Collapse Measurement

A vehicle involved in an accident resulting in sheet metal damage or drivers-side air bag deployment will require an inspection for steering column collapse. If the steering column collapse measurement is greater than 3 mm than the steering column assembly must be replaced.

For steering column collapse measurement, use the following procedure:

1. Remove the steering column trim covers. Refer to Steering Column Trim Cover Replacement .
