I recently had my springs installed by another member here. He noticed that I had these plastic/rubber blocks that attach to my front springs kind of like a spacer. We put them on the new springs. Now when ever I am turning it sounds like something is rubbing, but I have checked and theere is plenty of clearance around the tires. I believe that this block is causing the rubbing noise when I turn. The guy who did the install said he did not have those spacers on his '02. Does anyone know what they are, if I need them, and if it would make sense for hem to be the cause of the rubbing noise?
