10.2.4. Semi-axes



For an inhaling of a nut of a semi-axis the wrench with m regulated at least to 220 N the moment is required.


1. Unscrew a nut of fastening of a semi-axis by means of a dvenadtsatigranny face key of SW 30.


Thus, in order to avoid accident, the car should stand on wheels, transfer should be included, and the parking brake will tighten.

2. Designate paint the provision of wheels in relation to a nave. Thanks to it after removal it will be possible to return the balanced wheel into place. Release bolts of wheels when the car costs on the earth, then put it behind on supports and remove back wheels.
3. Unscrew a semi-axis (37) from a connecting flange (33). For this purpose unscrew bolts with an internal polyhedron (35) (SW 10 key, for example HAZET 2751 or 990 SLg 10) and remove them together with lock washers (34).


Watch the correct landing of a key in heads of bolts. It is desirable to clear previously internal polyhedrons in heads of bolts.

4. Put a garage jack under the suspension bracket lever, raise the lever that the semi-axis became approximately horizontally. Do not forget wooden laying between the lever and a jack.


When lifting watch to raising the car from supports.

5. Put forward a semi-axis, then reject obliquely down.


Watch that at removal of a semi-axis the shaft cover did not unscrew.

6. Take a semi-axis from a nave. If she sits strongly, use the ordinary suitable adaptation for its expression from a flange.
7. Get a semi-axis, check rubber cuffs and a cover on tightness and damages, if necessary repair.


1. Clear a surface between a flange and a semi-axis cover.
2. Insert a shaft into a nave.
3. Attach a shaft to a connecting flange.
4. Put new washers and new bolts with an internal polyhedron.

Previously slightly grease a carving and a surface of a prileganiye of bolts. Measure diameter of a carving as the inhaling moment depends on it.

5. Tighten bolts in diameter of 10 mm with the moment of 70 N of m in a crosswise order, and bolts in diameter of 12 mm with the moment of 100 N of m.
6. Lower and remove a garage jack.
7. Put back wheels so that the mark paint on a wheel and a nave coincided. Screw wheels. Lower the car and tighten bolts of wheels with the moment of 110 N of m.
8. Screw a new dvenadtsatigranny nut of fastening of a semi-axis in a nave and tighten with the moment of 220 N of m.

Previously slightly grease a carving and a prileganiye surface.

At this operation the car should stand on wheels. The nut is essentially replaced. At screwing up the parking brake should be tightened and transfer is included.

9. To Zachekanta a nut of fastening of a semi-axis on a fillet (shooter) for what hammer a nut fillet with a punch into a shaft cut.
