Solution

1. Preparation

Gather tools and materials required for inspection and repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Tire Inspection and Replacement

Check Tire Pressure
- Use a tire pressure gauge to check that all tires are inflated to the recommended PSI.
- Adjust tire pressures as necessary.
Examine Tread Depth
- Use a tread depth gauge to measure the tread on each tire.
- Replace any tires with tread depth below 2/32 of an inch.
Replace Tires (if needed)
- Loosen lug nuts using a socket set.
- Jack up the vehicle and secure it with jack stands.
- Remove the wheel and replace it with a new tire, ensuring proper alignment of the rim.
- Tighten lug nuts to the manufacturer’s specified torque (usually 80-100 ft-lbs).

3. Suspension Inspection and Repair

Visual Inspection
- Inspect the suspension components for signs of wear, such as leaking shocks, broken springs, or damaged bushings.
Replace Worn Components
- If any components are worn or damaged:
  - Remove the old part using the appropriate socket sizes.
  - Install the new part, ensuring it is seated correctly.
  - Torque bolts to the manufacturer’s specifications.

4. Traction Control System Check

Reconnect Battery
- Reconnect the battery and clear any diagnostic codes using the OBD-II scanner.
Test Traction Control
- Conduct a controlled test drive to ensure the traction control system engages properly during acceleration.
