Solution

1. Preparation

Gather tools including a tire pressure gauge, alignment rack, and basic hand tools.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Tire Pressure Adjustment

Sub-steps:
1. Use the tire pressure gauge to measure the pressure of each tire.
2. Inflate or deflate tires as necessary to match the manufacturer’s recommended pressure (found on the driver’s door jamb).

3. Tire Rotation and Inspection

Sub-steps:
1. Jack up the vehicle and secure it on jack stands.
2. Remove the front tires and inspect for uneven wear.
3. If uneven wear is found, rotate the tires to promote even wear; if the tires are damaged, replace them.

4. Wheel Alignment

Sub-steps:
1. Position the vehicle on an alignment rack.
2. Follow the manufacturer’s specifications to adjust camber, caster, and toe settings as needed.
3. Ensure all adjustments are within manufacturer specifications for the Highlander.
