‘78 FJ40 with Spartan Locker. Is this Correct??? (1 Viewer)

I have had this Spartan locker in my ‘78 FJ40 for about 2K miles (including one wheeling trip). The truck has been bucking when idling through a parking lot. It felt like there was excessive lash’s honey were in the drivetrain. Pulled the rear diff cover and found this (see video).

There lash between the ring and pinion seems fine but the there seems to be quite a bit of rotation of the ring gear before the Spartan locker moves. Is this correct? Thx for any suggestions.
