Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Tire Pressure Adjustment

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

3. Wheel Alignment

Tools Required: Alignment machine, wheel chocks, and a torque wrench.
Position the vehicle on an alignment rack and attach the alignment sensors.
Adjust the alignment settings to the manufacturer specifications for camber, caster, and toe.
Confirm adjustments are within the acceptable range and lock the settings.

4. Suspension Inspection and Repair

Visually inspect suspension components for any signs of wear or damage.
Replace any worn struts, shocks, or bushings as necessary.
- Sub-steps:
  - Lift the vehicle using a jack and secure it on jack stands.
  - Remove the wheel to access suspension components.
  - Replace components using a socket set and torque them to the manufacturer specifications.

5. Final Check and Tire Rotation

Rotate tires if uneven wear is noted to extend their lifespan.
Use a torque wrench to tighten lug nuts to the specified torque.
