REMOVAL
(1) Unseat and remove retaining ring from groove
with a punch through the hole in the end of the
housing (Fig. 32).
(2) Slowly rotate stub shaft with 12 point socket
COUNTER-CLOCKWISE to force the end plug out
from housing.
CAUTION: Do not turn stub shaft any further than
necessary. The rack piston balls will drop out of the
rack piston circuit if the stub shaft is turned too far.
(3) Remove O-ring from the housing (Fig. 33).

CAUTION: The rack piston balls must be installed
alternately into the rack piston and ball guide. This
maintains worm shaft preload. There are 12 black
balls and 12 silver (Chrome) balls. The black balls
are smaller than the silver balls.
(4) Lubricate and install rack piston balls through
return guide hole while turning worm shaft COUN-
TERCLOCKWISE (Fig. 40).
(5) Install remaining balls in guide using grease to
hold the balls in place (Fig. 41).
(6) Install the guide onto rack piston and install
clamp and clamp bolts. Tighten bolts to 4.8 N´m (43
in. lbs.).
(7) Insert Arbor C-4175 into bore of rack piston
and hold tool tightly against worm shaft.
(8) Turn the worm shaft COUNTERCLOCKWISE
while pushing on the arbor. This will force the rack
piston onto the arbor and hold the rack piston balls
in place.
(9) Install the races and thrust bearing on the
worm shaft and install shaft in the housing (Fig. 39).
(10) Install the stub shaft with spool valve, thrust
support assembly and adjuster nut in the housing.
(11) Install the rack piston and arbor tool into the
housing.
(12) Hold arbor tightly against worm shaft and
turn stub shaft CLOCKWISE until rack piston is
seated on worm shaft.
(13) Install pitman shaft and side cover in the
housing.
(14) Install rack piston plug and tighten to 150
N´m (111 ft. lbs.).
(15) Install housing end plug, (Refer to 19 -
STEERING/GEAR/STEERING GEAR HOUSING
PLUG - INSTALLATION).(16) Adjust worm shaft thrust bearing preload and
over-center rotating torque, (Refer to 19 - STEER-
ING/GEAR - ADJUSTMENTS).
