Fig. 9.26. Steering knuckle and wheel hub:
1 — steering knuckle housing; 2 — pin; 3 — pin liner; 4 — spring; 5 — outer
O-ring; 6 — inner O-ring; 7 — joint; 8 — ball strut; 9 — outer oil seal housing;
10 — clamping bush; 11 — spacer; 12 — plate; 13 — nut
WARNING! Tightening torque excess will cause lower pre-load
and pin unit failure.
The driving force of ball strut 8 (or housing 1 of the steering
knuckle, if the ball struts were not disconnected from the housing of
the axle shaft) in any direction relative to the common axle shaft of
the pins should be within the limits of 10-25 N•m (1.0-2.5 kgs•m)
considering the removed O-rings 5, 6 and joint 7 of the steering
knuckle.
In case the control parameter is not reached, tighten the
clamping bush once again by turning the wrench by 10-20° and
tighten the nut 13 with the specified torque.
In case air gap persists following threaded bush tightening,
contact UAZ service to replace pins units liners.
