This is what mine sounds like!!!!!!

 

Yes, yes! Only on bumpy roads! Please someone tell me you fixed this and it was NOT your suspension.

 

I am starting to have a noise issue with my rear right side also, a squeak and a bit of a thump. I got out of the car last night and pressed down on the right side of the hatch and noticed that it made the squeak sound, but the drivers side didn't. I rotated the spring loaded bumper on the right side and tried again, squeak was gone. Tomorrow I'll take it apart and clean and or lubricate the bumper assembly. Next is to go after the clunking. It seems that different fixes work for different people . The key I would believe to resolve this would be to trouble shoot correctly. Easier said than done, but just like any other trouble shooting, those who just throw part's at the problem are doing just that, not saying that it doesn't work sometimes, but to really get the answer you have to take it down to the engineering level of the problem. I will keep posting with anything I find.

 

Can you elaborate on this "spring loaded bumper" you're talking about here? You wouldn't be talking about the hatch spring that holds the trunk up, would you? Sorry, pretty n00b at these parts interpretations.

 

Same for this.... "stud"? Like, me for example? I'm a pretty good lookin dude you know.... LOL. jk. But you sound like you know what that clunking noise is, and I'd like to check it out.

 

I can hear a clicking sound on the rear, but I only hear it at a low speed such as parking lots, turning into driveways. I have no idea what it is please advice.....

 

Ok I'm not reading all 20 pages to see what you guys have and/or haven't tried but during my stint as a Nissan tech, I came across this noise more than once. Three times to be precise. Each of those 3 times, I changed the appropriate strut. 100% fixed and never came back. It took me FOREVER to figure out the first one but the noise is so distinguishable that it takes only hearing it once to know if it is or isn't. My roomate's Nismo 350z has the same problem...took it to my old work and just told them to change the R/R strut to save the tech from going through the painstaking process of pulling the interior and riding in the wheel well while someone else drives (what I ended up doing).

I won't say this will fix everyone's car because there is no way to know if the sounds being described are really the same but I hope this helps. Best of luck.

 

The strut is definitely a part of the problem. But the central issue is the thick bolt that run through at the bottom of the fork. Some of them begin to corrode a little bit and wobble around.

 

I think the noise is from the gas in the shock absorber going through the valve. Somehow, the gas migrates to a position where it can get to the valve if the shock doesn't get warmed up for a while.

The noise in mine goes away if I drive the car far enough to warm up the shock, and it won't make the noise for the next couple days after that. It'll come back if I don't drive the car very far at one time for a few days.

The noise in mine only happens when the wheel move down before coming up, as when I go over a groove in the pavement or a drop where new pavement ends. It doesn't make the noise if I hit a bump that causes the wheel to go up first.

I tried the bushing around the lower attach bolt and greasing the area where the upper end attaches to the body, but those things made no difference after the first couple days.

The noise will go away if I take the shock off the car, let it fully retract, and then reinstall it. I've never seen a gas-charged shock that gets shorter when you take it off the car, and I've never seen a shock that makes noise, so I think there's some causal relationship going on there.

 

bump.

this **** is driving me insane. I've gone through the thread and listened to the posted sound clips. I've taken everything out of the back, looked everywhere for loose clips or anything loose and found ****. It also doesnt seem like the struts are going bad. Could someone please take 30 seconds to listen to what my hatch sounds like.

The sounds start around 17 seconds until the end of the video. Basically its the clunking on the right and sometimes i get this random squeak sound. Might have to turn the sound up.

 

Does the rattling sound like a small washer moving around in a stud? I started getting this rattling noise when i installed stance true type coil. WIth that noise, it also gave high pitched squeeking noise. THey both are coming from RR..
I removed the coilover before to check out if anythings wrong, but everything looked fine.

 

^**** that's super close to the sound i think. I have noticed that the cover on the rear strut is a bit loose and squeaks, but I havent found out if the loud squeak is from there. Ill try and check soon

 

Yeah I'm having the same exact sounds as the videos. It sound like a bolt is hitting metal pretty hard all the time. I don't mind it, but it drives my girlfriend crazy. And it would be convenient to fix. I jacked up the car this weekend and looked at the shock itself (I'm running an OEM coilover setup) and everything was perfectly tight. Even the bolt at the bottom of shock. I replaced that with a thicker bolt from OEM because my Coilover hole was bigger.

 

Well I took the shocks out and put a spacer in the hole of the bottom of the strut "fork" and added padding to the top of the strut where it mounts to the body as outlined in this thread but I'm still getting the SAME FAWKING SOUND. It's driving me absolutely nuts. Only happens when it's cooler than about 60 degrees or so. !*$@#&%$#%^!

 

Drive the car with the shocks removed to see if the noise goes away.

If the noise is only on one side, switch them side-to-side to see if the noise follows the shock.

The noise in mine goes away if I drive the car for long enough to get the left rear shock warm. See post 391 above.

I'm convinced it's the shock itself. Maybe you could buy a new one (or borrow a known good one) to see if that cures the problem.

 

We're thinking the same thing. I removed the shocks a little earlier today and will drive it later after it cools down a bit. Hopefully it's just the shock, that'd be an easy fix.

 

I drove around with the struts out and I believe the sound was gone. There may have been a very faint sound still there but it was probably my imagination. I switched the left and right struts and reinstalled. The sound is back! But still only on the passenger side rear.

So switching the struts has done nothing. And I don't think it's the strut themselves because the sound only occurs on the passenger side even if I switch the struts.

 

Well guys I have a 350ZR that previously did not have this issue with stock suspension, I just put coils on and now have a metal clunking noise from the rear suspension area on the passenger side so its not the hatch in my case since there isnt one. I dont remember any gasket being on the top shock assembly so that maybe it but I also had issues tightening the bolt that goes through the lower shock to the suspension link. I will be replacing the bolt first and if thats not it I will be trying the gasket on the top.


Also another side note im running my coils as low as they will go so maybe im just going to have clunking period.

 

read this and looked at the bottom of my car and found that one of the hanger mount nuts had fallen off letting the mount rattle against the bolt.

 

Just checked this bolt on my car but no cigar. The sound has worsened lately and I've determined that it's actually coming from both the driver AND passenger sides. I'll try anything at this point...
