Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the PSI of each tire.
Inflate or deflate tires to match the manufacturer’s recommended specifications.
Recheck to ensure all pressures are accurate.

3. Tire Rotation

Loosen the lug nuts on the front tires slightly.
Raise the vehicle using a jack and secure it with jack stands.
Remove the front tires and install them on the rear, and vice versa (if uneven wear is suspected).
Tighten the lug nuts to the manufacturer's specified torque (usually around 76 ft-lbs for most Toyota models).

4. Wheel Alignment

Take the vehicle to a professional alignment shop or use an alignment kit if available.
Adjust the camber, caster, and toe settings according to the specifications provided in the service manual.
Ensure all adjustments are within the specified ranges.

5. Suspension and Steering Component Inspection

Visually inspect all suspension components for wear or damage.
If any components are found to be defective, replace them as necessary.
Check and tighten any loose bolts or connections in the steering system.
