The intermediate steering shaft doubles as the key component, comprising the Energy Absorbing Steering Column. A two-piece design, one shaft slides into the other during impact, and is intended to prevent the steering column from further injuring the driver. It also absorbs the force should the driver contact the column during the crash. The column design varies with model year and application. The unit on our ’72 T/A was filled with molten plastic during assembly, and the plastic breaks away upon impact, allowing the column to collapse. This type was not intended to be serviceable, and that makes replacing the rubber boot a bit challenging.
