Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to ensure safety.

2. Inspect Suspension Components

Lift the vehicle using a hydraulic jack and support it on jack stands.
Remove the front wheels using a socket set.
Inspect control arms, bushings, and struts for any signs of wear, cracks, or damage.
Replace any worn components with OEM parts.

3. Inspect CV Joints

Examine the CV joints for torn boots or grease leakage.
If damaged, remove the axle using a socket set and replace the CV joint or the entire axle assembly.
Ensure proper installation and torque the axle nut to manufacturer specifications (usually around 250 Nm).

4. Check Power Steering System

Inspect the power steering fluid reservoir for proper fluid level.
If low, top off with the manufacturer-recommended fluid.
Check for any leaks in the power steering lines or the pump.

5. Reassemble and Test

Reinstall the front wheels and lower the vehicle.
Reconnect the battery.
Test drive the vehicle to ensure the popping sound is resolved.
