(c) Using a brass bar and hammer, stake the claw washer.
NOTICE:
Avoid any impact on the steering rack.
(d) Employ the same manner described above to the other
side.
18. INSTALL RH AND LH RACK BOOTS, CLAMPS AND
CLIPS
(a) Ensure that the steering rack hole is not clogged with
grease.
HINT:
If the hole is clogged, the pressure inside the rack boot will
change after it is assembled and the steering wheel is turned.
(b) Install the rack boot, clip and a new clamp.
NOTICE:
Be careful not to damage or twist the rack boot.
(c) Using SST, tighten the clamp as shown in the illustration.
SST 09521-24010
(d) Employ the same manner described above to the other
side.
19. INSTALL RH AND LH TIE ROD ENDS AND LOCK NUTS
(a) Screw the lock nut and tie rod end onto the rack end until
the matchmarks are aligned.
(b) After adjusting toe-in, torque the lock nut (See page
SA-4).
Torque: 74 N´m (750 kgf´cm, 54 ft´lbf)
(c) Employ the same manner described above to the other
side.
