I have a light creaking noise coming from the rear hatch. I hear it every day but it only happens in the first 30-60 seconds of driving after the car has been sitting for a few hours. I will hear the noise when going over any kind of bump or undulation in the road. I have an uphill speed bump exiting my garage and I also hear the noise as soon as I dip the clutch to go over the speed bump.
It's weird......sounds like it might be coming from the strut tower in the rear because it's more a plastic/aluminum type of creaking than a metal clunking. Car is a year old with 20k. The noise has been there a few months now.

Anyone got any ideas before I take it in for the next service?

 

it's probably the rear axle. There is an issue with the 350z re: the rear axle clicking noise, there is a TSB out for it.

 

rear axel i just got mine fixed 3 days ago

 

I have the same noise and then it goes away..

 

Thanks for the responses but I don't think it can be related to the rear axle. If this was the case, I would have expected to here the noise also on smooth pavement. The creaky noise is only there when I go over a bump or uneven section of road. Therefore, it would appear to be suspension related. Definitely sounds like it's coming from the rear strut beam.

 

I also have that same creakin noise as well. I also hear mine as I'm going over speed bumps in my parking garage. Could this be the rear axle? Mine sounds more plastic than anything as well. I thought it might be the foam padding that is in the spare tire area, but I can't confirm that while driving. Anyone know what causes that noise???

 

Could be the rear strut brace moving inside the decorative Z cover. I hear this when I'm going up a driveway at an angle.

I also have the rear axle click, it's being done on monday the 27th

 

Yip, I think you could be right about the strut brace moving or rubbing against the plastic silver "Z" cover. Do you know how to remove the cover so I can take a look inside?

 

i have the exact same noise you guys are talking about ....its driving me crazy.... i cant tell if its coming from the hatch or that strut

 

I hear it when going up my driveway at an angle.

 

The plastic pieces just snap together. Remove the two upper covers on each side of the silver piece, then you will see the logical order. I have a "buzz" that only seem to happen when it is cold. I removed the strut cover, but it still occurred. I'll keep trying.
