A 2 inch step-mount and/or a 2 inch ball mount into a 2 inch receiver will have some normal "play". So will the others...1 1/4 and 2 1/2 inch varieties.

 

Same on my 2011. I put some black Gorilla brand tape around the end of the shaft and start of the shaft to eliminate it. I've had it like this for about 1 1/2 years and I don't see any deterioration of the tape so far. It still just slightly wiggles but more importantly it no longer makes thumping noises is it makes contact with the receiver.

 

thats a good idea, i'll try that this weekend. thanks for the tips guys.
