why with only 31's do you really need to be locked up solid all the way around? I'd say leave the front alone til you can save up for a locker, it seems too me like you think that having all 4 wheels pulling will make up for driver inexperience, just my .02. besides most people with 4wheeldrive vehicles think that they can go faster in the nasty stuff and they seem to forget they can't stop as quick as they can go.
