What other things can cause steering wheel shake? It acts like a wheel is out of balance but the weird thing is that it doesn't happen all of the time. Both wheels are in perfect balance and the front end has been aligned. I thought a rotor may be warped but I changed those out during the last brake job and there was no change. The car doesn't pull to either side driving or braking. I just don't get why it doesn't do it all of the time ... it just comes and goes for no attributable reason.
