IF the switch is in L2 and the vehicle is under load , say the boat ramp scenario, rear wheel starts spinning and driver hits the switch with the driveline at speed and under load, would the ADD try to engage and damage the spline?
Or does the ADD ecu already have a speed sensor forcing you to bring the driveline to a rest before it engages.

Martyn I am not being critical of your question, or you for asking it, so please take my answer with a grain of salt...
I would imagine anyone with a basic rudimentary mechanical understanding wouldn't attempt to engage the ADD whilst moving and with 4WD engaged. No matter how cleverly you engineer something there is always someone stupid enough to stuff it up.
Maybe we should ask anyone who has installed the switch if they have damaged their vehicle trying to do this, or if in fact they would be dumb enough to engage the ADD in that way...

There is no need to engage in 2WD,as you can see one axle is attached to the diff centre at all times, even in an open diff this connection will be enough to rotate the diff centre and lubricate everything.

If the lubrication is plentiful why does the manual require monthly 4x4 driving in order to lube stuff?
