Solution

1. Preparation

Gather tools and parts.
Safety gear: gloves and safety glasses.
Ensure the vehicle is on a level surface and engage the parking brake.

2. Tire Inspection and Adjustment

Check each tire for visible damage (cracks, bulges).
Measure tire pressure with a tire gauge; adjust to manufacturer specifications (typically found on the driver's door jamb).
If any tire shows uneven wear, consider rotating the tires or replacing them if necessary.

3. Wheel Balancing

Remove the wheel and tire assembly from the vehicle using a socket set.
Mount the wheel on a wheel balancer.
Adjust weights as indicated by the balancer to achieve proper balance.
Reinstall the wheel, ensuring the lug nuts are torqued to the manufacturer's specifications (usually around 100-150 lb-ft for F-150).

4. Suspension Component Inspection

Visually inspect shocks/struts for leaks or damage.
Use a pry bar to check for play in control arms and bushings.
Replace any worn components as necessary, following manufacturer guidelines for installation.

5. Driveshaft and U-joint Inspection

Inspect the driveshaft for signs of wear or damage.
Check U-joints for play by moving them up and down; replace any faulty U-joints.
If the driveshaft is damaged, replace it following the manufacturer's specifications.

6. Wheel Alignment

After replacing or adjusting components, take the vehicle to a professional alignment shop.
Ensure the alignment is adjusted to the manufacturer's specifications.
