Note: Nothing in this standard supercedes

precedence.
Purpose. The purpose of this test procedure is
to evaluate the pinion bearing used in a Rack and Pinion steering
gear assembly.
Applicability. This procedure is applicable to
all GM vehicles with Rack and Pinion steering gear pinion bearings
that resist both axial and radial loads.
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.
