Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Worn Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel on the affected side to gain access to the suspension components.
3. Inspect the strut, shock absorber, and springs for any visible damage or leaks.
4. Check the sway bar links and bushings for any signs of wear.
5. If any components are damaged, replace them with OEM or quality aftermarket parts.
6. Reassemble the suspension components and torque bolts to manufacturer's specifications (usually around 60-80 lb-ft for strut bolts).

3. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer's specifications (usually around 90-110 lb-ft).
4. Perform the same inspection on the opposite side if necessary.

4. Final Check

Sub-steps:
1. Test drive the vehicle over bumps to ensure the popping noise is resolved.
2. Recheck for any loose parts or noise after the test drive.
