Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace CV Joints

Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the front wheel.
Inspect CV Joint: Check the outer CV joint for torn boots or excessive play. If damaged, proceed to replace.
Remove CV Joint: Unbolt the CV joint from the wheel hub and the transmission side (if necessary) using appropriate tools.
Install New CV Joint: Apply grease to the new CV joint and install it back into place, ensuring it is securely attached to both the wheel hub and transmission.
Reinstall Wheel: Replace the wheel and tighten the lug nuts to the manufacturer’s torque specifications.

3. Inspect and Replace Sway Bar Links

Locate Sway Bar Links: With the vehicle still lifted, locate the sway bar links attached to the sway bar and the lower control arm.
Check for Wear: Inspect the sway bar bushings and links for cracking or excessive play.
Remove Old Links: If worn, use a socket set to unbolt and remove the old sway bar links.
Install New Links: Position the new sway bar links and tighten to the specified torque settings.
Lower the Vehicle: Remove the jack stands and lower the vehicle back to the ground.

4. Final Inspection

Check All Fasteners: Ensure all components are secure and that no tools are left under the vehicle.
Reconnect Battery: Reconnect the battery terminals securely.
Test Drive: Take the vehicle for a test drive to confirm the popping sound is resolved.
