I rebuilt the saginaw on my brothers truck its a 1971 gmc 4x4 longbed,the steering box is off a 1979 2wd chevy 1/2 ton pickup and it has a dana 60 kingpin with offroad design high steer ,and a 1998 vortec big block 454 with stock steering pump and hydroboost,38inch swampers and 8 inch lift ,i used a west texas offroad rebuilt kit so i rebuilt the box and was wondering about the putting the balls in the power piston , i know that the input assembly flat spot should be parrellel with top of box , but when installing ball bearings i rotated the power piston 45 degrees in the housings and put all the bearings and crossover tube in and reassembled , but the the box would not steer all the way in both directions, so i took it apart again and rotated the power pistions to 45 degrees and did the same to the input assembly and reinstalled the ball bearings and crossover tube and rotate both input assembly back up and installed sector shaft and put back in truck bled it and i seems a little tight when turning and gets hard when turning left at end of stroke . so my questions are if the box is just tight from all the new seals , and what about my aligment of the input and power piston any info would be great,
