Hey guys i'm doing some mods to a 93 runner, it has the orig automatic hubs on it and i want to try to get some better gas mileage. If i swap them over to a pair of Warn manual locks will this help me any??? Thanks for the help. I am trying to drive the truck to work and with gas prices going all over the place i need a cheaper route, any other gas saving ideas, also please advise. Much appreciated.
