RIDE HEIGHT ADJUSTMENT

Specifications are given for side-to-side or front-to-rear height tolerance. If vehicle is not within side-to-side or front-to-rear specifications, replace damaged or worn components as necessary.

1. Before adjusting alignment, check ride height. Ride height must be checked with vehicle on level floor and tires properly inflated. Bounce vehicle several times and allow suspension to settle.
2. Remove any extra heavy items from passenger and luggage compartments. Visually inspect vehicle for signs of abnormal height from front-to-rear or side-to-side.
3. Measure from center of wheel to lip of wheel arch. Measure and note distance at all wheels. Maximum difference between left front and right front and between left rear and right rear should be less than specified.
