CAUTION: •
• The rotation ofthe spiral cable(SRS"Airbag" component
part) islimited.
If
the steering gearmust beremoved, set
the front wheels inthe straight-ahead direction.Donot
rotate thesteering columnwhilethesteering gearis
removed.
• Remove thesteering wheelbefore removing thesteering
lower jointtoavoid damaging theSRS spiral cable.
• Detach tie-rodoutersockets fromknuckle armswithTool.
• When disconnecting steeringshaftlower joint,follow the
procedure shownbelow.
1. Remove nutsforfitting thehole cover.
2. Disconnect thelower jointwhile shifting thehole cover.

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

proper O-ring.
• Initially, tightennutontie-rod outersocket andknuckle arm

ther toalign nutgroove withfirstpinhole sothat cotter pin
can beinstalled.
CAUTION:

• 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
