Hope it comes out instead of snapping.

It's far more likely the cause. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
