Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

Sub-steps:
1. Loosen the lug nuts on all tires slightly, but do not remove them.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the tires.
4. Rotate the tires according to the manufacturer’s recommendation (typically front to back and vice versa).
5. Reinstall tires and hand-tighten the lug nuts.
6. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 76 ft-lbs for Highlander).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use an alignment tool if available.
2. Adjust camber, toe, and caster angles to meet manufacturer specifications.
3. Confirm the alignment is within acceptable ranges using alignment equipment.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect control arms and bushings for cracks or excessive wear.
2. Check shock absorbers for leaks or failure.
3. Replace any worn or damaged suspension components using appropriate tools such as a socket set.
4. Recheck alignment after any suspension repairs.
