well, I ve driven a hundred miles an the pinion berring went south . i just love it . mo money.So i have to get a new one and the old one did not have posi ,so do i get one with posi- trac loc or torque lock ? I heard they make a banging noise when you turn? Ill change the rear end ratio to 3.50 at the same time. Does everybody have posi ?Does it change the handling? Any info would be nice.
