Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: Tire pressure gauge, jack and jack stands, torque wrench, alignment machine (if available).
Parts Required: New tires (if uneven wear is severe), alignment shims (if needed).
Ensure the vehicle is on a flat surface and the engine is off.

2. Adjust Tire Pressure

Use the tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to reach the recommended pressure as specified in the owner’s manual.

3. Rotate Tires

Jack up the vehicle and remove the tires.
Follow the recommended tire rotation pattern for the Highlander (e.g., front to back, or crisscross).
Reinstall tires and ensure they are tightened to the manufacturer's torque specifications.

4. Perform Wheel Alignment

Use the alignment machine to check the alignment angles (camber, caster, toe).
Adjust angles to meet the manufacturer's specifications, making sure all bolts are tightened appropriately.

5. Inspect and Replace Suspension Components

Check the condition of shocks, struts, and bushings.
Replace any worn or damaged components as needed, following standard removal and installation procedures.
