Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and glasses.

2. Inspect and Replace Shocks/Struts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the affected corner to access the shock/strut assembly.
3. Inspect the shock/strut for any leaks or physical damage.
4. If replacement is necessary, unbolt the top mount inside the engine compartment and the bottom mount attached to the lower control arm.
5. Install the new shock/strut and torque the bolts to manufacturer specifications (typically around 30-50 lb-ft for top mounts and 70-90 lb-ft for bottom mounts).
6. Reinstall the wheel and lower the vehicle.

3. Wheel Alignment

Sub-steps:
1. After replacing shocks/struts, take the vehicle to a professional alignment shop.
2. Ensure that the alignment specifications are within Ford’s recommended values.
3. Adjust camber, caster, and toe angles as necessary.

4. Tire Balancing and Replacement

Sub-steps:
1. Inspect the tires for signs of damage or uneven wear.
2. If tires are worn out, replace them with new ones of the same specifications.
3. Have all four tires balanced at a tire shop to ensure optimal performance.
