Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off, and the keys removed.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Damaged Components

Control Arms and Bushings
- Remove the wheel on the side making the noise using a socket set.
- Inspect the control arm bushings for cracks or separation. If damaged, replace the control arm.
- Use a torque wrench to tighten the control arm bolts to the manufacturer's specifications.
CV Joints and Boots
- Check for torn or leaking CV boots. If boots are damaged, replace them along with the CV joint.
- To replace, remove the axle nut using a socket, then detach the CV joint from the wheel hub and replace it.
Steering Rack and Tie Rod Ends
- Inspect the tie rod ends for any signs of wear. If they are loose, replace them.
- To replace, remove the cotter pin and nut on the tie rod end, then disconnect it from the steering knuckle.

3. Reassemble and Test

Reassemble any components that were removed, ensuring all fasteners are torqued to specifications.
Reconnect the battery and perform a test drive to ensure the popping sound is resolved.
