2. Remove the steering wheel.
3. Loosen the bolts and remove the lower steering column cover (figure 9.1).

4. Unscrew the three bolts and remove the combination switch. Disconnect the electrical wires.
5. Loosen the bolts and remove the lower casing of the indicator set on the distribution board.
6. Loosen and remove the column mounting bolts. Where bolts with a shear head are installed, it will be necessary to drill through the heads and unscrew the threaded parts or use a punch to remove them. In some car models, one of the mounting bolts may have a faceted head.
7. Loosen and remove the clamp bolt securing the cross joint to the column (photo 9.6). Loosen the cross bolt of the lower mount to the column, then remove the column from the cross joint and remove the bolt spring.
8. Models before July 1984 had a two-piece column. With this type of column, you push the two parts together to separate the kingpins, which are connected in a rectangular parallelepiped shape inside the housing, remove the separating rubber boots, and pull the lower part up through the housing tube
9. Check the components for wear. If the steering column has been damaged, it must be replaced as a set. In case of replacing an older type of column, a new telescopic column unit can be fitted as a set, but then a new type of lower bracket must also be installed. because the old one will not fit.
10. To disassemble the upper case (for two types of columns), it is necessary to lift and remove the safety washer from the inner column, remove the spring and contact ring. Replace the washer with a new one
11. Check the condition of the cuff bushings and replace them if necessary. Remove the old bushings by lifting them with a screwdriver, and immerse the new ones in a soap solution and press them into place of the old ones.
12. Using a hex key, loosen the clamp bolt securing the steering wheel lock and remove the lock. Remember that the ignition key must be inserted and the lock released.
13. Remove the column axle and remove the support ring (figure 9.2)

14. Clean the components and check them for wear. Replace them with new ones if necessary.
15. Assembly is performed in the reverse order of disassembly. It is necessary to pre-lubricate the bearing surfaces with universal grease.
16. In newer models of cars equipped with a one-piece telescopic column, installation is different.
Secure the lower end of the steering column axle in a vice with soft jaws so that the upper section is in the jaws and the two parts of the steering column cannot move together. Small protrusion at the bottom of the steering shaft (indicated by the arrow in Fig. 9.2) should be visible through the hole in the steering shaft housing. Install the support ring with the column switch and the lock housing, the contact ring, the spring and the safety washer together (figure 9.3).

17. In both types of columns, the safety washer is installed by hammering it onto the steering shaft until it is fully pressed in. In the older two-piece type, press the two elements of the column together with suitable pliers until the washer is in place.
18. When connecting a column with a cross joint, check whether the column axis is installed correctly. Tighten the fastening bolts and nuts with a torque of a certain value. Tighten the bolts with a sheared head until their heads come off.
19. Finally, it is necessary to check the operation of the steering wheel, all switches on the column and the sound signal.
