Remove prop shaft, lock centre diff. Not sure why you would want to.

 

Centre lock happens after low range is engaged.

 

You would probably wreck the clutch discs as the front isn’t meant to handle 100% of the power all the time. Why would you want it to be front wheel drive?

 

Agreed.

 

I drove mine home after a cv joint failed, 3 hour trip turned into 6 hours driving 60kmh all the way with centre diff locked, kept eye on all temps all times she ran pretty sweet
