I’m having the hardest time finding a non ADD tube/ axle assembly for my 95. Does anybody know of a website or something I could find one one that maybe I haven’t looked? Or also was seeing maybe if an ADD tube assembly would work being that my tires wouldn’t lock in until I turned the hubs into lock. Just didn’t know if the vacuum on it was to lock in the 4x4 or when the vacuum was off is when it locked in
