Poly Lower Control Arm Bushings VS Rubber
Take this for whatever its worth.
I rebuilt my suspension over the last two weeks and researched this topic on here and other forums. This was my take:
Poly bushings squeak after X amount of time and the only real solution is get a silicone spray to lube the bushings every month or so.
However, look at your LCA, do you think you can effectively lube that bushing when its bolted up? If no(which was my conclusion), do you want to disassemble that LCA each month? Or can you live with squeaks?
