Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect Suspension Components

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure with jack stands.
2. Remove the front wheels to gain access to the suspension.
3. Visually inspect the struts and shocks for any signs of leaks or physical damage.
4. Check control arms and bushings for cracks or excessive wear.
5. Tighten any loose bolts or fasteners associated with the suspension.

3. Check Exhaust System

Sub-steps:
1. Inspect the exhaust system from the engine to the tailpipe for any loose hangers or broken mounts.
2. Look for any signs of rust or damage on the exhaust pipes.
3. If any components are loose, replace hangers or tighten brackets as necessary.

4. Examine Wheel Wells

Sub-steps:
1. Check the wheel wells for any debris, stones, or foreign objects lodged in the suspension.
2. Remove any objects that could be causing the popping sound.

5. Tire Inspection

Sub-steps:
