Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and safety goggles.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and securely place it on jack stands.
Remove the wheel to access the suspension components.

3. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
- Inspect for oil leakage and physical damage.
- If damaged, remove the strut assembly by unbolting the top mount and lower bolts. Replace with new struts, ensuring proper torque specifications (typically 50-60 lb-ft for lower bolts and 20-25 lb-ft for top mount).
Sway Bar Links and Bushings:
- Remove the sway bar links by unbolting the nuts (usually 15-18 lb-ft).
- Replace with new links and bushings if worn, ensuring they are properly secured.

4. Reassemble

Reinstall the wheel, tightening the lug nuts to the manufacturer's specifications (usually 76-83 lb-ft).
Lower the vehicle from the jack stands and perform a final torque check on the lug nuts.

5. Test Drive

Take the vehicle for a test drive over bumps to ensure the popping noise has been resolved.
