Lower control arm issue

When I rebuilt the LCAs for my Challenger I used poly bushings, and the original inner sleeve stayed on the pin, the poly bushings weren't "stepped". That's why you can buy 2 different types of pins, 1 turned down for rubber with the inner sleeve and the other full diameter the entire length for poly (or the even more solid nylon ones). The peices with poly bushings pushed together pretty easy, but I found they would also allow the LCAs to shift back and forth between the pin and the torsion bar while driving. For my last couple rebuilds I've used rubber for that reason. Adjustable strut rods helped keep everything in place as well.
