???\'s about a 90 3/4 ton 4x4 My brother just bought one and he asked for help changing carrier bearings in the rear. First off what rear is that? Im assuming (I havent seen it) its a 14sf because I know its not a ff. (He said it didnt have the bolt in axles) Also, are the gov-locs any good in the SF? Its a DD and he doesnt wheel it other than a little mud here and there and he doesnt want to buy a locker. Can the gov-loc be rebuilt? Thanks guys.
