Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if necessary to prevent electrical issues.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, tire iron
Check the tire pressure using the gauge and inflate to the manufacturer's recommended PSI if needed.
Inspect the tires for signs of uneven wear or damage; replace if necessary.

3. Wheel Alignment and Balancing

Tools Required: Wheel alignment machine
Take the vehicle to a professional shop for a wheel alignment and balancing service.
Adjust the alignment settings to manufacturer specifications.

4. Drivetrain Component Inspection

Tools Required: Jack and jack stands, socket set
