Figure 6.10. Removing the windshield pillar trim: 1 - lining; 2 - overlay
- remove the upper part of the instrument panel, for which pull the lining of the pillars of the windshield opening. To do this, it is enough to detach the lining so that you can press the upper latch, then move the lining 1 (Figure 6.10) and disconnect it from the lining 2;
Figure 6.11. Side screw of fastening of the panel of devices (left side of the panel)
- unscrew the two side screws securing the instrument panel (Figure 6.11);
Figure 6.12. Four screws securing the instrument panel
- remove the three screws from the top (near the windshield) (Figure 6.12) and completely remove the upper part of the instrument panel;
Figure 6.13. Four screws securing the instrument cluster
- remove the six screws securing the instrument cluster (Figure 6.13 and 6.14), disconnect four contact sockets and remove a combination of devices;
Figure 6.14. Two screws securing the instrument cluster
- release the latch and disconnect the switch wiring connector (castle) ignition;
- in the engine compartment, remove the air pipe, unscrew the nuts securing the expansion tank and remove the tank to gain access to the steering shaft universal joint yoke;
- unscrew the bolt of the steering shaft universal joint yoke connection, before disconnecting the shaft, mark the relative position of the splined parts;
Figure 6.15. Six steering column bolts (arrows) and protective case (1) motor shield
- remove the six steering column mounting bolts (Figure 6.15) and pull the protective cover of the motor shield;
- remove the steering column;
Figure 6.16. The control size of the intermediate shaft of the steering column: L= (416,6±1,5) mm
- inspect the removed steering column. The intermediate shaft of the column is equipped with a telescopic safety element, which, in the event of a car impact, is compressed, preventing injury to the driver's chest. The length of the telescopic part of the shaft must be (416,6±1,5) mm (Figure 6.16). If the shaft length differs from the specified, the steering column assembly is replaced. Check the play in the universal joints of the steering column, the turns of the universal joint forks should be easy, without jamming. In case of damage, completely replace the steering column.
Assembly
- install the steering column from the passenger compartment, aligning the spline connection of the shaft and the steering mechanism according to the previously made marks;
Figure 6.17. Pass the string through the holes in the protective cover to install the cover on the motor shield
- tie twine around the steering column protector and universal joint yoke (Figure 6.17) and pull it from under the car into the hole in the engine shield. After installing the cover, cut the twine;
- install the eccentric bolt with nut, tighten the connection to the prescribed torque. Reinstall the protective cover of the connection.
Carry out the remaining operations in the reverse order of removal, paying attention to the following:
- make sure that the front wheels are in the straight ahead position of the vehicle;
- set the stalk correctly, positioning the fixed mark against the movable (see Figure 6.7);
- connect all the connectors according to the previously made marks;
- complete the installation and finally tighten the screw of the stalk fastening clamp only after both halves of the stalk cover are installed, while the stalk levers must be installed without distortion relative to the instrument cluster. This operation is facilitated by a cutout in the lower casing of the steering column switches, providing access to said screw;
- after each removal, replace the steering wheel bolt with a new one (it is supplied with a microcapsule with glue).
