Solution

1. Preparation

Gather tools including a tire pressure gauge, alignment tool, jack, jack stands, and a torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Pressure Adjustment

Remove valve caps and check tire pressures using a tire pressure gauge.
Inflate or deflate tires to match the recommended pressure (typically found on the driver’s door jamb).
Reinstall valve caps securely.

3. Tire Rotation

If tire wear is not consistent across all tires, rotate tires to promote even wear.
Lift the vehicle using a jack and securely position jack stands.
Remove each tire, swapping front to back and side to side, as per the manufacturer's rotation pattern.
Reinstall tires and torque lug nuts to the specified value (usually around 100-120 ft-lbs).

4. Wheel Alignment

Use an alignment tool to check the camber, toe, and caster settings.
If misalignment is detected, adjust according to manufacturer specifications, typically found in the service manual.
After adjustments, confirm all settings are within acceptable ranges.

5. Suspension Inspection (if needed)

Examine all suspension components for wear, including bushings, struts, and control arms.
If damaged components are found, replace them using the appropriate repair procedures for each component.
