Fig. 9.17. 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.
The driving force of ball strut 8 (or housing 1 of the steering
knuckle, if the ball struts were not disconnected from the hous-
ing 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 clamp-
ing bush once again by turning the wrench by 10–20° and tighten
the nut 13 with the specied torque.
In case air gap persists following threaded bush tightening,
contact UAZ service to replace pins units liners.
