Removal

PERFORMANCE ORDER
1. Lift the car and remove a forward wheel.
2. Turn out a nut of fastening of a power shaft.
3. Remove a support and fix by a soft wire it on a forward rack.
4. Remove the rotation frequency sensor from a rotary fist.
5. Take the forelock and turn off a nut of fastening of a pin of the spherical hinge of a tip of steering thirst for a rotary fist. A stripper 09568–34000 squeeze out a pin of the spherical hinge from a rotary fist.
6. Note situation and turn out bolts of fastening of the lower part of a rack of a forward suspension bracket to a rotary fist.
7. The kapron hammer beat out a power shaft from a nave of a forward wheel. If the power shaft densely sits in a nave of a forward wheel, spray impregnating aerosol solvent on area of shlits and then repeatedly screw a nut with a fillet so that it settled down flush with a shaft end face. Striking a nut with the brass hammer, beat out a power shaft from a nave.
8. A stripper 09568–34000 disconnect the spherical hinge of the lower lever from a rotary fist.
9. Remove a rotary fist together with a nave of a forward wheel.
10. Installation is carried out to the sequences, the return to removal.

Dismantling

PERFORMANCE ORDER
1. Remove a brake disk from a nave of a forward wheel.
2. Remove a lock spring ring.
3. Install special tools, as shown in the drawing.
4. Turning the special tool, remove a nave of a forward wheel from a rotary fist.
5. Remove the special tool and a dustproof ring.
6. The special tool remove an internal ring of the bearing from a nave.
7. The special tool remove an external ring of the bearing from a rotary fist.

Check

PERFORMANCE ORDER
1. Check a nave for lack of cracks and wear.
2. Check a brake disk for lack of development and damages.
3. Check the hinge for lack of cracks.
4. Check a spring ring for lack of cracks or damages.

Assembly

PERFORMANCE ORDER
1. Apply a thin film of jellied lubricant in an opening of a rotary fist and on an external ring of the bearing.
2. A press with a mandrel of the corresponding diameter press the new bearing of a wheel.

Prevention

Do not make effort of a press for an internal ring of the bearing.


3. Establish a dustproof ring.
4. A press with a mandrel of the corresponding diameter press a nave in the wheel bearing.

Prevention

Do not make effort of a press for an external ring of the bearing.


5. Establish a brake disk.
6. The special tool tighten a nave to a rotary fist, having tightened adaptation bolt the moment of 240 N • m.
7. Several times turn a nave that elements of the bearing were established on the places.
8. Measure torque which needs to be put for a bearing provorachivaniye.

Torque: 1,3 N • m

9. If torque of 0 N • m, measure an axial side play of the hug bearing.
10. If the torque exceeds the required value, so the bearing is incorrectly installed in a rotary fist and on a nave. Sort a rotary fist and repeatedly collect it.

Axial side play of the bearing: 0,08 mm

11. Remove the special tool.
