Andersen Ultimate hitch movement

[occer]

I’ve mounted a used Andersen rail system for our new 5.0.

There is forward / backward movement between the Ball & Kingpin Coupler Block. It does not fit tight like a traditional reliever hitch ball and trailer coupler.
Is this normal and is there a way to reduce the movement ?

The coupler block-to-ball interface should be no more loose than any hitch>ball interface (very little 'slop').

You should see a red or black hard-plastic 'cup' inside the coupler block that the ball bears upon when hitched; a few folks have reported that 'cup' falling-out of the coupler block. Suggest you check to verify that plastic 'cup' is in place, its absence will result in lots of 'slop' in that interface.

Good Luck.

The movement is a combination of movement / flex in the whole system.

I set up my phone to take a video of the movement, the movement is in the whole system.
The base is flexing some, the ball is flexing in the base and the coupler has a very small amount of back & forth. Because it was just a drive around the block and under 10 mph there is no up / down movement between the ball and king pin adaptor.

The video put my mind at ease that there is not a problem and I found after few hundred more miles I don’t notice the movement.

The installation manual from Andersen states that the system can articulate up to 15 degrees. I believe a certain amount of flex/movement is desirable to avoid a jerky or bouncy ride...
