Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised on jack stands.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint grease, and a new CV joint if necessary.
Remove the wheel on the side where the popping noise is heard.
Inspect the CV joint boot for tears or leaks. If damaged, proceed to replace the CV joint.
Use a socket set to remove the axle nut and disconnect the CV joint from the hub.
Pull the CV axle out of the transmission and replace with the new part. Make sure to apply new CV joint grease.

3. Check and Replace Suspension Components

Inspect the tie rods and ball joints for any signs of wear or damage.
If any components are worn, remove and replace them as follows:
- Use a socket set to loosen and remove the nuts and bolts securing the tie rod or ball joint.
- Install the new component, ensuring it is torqued to the manufacturer's specifications.
- Reattach any removed components.

4. Reassemble and Lower Vehicle

Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
Lower the vehicle back to the ground.
