Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Inspect Tires:
- Check tire pressure with a tire gauge; inflate to manufacturer's specifications.
- Measure tread depth; replace tires if below 2/32 inches.
Replace Tires (if necessary):
- Lift the vehicle with a jack and secure with jack stands.
- Remove the wheel lug nuts using a socket set and remove the tire.
- Install new tires and torque lug nuts to the manufacturer’s specifications (typically 76 lb-ft).

3. Suspension Component Inspection

Visual Inspection:
- Check for damaged or worn suspension components (struts, bushings).
- Look for any leaks in shock absorbers.
Replace Worn Components:
- Remove any damaged components using appropriate tools (e.g., socket set).
- Install new parts, tightening to the manufacturer’s specifications.

4. Traction Control System Check

System Check:
- Use an OBD-II scanner to read and clear any fault codes related to the traction control system.
- Test the system by driving the vehicle in a controlled environment to ensure proper operation.

5. Wheel Alignment and Balancing

Alignment Inspection:
- Take the vehicle to a professional for a four-wheel alignment check.
- Ensure that the alignment settings are within manufacturer specifications.
