UAZ Pickup and UAZ Cargo spare wheel are placed at the
rear underbody part and should be securely xed to the hold by
a sector.
Move the wheel away from exhaust manifold to a 40 mm air
gap prior to wheel adjustment to avoid a tyre burnout from exhaust
manifold when using exhaust system with rear wheels exhaust pipe.
Wheel hubs
The presence of a gap in the bearings being checked by rocking
the wheel in the vertical plane.
To change grease, remove the hub from the stub axle, remove
old grease, thoroughly wash the bearings and the cuff. Grease the
bearings and the working edge of the cuff. Fill the space between
the bearings rollers with the grease. Apply 10–15 mm of grease
between the bearings. Do not apply too much grease into the hub
to avoid its contact with break mechanisms.
Thoroughly adjust the bearings. If their tightening is loose,
the vehicle movement provokes shocks in them, and, as a result,
damages the bearings. If the tightening is too tough, the bearings
overheat, the grease leaks and the bearings break down. Moreover,
big air gaps in the front wheel hubs increase brake pedal travel.
Adjust the wheel hub bearings in the following sequence:
1. Hang the motor vehicle or lift the jack from the side of the
wheel whose bearings are to be adjusted.
2. Remove the wheel coverage. Take out axle shaft 9 (Fig. 9.19)
of the rear axle or remove the driving ange of the front axle.
3. Unbend the tab of locking washer 6, loosen lock-nut 7 and
remove the locking washer.
4. Loosen the bearings adjustment nut 4 1/6–1/3 of a turn
(1–2 sides).
5. Rotate the wheel by hand to check it for easy turning (the
wheel should rotate freely without the brake shoes rubbing against
the brake plate or the drum).
