I have a banister post that can tilt toward the stairs. It is pretty sturdy when pushing away from the stairs. I have cut the carpet around it to try to see how it is attached, but cannot. On the stair side, there seems to be shims that may have been crushed or something, which is why it seems to be loose now. The only solid piece of wood near the post is on the stair side, that I can see when peering between the floor and post. Any ideas on how to fix it?
