metalllic clunk sound when going over small bumps
hello my350z i own a 2008 350z and had a question about the sound im hearing. its been rather cold recently (30 degrees and below ) and i have recently been hearing a metallic clunk sound going over bumps or even really small bumps coming from the left rear of my car. everything seems to be working but its bothering me. I have also just a couple weeks ago had axle back straight pipe exhuast put on ( dont worry only temp. till tax return time ) i havent had the time to get outside and check since im working full time and since the weather has been so cold but any ideas? I apologize if this has been answered or if this is in the wrong location. Thank you
Jordan.
P.S. the car is lowered nothing extreme maybe .5" at most. actually whats stock height anyways?
thanks again

thank you for the response. its at 48k miles and i belive it was either aftermarket cups or cup mod was done? does that sound like an actual thing? my skills with cars only goes into electronics and wiring so i apologize with my terminology. but im pretty sure the rest of the suspension set up is stock. just to throw it out there i did notice my rear wheel fenders are rolled already as well. ( just to give a better estimation on my height ) if pictures are needed i can take them but it would have to wait till i leave work =(

What appears to be a permanent fix is putting thin discs of teflon or ultra-high-molecular-weight polyethylene between the contact surfaces. I did that to mine about six months ago, and haven't heard a peep since.
I happened to have some of the material on hand, so I made them myself.

Thank you guys for the ideas. everything was fine till about a day or two after the axle back straight pipes but ill check the sway bars. so far that seems like it could be the issue. performance wise im not feeling or seeing any difference, just the noise. when i get home ill take a picture of the area the best i can see if you guys can narrow it down. i have another idea of what it could be that ill point out in the picture as well. having fenders rolled was a very happy surprise i must say haha. after i solve this im going to dive into the word of spacers, offset, tire size, and wheel sizes >.< but thats for a different day...
p.s. axle back sounds better then i thought but my uncle, ( NH car mechanic ) when he heard it asked if i wanted a gift card to a muffler shop for christmas so i guess its a little too loud..... thanks again

no arvin89 sorry for my terminology when I purchased the car they mentioned it was slightly lowered. I asked with what method was it lowered and they replied with the suspension cups were aftermarket. frankly I dont really understand completely what it means but the car sits nicely

Update!
ok so after inspecting more closely I seen that I have aftermarket suspension stupid me for not looking closer and taking their word anyways the pictures show the brand of them, they seem to be stance brand
http://www.stancecoiloversuperstore....lus--coilovers
I dont know what level they are but im going to say the cheapest they sell to be safe about it. pictures included! dirty car is dirty.....
if you guys know what ones these are id appreciate the help! also I guess this means I can go lower? pretty excited to be honest I havent looked up any reviews yet but hey I thought it was stock with a weird cheap mod that nobody heard.
Also the clunk is very minimal now

With Stance you can go just about as low as anyone could want. It's a lot easier with stance too seeing you lower it via the coil body and not the spring assembly so it doesn't effect spring preload. It's just a matter of disconnecting the shock body(?) and the swaybar endlinks. You'll need to purchase one of their lowering keys (not sure of the terminalogy) to help you loosen and tighten it. You can also adjust the dampening, but it looks like the top **** has broke off from your pictures.
Edit: maybe the **** isn't broken off. Might just appear that way in the pic.

I have the exact same sound. Same setup with true coilovers (stance). Just happened recently. The coilovers I installed about 6 months ago with no issues (sound wise) till now. If anyone might know what it can be please advice. I'm going to look at it in detail soon.

well to be frank, STANCE and any other coilover setup is going to produce noise.period. They aren't made to be comfy daily driven products. But to answer your question, yes you can go very low with this setup....
