5) Apply grease to sliding surface of sleeve and
spring seat, then insert sleeve into pinion housing.
Fit spring into sleeve screw, pack grease inside of
screw, then install the screw.

6) Fit new lock washer on screwed portion of rack
end. Aligning cut portion of rack and nail of washer,
screw in and tighten ball joint by using ST and
spanner.
ST 925700000 WRENCH
Tightening torque (Ball joint):
78
±10 N´m (8.0±1.0 kg-m, 58±7 ft-lb)
CAUTION:
Pay attention to prevent rack surface on the
right side from being damaged by a tool or the
like, otherwise oil leakage might be caused.
G4M0107
NOTE:
While tightening ball joint, hold rack with ST to
prevent it from revolving.7) Bend lock washer using a chisel.
CAUTION:
Be careful not to scratch rack when bending
lock washer.

8) Rack and pinion backlash adjustment
(1) Loosen adjusting screw.
(2) Rotate input shaft so that rack is in the
straight ahead direction.
(3) Apply grease to sleeve.

(5) Apply liquid packing to at least 1/3 of entire
perimeter of adjusting screw thread.
Liquid packing:

(6) Tighten adjusting screw to 15 N´m (1.5
kg-m, 11 ft-lb) and back off 26É.
(7) Install lock nut. While holding adjusting
screw with a wrench, tighten lock nut using ST.
ST 926230000 SPANNER
Tightening torque (Lock nut):
39
±10 N´m (4.0±1.0 kg-m, 29±7 ft-lb)
NOTE:
IHold adjusting screw with a wrench to prevent it
from turning while tightening lock nut.
IMake adjustment so that steering wheel can be
rotated fully from lock to lock without binding.
9) Check for service limit as per article of ªService
limitº.
Make replacement and
adjustment if necessary.
10) Install boot and mounting rubber to housing.
NOTE:
Apply grease through small hole in boot.11) Fit clip (large) to boot, and then install boot to
gearbox while holding boot flange.
After installing boot, fold back boot flange to the
extent that large clip can not be seen.
G4M0123
NOTE:
IBefore installing boot, be sure to apply grease to
the groove of tie-rod.
IInstall fitting portions of boots to the following
portions in both sides of assembled steering gear-
box.
(1) The groove on gearbox
(2) The groove on the rod
IMake sure that boot is installed without unusual
inflation or deflation.
12) Turn boot until it seats well on gearbox and
rubber mounting, then bend boot flange back.
