Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Damaged Components

Suspension Inspection:
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access suspension components.
- Inspect control arms, bushings, and struts for any signs of wear or damage.
- Replace any damaged components with OEM parts; torque specifications should follow manufacturer guidelines.
Drivetrain Check:
- Inspect the CV joints and axles for any signs of wear or tearing.
- If CV joints are damaged, remove the affected axle:
  - Remove the axle nut using a socket wrench.
  - Disconnect the lower control arm to free the axle.
  - Replace the CV joint or axle with a new part, ensuring proper torque on the axle nut.

3. Reassemble and Test

Reattach the wheel and lower the vehicle back to the ground.
Reconnect the battery and perform a test drive to ensure the popping noise has been resolved.
