Thanks Uwe.

Then the simple answer that seems to be correct, is that we need to replace the GM OEM hitch if we want this to go away.

I had installed a Reese receiver hitch on my Impala SS back when I first got the Bambi. My hitch bar (left picture) did fit and still does fit snug in that receiver.

Same hitch bar inserted into my Suburban's OEM hitch has play.

I did happen to look at a new 3/4 ton Suburban (post 2006 model) a few days ago...it appears GM has gone back to the receiver area not being outside the rest of the hitch as found in our gen OEM hitches.
