Ride Height Correction

WARNING:Turn off the air suspension service switch located in the jack stowage area in the rear of the vehicle. (With automatic ride control only).

NOTE: Perform this procedure if the torsion bars, torsion bar adjusters, or front suspension lower control arms have been removed from the vehicle.

1. Raise and support vehicle.
2. Disconnect front and rear air lines at shock absorber.
3. Lower vehicle on slip plates to perform ride height setting.
4. Bounce vehicle's front and rear suspension to normalize static ride height.
5. Measure distance between front suspension lower arm bushing center bolt and ground, Fig. 6. Record this as dimension "A."

Fig. 6 Vehicle Ride Height Dimensions:

6. Measure distance between front suspension lower arm bushing center bolt and the ground (flat surface-see dimension A, Fig. 6.) Record measurement.
7. Measure the distance between the front suspension lower arm (lowest point) (see item 8 in view D, Fig. 6.) and ground (dimension B). Record measurement.
8. Subtract dimension B from dimension A for ride height.For vehicles without Automatic Ride Control (ARC), ride height should be set to 110-116mm (4.33-4.56 inches). For vehicles with ARC, ride height should be set to 83-89mm (3.26-3.50 inches). This is done to allow for settling of new parts.
9. Raise vehicle to adjust torsion bars (height).

NOTE: When performing an alignment check only, the ride height should check between 91-111mm (3.58-4.37 inches) for vehicles without ARC. Vehicles with ARC the ride height should be 69-89mm (2.7-3.5 inches).
