[QB] The only thing I am not sure about is the Yoke on the rear end. How do I check it with a dial indicator? Shoud I put it on the yoke or driveshaft?
I'd see if you can jack the rear up (on stands of course) and mount the dial indicator to the rear end housing or to a very sturdy stand that will place the tip on the shaft of the yoke. You can rotate the tire slowly to see if the yoke is true, or if it has been bent.
A bent yoke would certainly make a bad vibration.
Just for grins I'll add this quick note (it may or may not apply):
I had a '74 Porsche 911 that had such a severe vibration in the front end at 65-90MPH that I had to hold the wheel with both hands. I balanced the wheels, checked for warped rotors, loose parts, etc. for weeks before I figured it out.
The locking lugnuts were so much heavier than the other factory lugs, that they created an imbalance undetectable at moderate speed. I had 2-3 diferent mechanics test drive the car and none of them could figure it out. As soon as I replaced them with the lightweight alloy lugs, the problem disappeared completely.
