My steering wheel is broken.
The issues you describe is a common fault with older ford trucks. It is most commonly caused by faulty bearings inside of the steering wheel column. To inspect the bearings, a technician will need to remove the steering wheel. I recommend checking other steering components such as the drag link and the steering dampener while diagnosing this issue because other steering parts are likely faulty in a truck of this age. A certified mechanic will be able to check out your vehicle and determine what is wrong with your steering wheel.
