Steer Axle and Wheel
NOTE: Steer axles with tapered roller bearings shown.
(1) Do the steps that follow for steer wheel bearing adjustment. a. Tighten nut ① slowly to 135 N·m (100 lb·ft) while turning the wheel. b. Loosen nut ① completely.
Tighten it again to ....................... 50 ± 5 N·m
(37 ± 4 lb·Ift) c. Assemble lock washer ② and align the hole for assembling the bolt. If the holes does not match, turn nut ① about 1/32 turn clockwise. d. Apply loctite 242 on the threads of bolts ③ and tighten them at ................... 8 ± 3 N·m
(6 ± 2 lb·ft).
(2) Torque for bolt ④ that holds pin ....11±1 N·m
(100 ± 9 lb·ft)
(3) Loosen nuts
⑥
and
⑧
on both sides. Adjust bolts to get steering knuckle turning angle (A) of
78 to 80°.
See Steering Axle Stop Adjustment in Testing
And Adjusting section.
(4) Torque for bolts ⑨ that hold steer cylinder to axle beam…………300 ± 40 N·m (220 ± 30 lb·Ift)
1
9
(5) Torque for bolts ① that hold cover
………………………... 55 ± 6 N·m (40 ± 5 lb·ft)
(6) Add or remove shims ③ under cover until torque required to turn knuckle assembly is
……………………...4.5 to 6.8 N·m (40 to 60 lb·in)
