Noticed that at speed above 30km/h I got vibration from rear-right wheel. Faster I go - vibration became more frequent and at highway speed turns into noise. Definitely it is connected to wheel rotation. A person siting at the rear right seat feels vibration. I don't really feel it only hear. No brake pedal popping or something like that, no steering wheel vibration.

I have new brake disks at the rear(3 weeks old), and replaced sway arm bushings, week ago went to Wallmart Tire and Lube and requested rear wheels balancing, didn't help.

Before visiting mechanic I would prefer to try fix it myself, of at least understand what is going on.

Aftermarket wheels? New rotors and pads? Had a reprint of the service procedures on the Impala forum about somthing similar to this...might want to read the loooong post there.

Check for bad wheel bearing, jack wheel and see if is loose.

Could also be a missing wheel weight! Sometimes those things can fall off. I don't really think you can fix that yourself though, re-balancing the tire is the only way I think.
