NOTE: Do not install the wormshaft or pitman
shaft seals (22-23) at this time.
Mount the gear housing in a vise. Clamp the vise
jaws on the housing mounting bosses only.
Install the assembled worm bearing adjuster
(19) in the housing. Tighten the adjuster only
enough to remove wormshaft end play.
Install the locknut (20) on the worm bearing
adjuster but do not tighten the locknut at this
time.
Pack the steering gear housing with as much
chassis grease as possible.
NOTE: To pack the maximum amount of grease
in the housing, move the ball nut back and forth
for better access to the housing interior. Rotate
the wormshaft in one direction until ball nut
travel ceases. Pack the unobstructed housing
end full of grease. Then rotate the shaft in the
opposite direction and repeat the packing
procedure.
Place the ball nut in a centered position. Rotate
the wormshaft from stop-to-stop and count the
total number of turns. Turn the wormshaft back
1/2 of the number of turns to center the bail nut.
Measure adjuster screw end play with a feeler
gauge (D) inserted between the screw head and
the T-slot surface in the pitman shaft (7). End
play must not exceed 0.05 mm (0.002 inch).
Assemble a shim pack that will provide the
required end play.

Lubricate the pitman shaft (7) with chassis
grease and install it in the housing. Engage the
center tooth of the shaft in the center groove of
the ball nut (12).
