Solution

1. Preparation

Gather necessary tools:
- Tire pressure gauge
- Jack and jack stands
- Wrench set
- Wheel alignment tools
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Adjust Tire Pressure

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

3. Perform Alignment

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a wrench set.
Attach alignment tools and adjust the camber, caster, and toe angles according to the specifications in the service manual.
Reinstall the front wheels and lower the vehicle.

4. Inspect and Replace Suspension Components (if necessary)

Check the condition of bushings, ball joints, and tie rods.
If any component is worn or damaged, replace it with a new part.
- Tools Required: Wrench set, possibly a ball joint separator.
Follow torque specifications for reassembly.

5. Tire Rotation and Balancing

Rotate the tires according to the vehicle’s maintenance schedule (e.g., front to back and side to side).
Balance the tires using a tire balancer to ensure even distribution of weight.
