Should hitch mounted bike racks move or sway when traveling?
My current one (1.25", two bike trays with arms clamping on the tire) will sway and move when traveling with bikes on it.
During the weekend, I had a discussion about racks where the other person stated his didn't sway during traveling.
I had a closer look at my setup last night. The swaying comes from the hinge between the rack and the receiver tube. There is a bit of play there enabling the rack to move and sway.
The rack has a feature of being able to angle it away from the car in order to get access to the hatch, or to store it closer to the tail gate when not in use.
