Polyuethane bushings has no positive lock on pivot shafts

As I turn the nut the shaft just spins inside the bushing, there is nothing to hold on to, and I am a long way from making contact with the k member.

I had the same issue when I installed my poly bushings. I was able to hold the collar with a thin jawed vise grip to stop the shaft from turning. Once you get it snugged up you can remove the vise grip for the final torque. Worked for me on two different vehicles.

Well, I tried the regular nut and it seemed to work, but then kept spinning. Went with the narrow vice grips on the further to the front and SUCCESS!!! Thanks people!! Still have the other side to assemble. Can’t make the same mistake twice?!?

If the polys were firmly attached as the stockers are you could probably do away with torsion bars altogether simply because the poly is so much stiffer than rubber.

WTF?
