The steering system consists of a steering wheel, a steering shaft, a rack-and-pinion steering gear, and a steering drive. The steering wheel with an integrated driver's front airbag is mounted on a shaft that transmits steering movements to the steering gear. The steering column switch assembly is mounted behind the steering wheel. A coil spring, which can twist and untwist, is used to maintain contact between the airbag and the SRS control unit when the steering wheel is turned. The coil spring consists of a tape with internal conductive tracks. The steering column can be adjusted for both reach and tilt.
To facilitate the control of the car, a 3rd generation electromechanical power steering with two leading gears is installed as standard. A separate gear is added to the simple steering mechanism, acting on the steering rack and driven by an electric motor. The torque sensor on the steering shaft, acting on the steering wheel with the steering angle sensor, is located in the steering gearbox. Communication is carried out via the CAN data bus. The advantages of this design include:
- low energy consumption (the booster only uses energy when it is actually working, when the steering wheel is turned);
- hydraulic components fall off (pump, lines and power steering reservoir);
- minimal transmission of impacts to the steering wheel (for example, when driving on an uneven road);
- low noise transmission to the vehicle;
- the "active return" function helps return the wheels to a straight position.
When repairing or servicing suspension and steering components, problems often arise with loosening "stuck" bolts and nuts. The fasteners located under the bottom of the car are constantly exposed to external influences and over time they corrode and partially deteriorate. Using brute force to loosen such "stuck" fasteners is associated with the risk of damaging them. First, wet the element that cannot be loosened with a small amount of a special penetrating liquid (for example, WD-40), allowing it to soak into the rust layer well. Use a wire brush to remove external deposits from accessible areas of the threaded surfaces. Sometimes a sharp blow with a hammer on the nut through a drift helps to break up the rust filling the gaps between the turns of the threaded joint - try not to damage the threads as a result of the drift jumping off. Using a long handle when loosening "stuck" fasteners allows you to significantly increase the applied torque, but it should be remembered that the use of extensions in a set with ratchet-type drives is associated with the risk of failure of the return mechanism, as well as the possibility of injury. Self-locking nuts and fasteners damaged by corrosion or when removed during repairs must be replaced without fail. Welding and straightening are not allowed on bearings that carry the force load and on suspension components that guide the wheel.
Since most of the procedures described in this chapter are performed with the vehicle raised off the ground, you should take care in advance of options for securely fixing it in the raised position - prepare strong supports. To jack up the vehicle, use hydraulic trolley jacks - remember that the onboard jack included in the standard package is intended only for temporary jacking of the vehicle when replacing a broken wheel. The hydraulic jack can also be used to hang up some suspension components when performing a particular procedure. Before performing work, secure the vehicle to the lift legs using safety belts.
Attention: It is not permitted to carry out work under a vehicle that is held in a raised position only by means of jacks!
