do what i did .Bought a piece of rubber hose and cut to exact specs worked for me .Cost $5.99.

 

What did you do with the hose? Did you just stick a piece in the opening between the receiver and ball mount and just take it out when you remove the mount?

I am hoping to find a more permanent solution. I might just buy a clamp...

I tried wrapping it in electrical tape and it is hard to slide in the reciever now and it still moves around in there.
