ok guys, heres the deal, today i changed the right front wheel bearing/hub assembly, i noticed an allen bolt on the hub which looked like it was securing something like a washer on it, but whatever it was, it was rusted away, so i didnt put it back on the new hub, now i am getting the blasted shimmy when driving, and its very harsh when braking, it feels like everything under the car is falling apart, question, what the hell was the allen bolt securing and it this bolt the cause of the shimmy?
thanx in advance
