2. Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor.
Check the tire pressure for all tires and inflate them to the recommended PSI as per the owner’s manual.

3. Tire Rotation

Tools Required: Jack, jack stands, lug wrench, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts using a lug wrench.
Rotate the tires according to the recommended pattern (e.g., front to back, or cross-pattern).
Reinstall lug nuts and torque them to the manufacturer’s specifications (typically 76-80 ft-lbs for Highlander).

4. Wheel Alignment

Tools Required: Alignment rack, camber/caster gauge.
Use an alignment rack to check and adjust the alignment settings.
Adjust the camber, caster, and toe angles to factory specifications as outlined in the service manual.

5. Suspension Inspection and Repair

Tools Required: Socket set, wrenches, pry bar.
Inspect suspension components, including control arms, bushings, and struts.
Replace any worn or damaged components as needed, following manufacturer specifications for torque and installation.

6. Final Tire Inspection

After adjustments, recheck tire condition and tread depth.
Ensure all tires are balanced properly.
