With an ARB (The only selectable locker I know for 7.5 ADD diffs) It would function as open diff (no driveshaft spin) until you locked it, then the driveshaft spins with or without engaging the ADD unit. Again, ADD only lets you pick 3 or 4 wheel drive. Might as well ditch the complexity and switch to manual hubs and remove the ADD.


ADD stands for Automatic Differential Disconnect.[/QUOTE]

to completely remove the add in a 2.4 lte 5 speed manual do you need to swap the tcase , at the moment we press the button on the gear stick and you hear it click on the tcase but doesnt engage and the front drive shaft , any help or ideas will be great
