rumble sound coming from my rear end?
It start 3000 miles ago. It's coming from my rear end at any speed and It's a rumble sound. Very difficult to explain and It's worst when all my windows are close. Each week my sound is a bit louder. The dealership say that is coming from my tires (so4) but I change them and the sound is still there.
2010 with 35000 miles
Btw sorry for my crappy english.

If your tires are cupped it will make a bad rumble noise but you said you replaced them. Could be a bad wheel bearing. Go to a long empty road and bring the car up to speed where you hear the noise and steer the car from side to side. If the noise goes away when turning a particular way, it's a good indication that a wheel bearing has gone bad on the side you are turning towards. Another thing you may want to check is the rear differential. I've never had a differential go or start to go so I don't know what kind of sound it produces.

I bring the car at 40mph and I try to steer the car side to side and the noise is still there . I start to think It's my differential but on my cts-v back in the time have a differential problem and the noise was different

Sometimes when a wheel bearing is really bad, the noise won't go away. Jack the back up and turn the wheels. If the bearing is ready to fall apart you may hear it just by spinning the wheel by hand. Even keep your hand on the wheel when spinning, see if you can feel anything. Obviously you won't be able to produce the same noise when doing this because the car is not under load or with high speed so you will have to pay real close attention. I'm the furthest thing from a mechanic but this is what I would do. Maybe next step is to get it on an independant shop hoist and get it up to speed and see if you can hear it this way.

Spin it? Don't waste your time. Grab the wheel either side to side or top to bottom and try to lever it off the hub. If there is any play in it at all, the wheel bearing on that wheel is shot. The wheel should feel completely solid - any movement you can feel is bad.
