I put my tocs and springs in the rear. When i hit bumps i hear this knock sound. I thought something was hitting my trunk from underneath. Anyways i check it out and found out that one of those bell looking things by the sway bar is closer to the trunk then the other. Since i am dropped i think that bell thing hits my trunk. That noise just pisses me off even on little bumps i get it. Any ideas guys? how to stop it.

do you have a S.T. rear sway bar? Do you have an after market exhaust? If so, most likely it is the rear sway bar hitting your exhaust. I have like a .5" clearance on mine and noticed that it is most likely why I hear that sound.

Like TPhelps said, turn up the music, you should only hear it when hitting larger bumps

Replace your exhaust hangers with smaller ones. Aaron's Greddy was banging on the lower crossmember, and the worn out hangers were to blame. They stretch too much and let the piping hit the crossmember every time he hit a bump.

Spent like $7 at the parts store and got 3 new, slightly smaller hangers, and the noise completely went away. I thought it would be the sway bar hitting, but I got under the car, shook the muffler, and sure enough, that was the problem.

DO NOT USE DUCT TAPE!!!

Only when going up an incline, or slowly accelerating.
