I have a 47 3600 with a 1/2 ton straight axle. I went with a Saginaw power steering conversion kit from CPP and am just now starting to do test drives on the truck. I have bad bump steer and it wanders on the road. It seems to be working fine, I just need to iron out some bugs. I guess it's fine tuning? I'm going to try leveling the drag link to parallel with the ground? Overall so far this kit has been underwhelming. There's gotta be something better. I was trying to save money but I'm not happy with the results to this point.
