Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Sway Bar Links

Tools Required: Socket set, torque wrench, penetrating oil
Sub-steps:
1. Locate the sway bar links on both sides of the front suspension.
2. Apply penetrating oil to the bolts if they are rusted or difficult to remove.
3. Using the socket set, remove the bolts securing the sway bar links.
4. Replace with new sway bar links, ensuring they are aligned correctly.
5. Torque to manufacturer specifications (typically around 40-50 ft-lbs).

3. Inspect and Replace Strut Assembly (if necessary)

Tools Required: Jack and jack stands, strut spring compressor, socket set, torque wrench
Sub-steps:
1. Raise the front of the vehicle and secure it with jack stands.
2. Remove the wheel to gain access to the strut assembly.
3. Disconnect any brake lines or sensors attached to the strut.
4. Remove the strut assembly by unscrewing the top and bottom mounting bolts.
5. If the strut is faulty, use a strut spring compressor to remove the spring and transfer it to a new strut.
6. Install the new strut assembly, ensuring all bolts are torqued to specifications.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and lower the vehicle back to the ground.
2. Reconnect the battery.
3. Perform a test drive to ensure the popping noise has been resolved.
