How can an upward pull on a steering column be achieved while using a come-along?

Using a large piece of cribbing between the top of the dashboard and the pulling chain effectively creates the necessary leverage to achieve an upward pull on the steering column. Cribbing is designed to provide stability and support when applying force, allowing for a more controlled and effective pull. In this context, placing the cribbing between the dashboard and the chain helps to distribute the force and minimizes the risk of damage to the vehicle's interior components.

This method allows for the vertical movement of the steering column, necessary during a vehicle rescue operation, especially when the vehicle has occupants trapped inside. The cribbing acts as a wedge, giving the operator the ability to exert a significant upward force that can free the steering column from its compromised position.

The other options do not provide the same level of effectiveness or leverage for achieving the desired upward motion on the steering column.
