I've had my 96 2wd 4runner for a few months now and they're was always shaking in the steering wheel causing the car to shake. The mud terrains were old and worn out figured that was the problem. Finally got new a/t tires and got them balanced. The shaking was reduced but still there so I got them rebalanced today but the shaking hasn't gone away. The shaking is all the time and gets a little worse when braking. So is it warped rotors? And/or time to replaces rack&pinion bushings, control arm bushings? I've already replaced ball joints
