Solution

1. Preparation

Gather tools: jack, jack stands, tire iron, torque wrench, OBD-II scanner, and a tire balancing machine.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.

2. Tire Inspection and Balancing

Sub-step 1: Remove the wheel covers or hubcaps if equipped.
Sub-step 2: Loosen the lug nuts slightly while the vehicle is on the ground.
Sub-step 3: Lift the vehicle using a jack and securely place jack stands under the vehicle.
Sub-step 4: Remove the wheels completely.
Sub-step 5: Inspect tires for damage, uneven wear, or bulges. Replace any damaged tires.
Sub-step 6: Balance the tires using a tire balancing machine. Ensure all tires are within acceptable balance specifications before reinstalling.

3. Suspension and Wheel Bearing Inspection

Sub-step 1: While the wheels are off, visually inspect shocks and struts for leaks or physical damage.
Sub-step 2: Check control arms and bushings for signs of wear or damage; replace if necessary.
Sub-step 3: Grasp the wheel at 12 and 6 o’clock positions and check for play, indicating worn wheel bearings; replace if play is detected.
Sub-step 4: Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 140 ft-lbs for F-150).

4. Driveshaft and CV Joint Inspection

Sub-step 1: Inspect the driveshaft for any signs of damage, such as dents or cracks.
Sub-step 2: Check the CV joints for torn boots or excessive play; replace if damaged.
Sub-step 3: If necessary, realign or replace any damaged driveshaft components.
