Ah... So not something I would have messed with necessarily. I changed to H-Sports lower control arms. If these things are designed to make this much noise, I'll be swapping them out hahaha.

the hsports have a rubber bushing and thus should not make noise. i have the ireland engineering arms which are solid heims... these make a butt load of noise. as do alta and others that use a solid metal heim.

my money would be on trailing arm bushing and or the top nut being loose. I might have missed a few posts in this thread. does it only do it on rebound or up stroke?

Well after a thorough investigation we think it is the exhaust heat shield (guess you WERE right Glen! ) rubbing on the control arms or other bits. We took the corner apart and everything was as it should be. Drew bent a piece of heat shield out of the way and the noise has changed. It was actually gone til the car settled down after being lifted up. Now this AM it's back in in full force but it's different. Not so much metal on metal clanging but squeaking and bumping. So since the car has settled I'll get under there and see what other adjustments I can make to the heat shield.

Glad its all working out.

If it makes you feel any better about forgetting to tighten ish down all the way here is a little story for ya.

I was doing the brakes on my wife's S and I left the caliper spring off the drivers side rear long enough to remount the wheel, lower that side, lift the other side and remove the pass. rear wheel. Spotted it on the floor when I pulled the passenger wheel out of my line of sight.

Just thought I'd drop a note. Part of my rear end issue proved to be a slightly loose rear sway bar endlink. Got that tightened up as well as shimmed up the bracket that holds the fuel tank. That was rattling a bit too. Now at least my car doesn't sound like the rear end is gonna fall out of it. Still rattles but not quite so bad.

Just an update... The rattling has come back with a vengeance. Been there for a couple weeks at least. As soon as I can get up with the tech that helped me out with it last time, I'll be back in the shop. It sounds worse now than it was.

Well since I posted last, I had someone look at it and we switched the right and left rear assemblies. Just moved the whole tower from one side to the other. The rattling moved with it, ruling out the control arms and definitely pinpointing the coil over as the issue. We had a couple more trouble shooting ideas but haven't had time to test anything out. The odd thing is it gets far less noticeable when it gets warm outside. The colder it is, the harsher it is. Drew actually suggested I call KW and see if this is a known issue or what I should try to do about it. I hear they have pretty good customer service and if worse come to worse I'll send the one coil back for repair or replacement. Just gotta make the time to do it. So that's where I'm at.

genius! i'm not sure i would have thought about that. good way to narrow it down to a coil vs assembly.

I dropped an e-mail to KW this AM. I'll let you guys know if/when I get a response. I couldn't find a phone# on the website. I didn't look really hard though.

Good call on swapping sides. At least now you know where you're headed with it. Rattles are annoying!
