Whenever i drive, my steering wheel will shake, and it's variable to the tires rotation, it's a odd type of shaking...like it'll turn a little bit, the re-adjust itself probably once or twice a rotation...I know it's not the rotors, so could it be just a unstable wheel?

 

mine does the same thing... som info please cause it is teh suxor

 

wheel balance maybe...
got hub-centering rings?

 

you might want to re-balance the wheels if it's not the rotors. also check the alignment and the treadwear of your tires. also make sure you lugnuts are tightened to torque specs.

 

mine does that when im slowing down off the highway or from highspeeds, its kinda scary my altima doesnt do that.

 

If it's when your slowing down, your rotors have probably warped and either need shaved or replaced. If you only really notice it as the speed goes up, you probably need your wheels balanced or you alighnment is out of spec.

 

Rotors most likely warped, when you're coming to a complete stop do you hear a scraping kinda noise as you're slowing down?

happened to mine, rotors were the problem, got new ones, problem went away.
