Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and support it with jack stands.
Ensure the vehicle is stable before proceeding with repairs.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel to access the suspension components.

4. Inspect and Replace Components

A. Check Struts and Mounts

Inspect the strut assembly for any signs of leakage or damage.
If the strut is damaged, remove it by:
1. Disconnecting the brake line and any associated sensors.
2. Removing the bolts securing the strut to the knuckle and top mount.
3. Installing a new strut by reversing the removal steps and ensuring all bolts are torqued to the manufacturer's specifications.

B. Replace Worn Bushings

If bushings are worn, remove them using a bushing removal tool.
Clean the area where the new bushing will be installed.
Install new bushings by pressing them into place, ensuring they are correctly aligned.

5. Reassemble

Reattach the wheel and tighten lug nuts to the specified torque.
Lower the vehicle off the jack stands.

6. Test Drive

Conduct a test drive to confirm that the popping noise has been resolved.
