Throughout the life of your car, the steering column is quite often unintentionally abused. We try our best to keep good care of the column, as it is not a replaceable piece, and that often includes cleaning the threads when it comes to re-installing the steering wheel. Hiding underneath the steering wheel, the only thing that stands between you and the wheel flying off is the external lock washer & nut that secures the wheel to the column. Make sure your wheel can be firmly secured with clean threads and a new nut/washer!
