No, the axle is just one component of the full time system. The other major part of the system is your transfer case. You need to convert it to PT or swap t-cases to one that is PT.Floyd said:I have a '78 RC FT 4wd 4sp. the question is if I install locking hubs on the front will that alone convert it to PT?
Your transfer case is designed to turn both front and rear at all times. Your t-case is equipped with a differential which only works in a non-lock position. If you try to drive the truck with the front axle disengaged and the t-case is shifted in a non-lock position, the differential will send all engine power to the side with least resistance and you go no where. You'll have to drive the truck with the t-case always in a locked position. However there is a PT conversion kit available for your t-case. The unit is made by Mile Marker and it's not too hard to install.Correct me if I'm wrong, but it seems to that would be enogh. OR do I have to shift to LOC with front hubs unlocked to drive 2wd
