Toein/Toe out

To check the steering linkage ball joints (tie rod ends, idler arm, pitman arm) the vehicle should be resting on the ground while an assistant quickly jerks the steering wheel back and forth. While they are doing this place your hand on the joints and check for any movement. To check the ball joints, jack up the vehicle and rock the wheel in and out and check for movement in the joints as well as the wheel bearing.
