I would have to see some estimates as to how many miles per gallon it would save me. Still, my gut tells me that I would not be able to justify the expense of a hub change. There's nothing in the owner's manual about reversing to disengage the hubs, so they are either permanently fixed or they just automatically disengage when 2wd is selected. I may still jack up the front end to figure that one out for curiosity's sake.
