Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure. Inflate to the recommended PSI if necessary.
2. Measure tread depth using a tread depth gauge; replace tires if tread is below 2/32 inch.
3. If tires need replacing, use a jack to lift the vehicle and remove the wheel lug nuts with a socket set.
4. Replace with new tires, ensuring proper alignment of the rim, and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Traction Control and ABS Inspection

Sub-steps:
1. Locate the traction control and ABS module under the hood and inspect for damaged wiring or connectors.
2. If any wiring is damaged, splice in new wiring and ensure connections are secure.
3. Clear any error codes from the system using the OBD-II scanner.

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Visually inspect struts and shocks for leaks; replace if any fluid is present.
2. Check bushing integrity and replace any that are cracked or worn.
3. For strut replacement, remove the wheel, disconnect the strut from the lower control arm and top mount, and install the new strut, torquing bolts to the specified values.
