Purpose.

The purpose of this test is to determine the stick slip characteristics of passenger car and lightduty truck collapsible intermediate shafts (I-shafts) when subjected to axial displacement and constant torque. This procedure may be used for development or validation.

This test provides axial displacement in conjunction with a constant torque applied to the intermediate shaft. Results of the test will predict stick slip performance in a worst case scenario (large and or frequent stroking events between steering column and steering gear).

Applicability.

This procedure applies to body on frame and body frame integral vehicles.
