I have been having this problem for a while and it comes and goes. I did a search and no one really has the same problem. my front pass. wheel shakes and makes noise on and off? it can be driving smooth and then all of a sudden it does it. then it will go away. sometimes feels like the wheel is gonna break it does it so bad. I originally thought my wheel needed balanced because their is no wheel weight on it...but why would it come and go? It seems to do it after hard breaking but not all the time. Rotors do not pulse all the time when brakeing. Any ideas? Wheel bearing maybe....?
