I have kwikee (two steps) going into my 2005 motorhome. They work correctly. My problem is a friend of mine said he thought they are broken, he thinks because they move a little bit down when you step...
Up underneath your step assembly frame toward the back, there should be a bolt on both sides of the frame that retain an eccentric type cam. You can loosen the bolt and rotate the cam to a position where the downward movement of the steps can be minimized. Best when adjusting to have someone to put pressure on the steps while you make the adjustment. Anyway, that's the way it works on our Kwikee steps.
