hey guys, yesterday i had to have my poor mazda towed home. something on the passenger side is shaking horribly at about 30mph. i took the wheel off and i cant see anything wrong, nothing at all. the steering wheel also turns back and forth slightly with the shaking. it only does it when i step on the gas as well. you guys got any clue to what this could be? i thought maybe a wheel bearing or tie rod, but i cant see or do anything with the wheel off to make the sound or shaking.
