noise coming from rear by judysteele

The noise is a deep humming sound, no vibration. Starts at about 35mph and stops at 60 and when I am just applying steady pressure on the gas pedal. If I push the pedal or let off it the noise will stop.
Makes no difference what type of road surface.
Sometimes the noise will start right away and next time I might have to drive for 15/20 minutes.
I tried to record the sound before I take it to the dealer, but I pick up to much road noise.
Any suggestions?

It's FWD. Also I don't get any noise turning left or right.
From what I've read about wheel bearings that was my first thought, but shouldn't they make a noise all the time?

They will make the noise under the right circunstances (whatever that might be). The turning thing is just more prevalant when its a front wheel bearing. In my case (Pontiac version) with the rear bearing, it did make more noise when making high speed turn (such as an exit ramp while traveling in excess of posted limit ), not that I suggest doing that. Does sound like bearing issue to me.

If it is a bearing going out shouldn't it make a noise all the time? If I remember right, in the 'old' days when a bearing was going out it would sound like stones in a hubcap,
We've always done our own work on our vehicles, but these new ones are getting complicated and now you almost have to go to a garage for repairs.

Stuff is different these days, materuals and tech specs have changed. The symptoms (noticable) have changed also. One other thing I remember when rear bearing was failing is in my case when driving (and creating noise) on a bumpy road the noise would waver when load was taken off wheel (as in the downside of bump)

Loud buzzing sound from left rear by firetrucker

I have a '03 CX and recently had the fuel pump replaced. Not long after that a buzzing roar began in the left rear of the car. It doesn't change pitch when the gear shift, just a steadily increasing sound the faster it goes. I've noticed it changes when I take either a left or right turn enough to shift the weight over it. Is it a bearing going out or maybe something didn't get tightened up during the repair to the pump?

If this noise occurs only when turning, then your rear differential fluid must be changed. It is a very easy 5 minute job. you will need only a metric # 8 Allen type wrench and 2 quarts of VersaTrac fluid..$35 per quart. My Buick dealer tried to charge me $425 to do the job. RPM Automotive quoted $190. I did it myself because it is literally easier than changing the engine oil. The are 2 drain plugs on the diifferential revove them both and drain the fluid thoroughly. replace the bottom plug, then squirt the 2 quarts of fluid in through the top plug. Re-plug and go for a drive and do a series of fiure-8s. Mine stopped whining within 2 miles. Good luck.

Rendezvous Interior Noise by suv_guy_19

Our Rendezvous have terrible noise coming from the rear end when going over bumps. It seems to reverberate through the cabin as if someone is clapping their hand over your ears on certain surfaces.
 
On other surfaces, such as a freshly seal coated road, the road noise is just terrible.
 
When we first tested the vehicle, I have no memory of it being like this.
 
Does anyone else have this problem? I seriously need help with this. There is some type of fix to the rear floor that somone mentioned here, but the dealer near me says them haven't heard of it. Please help!
