While chasing a high speed driveline vibration(dead smooth below 98 mph with dramatically increasing resonance above that), I bought the tool to change the bushing in the car without disassembling the transmission. It works like a charm.
However, even with a brand new installed bushing and yoke, the clearance between the two parts is excessive on my stuff. A buddy of mine is making oversized bushings to reduce that clearance, but having the yolk plated and ground to a larger outside diameter is another option.
I've yet to do either so far, as I can't figure out how to measure the inside diameter of the installed bushing with the output shaft in the way.
