Solution

1. Preparation

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

2. Tire Inspection and Replacement

Sub-steps:
1. Remove all four tires using a lug wrench.
2. Inspect each tire for uneven wear; replace if tread depth is below 2/32 of an inch.
3. Check tire pressure and inflate to the manufacturer's recommended PSI.
4. Reinstall tires and torque the lug nuts to the specified value (typically 76 ft-lbs for Highlander).

3. Suspension Component Replacement

Sub-steps:
1. If any struts or shocks show signs of leakage or wear, remove the old components using a socket set.
2. Install new struts/shocks, ensuring they are torqued to manufacturer specifications (e.g., 30 ft-lbs).
3. Replace any worn bushings or mounts to eliminate noise and improve ride quality.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure the alignment is adjusted to the manufacturer’s specifications.
3. Verify that all adjustments are properly documented.
