SMA Rear Tire Carrier Issue

[PARAGON]

You've got to pump some grease in there from time to time. I've had mine for about a year and a half and the problems I had were more with a rattle (they have fixed this issue) and getting it lined up just right so that it opened and closed smoothly with no dragging on the little bushing.

If you're talking about the pin, it can be an alignment issue as well.
