Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow it to cool if it's been recently running.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Visually check for cracks or excessive wear.
- If damaged, remove the control arm by unbolting it from the chassis and the steering knuckle.
- Replace with new parts and torque bolts to manufacturer's specifications.
Replace Struts (if needed):
- Remove the wheel to access the strut assembly.
- Detach the strut from the knuckle and the chassis.
- Replace with a new strut and ensure proper alignment.

3. Examine and Replace CV Joints

Inspect CV Joints and Boots:
- Check for torn or leaking CV boots.
- If damaged, remove the axle from the differential and replace the CV joint or the entire axle assembly, ensuring proper torque on all fasteners.

4. Check Wheel Bearings

Inspect Wheel Bearings:
- Remove the wheel and brake assembly.
- Check for excessive play in the wheel bearing by turning the hub.
- If worn, replace the wheel bearings and seals.

5. Final Assembly and Test

Reassemble all components in reverse order of disassembly.
Ensure all bolts are torqued to specification.
Reinstall the wheels and lower the vehicle.
Test drive to confirm that the popping noise has been resolved.
