Sub-steps:
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate tires to the manufacturer-recommended specifications found in the owner’s manual or on the driver's side door jamb.
Tools Required: Tire pressure gauge, air compressor or tire inflator.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount each wheel on a wheel balancer.
- Add wheel weights as necessary to achieve balance.
- Reinstall wheels on the vehicle, tightening lug nuts to the specified torque (typically 76 ft-lbs for the Highlander).
Tools Required: Wheel balancer, socket set, torque wrench.

4. Wheel Alignment

Sub-steps:
- Use an alignment machine to check the alignment settings.
- Adjust toe, camber, and caster angles according to manufacturer specifications.
Tools Required: Alignment machine.

5. Suspension Inspection and Replacement (if necessary)

Sub-steps:
- Inspect control arms, tie rods, and ball joints for wear or damage.
- Replace any worn components, ensuring that new parts are installed according to the specifications.
Tools Required: Socket set, wrenches, possibly a press for bushings.
