replacement suspension bushing advice - poly vs rubber

Poly will not squeak if properly lubricated. I use the cheapest poly bushings you can buy and I’ve run them for tens of thousands of miles with no issues at all on a couple different cars now. Grease the heck out of them on install, and use greasable LCA pivot pins so you can grease them periodically. That’s all you have to do. They just require different installation and upkeep than rubber.

When I pulled the poly bushings out of my Duster and replaced them with Bergman Autocraft Delrin LCA bushings, the poly looked brand new still. That’s another option too, Peter Bergman, member @GMachineDartGT, sells Delrin LCA bushings. No grease needed, and even less flex and give than poly. But again, the pin fit has to be right and adjustable strut rods need to be used.

But it depends on application. If this is just a cruiser and you want to keep the suspension components stock, stick with rubber, because you probably won’t be happy with the poly bushings and stock components.
