Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, torque wrench, CV joint replacement kit.
Lift the vehicle and secure it on jack stands.
Remove the wheel to access the CV joint.
Inspect the CV joint boot for tears or grease leakage.
If damaged, remove the CV joint from the axle by unscrewing the retaining nut and disconnecting any clips.
Install the new CV joint by reversing the removal process, ensuring to properly torque the retaining nut to manufacturer specifications (typically around 120 ft-lbs).

3. Replace Worn Suspension Components

Tools Required: Jack, jack stands, socket set, torque wrench, suspension component kit.
Identify any worn or damaged components during the visual inspection.
Remove the affected component (e.g., control arms, bushings, or ball joints) by unbolting them from their mounting points.
Install the new components, ensuring all bolts are torqued to the manufacturer's specifications.
Reassemble any related components and reinstall the wheel.

4. Test Drive

Lower the vehicle back to the ground.
Reconnect the battery if it was disconnected.
Conduct a test drive to confirm the resolution of the popping noise.
