Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Wear safety glasses and gloves.

2. Tire Pressure Check

Use a tire pressure gauge to check the inflation of all tires.
- Sub-steps:
  - Ensure that all tires are inflated to the recommended pressure listed on the driver's side door jamb.
  - Adjust pressures as necessary.

3. Alignment Adjustment

If tire pressures are correct, proceed to alignment adjustment.
- Sub-steps:
  - Position the vehicle on an alignment rack.
  - Follow the manufacturer's specifications for adjusting camber, caster, and toe settings.
  - Make necessary adjustments to bring the alignment within specification, typically adjusting toe to zero for straight tracking.

4. Suspension Component Inspection

Inspect and replace any worn or damaged components.
- Sub-steps:
  - Check for play in ball joints and tie rods by shaking the components while the vehicle is raised.
  - Replace any worn bushings or components that show signs of damage.
  - Re-torque all components to manufacturer specifications after replacement.

5. Final Tire Rotation

Rotate the tires to ensure even wear, if necessary.
- Sub-steps:
  - Move the front left tire to the rear left position and vice versa, depending on wear patterns.
  - Ensure all tires are balanced after rotation.
