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 unladen of any cargo, but including spare tire, tools, accessories, and fuel tank full.

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. Rear - On each side of the vehicle, perform the following on both sides:
   • Measure the distance from the control arm bolt head to the floor or alignment rack/lift runway surface (1).
   • Measure from the center of the spindle to the floor or alignment rack/lift runway surface (2).
2. Subtract measured distance 2 from 1 to find the rear ride height value, which will result in a negative number. (Measurement 1 - Measurement 2 = Ride Height).
