Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Adjust Tire Pressure

Use a tire pressure gauge to check all tires.
Inflate or deflate tires as necessary to match the recommended pressure found in the owner's manual.

3. Inspect and Replace Tires (if necessary)

Check tires for uneven wear or damage.
If uneven wear is found, replace the affected tire(s) with tires that match the specifications for the Highlander.

4. Wheel Alignment Adjustment

Raise the vehicle using a hydraulic lift or jack stands.
Remove the front wheels for better access to alignment components.
Use an alignment machine to measure and adjust:
- Camber
- Caster
- Toe settings
Adjust the tie rods and other components to the manufacturer’s specified angles.
Reinstall the front wheels and torque to manufacturer specifications.

5. Inspect and Repair Suspension and Steering Components

Inspect control arms, tie rods, and bushings for wear.
Replace any damaged components as necessary.
Recheck alignment after any repairs.
