Solution

1. Preparation

Tools Required: Alignment rack, tire pressure gauge, basic hand tools (sockets, wrenches), torque wrench.
Ensure the vehicle is parked on a level surface and that the tires are inflated to the correct pressure.

2. Adjust Toe Angle

Sub-steps:
1. Release the lock nuts on the tie rod ends using the appropriate wrench.
2. Adjust the tie rod ends to achieve the correct toe specifications (typically 0.04 to 0.12 degrees for the Highlander).
3. Tighten the lock nuts back to the manufacturer's torque specifications (usually around 45-55 ft-lbs).

3. Adjust Camber Angle

Sub-steps:
1. If the camber is out of specification, loosen the bolts on the strut assembly.
2. Adjust the strut to align the camber angle to within the manufacturer's specifications (typically -0.5 to 0.5 degrees).
3. Retighten the strut bolts to the specified torque (usually 50-60 ft-lbs).

4. Adjust Caster Angle (if necessary)

Sub-steps:
1. If caster requires adjustment, it may involve shimming or moving the control arm.
2. Follow manufacturer guidelines for any special tools or alignment kits required.
3. Ensure the caster angle is set within manufacturer specifications (typically 3.5 to 4.5 degrees).

5. Final Checks

Sub-steps:
1. Recheck all adjustments with the alignment machine.
2. Make any final adjustments as necessary.
3. Perform a test drive to ensure the vehicle tracks straight and handles properly.
