Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair process (if working on electrical components).

2. Raise the Vehicle

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

3. Inspect and Replace Suspension Components

Check Sway Bar Links:
- Remove the sway bar links using a socket set.
- Inspect for play or wear; replace if necessary.
Examine Bushings:
- Inspect control arm and sway bar bushings for cracks or deterioration.
- Replace worn bushings with new ones.
Inspect Struts/Shocks:
- Check for oil leakage or damage.
- If faulty, remove the strut assembly and replace with a new one, ensuring proper alignment and torque specifications.

4. Reassemble and Lower Vehicle

Reinstall all components in reverse order of removal, ensuring all bolts are torqued to manufacturer specifications.
Reattach the wheels and lower the vehicle back to the ground.

5. Final Check

Reconnect the battery and perform a visual inspection to ensure all components are secure.
Test drive the vehicle to confirm the popping noise is resolved.
