Caster

STANDARD PROCEDURE - CASTER
Before each alignment reading the vehicle should be jounced (rear first, then front). Grasp each bumper at the center and jounce the vehicle up and down three times. Always release the bumper in the down position. To obtain an accurate alignment, a 4 wheel alignment machine must be used and the equipment calibration verified. The wheel caster angle is preset. This angle is not adjustable and cannot be altered.
