I removed the left side steering linkage (drag linkage) as part of the front axle case oil seal replacement. The split pin and castellated nut was removed from the drag linkage easily. However, during installation of the castellated nut the drag linkage threaded stud spins in place and the nut cannot be tightened appropriately. Not sure why, because the threaded stud didn’t spin during removal. At this point, the nut is only a couple thread revolutions in, can’t be removed and can’t be tightened. Advice?? TIA. ~Brian
