Fifth wheel Hitch troubleshooting

I have a different hitch but have the same issue if I have the nose of the trailer too high. I walk that fine line of having it low enough that the kingpin slides up the hitch without it feeling like I am jamming the hitch onto the kingpin causing the trailer getting knocked around a bit. (that is an over simplified explanation). I know I am not hitting it hard or anything, it just feels wrong to have it jar the trailer.

I also think you may want to try to check the lubrication. Could be a combination of both things---too high and too dry. Let us know your outcome.
