Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, level surface.
Disconnect the negative battery terminal if working on electrical components.
Tools required: jack, jack stands, tire pressure gauge, alignment tool, socket set, torque wrench.

2. Tire Pressure Adjustment

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

3. Tire Inspection and Rotation

Remove each wheel using a socket wrench.
Inspect tires for uneven wear patterns and replace if necessary.
Rotate tires to ensure even wear (front to rear or side-to-side depending on pattern).

4. Wheel Alignment

Using an alignment machine, check the alignment settings (camber, caster, toe).
Adjust the alignment to factory specifications, tightening all related bolts to the manufacturer's torque specifications.

5. Suspension Inspection and Repair

Inspect all suspension components for wear (bushings, ball joints, struts).
Replace any worn components with OEM parts.
Torque all fasteners to the recommended specifications.

6. Steering System Check

Inspect tie rods and steering rack for any signs of wear or damage.
Replace any worn tie rods or steering components as needed.
