ited service, it will affect original performance.
INSTALLATION
Reverse removal procedure for installation of steering gear box
noting the following points.

After confirming that front tire is in straight position, install steering
gear box to body temporarily. Next, with tie-rod end installed to
knuckle, set rack in position close to neutral. Then obtain the neu-
tral state by aligning match marks on pinion shaft and steering
gear case and insert steering lower joint into pinion shaft.
CAUTION:
Be sure to confirm that steering wheel and front tires
(wheels) are in straight position when inserting steering
lower joint into steering pinion shaft.

If a plug was put to disconnected pipe when removing steering
gear box, remove that plug before reconnecting pipe.

Use specified torque as given below.
Tightening Torque
