Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a stethoscope (for noise diagnosis).
Ensure the vehicle is on a flat surface and secure it with jack stands after lifting with the jack.
Safety Warning: Always wear safety glasses and gloves when working under a vehicle.

2. Inspect Suspension Components

Sub-steps:
1. Remove the front wheels using a socket set.
2. Visually inspect the ball joints and control arms for signs of wear or cracks.
3. Use a pry bar to check for play in the bushings; replace if any movement is detected.

3. Check CV Joints and Boots

Sub-steps:
1. Inspect the CV joints for any signs of grease leakage or damage.
2. If the boots are torn, replace the entire CV axle assembly.
3. If the joints are damaged but the boots are intact, consider repacking and re-sealing.

4. Examine Steering Components

Sub-steps:
1. Inspect the steering rack for any signs of leaks or damaged mounting points.
2. Check the tie rod ends for wear; replace if there is excessive play.
3. Securely tighten any loose connections or components.

5. Evaluate Wheel Bearings

Sub-steps:
1. Spin the wheels by hand to check for roughness or noise.
2. If noise or play is detected, replace the wheel bearings as necessary.
3. Ensure proper lubrication and torque specifications during reinstallation.

6. Reassemble and Test

Sub-steps:
1. Reinstall the front wheels and torque the lug nuts to the manufacturer’s specifications.
2. Lower the vehicle and perform a test drive to verify the popping noise has been resolved.
