I am new to the forums, great article on the vacuum hubs, very helpful. I do have a question though. I am trying to figure out how the vacuum system inherent in the KIA 4WD's work. Right from the switch in the cab, through to the hubs actually engaging. Does anyone have any idea of where to find a diagram etc? Canada Customs isn't agreeing with my contentions that the Vacuum Hub Locks, are part of a vacuum control assembly (that being the swtich, lines, seals, valves etc). Can anyone help with how the whole system works and the parts involved in the vacuum system?
