* Strut Mounts (Top Mounts): These are the rubber bushings at the top of the struts. Worn or damaged mounts can cause popping sounds, particularly when the suspension compresses and rebounds during turning and maneuvering. This is a very common cause of popping noises.
* Ball Joints: These connect the control arms to the steering knuckles. Worn ball joints can create popping or clicking sounds, especially when turning.
* Control Arm Bushings: Similar to strut mounts, worn bushings in the control arms can lead to popping noises as the suspension moves.
* Tie Rod Ends: These connect the steering rack to the wheels. Worn tie rod ends can cause clunking or popping sounds, especially during turning.
* Sway Bar Links/Bushings: These components help control body roll. Worn links or bushings can create popping sounds, particularly when cornering.
* CV Axles (less likely): While less likely to cause a popping sound specifically when turning the wheel while backing up, severely worn CV axles *could* contribute, especially if the popping is accompanied by other symptoms like vibrations.
Why it's unlikely to *only* be the struts: While worn struts can cause noises, they're more likely to produce a knocking or thudding sound over bumps, rather than a sharp popping sound specifically when turning the wheel. The popping is more indicative of something in the suspension system that's moving and binding under stress.
What to do:
You need a thorough inspection by a qualified mechanic. They can diagnose the exact source of the popping noise by carefully examining the suspension components. Don't delay, as driving with a faulty suspension can be dangerous. Ignoring the problem could lead to further damage or even an accident.
