Holland Simplex 5th wheel play

I have play in my 5th wheel when you take a pry bar and go to either side and pry up. I also can see movement front to back on the rails.

I assume the front to back movement is the slots it's in are worn but I cant get it to release to move it to another spot to confirm.

I really don't like this 5th wheel setup but Freightliner told me to convert to a jost or fontaine the whole assembly needs to be changed out. If I don't slam this thing into the king pin the release handle doesn't fully retract and it doesn't lock completely. I'm tired of slamming my truck into trailers.

For now I'm thinking just a rebuild of the pins and bushings to remove the side to side play and if the springs and jaws need done I'll do that as well.

Does anyone know if Holland makes a better setup that is compatible with the same rails and release setup that the Simplex uses? I don't want to spend money twice. Thanks

 

Thank you
