Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use jack stands to support the vehicle securely.

2. Tire Rotation

Sub-steps:
1. Loosen the lug nuts on the front tires while the vehicle is still on the ground.
2. Use a jack to lift the front of the vehicle and secure it with jack stands.
3. Remove the front tires and swap them with the rear tires to promote even wear.
4. Tighten the lug nuts to the manufacturer’s specified torque (usually around 76 ft-lbs for Toyota).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment service.
2. Ensure that the alignment settings are adjusted to the manufacturer’s specifications (typically, the camber, caster, and toe settings).
3. Test drive the vehicle to confirm it tracks straight and to check for any new wear patterns.

4. Suspension Component Replacement

Sub-steps:
1. Inspect and identify any worn suspension components.
2. Replace any damaged or worn parts (such as control arms, bushings, or struts) with OEM or quality aftermarket parts.
3. Recheck the alignment after replacing any suspension components.
