why does my f

It would be good to test drive it and feel what's going on exactly, but here: I assume your rims are good and tires are balanced. How about front shock absorbers, upper and lower control arms and steering shock? Zee

Does it shake all the time? when you brake? when you hit a bump? Probablyeither tires/wheels, brake rotors, or a steering stabilizer but a little more info would be helpful

When mine was doing it, it was the rear brakes.....
