So I installed Bilstein coilovers and now my rear suspension is squeaking (some minor squeaking in the front). I know it's related to bushings. During the install i did't have to remove any bolts for control arms etc., so didn't have to re-torque any bolts. I tried spraying all bushings with silicone lube, but it still squeaks! Would it be the swaybar bushing squeaking. It's hard to pinpoint. Has anybody else had this issue?
