Suspension Guru's
I need your help guys. I've had this rattle coming from the rear suspension of my DC4 integra for a while and everything I do doesn't seem to fix it. It sounds like a nut or bolt in a tin can rattling around when the suspension travels quickly. I have koni yellows and ground controls with the ground control top hats. Originally I thought it could have been the spring rattling when the suspension comes unloaded, so I removed everything on the rear, and adjusted the perch on the shock to its highest point so that the spring has a little compression at full droop and the rattle is still there, so now I'm confident it's not the spring rattling. I wasn't sure if it was the sway bar bushings, so I removed the sway bar. still rattling. I've recently replaced the lca's and installed a ASR brace, still there. The trailing arm bushings look fine. Everything with the shocks/springs looked fine when I removed them but I don't have a damn clue where this rattle is coming from. Its only noticeable when the window(s) are down, and seems like it's rattling on both side. I did notice that when I installed the new lca's that the noise did go away for a bit probably when the bushings were still stiff, but I can't figure out what it is. Any help would be appreciated guys. Thanks

 

Anyone have any ideas?
