Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and check the fluid level.
2. If low, top off with manufacturer-recommended fluid (e.g., Mercon ATF for many Ford models).
3. If fluid is dark or contaminated, perform a fluid flush.

3. Inspect and Replace CV Joints (if damaged)

Sub-steps:
1. Raise the front of the vehicle and secure it on jack stands.
2. Remove the wheel to access the CV joint.
3. Inspect the boot for tears and the joint for wear.
4. If damaged, remove the axle nut and disconnect the CV joint from the hub.
5. Install the new CV joint, ensuring proper torque on the axle nut (typically 150-200 ft-lbs).

4. Check and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Remove the wheel and brake caliper to expose the hub assembly.
2. Check for play in the wheel bearing by wiggling the hub.
3. If loose or rough, remove the hub and bearing assembly.
4. Install new bearings, ensuring they are properly seated and greased.

5. Inspect and Replace Suspension Components (if damaged)

Sub-steps:
1. Visually inspect control arms, bushings, and other suspension components.
2. If any components are worn or damaged, remove and replace them.
3. Torque all bolts to the manufacturer’s specifications.
