I just installed my Hollywood HR1000 rack to a class II curt hitch. The fit isnt as tight as I originally expected, it seems to wobble a bunch, like it's not mated properly. Has anyone had this same issue? What type of racks do you have and how do you deal with this?

 

That rack looks just like this rack

which also looks just like the "Xport" rack i got from Performance Bicycle.

Mine is not wobbly however. Are you using an anti-rattle hitch pin or lock? Scroll to the bottom of my link to see what they are. Basically it's a long bolt that attaches your rack to your hitch instead of a mere pin. The bolt should allow you to tighten the rack nice and tight to the receiver to eliminate any play.
