Hyundai Getz>> Steering>> Survey and steering check
At each maintenance service of the car check a condition of a protective cover of the steering mechanism, caps of hinges of draughts and density of their landing. Them it is necessary
To replace in the presence of cracks, ruptures and other defects breaking tightness.

       THE NOTE
All amplifiers of a steering publish different sounds at work. One of the most widespread sounds is hissing at steering wheel turn on the standing car. This sound is especially well audible at turn of a steering wheel with simultaneous pressing a brake pedal. This sound is not connected at all with working capacity of a steering. Do not replace the distributor if only the hissing sound does not become too loud. The new distributor will publish too weak noise, and malfunction is eliminated by such replacement not in all cases.

Be convinced that at rectilinear position of wheels of the car the steering wheel spoke settles down horizontally. Otherwise define a cause of defect and eliminate it.
Turning for a steering wheel from an emphasis against the stop, check up visually and on hearing the following:
– Reliability of fastening of a steering column, the steering mechanism and a steering wheel;
– Absence of a backlash in резинометаллических hinges and hinges of steering draughts, and also in connections elastic муфты a wheel shaft;
– Reliability of an inhaling and latching of bolts of fastening of bent for the helmsman рейке and nuts of fingers of spherical hinges;
– Absence of jammings and the hindrances interfering turn of a steering wheel.
If knocks and jammings are found out, disconnect cross-section draughts from rotary levers of telescopic racks of a suspension bracket and repeat check. Having convinced that knocks and jammings proceed from a steering, remove it from the car and check up backlash size between an emphasis рейки and a nut. As much as possible admissible backlash between an emphasis and a nut of 0,2 mm. If necessary replace the worn out details and adjust a backlash between an emphasis and a nut.

Check of a free wheeling of a steering wheel
Establish a steering wheel in position of rectilinear movement and start up the engine.
Check up a steering wheel free wheeling on its circle.
The steering wheel free wheeling should be 0–30 mm.
At excess of the specified value check up connections between shaft of a steering and a steering drive.

Check of angles of rotation of wheels

Fig. 5.1. Check of angles of rotation of wheels


Establish the car forward wheels on the rotary stand and check up angles of rotation of wheels (fig. 5.1).
Angle of rotation of wheels (the car without loading):
The internal..... 37°±1°30'
The external..... 33°03'
If angles of rotation of wheels do not correspond to the specified values, adjust it is similar-denie wheels and again check up angles of rotation.

Check of a condition of tips of steering draughts
Check of the moment of resistance проворачиванию fingers of spherical hinges of tips of steering draughts

Fig. 5.2. A detachment of steering draught from a rotary fist


By means of the special adaptation disconnect steering draught from a rotary ku-varnish (fig. 5.2).
Be convinced of absence of an excessive backlash in the spherical hinge of a tip of draught, not-how many time having turned the hinge for a finger circular motions.

Fig. 5.3. Check of the moment of resistance проворачиванию a hinge finger


Wrap a nut of fastening of a finger of the hinge of draught and check up the resistance moment проворачиванию a hinge finger (fig. 5.3), it should be equal 0,5–2,5 Н·м.
If the resistance moment проворачиванию exceeds the specified top limit, replace a tip of steering draught.
If the resistance moment проворачиванию a finger of the hinge less than the specified bottom limit, check up a backlash in the hinge and if necessary replace it.

Check of effort of turn of a steering wheel on the standing car
Put the car on an equal horizontal platform, establish a steering wheel in position of rectilinear movement.
Increase frequency of rotation of a cranked shaft to (1000±100) mines-1.

       THE NOTE
After check lower turns of the engine to idling turns.

Fig. 5.4. Check of effort of turn of a steering wheel


By means of spring scales check up effort of turn of a steering wheel, turning it on 1,5 turns in both parties (fig. 5.4).
The effort of turn of a steering wheel to the motionless car should make 29 Н (3,0 кгс).
During steering wheel rotation be convinced of absence of sharp changes of effort.
At the raised effort of turn of a steering wheel execute following checks and adjustments:
– Check up spherical hinges of tips of steering draughts and protective covers on presence of cracks or damages;
– Check up the moment проворачивания приводной gear wheels of the steering mechanism and spherical hinges of tips of steering draughts;
– The moment проворачивания the spherical hinge.
Check of returning of a steering wheel in position of rectilinear movement
Check up spontaneous returning of a steering wheel on following parametres.
At performance of the moderate or sharp turns effort to a steering wheel and its returning should be identical in the left and right turns.
After steering wheel turn on 90 ° and its keeping within several seconds during car movement for the speed of 35 km/h the released steering wheel should turn not less than on 70 ° towards neutral position.

       THE NOTE
At very sharp turn of a steering wheel the raised resistance can quickly be felt. It is not a malfunction sign, and is connected with some decrease in giving of the pump of the hydraulic booster.

Check of a condition of the hydraulic booster

Fig. 5.5. Check of a deflection of a belt of a drive of the pump of the hydraulic booster


Check up a deflection of a belt of a drive of the pump of the hydraulic booster, having pressed it with effort 98 Н (10 кгс) in a place specified by an arrow on fig. 5.5.
The deflection of a belt of a drive of the pump of the hydraulic booster should be 6–9 mm.
At discrepancy of a deflection of a belt to the specified limits adjust a belt tension, as set forth below.
