Now that does bring up an interesting point. Outer column is grounded by a ground wire to the frame. The inner shaft relies on the steering gear to ground. My upper bearing is insulated wit a rubber sheath around it. However my original upper bearing sheath had a staple stuck through it ( think desk/ paper staple) that would technically ground/ connect the inner shaft with the outer housing. Was that staple there for a purpose? Or it had a tag on it once and they left the staple in?
