    CURB HEIGHT MEASUREMENT (LD)
    The wheet alignment is to be checked and all alignment adjustments made with the vehicle at its required curb
    height specification.
    Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack. The
    tires are to be inflated to the recommended pressure. All tires are to be the same size as standard equipment.
    Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
    Inspect the vehicle for bent or weak suspension components. Compare the parts tag on the suspect coil spring(s)
    to the parts book and the vehicle sales code, checking for a match. Once removed from the vehicle, compare the
    coil spring height to a correct new or known good coil spring. The heights should vary if the suspect spring is weak.
