The steering gear assembly with steering rods is attached in the engine compartment to the front body shield on two brackets using clamps 2 (figure 7.1). The mechanism is secured with nuts on welded bolts through rubber supports 6.
In the crankcase 26 (figure 7.2) the steering gear has a drive pinion 8 mounted on ball and roller bearings, which is engaged with rack 9. The pinion ball bearing and separator 7 are pressed by cover 5 assembled with seal 4 and are covered by boot 1. Marks for correct assembly of the steering gear are made on the steering gear housing and boot.
The steering rack 9 is pressed against the teeth of the drive gear by a spring 15 through a metal-ceramic stop 18, sealed in the crankcase by a rubber ring 17. The spring is pressed by a nut 14 with a locking ring 16, which creates resistance to unscrewing the nut.
A protective cap is placed on the left side of the steering gear housing, and a pipe with a longitudinal groove is pressed on the right side. The pipe on the right side also has a protective cap. The spacer bushings of the rubber-metal hinges of the inner ends of the steering rods pass through the groove of the pipe and the holes in the protective cover 1 (see figure 7.1). The steering rods are attached to the rack with 20 bolts (see figure 7.2), which pass through the connecting plates 22 and the spacer bushings of the rubber-metal hinges. The bolts are secured with a locking plate 21.
The steering drive consists of two composite steering rods and pivot arms of the telescopic struts of the front suspension. The length of each steering rod is adjusted by rod 5 (see figure 7.1), which is screwed onto the internal tips 1 and onto which, in turn, the external tips 4 are screwed.
Information about malfunctions in the operation of the electric power steering is provided by its electronic control unit when the ignition is turned on - the indicator in the instrument cluster flashes (light fault code) (see Electrical Equipment section "Electric Power Steering Control Unit").
