The clutch is supposed to ratchet when it hits something, like an obstruction or the end of travel to protect the gear box.
First, check underneath the slide box inside the camper, assuming it is a Lippert above floor slide. Maybe some obstruction, construction debris, grand kid debris. Take a good look, gears engaging the track, rollers look good, no varmints, etc. use the dry lub while there.
Second, lub the slide seals. If the seals get hard and do not want to flip, this will cause undue drag and may cause the clutch to ratchet. Lub both the inside and outside flappers.
I hope it is something simple. Let us know what you find.
