Initial Inspection and Diagnostic Overview

SUSPENSION SYSTEM - DIAGNOSIS AND TESTING

Inspection and Verification

1. Road test the vehicle.

- If any suspension alignment or ride height concerns are present, see - Suspension System.
- Verify the customer concern by carrying out a road test on a smooth road. If any vibrations are present, see - Noise, Vibration And Harshness (NVH).
- This vehicle is equipped with electronic drift/pull compensation. When evaluating a drift/pull concern, place both hands on the steering wheel while driving straight for at least 20 seconds. Then evaluate the drift/pull concern as usual. If lane changes are involved, repeat the 20 second test after each lane change.

2. Inspect the tires.

- Check the tire pressures with all normal loads in the vehicle and the tires cold. See the vehicle certification (VC) label.
- Verify that all tires are sized to specification. See the VC label.
- Inspect the tires for incorrect wear and damage. Install new tires as necessary.

3. Inspect the chassis and underbody.

- Remove any excessive accumulation of mud, dirt or road deposits from the chassis and underbody.

4. Inspect for aftermarket equipment.

- Check for aftermarket changes to the steering, suspension, and wheel and tire components (such as competition or heavy duty). The specifications shown in this information do not apply to vehicles equipped with aftermarket equipment.
