STEERING
DESCRIPTION
The power steering system consist of a steering col-
umn, steering gear and hydraulic pump. The gear is
mounted to the frame rail and attaches to the steer-
ing linkage. The pump is a constant flow rate and
displacement vane-type pump. The pump supplies
hydraulic fluid pressure to the power steering gear
(Fig. 1).
Vehicles equipped with trailer tow option have a
power steering pump oil cooler.
OPERATION
The gear acts as a rolling thread between the
worm shaft and rack piston. The worm shaft is sup-
ported by a thrust bearing at the lower end and a
bearing assembly at the upper end. When the worm
shaft is turned from input from the steering column
the rack piston moves. The rack piston teeth mesh
with the pitman shaft. Turning the worm shaft, turns
the pitman shaft, which turns the steering linkage.

LINKAGE - 4WD
DESCRIPTION
The steering linkage is comprised of a tie rod end,
tie rod, drag link, steering damper and pitman arm
(Fig. 1).
CAUTION: If any steering components are replaced
or serviced an alignment must be performed.
NOTE: To avoid damaging ball stud seals, use
Puller C-3894±A or an appropriate puller to remove
tie rod ends (Fig. 2).
STANDARD PROCEDURE - LUBRICATION
Periodic lubrication of the steering system compo-
nents is required. Refer to Lubrication And Mainte-
nance for the recommended maintenance schedule.
The following components must be lubricated:
²Tie rod
²Tie rod end
²Drag link
REMOVAL
(1) Remove steering damper mounting nuts and
bolts and remove damper.
(2) Remove tie rod nuts.
(3) Remove tie rod from drag link and left knuckle
with Puller C-4150A.
(4) Remove drag and nuts.
(5) Remove drag link from right knuckle and pit-
man arm with Puller C-4150A.
(6) Mark the pitman arm and shaft positions for
installation reference. Remove the nut and washer
from the pitman arm. Remove the pitman arm with
Puller C-4150A.
