I have a creaking sound near sunroof or rear passenger corner of roof in my 2004 G35X sedan. Anyone have any ideas how to hunt this down? I have tried rolling up and down that rear window and opening/closing the sunroof.

 

heres is something i just posted somewhere else on here, maybe it will help.

i attempted to find my annoying creak in the inside toward the back, which happens when i go over big bumps or turning into my driveway over small curb/ramp up when the car is twisted up.

i FOUND my problem, there is a gray cross brace behind the seats and some sound proofing mat, those screws/bolts were very loose and when i tightened them the creak went right away ! that saved me some coin from going to the dealer out of warranty !

i suggest if you have the creak in the rear that sounds loud inside tighten up everything you can find behind the seats(you have to take the seats out, buts it easy)

i have a G35X sedan.

 

i have this creek..im gonna try this out.

 

Hmmmmmm

 

ive heard this annoying creek twice in the past week now.. I've been wanting to tighten things up behind the back seats anyway, ill have to try that this weekend if i get a chance

 

I'm hearing a creak, cracking sound too, also hear damn squeak coming from the interior rear. Is there a DIY on how to remove rear seats? Might tackle this tomorrow morning.

 

took out rear seats, tightened up bolts on cross metal bars behind seats. Seems like creaking, cracking sound is gone. Not all but a few of them were very loose.

 

did the same today.. same here, a few were not super tight, everything else was really tight. Tightened up the arm rest too.. and the child seat had one possible squeaky area, fixed that.. tonight it seemed nice and quiet. Have a long drive tomorrow, hopefully its fixed

 

ha, cool....next is felt tape on door panels

 

yeah did that last fall on my passenger front door, did the trick! My other doors havent acted up yet..
