JT,
I went through this excercise on two patrols (
mine and a friends).
I ended up changing to an ARB air locker and also changing the hubs to manual, the other one remained on the lockrite and is still doing it to this day, here is what happens.
On an open diff, when you reverse (in 2wd), the cam system unlocks the auto hubs sometimes one first the other one after (as they may be at different spots in the internal splines), you will hear a click on one side then a click on the other, once unlocked that is it...
When you have the lockrite (even if you were using it in manual locked position (by the way when changing from manual back to auto you don't disengage them, you then have to reverse for them to disengage)...
Back to the lockrite, which is always locked by default and unlocks when the cam system allows it to which is almost never as it was pointed out simply because the natural load between front and rear axles keep the load on...
When you reverse, the auto hubs work in the same way, as with an open diff however if they happen to be at different stages in the spline (that is one disengages earlier than the other) then the lockrite which is locked will drag it back to the locked position in reverse.
The only way to get both hubs successfully unlocked is by making sure both unlock at the same time while reversing (almost impossible).
The way I achieved it sometimes was reversing in a zig-zag until I decided to replace it for an ARB air locker, much better, later I also replaced the hubs for manual ones much better again....
