On my premium, the screws loosened up on the bridge plastics that keep the ball from falling off. One plastic fell off, which is how I learned about this. When I investigated, all had become loose.
The front screws are easy to reach, but the back ones were not at all. I had to take a lot of the bridge apart and put it back correctly as far as I know. I am having an issue though where the bridge pieces will not sit flush on occasion and the ball will be trapped. It will clear with a ball search, but this is not ideal, especially with it on location.
Can anyone offer suggestions as to what I might have done to cause this? The assembly is fairly simple and each stack of hardware and the spacer is assembled the same as far as I noticed. I’m wondering if I have something too tight, or maybe even too loose. I don’t think I mixed up any of the spacers, I did at first but noticed the error and swapped them back so it all went together pretty much as expected.
