Solution

1. Preparation

Tools Required:
- Tire pressure gauge
- Jack and jack stands
- Wheel chocks
- Alignment tools (alignment rack or laser alignment tool)
- Torque wrench
Instructions:
- Ensure the vehicle is parked on a level surface.
- Gather all necessary tools and parts before starting.

2. Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all four tires.
Inflate or deflate tires to match the manufacturer's recommended specifications found in the owner’s manual or on the door jamb.

3. Inspect Tires

Remove each front tire to check for uneven wear.
Replace tires if tread is below 2/32 of an inch or if they are damaged.
Rotate tires if necessary to ensure even wear.

4. Perform Wheel Alignment

Instructions:
- Use an alignment rack or laser tool to measure the alignment angles.
- Adjust the toe, camber, and caster angles according to OEM specifications.
- Tighten all adjustment bolts to the manufacturer’s specified torque values.

5. Inspect and Replace Suspension Components (if necessary)

Visually inspect control arms, bushings, and ball joints for wear and damage.
Replace any damaged components, ensuring all new parts are torqued to manufacturer specifications.

6. Final Checks

Reinstall the front tires and ensure they are torqued to the correct specifications.
Lower the vehicle from the jack stands and remove wheel chocks.
