I'll chime in here as I've quoted the same actuators to Lippert.
These have a ball indent type clutch that starts to slip when overloaded. This is the loud clicking noise you hear at the end of travel. This clutch serves to protect the actuator gearbox from an over torque condition which would cause failure.
When you manually crank with a wrench, you bypass the gearbox.
Your slide is either a bit to difficult to move for some reason, or the clutch is not adjusted correctly. The former condition is the more likely.
I would see if there is a way to free up the slide somehow. Possibly silicone spray?
I did this with my underside floor mods (ref: slide underside wearing thread) and they move much more freely.
I hope this helps.
