DESCRIPTION AND OPERATION
STEERING SYSTEM
DESCRIPTION
The power steering system has a hydraulic pump.
The pump is a constant flow rate and displacement,
vane-type pump. The pump on the 4.0L engine has a
reservoir mounted to it (Fig. 1). The 2.5L engine has
a remote mounted reservoir.
The steering gear (Fig. 1) used is a recirculating
ball type gear with 14:1 gear ratio. A tilt and non-tilt
column provide steering input.
NOTE: Right hand drive (RHD) and left hand drive
(LHD) service procedures and torque specifications
for steering linkage, gear and column are the same.
The power steering pump procedures are different.
Refer to appropriate service procedures regarding
each component in the system.
OPERATION
The steering gear acts as a rolling thread between
the worm shaft and the rack piston. Power assist is
provided by the hydraulic pump. When the steering
wheel is turned the worm shaft turns which moves
the rack piston. The rack piston movement turns the
pitman shaft which is connected to the steering link-
age by the pitman arm.
