Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the 12V battery for safety.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings
- Remove the front wheel using a socket set.
- Visually inspect control arms for cracks and bushings for wear.
- If damaged, proceed to replace the control arm.
Replace Control Arm (if needed)
- Remove the control arm bolts using a torque wrench (typically 50-60 lb-ft).
- Replace the control arm bushings if they are worn.
- Install the new control arm, ensuring proper alignment with bolt holes.
- Torque the control arm bolts to manufacturer specifications.

3. Inspect and Replace Struts or Shocks

Check Struts/Shocks for Leaks
- With the wheel still removed, inspect the struts for oil leaks.
- If leaking, remove the strut assembly.
Replace Strut Assembly
- Use a spring compressor to safely compress the spring on the strut.
- Detach the strut from the vehicle.
- Install the new strut assembly and reattach it to the vehicle.
- Ensure all bolts are torqued to specifications.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Perform a test drive to ensure the popping noise has been eliminated.
