Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Balancing

Sub-steps:
1. Remove the front wheels using a socket set.
2. Mount each wheel on the wheel balancer.
3. Adjust weights on the rim as indicated by the balancer until the wheel is properly balanced.
4. Reinstall the balanced wheels, ensuring they are torque to the manufacturer’s specifications (typically around 76 ft-lbs for the Highlander).

3. Tire Inspection

Sub-steps:
1. Examine each tire for visible signs of damage, such as cuts, bulges, or foreign objects.
2. Check tread depth across the tire surface using a tread depth gauge.
3. Replace any damaged or excessively worn tires as needed.

4. Suspension and Alignment Check

Sub-steps:
1. Inspect the suspension components for any signs of wear, including bushings and ball joints.
2. If any components are worn, replace them accordingly.
3. Perform a wheel alignment using an alignment machine, adjusting camber, caster, and toe angles to the manufacturer's specifications.
