and bushings to ensure everything was clean and free of burrs. I checked runnout of propeller shaft with a dial indicator and brought it to within .003" using heat. The design is press fit (no dowel pin), and the okie bushing was not spinning in the tube. I checked fit of bushing prior to assembly and lubed the heck out of it. The only thing left that I can think is that the torque is bent, and I can't see any way to accurately get that within specs with the thousandths of an inch that it is out. I've straightened many things with chains, an ibeam and a jack, but that method is a little severe when dealing with a few thousandths of an inch. I guess it's time for a new torque tube assembly.
