Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, and wheel balance weights.
Ensure the vehicle is parked on a level surface and turn off the ignition.

2. Tire Balancing

Remove the wheels from the vehicle using a jack and jack stands.
Take the wheels to a tire shop for professional balancing or use a DIY balancer if available.
Reattach the wheels using a torque wrench to ensure lug nuts are tightened to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Tire Inspection and Replacement

Check all tires for uneven wear, bulges, or cracks.
If any tire shows significant wear or damage, replace it with a new tire that matches the specifications for the F-150.
Ensure that the replacement tires are properly inflated according to the vehicle’s specifications (usually found in the owner’s manual or door jamb).

4. Wheel Alignment

Take the vehicle to a professional alignment shop to check and adjust the alignment.
Request a full four-wheel alignment to ensure all wheels are aligned correctly.

5. Suspension Check

Inspect suspension components visually for wear, especially bushings and shock absorbers.
Replace any components that show signs of wear or damage with OEM or high-quality aftermarket parts.
Ensure all bolts and nuts are torqued to factory specifications.

6. Driveshaft and U-Joint Inspection

Inspect the driveshaft for any signs of bending or damage.
Check U-joints for looseness or play; replace if necessary.
Reinstall any components and ensure they are properly torqued.
