Where the coupler sits on the ball of the truck and latches and unlatches is a spring. I believe it is to help assist with the release latch springing up upon unlatching. The very front pin slides thru the center of the spring. It became lodged and would not allow me to latch the trailer to the truck. I removed the pin to unlodge the spring, but not sure how the spring is reinstalled. A quick search of the parts diagram doesn’t list the spring. Anyone deal with this and could give me some insight?

Thanks
