Solution

1. Preparation

Gather all necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Tire Inspection and Replacement

Sub-steps:
- Remove the wheel covers or hubcaps if present using a flathead screwdriver.
- Loosen the lug nuts using a lug wrench but do not remove them completely.
- Elevate the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheels.
- Inspect each tire for uneven wear, bulges, or foreign objects.
- If tires are worn, replace them with new ones, ensuring they match the specifications for the F-150.
- Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 100-150 ft-lbs).

3. Wheel Balancing

Sub-steps:
- Mount the tire on a wheel balancer.
- Spin the tire and identify any imbalances.
- Add wheel weights as needed to balance the tire.
- Reinstall the balanced tires on the vehicle.

4. Alignment Adjustment

Sub-steps:
- Use an alignment machine to check the alignment settings.
- Adjust the camber, caster, and toe angles to factory specifications.
- Test drive the vehicle to ensure proper alignment.

5. Suspension Component Inspection and Replacement

Sub-steps:
- Inspect all suspension components visually for signs of wear.
- Use a pry bar to check for excessive movement in bushings and joints.
- Replace any worn or damaged parts with OEM or quality aftermarket components.
- Reassemble and torque all components to specifications.
