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 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.
1. Front Wheel Center Height - Measure the vertical distance between the front wheel center (1) and the ground (3).
2. Front Cradle Height - On each side of the vehicle, measure the vertical distance between the center of the lower control arm forward pivot bolt (2) to the ground (3) Record the measurement.
3. Take the two measurements and subtract them to get the ride height specification.
4. Rear - On each side of the vehicle, measure the distance from the axle tube (2) and the bottom of the upper spring perch (1).
