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)

(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)
