2. Inspect each tire for proper inflation using a tire pressure gauge.
3. Look for bulges, cracks, or any signs of damage.
Tools Required: Tire pressure gauge

2. Wheel Balancing

Sub-steps:
1. Remove each wheel from the vehicle.
2. Take the wheels to a tire shop for balancing.
3. Have weights adjusted or added as needed.
4. Reinstall the wheels securely, ensuring proper torque specifications are met (typically 100-150 ft-lbs for F-150).
Tools Required: Torque wrench

3. Suspension Component Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect control arms, bushings, and struts for any signs of wear or damage.
3. If any components are damaged, replace them with OEM or high-quality aftermarket parts.
4. Reassemble and lower the vehicle back to the ground.
Tools Required: Jack, jack stands, socket set

4. Driveshaft Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
