I like the aussie in the front, with manual hubs. Aussie is less than 400 bucks from Indy4x, and fairly easy to install...if you are mechanically inclined. The ARB air locker is probably 3 times as much, if we can still get them for the 10 bolt front end. Plus install is no walk in the park.
Depends how much wheeling you are gonna do.
I just as soon disable TOD, since I have manual hubs on front, and in 4lo TOD does nothing as the power is even split 50/50 all the time.
