Hi you need to make the ball joint nut tight. Lift the truck up remove the cotter pin and get a bar in between the upper control arm and the frame and push the control arm down so that the ball joint goes into the taper farther it should hold the stud from turning. Better yet if you have a impack to tighten it up. Also never back the castle nut off to line up with the cotter pin hole tighten the nut so the next slot in the nut will line up with cotter pin hole. If you keep driving the truck with it looose you will screw up the taper and end up changing the spindle and maybe the ball joint. As for the truck pulling one thing at a time, get the ball joint tighten first.
