Re: AWD to 2 wheel drive
You can't make an AWD vehicle into an effective 2wd unit. You'll need a part time transfer case that allows you to select rear wheel drive (2WD) only and then you can disconnect the front axle.
If this is to improve fuel economy, you're wasting your time. A part time system still turns both axles although only one is engaged. AWD is the better option to have as it's a set and forget system and you get full time traction from all wheels. AWD also has a center differential that allows tight turns on pavement and other hard surfaces without worry of binding the axles.
