cracking/popping noise in rear seat/trunk
#31
I'm really leaning toward the rear suspension! Since the noise have return and it's worse than before. I try all the tricks... seat belts, stuffing all suspicious areas, checking for anything that might be loose, etc. Oh well, I'm not changing suspension unless its a must. If and when I have to change suspension.. will update.. lol
Please updates if anyone did something!!! Even if it didn't work. It would save some of us a few steps.
Good luck folks!!

Have the same thing going on. My next step is replacing my end links. I believe it to be those as the last time it got bad, I removed and reset the bar and the popping went away for quite awhile. Now it's back :/ I do takes corners hard quite often so it would be overall beneficial to change them as they are extremely worn.

My sound seems to be the same as gareyc, like a coat hanger tapping against the side metal under the speakers in the trunk. I am thinking something has to be loose or something with the the rear upper shock mounting. My mechanic says that if its suspension related it will be more of a knocking louder sound. But thats the only thing I can think of, also I actually had the car jacked up on the opposite rear side for like a week (I know i'm an idiot, ended up stressing out the scissor jack and had to replace) and after that is when the noise began. Could i have stressed out the shock mounting since all the weight in the rear was sitting on this 1 shock for almost a week.

Here this cracking and popping noise all the time from coupes and from M35 models and I know it sounds stupid but it is the rear shocks causing it. It is something with the mount that goes on top of shock and only way we have been able to fix is by replacing the rear shocks. Hope this is your noise and hope this fixes your issue brother.

From what the video sounds like I would be leaning towards the rear shocks unless for some reason one of the baffles broke loose inside the fuel tank. I have seen it on the JX models with the fuel tank doing this. The shock issue can be heard plain as day inside the car like this though.

I was suspecting the rear shocks too, but the noise is very loud and seems like it is coming from the inside, so I was not sure. Thank you Jason! I appreciate your help brother. I am going to order 2 rear shocks and 2 shock mounts soon for $92.19. Both are KYB, which I heard is a reliable brand. Quick question, do you know how much a mechanic shop would charge to replace broth sides?

I just replaced the rear shocks (KYB) on both sides, and I can still hear the noise when I go over a bumpy road or take a turn. My mechanic removed everything in the trunk and rear, but could not figure out what it is. He said nothing is loose and everything is in place. He said he gave up...
Sigh...any suggestions?

Update: problem solved! The noise is gone finally! The user Blue Dream was right. This is what he said, "sedans have a grey X brace behind the rear seats. Over time the bolts holding it tight can loosen and cause the same sound you're describing. The fix is relatively simple, remove the rear seat backs, tighten the bolts with a little Loctite, and put the seats back."

Ive been having the same problem. Its coming from where my spare tire is. There are 2 plastic frame type objects that surround the tire, which are missing some nuts/washers. Went to Autozone to buy 6 of each. Tommorow Im going to a car wash to vacuum all these loose fragments down in the spare tire compartment which broke due to an car accident, then going to install the nuts in the plastic things surrounding the tire.
