Old Old Old Dodge truck Mechanical question

You have to look at the whole system with a helper. Someone needs to sit in the truck and gently work the steering wheel back and forth while you look at everything. I dont remember what system that old of a truck uses but it could well be a solid beam axle. Look at each tie rod end for any movement. Look at any rubber bushings and spring mounts. Lift the front end off the ground and check for play. be careful when adjusting the gearbox as it can be worn and tightening the screw in the worn area results in to tight of a feel as the wheel is turned. There may be a combination of several loose areas. Rubber parts also deteriorate with time.
