Figure 2 708 Power Steering Gear - Legend
STEERING GEAR ADJUSTMENTS
Important
•
Before any adjustments are made on the steering
gear, refer to “Steering, Suspension, Tires and
Wheels Diagnosis” (Section 3) for reviewing the
possible steering system problems. Any steering
gear adjustment is made only as a correction and not
as a periodic adjustment.
For proper adjustment, remove the steering gear from the
vehicle. Drain the power steering fluid from the gear. Mount
the gear in a vise and make the following adjustments.
The steering gear requires two adjustments:
•
The worm thrust bearing preload
•
The pitman shaft over-center preload
adjustment
The worm thrust bearing preload is controlled by the
amount of compression force exerted by the adjuster plug
on the conical worm bearing thrust races.
The pitman shaft over-center preload is controlled by the
pitman shaft adjuster screw, which determines the clearance
between the rack piston and the pitman shaft sector teeth.
|
9
| Important
Adjust the Worm thrust bearing preload first, then
adjust the pitman shaft over-center preload.
