Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace CV Joints

Raise the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the front wheel.
Inspect CV Joint: Check the CV joint for any damage or leaking grease.
Remove CV Axle: If damaged, remove the axle nut using a torque wrench. Then, disconnect the CV joint from the wheel hub and the transmission.
Replace CV Joint: Install the new CV joint and reattach the CV axle to the wheel hub and transmission.
Reinstall Wheel: Put the wheel back on and torque the lug nuts to the manufacturer’s specification.

3. Inspect and Tighten Suspension Components

Visual Inspection: Check all suspension components (control arms, bushings, struts) for any visible damage.
Tightening Bolts: Use a torque wrench to ensure all suspension and steering components are tightened to the specified torque settings.
Replace Worn Components: If any components are worn or damaged, replace them as necessary.

4. Test Drive

Lower the vehicle and reconnect the battery terminal.
Take the vehicle for a test drive to ensure the popping noise has been resolved.
