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.

2. Tire Inspection and Replacement

Inspect Tires:
- Check tread depth using a tread depth gauge; replace if worn below 2/32 inches.
- Look for uneven wear patterns indicating alignment or suspension issues.
Replace Tires if Necessary:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and ensure it's securely supported.
3. Remove the lug nuts and take off the tire.
4. Install the new tire, ensuring it is mounted correctly according to the directional arrows.
5. Hand-tighten the lug nuts and lower the vehicle back to the ground.
6. Torque the lug nuts to the manufacturer’s specifications (usually around 100-120 ft-lbs).

3. Traction Control System Check

Reset the Traction Control System:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any fault codes in the traction control system.
3. Test drive to ensure the system is functioning properly.

4. Suspension and Brake Inspection

Inspect Suspension Components:
1. Visually inspect shocks, struts, and control arms for any signs of wear or damage.
2. Replace any worn components using appropriate torque specifications for fasteners.
Check Brake System:
1. Inspect brake pads and rotors for wear; replace as necessary.
2. Ensure brake calipers are functioning correctly and not seizing.
