Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, alignment machine, torque wrench.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Wear safety gloves and goggles for protection.

2. Tire Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to check the pressure of all four tires.
- Inflate or deflate tires as necessary to match the recommended pressure found in the owner’s manual or on the driver’s door jamb.

3. Tire Rotation or Replacement

Sub-steps:
- If uneven tire wear is observed, consider rotating the tires front to back.
- If wear is excessive or uneven, replace tires as needed, ensuring they are of the same type and size.

4. Suspension Component Inspection

Sub-steps:
- Lift the vehicle using a jack and secure with jack stands.
- Inspect control arms, tie rods, and bushings for cracking or deterioration.
- Replace any damaged components with OEM or high-quality aftermarket parts.

5. Wheel Alignment

Sub-steps:
- Position the vehicle on an alignment rack and attach the alignment sensors.
- Adjust the camber, caster, and toe settings to the manufacturer’s specifications.
- Torque all adjustment bolts to the specified values using a torque wrench.
