POWER STEERING GEAR SERVICE

The Saginaw recirculating ball, power steering gear
(Figure 8-29), is a fully serviceable component. The gear can
be adjusted, or overhauled as needed. Overhaul requires that
the gear be removed from the vehicle as repair can only be per-
formed on the bench.
The steering gear adjustments described in the overhaul section
can be performed on the bench or in the vehicle. Refer to the
adjustment section for details.
