SUSPENSION DIAGNOSIS

Inspection and Verification

1. Road test.

- Verify the customer's concern by performing a road test on a smooth road. If any vibrations are apparent, see Suspension NVH Diagnosis.

2. Inspect tires.

- Check the tire pressure with all normal loads in the vehicle and the tires cold; See the vehicle certification (VC) label; See Wheel and Tire Inspection / Adjustment.
- Verify that all tires are sized to specification.
- Inspect the tires for improper wear and damage; See Wheel and Tire Inspection / Adjustment.

3. Inspect 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, wheel and tire components (such as competition, heavy duty, etc.). The specifications shown in this information do not apply to vehicles equipped with aftermarket equipment.
