Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the CV joints.
3. Visually inspect the CV boots for tears or leaks; replace if damaged.
4. If the CV joint is damaged, use a socket set to remove the axle nut and disconnect the CV joint from the hub.
5. Install the new CV joint by reversing the removal process, ensuring to torque the axle nut to the manufacturer specifications (typically 150 ft-lbs).

3. Replace Suspension Components if Necessary

Sub-steps:
1. Inspect control arms and bushings for damage; if found, remove the bolts securing the control arm using a socket set.
2. Replace with new components and torque to specified values (check manufacturer specifications).
3. Reattach any disconnected components and ensure proper alignment of the suspension.

4. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and check the fluid level.
2. If low, add the manufacturer-recommended power steering fluid until it reaches the correct level.

5. Test Drive

After all repairs, lower the vehicle and reconnect the battery.
Conduct a test drive to ensure the popping noise has been resolved.
