Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, OBD-II scanner, wrench set, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Replacement

Check Tread Depth:
- Use a tread depth gauge. Replace tires if tread depth is below 2/32 inch.
Check Tire Pressure:
- Use a tire pressure gauge to measure air pressure. Inflate tires to the recommended PSI listed on the driver's door jamb.
Replace Tires (if necessary):
- Loosen lug nuts, raise the vehicle with a jack, and secure it on stands.
- Remove lug nuts and take off the old tire. Install the new tire, hand-tighten lug nuts, and lower the vehicle. Torque lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

3. Suspension Inspection and Repair

Visual Inspection:
- Look for worn or damaged components such as shocks, struts, and bushings. Replace any damaged parts.
Alignment Check:
- If the suspension is intact but the vehicle still feels unstable, perform a wheel alignment using a professional alignment machine to ensure proper angles are set.

4. Traction Control System Check

Scan for Codes:
- Connect the OBD-II scanner and check for any fault codes. Address any issues indicated by codes (e.g., faulty wheel speed sensors).
Test System:
- Ensure that the traction control engages when slipping is detected. If not functioning, inspect and replace the traction control module if necessary.
