Solution

1. Preparation

Gather tools and materials: jack, jack stands, lug wrench, dial indicator, brake cleaner, torque wrench, and replacement parts as necessary.
Ensure the vehicle is on a level surface and the engine is off.

2. Raise the Vehicle

Use a jack to lift the front or rear of the F-150, depending on where the shaking occurs.
Secure the vehicle with jack stands to prevent movement.

3. Inspect and Replace Brake Components

A. Brake Rotors

Remove the wheel using a lug wrench.
Inspect the brake rotor for warping using a dial indicator.
If warped beyond specifications, replace the rotor.
Clean the new rotor with brake cleaner before installation.
Reinstall the rotor and torque bolts to manufacturer specifications.

B. Brake Pads

Remove the caliper by loosening the caliper bolts.
Inspect brake pads for uneven wear or contamination.
If necessary, replace the brake pads.
Apply brake grease to the back of the pads to reduce noise.
Reinstall the caliper and torque bolts to manufacturer specifications.

4. Inspect Suspension and Alignment

Examine suspension components such as control arms and bushings for wear or damage.
Replace any worn or damaged suspension parts.
Perform a wheel alignment if necessary to ensure proper tracking.

5. Verify Tire Condition and Balance

Inspect tires for uneven wear patterns.
Check tire pressure and inflate to the recommended levels.
Have tires balanced and rotated if needed.
