Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, OBD-II scanner, flashlight.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting the car.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir under the hood.
2. Check the fluid level; if low, top it off with the manufacturer-recommended power steering fluid.
3. If the fluid is dark or contaminated, drain and replace it with new fluid.

3. Inspect Steering Components

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Visually inspect the tie rods and ball joints for any signs of damage or wear.
3. If any components are damaged, proceed to remove and replace them.
  - For tie rods:
    - Loosen the lock nut with a wrench.
    - Use a tie rod puller to detach the tie rod from the steering knuckle.
    - Install a new tie rod and tighten the lock nut to the manufacturer's torque specification (check service manual).
  - For ball joints:
    - Remove the wheel and brake assembly as necessary.
    - Use a ball joint separator to detach the ball joint from the control arm.
    - Install the new ball joint and secure it to the control arm.

4. Inspect Suspension Components

Sub-steps:
1. Check the condition of the struts and control arms for any signs of wear or looseness.
2. Replace any worn out suspension components as necessary.
3. Reassemble any parts removed during inspection and ensure all nuts and bolts are tightened to the correct torque.

5. Final Assembly and Testing

Sub-steps:
1. Reinstall the wheel and lower the vehicle back to the ground.
2. Test drive the vehicle to ensure the popping sound is resolved.
3. Monitor the steering feel and check for any additional noises.
