jimborokz,

My puck system is "tight" but hasn't (yet) stuck or jammed the pins. I use a wire brush and clean the puck seats every spring, then spray them with some penetrating oil, let that sit overnight, then clean that out with some 409.

As for the puck "pins", I spray them with penetrating oil and let that sit overnight also. I don't clean the pins, I leave that little bit of oil on them. So far, I haven't had any dirt/grime buildup on the pins.

My hitch (probably yours too) has castellated nuts with cotter pins to adjust the hitch "tightness" in the puck seats. If they're too loose, the hitch rattles, if too tight, the hitch locking arms bind when installing the hitch. There's a "fine line" between too tight and too loose.

On my hitch, if I position it in the pin seats unevenly, it will bind, but just lifting it an inch or so on the low side, it's always "just slipped into the seats.
