Polyurethane bushing squeak

Switch it to the original rubber and don't listen to anyone promoting the use of poly bushings or any of the aftermarket junk some of these members are using for bandaids for their original control arm suspension cars. Unless you are going to go the whole route of replacing the complete suspension with aftermarket parts the poly bushings are a waist of money.

I think I’ve narrowed it down to upper control arm bushings.

hmm... interesting because YOU previously stated that you install poly in the uppers.

so are you going to post the usual same pictures of the "restored" K members? or the blurry one of engines sitting on K members? or that sweet one of you in the 80's rockin' the fast cash mustache?

all that aside, i'd love to see that video of LCA defection & movement with a poly bushing that you've been promising. or lemme guess you haven't had your son build that jig yet?
