I have another Zieman trailer question. Sorry I am not familiar with the correct terms. My winch is bolted to a plate that is welded to a square post that slides into a female post that is welded to the main frame of the trailer. The plate and post used to fit snug now they wiggle quite severly (the male post inside the female) I recently changed the saftey chain and removed the bolt so figure I screwed somthing up but am unsure what. You can see in the picture that I can easily lift up the plate now. You couldn't before. Any ideas how these to secure these pieces?
