Hey guys, I have a 2003 350z and there is some creaking/squeaking coming from the drivers rear tire. It sounds like someone is jumping on an old mattress. I checked the brakes, there all new and its not the dust shield or wear indicators, so this leads me to suspect a wheel bearing. When I turn right, the noise amplifies and increases, when I turn left, it goes away, and when I let off the gas, I can hear it. Here is a video:

 

Any luck discovering what caused this creaking?

I just purchased my 2003 Z and am experiencing this issue verbatim as you described it. Would love to know if I'm about to get pwned when I take it to the mechanic next week

 

I have this same noise... It's either your brakes or wheel bearing. Could be axle too.. have fun (I'm just driving with it until I have money to upgrade my brakes) There are also many other threads about this.. I have read over 20 other different threads... all say the same 3 things. Bearing, brakes, or axle.
