Solution

1. Preparation

Gather tools and parts needed for the repair.
Safety gear: gloves and safety glasses.
Park the vehicle on a flat surface, engage the parking brake, and use wheel chocks.

2. Inspect and Replace CV Joint

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel on the side where the popping noise is occurring using a socket set.
3. Inspect the CV joint boot for cracks or tears. If damaged, proceed to replace the CV joint.
4. Remove the axle nut using a socket and breaker bar.
5. Disconnect the lower control arm from the knuckle if needed to free the axle.
6. Pull the axle out of the transmission gently and remove it from the vehicle.
7. Install the new CV joint by reversing the removal steps, ensuring the boot is properly seated and lubricated.

3. Inspect and Replace Suspension Components

Sub-steps:
1. Check the condition of the struts, control arms, and bushings.
2. If any components show signs of wear, replace them as necessary.
3. Remove the damaged component using a socket set and pry bar if needed.
4. Install the new component, following manufacturer torque specifications for all bolts.
5. Reassemble any disassembled parts and ensure everything is tightened to specifications.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and lower the vehicle back to the ground.
2. Tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specifications.
3. Remove wheel chocks and test drive the vehicle to ensure the noise is eliminated.
