Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure it with jack stands to ensure safety while working underneath.

3. Inspect Suspension Components

Remove the wheel to gain access to the suspension.
Inspect control arms, struts, and bushings for wear and tear.
Check sway bar links for looseness or breakage.

4. Replace Damaged Components

If any components are found damaged, proceed to replace them:
- Sway Bar Links:
  1. Remove the nuts securing the sway bar link to the sway bar and control arm.
  2. Install the new sway bar link and torque to manufacturer specifications (typically around 35-40 ft-lbs).
- Struts/Shocks:
  1. Remove the strut assembly by unbolting it from the top and bottom mounts.
  2. Replace the strut with a new one, ensuring to torque the bolts to the manufacturer’s specification (usually around 50-75 ft-lbs).

5. Reassemble and Test

Reattach the wheel and lower the vehicle.
Test drive the vehicle over bumps to verify that the popping noise has been resolved.
