The oil supply to the steering mechanism is provided by a pump continuously. Under normal conditions, very little pressure is required to maintain oil flow, which guarantees minimal engine power take-off. When the vehicle is parked or turned around, a rotary valve integrated in the worm shaft closes off the free flow of oil, providing an almost instantaneous increase in pressure.
The design of the steering drive is quite simple. It consists of a tie rod, tie rod and steering damper. It is possible to lubricate the ball joints - just unscrew the plugs and install special fittings for connecting a grease gun instead of them.
The worm shaft of the steering mechanism is connected to the steering column shaft by means of a flexible coupling (the placement of the steering gear on the car is shown in the accompanying illustration).
The steering gear and steering pump components do not need to be lubricated. In the event of a failure of the hydraulic booster system, the steering continues to function normally, however, the effort required to turn the steering wheel increases. Since the internal components of the steering gear and pump are lubricated by hydraulic fluid, in the event of a loss of hydraulic power, the source of fluid leakage should be identified and eliminated without delay to avoid wear and failure of mechanical components.
Models of later years of release (since 1992) with utility bodies (Van) (Utility) and mini truck (Cab-Chassis) can be equipped with coil spring suspension as an option. This uses a steering gear of the same design as on models with hardtop bodies (Hardtop) and Universal (Station Wagon). All procedures are performed in the same way as described in the text of the relevant Sections below.
The steering mechanism on models of later years of production was modified. The procedure for performing all procedures remains the same as described in the relevant Section of this Part of the Chapter Front and rear axles, running gear and steering, taking into account the points specified in the text of the Section.
