Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repairs.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the suspension components.

3. Inspect and Replace Suspension Components

Sway Bar Links:
- Check the sway bar links for wear or damage.
- If damaged, remove the nut using a socket wrench, replace the link, and torque to manufacturer specifications (typically around 30 Nm).
Strut Mounts:
- Inspect strut mounts for cracks or excessive wear.
- If replacement is needed, remove the strut assembly and replace the mount.
- Torque the strut mount bolts to the manufacturer's specified torque (usually around 25 Nm).
Control Arms:
- Inspect control arms for cracks or bushings for deterioration.
- If replacement is necessary, remove the control arm bolts, replace the control arm, and torque bolts to specifications (typically around 50 Nm).

4. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Reconnect the battery.

5. Test Drive

Conduct a test drive to ensure the popping noise has been resolved and the suspension is functioning correctly.
