Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shock Absorbers

Remove the Wheel:
- Use a jack to lift the rear of the vehicle and secure it with jack stands.
- Remove the rear wheel using a socket set.
Remove Shock Absorber:
- Locate the top and bottom mounting bolts on the shock absorber.
- Use a socket wrench to remove the top bolt first, then the bottom bolt.
- Carefully remove the shock absorber from its mounting position.
Install New Shock Absorber:
- Position the new shock absorber in place.
- Reinstall the bottom bolt first, followed by the top bolt.
- Torque the bolts to the manufacturer's specifications (typically around 40-50 ft-lbs).

3. Inspect and Replace Sway Bar Links

Locate Sway Bar Links:
- With the wheel still removed, locate the sway bar links connected to the sway bar and suspension.
Remove Old Links:
- Use a wrench to hold the sway bar link in place while loosening the nut with a socket wrench.
- Remove the link from both the sway bar and the lower control arm.
Install New Links:
- Position the new sway bar links in place and secure them with nuts.
- Torque to specifications (typically around 35 ft-lbs).

4. Reassemble and Test

Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value (typically 75-85 ft-lbs).
Test Drive:
- Take the vehicle for a test drive to ensure the popping noise has been resolved.
