Curb Height Measurement

The wheel 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, and no passenger or luggage compartment load.

Vehicle height is not adjustable. If the measurement is not within specifications, 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.

1. Front Curb Height  - On each side of the vehicle, measure the distance (Dim A) from the center of the wheel to the floor, and measure the distance (Dim B) from the rear lower control arm bolt to the floor or alignment rack/lift runway surface. The final curb height measurement (Dim C) is calculated by taking (Dim A) minus (Dim B). It may be necessary to measure to the bottom of a straight edge, placed from lift runway to runway, to get an accurate measurement.

2. Rear Curb Height  - On each side of the vehicle, measure the distance (Dim A) from the center of the wheel to the floor, and measure the distance (Dim B) from the front cradle mounting bolt to the floor or alignment rack/lift runway surface. The final curb height measurement (Dim C) is calculated by taking (Dim A) minus (Dim B). It may be necessary to measure to the bottom of a straight edge, placed from lift runway to runway, to get an accurate measurement.
3. Compare the measurements to the specifications listed in the following Curb Height Specifications chart.
