Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, tire pressure gauge, wheel balancer, alignment equipment.
Safety Warning: Ensure vehicle is on level ground and securely supported before working underneath.

2. Tire Inspection and Maintenance

Visual Inspection: Examine all tires for uneven wear, bulges, or foreign objects.
Check Tire Pressure: Use a tire pressure gauge to measure PSI. Inflate or deflate as necessary to match the manufacturer's recommended levels.
Rotate Tires: If uneven wear is noted, consider rotating the tires to promote even wear.

3. Wheel Balancing

Remove Wheels: Use a lug wrench to loosen and remove the lug nuts and take off the wheels.
Balance the Wheels: Place the wheels on a wheel balancer. Adjust weights as needed to ensure that each wheel is balanced.
Reinstall Wheels: Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs for F-150).

4. Suspension and Alignment Check

Inspect Suspension Components: Check for worn-out bushings, ball joints, or shocks. Replace any damaged components.
Perform Wheel Alignment: Use alignment equipment to adjust the camber, caster, and toe settings to manufacturer specifications.

5. Test Drive

After repairs, take the vehicle for a test drive to ensure the shaking has been resolved.
