Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, stethoscope.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool if it has been recently driven.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle on jack stands to ensure stability while working underneath.

3. Inspect and Replace Suspension Components

Inspect Struts and Shocks:
- Check for leaks or damage on struts and shocks.
- If damaged, remove the strut assembly by loosening the bolts and replacing it with a new unit.
- Torque bolts to manufacturer specifications (usually around 37-50 ft-lbs for strut bolts).
Inspect Sway Bar Links:
- If the sway bar links show signs of wear, remove the old links using a socket set.
- Install new sway bar links and torque to specifications (approximately 15-20 ft-lbs).
Inspect Bushings:
- Check all bushings for cracks or wear.
- Replace any worn bushings as necessary. This may require pressing out old bushings and pressing in new ones.

4. Reassemble and Lower the Vehicle

Ensure all bolts are tightened to the correct torque specifications.
Remove jack stands and lower the vehicle back to the ground with the jack.

5. Test Drive

Take the vehicle for a test drive over bumps to verify that the popping noise has been resolved.
