OK, Wife has a 2005 Mazda 3 I 2.0 AT

125K Has developed a ROTATIONAL noise that increases with speed and gets louder when turning, more so turning right.

I replaced the DS hub and bearing. NOT FIXED
I replaced the DS axle assembly. NOT FIXED

Tires look good, pads are new. Rotors appear straight. (Doesnt sound like rotor noise) Calipers work good.

Sound like its coming from the left side.(DS) I am at a loss.
This is driving me nuts, although only 225 bucks down, Im replacing stuff I didnt need to, and the noise is still there. It vibrates some, not as much of a vibration as noise. Brakes very solid and smooth.

HELP?????

well since you replaced the hub & bearing on one side... aren't they symmetrical, so you can reinstall that one on the right to see if the sound changes (since it apparently wasn't the bearing / hub on the left).

Try rotating the tires, I know my step sis's monte carlo had horrible tire noise - sounded just like a wheel bearing but didn't change with steering.

is the sound a grumble, whine, clicking... describe it a bit please. And I assume it's only when driving or you wouldn't have been looking at rotational things.

Mr.Mango

Do you have access to a hoist? If so run the car in the air. If the issue goes away more than likely its cupped tires if you have already replaced wheel bearing & axle shaft.

If no access to hoist state with tire rotation front to back
