remove the toothed washers located between the steering gear and the sub-engine frame;
remove the steering gear through the wheel arch on the driver's side.

To install the steering gear:

when installing, it is necessary to use new studs 2, self-locking nuts and rubber sealing rings for the high and low pressure pipes;

Figure 7.14. When installing the seal, it is necessary to align the mark on the seal (1) with the boss (A): DD - mark for vehicles with right-hand drive; DG - mark for left-hand drive vehicles

check the correct position of the seal 1 (figure 7.14) on the boss A in relation to the side of the steering wheel in the car. For right-hand traffic, it is necessary to align the DG mark with the A boss;

Figure 7.15. Steering mechanism: 1 - protective case; 2 - ventilation tube; B - supporting surface of the seal

apply a thin layer of LUBRICOMET SP70 grease to the bearing surface B (figure 7.15) sealant;
check the reliability of the fastening of the ventilation tube 1 with brackets and its connection with the corrugated protective covers 2.

Installation is carried out in the reverse order of removal, taking into account the following:

fill the power steering hydraulic system with working fluid;

Attention! Tighten studs 2 (see Figure 7.13) torque of 7.5 Nm. Tightening torque greater than 7.5 Nm will result in destruction of the steering gear. Be sure to install toothed washers between the steering gear and the subframe.
