Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Check Tire Pressure
- Use a tire pressure gauge to measure the pressure of all four tires.
- Inflate tires to the recommended PSI as stated on the driver's door jamb.
Inspect Tire Condition
- Look for cracks, bulges, or other visible damage.
- Assess tread depth using a tread depth gauge; replace tires if tread is below 2/32 inches.

3. Suspension Inspection and Repair

Visual Inspection
- Check for leaks in shock absorbers or struts; replace if necessary.
- Inspect bushings and control arms for wear or damage.
Replace Components
- If any components are found damaged, replace them with OEM or high-quality aftermarket parts.
- Ensure all bolts are torqued to manufacturer specifications.

4. Wheel Alignment

Alignment Check
- Take the vehicle to a professional for a four-wheel alignment check.
- Adjust as needed to manufacturer specifications.

5. Brake System Inspection and Repair

Inspect Brake Components
- Check for uneven wear on brake pads and rotors.
- Replace any worn components and ensure calipers operate freely.

6. Traction Control System Check

Scan for Errors
- Use an OBD-II scanner to check for traction control system errors.
- Clear any codes and test drive the vehicle to verify proper function.
