Nissan Titan Rear Differential Failure
The diff lock solenoid sits on top of (actually just beside) this plate.

The plate is tabbed into the lock ring, and the lock ring is tab locked in the
diff carrier.

The lock ring is being held up here by a spring between it and the locker end
side
gear. Pushing on these tabs will move the lock ring into the locker end
side gear.
This is what occurs when power is applied to the diff lock solenoid - the plate
is pushed away from the diff lock solenoid, which pushes the lock
ring (against spring pressure) into the locker end side gear. Because the
lock ring can not rotate within the carrier, the locker end side gear is locked
to the carrier when mated with the lock ring. The spider shaft is integral
with the carrier, so the non-locker end side gear is also locked.

This is the lock ring - upside down from its position in the pic above.
Notice the perfect teeth on both the lock ring and the locker end side gear.
That indicates adequate spring pressure - the locker never "accidentally" tried
to lock.
Proof that neither the locker nor components specific to the e-locker are to
blame for the diff failure.
