Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during repairs.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear, bulges, or punctures.
- Measure tread depth using a tread depth gauge.
Replace Tires:
- If tread depth is below 2/32", remove the old tires using a tire iron.
- Install new tires, ensuring they are the correct size and type for the vehicle.
- Torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Traction Control System Check

Scan Traction Control:
- Reconnect the battery and use an OBD-II scanner to clear any error codes.
- Perform a test drive to see if warning lights reappear.
Inspect Wheel Speed Sensors:
- Remove the wheel to access the wheel speed sensors.
- Check sensor wiring for damage and clean the sensor if dirty.
- Reinstall the wheel and perform a test drive.

4. Suspension Inspection and Repair

Inspect Components:
- Check all suspension components (shocks, struts, bushings) for signs of wear or damage.
Replace Worn Parts:
- If any components are found to be faulty, remove them using appropriate tools (e.g., socket set).
- Install new parts according to the service manual specifications.
- Torque all fasteners to the recommended specifications.
