Solution

1. Preparation

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

2. Tire Pressure Adjustment

Remove valve stem caps and use a tire pressure gauge to check the pressure in all tires.
Inflate or deflate tires to reach the manufacturer-recommended pressure, typically found on the driver's door jamb or in the owner's manual.

3. Tire Inspection and Rotation

Visually inspect all tires for uneven wear patterns and damage.
If uneven wear is noted, rotate the tires according to the recommended pattern in the owner's manual.

4. Alignment Adjustment

Using an alignment machine, check the camber, caster, and toe settings.
Adjust the alignment settings to meet manufacturer specifications, which typically requires loosening bolts and turning adjustment screws.
Torque adjustment bolts to the manufacturer's specified torque values.

5. Final Inspection

Once adjustments are made, perform a test drive to verify the vehicle tracks straight.
Recheck tire pressures after the alignment adjustment.
