Removal andInstallation (Cont'd)

• Install pipeconnector.
• Observe specified tightening torquewhentightening high-
pressure andlow-pressure pipeconnectors. Excessive
tightening willdamage threadsofconnector orO-ring.

Connector tighteningtorque:

Low-pressure side
27 -39 N'm (2.8-4.0 kg-m, 20-29 ft-Ib)
~ High-pressure side
15 -25 N'm (1.5-2.5 kg-m, 11-18 ft-Ib)

• The O-ring inlow-pressure pipeconnector islarger than
that inhigh-pressure connector.Takecaretoinstall the
proper O-ring.
• Initially, tightennutontie-rod outersocket andknuckle arm
to 29 to39 N'm (3to 4kg-m, 22to29 ft-Ib). Thentighten fur-
ther toalign nutgroove withfirstpinhole sothat cotter pin
can beinstalled.

CAUTION:
Tightening torquemustnotexceed 49N'm (5kg-m, 36ft-Ib).

• Before removing lowerjointfrom gear, setgear inneutral
(wheels instraight-ahead position).Afterremoving lower
joint, putmatching markonpinion shaftandpinion housing
to record neutral position.
• Toinstall, setleftand right dustboots toequal deflection.
Attach lowerjointbyaligning matching marksofpinion
shaft andpinion ~ousing.
• Tighten gearhousing mounting bracketboltsinthe order
shown.

Disassembly

1. Prior todisassembling, measurepinionrotating torque.
Record thepinion rotating torqueasareference.

• Before measuring, disconnectgearhousing tubeanddrain
fluid.
• Use softjaws when holding steering gearhousing. Handle
gear housing carefully, asitis made ofaluminum. Donot
grip cylinder inavise.

2. Remove piniongear.

Be careful nottodamage piniongearwhen removing pinion
seal ring.

3. Remove tie-rodoutersockets andboots.
4. Loosen tie-rodinnersocket byprying upstaked portion, and
remove socket.
5. Remove retainer.
6. Remove pinionassembly.
7. Use a2to 2.5 mm (0.079 to0.098 in)diameter drilltocom-
pletely remove stakedportion ofgear housing end.
8. Remove endcover assembly withasuitable tool.
9. Draw outrack assembly.
10. Remove rackseal ring.
• Using aheat gun,heat racksealtoapproximately 40°C
(104°F).
• Remove racksealring.

Be careful nottodamage rack.

11. Remove centerbushing andrack oilseal using tape
wrapped socketandextension bar.

Do not scratch innersurfaces ofpinion housing .
