Through an arch of a wheel unscrew pressure head and returnable hoses of hydraulic system of the amplifier of steering (fig. 14-16) from the steering mechanism.
In the presence disconnect the electric socket from Servotronic valves.

Fig. 14-17. Arrangement of bolts of fastening of the steering mechanism



Through an arch of a wheel unscrew two bolts of fastening of the left side of the steering mechanism (fig. 14-17).
Disconnect the steering mechanism from the lock mechanism from a reverse side of the accumulative camera.
Remove the steering mechanism from the car through a wheel arch.

Installation
At installation it is necessary to use new nuts, sealing rings and collars.

Fig. 14-18. An arrangement and freedom of movement of hydraulic hoses of the steering mechanism before its installation on the car



Check freedom of movement and the provision of hoses of the steering mechanism (fig. 14-18).
Install the steering mechanism and fix it the lock mechanism from a reverse side of the accumulative camera.
Fix the steering mechanism by bolts, having tightened them in the sequence And, In and With the moment of 70 N · m (see fig. 14-17).
Release the mechanism of adjustment of a steering column and establish it in the situation close to horizontal.
