Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, wheel chocks
Ensure the vehicle is on a level surface and securely raise the front of the vehicle using a jack and jack stands.

2. Adjust Tire Pressure

Sub-steps:
- Check the manufacturer’s recommended tire pressure found in the owner’s manual or on the driver’s side door jamb.
- Inflate or deflate the tires accordingly to match the recommended specifications.

3. Inspect and Rotate Tires

Sub-steps:
- Remove the front tires using a socket set.
- Inspect the tread depth and wear pattern on all tires.
- Rotate tires if uneven wear is noted (e.g., front to back or side to side).
- Reinstall the tires and torque the lug nuts to the manufacturer’s specifications.

4. Perform Wheel Alignment

Sub-steps:
- Use an alignment machine to check the alignment settings (camber, caster, toe).
- Adjust the alignment settings to meet the manufacturer’s specifications.
- Test the steering wheel position and ensure it is centered.

5. Inspect Suspension Components

Sub-steps:
- Examine control arms, ball joints, tie rods, and struts for any signs of damage or wear.
- Replace any worn or damaged components as necessary.
- Ensure that all suspension components are properly torqued per specifications.
