Tom, I do have the manual and followed the instructions but I am still having trouble. The bushings are threaded on the inside to screw on the shaft and have threads (more like ridges) on the outside to screw into the control arm. When I try to tighten the bushings with one person on each side it threads onto the shaft but doesn't thread into the control arm - it just wants to bend the arm. I'll try Tony and see if he has any advice.

Thank you for the responses.
