Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electronic steering components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to the manufacturer's recommended PSI (found on the driver’s side door jamb).

3. Tire Inspection and Rotation

Visually inspect each tire for uneven wear; replace tires if necessary.
If wear is uneven, consider rotating the tires to even out wear patterns.

4. Wheel Alignment

Position the vehicle on a wheel alignment machine.
Adjust camber, caster, and toe settings as per the manufacturer's specifications (typically around 0.5° positive camber, 0° toe).
Tighten adjustments to the specified torque values (check manufacturer specs).

5. Suspension Inspection and Repair

Inspect control arms, bushings, and tie rods for any signs of damage or wear.
Replace any worn components with OEM or equivalent parts.
Recheck wheel alignment after replacing suspension components.
