Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.
Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to gain access to the suspension components.
3. Visually inspect the struts, shocks, and bushings for signs of wear or damage.
4. If any components are damaged, remove the old parts using a socket set.
5. Install new suspension components according to manufacturer specifications, ensuring proper torque values are applied (typically 60-80 lb-ft for bolts).

3. Inspect and Replace Drivetrain Components

Sub-steps:
1. Check the condition of CV joints and axles for any signs of wear or tears in the boots.
2. If CV joints are damaged, remove the axle using a socket set and replace with new parts.
3. Reinstall the axle and torque the bolts to the manufacturer's specifications.

4. Reassemble and Test

Sub-steps:
1. Reattach the wheel and tighten lug nuts to the recommended torque (usually 80-100 lb-ft).
2. Lower the vehicle from the jack stands.
3. Reconnect the battery and start the vehicle.
4. Take the vehicle for a test drive to confirm that the popping noise has been resolved.
