GENERAL INFORMATION

REASON
WAY OF ELIMINATION
From the steering mechanism hissing is listened
The noise accompanying normal operation of the steering drive are allowed. Hissing is the most characteristic sound which is well listened at the parking. This sound is not a consequence of malfunction of the steering mechanism and can be published when the wheel turns in extreme situation or at slow rotation of a wheel at the parking of the car
Weak hissing is allowed. If hissing moderate, then the valve it is not necessary to change. Replacement of the valve as a rule does not lead to elimination of the hissing sound. Examine places around rivets of the elastic coupling. The steering shaft and a gear wheel have to be correctly combined that the elastic coupling rotated without deformations at turn of a wheel. At any contact of metal details via the elastic coupling in salon the hissing sound will be transmitted.
From the steering mechanism the deaf knocks (reminding clicks) are listened
Weakening of fastening of steering transfer
To tighten connections.
Easing of steering drafts
To check a condition of tips of drafts, if necessary to replace.
The tube of a hydraulic actuator touches surrounding details
It is forbidden to expose a tube, to turn in.
Weakening of a shaft of a bipod at turn from average situation (at turns the weak knocks connected with small increase in a side play of a shaft of rather average situation that is provided by a design are allowed)
It is forbidden to adjust the steering mechanism and to reduce gaps against norm for the purpose of weakening of such knocks. The bipod shaft side play exceeding norm is eliminated with adjustment of the steering mechanism.
Weakening of a bipod on a shaft
To tighten a bipod nut with the set moment.
Sharp sound at turn or at return of a wheel to a starting position
Damage of a sealing ring of a quencher of fluctuations
To replace a ring.
The wheel does not come back to a starting position
Pressure in tires differs from norm
To restore pressure.
Lack of lubricant in details of a forward suspension bracket
To grease drafts and tips of drafts.
Zadevaniye of a coupling flange for a cap of the adjusting screw of the steering mechanism
To weaken the pulling together bolt and to rearrange the coupling.
Wrong combination of the steering mechanism with a steering column
To eliminate.
Violation of angles of installation of wheels
To check and adjust the angles of installation of wheels.
Jamming of steering draft
To replace hinges of tips of drafts.
Jamming of spherical hinges of levers of a suspension bracket
To replace spherical hinges.
Zadevaniye of a wheel for the case
To improve wheel situation.
Bearings of a steering shaft are drawn or taken
To replace bearings.
Sticking or contamination of a cylindrical zolotnik
To clear or replace a zolotnik.
Wrong adjustment of the steering mechanism
To remove the steering mechanism and to adjust.
The return hose of the hydraulic booster is pressed
To replace a hose.
The car takes away aside (to check at two arrivals in opposite directions to exclude influence of wind and a paving)
Violation of angles of installation of wheels
To check and adjust the angles of installation of wheels.
Disbalance of the valve of the steering mechanism (in this case the wheel turns easily in the direction of leaving of the car, and in an opposite direction rotates under the influence of normal or a little bigger effort)
To replace the valve.
At bystry turn of a wheel in both parties instant resistance is felt
Low level of liquid
To restore level.
Slipping of a belt
To adjust a tension or to replace a belt.
Strong internal leak
To check pressure at the pump exit.
Twitching of a wheel at turn on the working engine, especially during the parking with the working engine
Low level of liquid
To restore level.
Weakening of a belt
To adjust a tension.
Zadevaniye of steering draft for the oil pallet
To eliminate.
Insufficient pressure of the pump
To check pressure, if necessary to replace the reducing valve.
Sticking of the control valve
To check a condition of the valve, if necessary to replace.
The raised side play on a steering wheel
Hit of air in a hydraulic actuator
To add liquid and to remove air with turn of a wheel. To check an inhaling of unions.
Weakening of fastening of the steering mechanism
To delay connections by a dynamometer key.
Wear of tips of steering drafts
To replace.
Wear of the dish-shaped valve
To replace.
Insufficient preliminary tightness of the persistent bearing at adjustment
To remove the steering mechanism and to adjust.
The raised side play in gearing of gear wheels of the steering mechanism
To remove the steering mechanism and to adjust.
The complicated rotation of a wheel, strengthening of the steering drive on wheels is not felt
Weakening of a belt
To adjust a tension.
Low level of liquid (when falling level of liquid noise from the pump increase)
To restore level.
Wrong combination of the steering mechanism with a steering column
To eliminate.
Zadevaniye of a coupling flange for a cap of the adjusting screw of the steering mechanism
To weaken the pulling together bolt and to rearrange the coupling.
Low pressure in tires
To restore pressure.
Liquid foaming, falling of level, low pressure of the pump
Air hit, loss of liquid because of leak in the pump
To find leaks and to eliminate. To remove air. Air gets a hydraulic actuator under operating conditions at very low temperature when the level of liquid is lower than norm. If level normal, but liquid foams, then remove the pump and disconnect a tank. Check a condition of the case and a cap. At detection of cracks replace the pump.
Weak effort from the pump of a gidrousiditel
The control valve is faulty
To clear the valve or to replace.
Distortion of a press plate concerning a cam
To eliminate.
Weak effort from the steering mechanism
Losses of pressure because of wear of a piston ring or wear of the cylinder
To sort and check a condition of a ring and the cylinder.
Leakage of rings of the valve and epiploon of the valve
To remove, sort and replace consolidations.
The chirping noise from the pump
Weakening of a belt
To adjust a tension.
The squealing sound proceeds from a belt (it is well listened at turn of a wheel against the stop or at the long parking with the working engine)
Weakening of a belt
To adjust a tension.
Deaf sound of low tone from the pump
The increased return pressure in hoses or the steering mechanism caused perezhatiy hoses
To eliminate perezhaty, if necessary to replace details.
Deaf sound of low tone (it is distinctly listened at the long parking with the working engine)
Teases on a press plate, a persistent plate or a rotor
To replace details and to wash out system.
Wear of a cam
To replace worn-out details.
Scratches in the pump
Low level of liquid
To restore level.
Air hit. Untight connection of hoses
To tighten unions with the set moment. To remove air, rotating a wheel in both parties against the stop.
