Purpose. The purpose of this test procedure is to evaluate the pinion bearing used in a Rack and Pinion steering gear assembly.

Remarks. This test provides a constant axial and cyclical load to the pinion bearing for component level validation. The axial and radial loads are calculated based on driver input torques.
