Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warnings: Disconnect the battery before working on electrical components.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle on jack stands to prevent it from falling.

3. Inspect and Replace Components

Control Arms:
- Remove the bolts securing the control arms using a socket and ratchet.
- Inspect the bushings for wear; replace if cracked or torn.
- Install new control arms, ensuring the bolts are torqued to manufacturer specifications (usually around 50-60 Nm).
Sway Bar Links:
- Remove the sway bar links by unbolting them from their mounting points.
- Check for any play or excessive wear; replace if necessary.
- Install new sway bar links, tightening bolts to the specified torque (often around 30 Nm).
Struts/Shocks:
- If struts are suspected, remove the strut assembly by unbolting it from the top and bottom mounts.
- Inspect for leakage or damage; replace if needed.
- Reinstall struts, ensuring all bolts are properly torqued.

4. Reassemble and Lower Vehicle

Double-check all components are secure and properly installed.
Remove jack stands and lower the vehicle back to the ground using the hydraulic jack.

5. Test Drive

Conduct a test drive to ensure the popping noise has been resolved and that the suspension operates smoothly.
