When I hit 72MPH the rear passenger wheel shakes. I have balanced it twice, and checked the runout. It is fine. However, in inspecting the area you can see the rear bushing is vibrating, as the bushing is polishing the arm where the bushing connects. I assume the bushing is worn and there is not enough support there, so I'd llike to change it. How do I?
First change the wheel/tire with the spare or another wheel tire to check for any change in shake.If the shake is in the seat it is usually in the rear,if it's in the steering wheel,then the front.
If the wheels are balanced all bushing could be loose and it will still be a smooth "no shake" ride.
Don't forget if brake discs and brake drums are out of balance no amount of tire balancing will correct a shake.
Also there is static and dynamic wheel balancing machines.You always want a motorized "dynamic" wheel balance done.

Have you checked the u-joint yet? i had what sounds like a similar problem to yours and thats what took care of it for me...

I've seen some light trucks of the same era have worn bushings on the frame. You might want to check with Chevy dealer for details... there may have been a recall.

have the rotors machined, shaking when braking is an indication of a warped rotor or drum, even though it may look ok, the rotor can still be warped, it would be a good idea to have the rotors/drums machined and new pads installed if the old ones are 4-5/32'nds or lower. that should take care of your shaking when braking issue
