The problems in steering, suspension, and in tires and wheels involve several systems. Therefore, all must be considered when diagnosing a complaint. Always road test the vehicle first to avoid using the wrong symptom. Allow for road surface imperfections and allow for road crown when road testing a vehicle. The test route chosen must resemble the average surface the customer utilizes in order to duplicate the complaint.

Proceed with the following preliminary checks. Correct any substandard conditions found.

Inspect for the following:

    • Inspect for improper tire pressure.
    • Inspect for uneven wear on tires.
    • Inspect the power steering fluid level.
    • Inspect for wear on joints from the steering column to the steering gear.
    • Inspect for loose or damaged parts on the front suspension.
    • Inspect for loose or damaged parts on the rear suspension.
    • Inspect for loose or damaged parts on the steering gear.
    • Inspect for loose or damaged parts on the steering linkage.
    • Inspect for components that are out-of-round.
    • Inspect for tire imbalance.
    • Inspect for wheel damage.
