Steering Columns - CHRYSLER Corp.: Description
Chrysler steering columns are designed with impact-absorbing features to protect the driver in the event of a head-on collision. The column housing is made of slotted steel mesh and will deform upon impact. The steering shaft and shift shaft (column shift vehicles) are each made of telescoping 2-piece shafts, interconnected by plastic inserts. These shafts will collapse on impact. The steering column-to-instrument panel mounting bracket is designed to let the column compress or collapse away from the driver, but prevents rearward movement toward the driver.
NOTE:
When working on a collapsible steering column, do not hammer on or bump column components. With column removed from mounts, it is extremely susceptible to impact damage. A slight impact on column end may collapse steering shaft or loosen plastic injections that maintain column rigidity. When removing steering wheel, use a puller, but do not hammer or pound on any components to aid in removal.
