Hey guys I've got an 06 Z and there is some type of "clangy metallic sounding" rattle coming from under the car during low RPMs. For example, I hear it really loud when starting to move in first gear or when downshifting/braking. Any idea what this issue could be (before I go insane)? Thanks lol

 

Don't know. I would have to get under the car for a listen.

BTW I had a rattle under the 350Z for about 6 months. Drove me insane. Finally figured out is was a broken exhaust support.

Good luck.

 

next time go under your car in the rear where your exhaust muffler connects to the end of the midpipe, feel around the screws maybe its loose and that causes rattles but disappears after u drive faster, Good luck!

 

Agree.. Go under the car with it on. Can you get someone to rev it a little and you lay on the ground listening for it. It has to be the exhaust. Especially if the car isn't moving.

Good luck.. Its those rattles that drive you fricking insane.

 

I have the same problem. For me simply revving the engine while stationary will not make the sound. Its only when the car is in gear and moving in low rpm is when the rattle sound is made. I will have to check for loose pipes.

 

Is the car modded? I know when i put in test pipes, i didnt take the heat shields out and they rattled when down shifting. Took them out, and no more rattle.

 

2, either cats shields or mufflers. There's a piece of shield by mufflers you can bend that will rattle at low rpm. Get under car and look its exhaust for use just figure out what

 

i just noticed I have it too. If I'm in neutral and i rev a tiny bit from .7 rpm to about .9 I get a pretty loud rattle. The rattle sounds like it comes from under the clutch though. loose pipes maybe?

 

Possibly a throw-out bearing, Nissan's bearings sometimes last the life of the car and other times a few thousand miles before they begin to rattle.

 

ur gonna have to get under and shake things around with the car off first, then have someone rev it up while ur under it listening..how do u expect people to diagnose this over the internet..really

 

thanks all, i'm excited about getting horizontal with my Z this weekend. will update after the special day...

 

I removed my heat shield, under load at low rpms it would rattle like crazy
