Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Remove the wheel using the socket set.
Use the pry bar to disconnect the CV joint from the wheel hub.
Inspect the CV joint for damage or excessive play.
If damaged, replace the CV joint assembly:
- Remove the axle nut with a socket.
- Pull the axle out of the transmission and replace with a new joint.
- Reinstall the axle and torque the nut to the manufacturer’s specifications (typically around 150 lb-ft).

3. Check and Replace Suspension Components

Tools Required: Wrench set, torque wrench, ball joint separator.
Inspect struts, control arms, and bushings for wear.
If any components are damaged:
- Remove the affected component using the wrench set.
- Replace with new parts and torque to manufacturer specifications.
- Ensure all bushings are properly seated.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Tighten the lug nuts to the specified torque (usually around 100 lb-ft).
Reconnect the battery.
Perform a test drive to ensure the popping noise has been resolved.
