Diagnostics of malfunctions of a steering

It is excessive люфт a steering wheel

Spherical hinges of components of a steering drive are worn-out, or landing weakened them. Tighten fixture, or replace defective components.

The steering mechanism is worn-out, or its adjustment is broken. If after adjustment performance люфт a steering wheel does not settle into shape, it is necessary to make major maintenance of the steering mechanism with replacement of defective components and final adjustment.

Plugs of a cross-section jet bar are worn-out. Replace plugs.

Landing of a soshka of the steering mechanism on sector to a shaft weakened. Tighten a fixing nut.

Weakened bolts of fastening of assembly of the steering mechanism (see an accompanying illustration). Tighten fixture.

The flexible coupling or kardanny hinges of a steering shaft are faulty. Replace defective components.

Люфт components of a steering drive it is best of all shown at the car lowered on forward wheels. Ask the assistant to rotate a steering wheel and visually estimate degree of wear of components of a drive of a steering. If the weak point of the steering mechanism is obviously shown at the rectilinear provision of forward wheels of the car, mechanism adjustment most likely is broken. If люфт does not disappear after adjustment performance, the steering mechanism is necessary for removing for work of major maintenance.

Too hard course of a steering wheel takes place

Too poorly, or tires are pumped non-uniformly up. Check pressure of a rating, in case of need make adjustment.

Level of hydraulic liquid fell in the tank of system of hydrostrengthening of a wheel. Check system on existence of signs of leaks, make necessary corrections and/or replacements. Add liquid to demanded level.

Adjustment of the steering mechanism is broken. Check, execute necessary adjustment.

There is a jamming of a steering shaft. Find out the jamming reason, replace defective components.

The steering pump does not provide a due pressure. Check a condition and effort of a tension of a driving belt of the pump, and also level of hydraulic liquid in the tank of system of hydrostrengthening. In case of need replace the pump.

Check sufficiency of depth of a pattern of protectors and correctness of pressure of a rating of tires of both forward wheels.
Before starting check of geometrical parameters of a steering drive, estimate degree of wear of components of the forward bridge.

The car at rectilinear movement on a horizontal surface withdraws in one of the parties

Tires are non-uniformly worn-out or pumped up. Check a condition and pressure of a rating of tires. In case of need make replacement of tires or correction of pressure.

Adjustment of corners of installation of forward wheels is broken. Check, make adjustment. Brake mechanisms of forward wheels "are taken". Check supports on existence of signs of leakages of brake liquid and jamming of pistons. Replace defective components.

Components of a forward suspension bracket or forward beams of the chassis are damaged. Check. Replace defective components.

If tires of forward wheels of the car are found in a satisfactory condition, lift a front of the car and rotate both lobbies of a wheel for check of brakes on "prikhvatyvaniye".
For check of corners of installation of forward wheels measure distances from the center of disks of forward wheels to the center of disks of back wheels from both boards of the car. At the rectilinear provision of forward wheels results of measurements should coincide.

Lateral palpation or the angular oscillating motion of operated wheels arising on low speeds of movement (шимми) takes place

Weakened fastening of the steering mechanism. Make adjustment or major maintenance of the steering mechanism.

The shock-absorber of the steering mechanism is faulty or its rubber plugs are destroyed as a result of material aging. Remove the shock-absorber and check its condition (see an accompanying illustration). in case of need replace rubber plugs.

Are non-uniformly worn-out, or tires are pumped incorrectly up. Check a condition and pressure of a rating of tires. In case of need make replacement of tires or correction of pressure.

Balancing of wheels is broken. Check, отбалансируйте.

Damage of components or violation of geometry of a front of the car takes place. Check, execute necessary corrections or adjustment of geometrical parameters.

Bearings of forward wheels are worn-out, or their adjustment is roughly broken. Check a condition of bearings, modify a pretightness, or replace bearings.

Adjustment of corners of installation of forward wheels of the car is broken. Check, make necessary adjustment.

Spherical hinges are worn-out, or landing weakened them. Check, tighten fixture, or replace defective components.

Check a condition of components of a steering drive. Lift a car front for check and adjustment of a pretightness of wheel bearings. For check of a condition of bearings serially pull wheels in the cross-section direction, having grasped them above and below. Люфт should be absent absolutely.

Controllability violation by the car or loss of course stability takes place

Adjustment of corners of installation of forward wheels is broken. Check, in case of need make adjustment.

The protector of tires of forward wheels is wiped. Check, in case of need replace tires.

It is excessive люфт a steering drive. Check, replace worn-out components, in case of need make adjustment of the steering mechanism.

It is exceeded, or pressure of a rating of tires is belittled. Check, modify pressure.

Weakened, or the pretightness of bearings of naves of forward wheels is incorrectly exposed. Check, execute necessary adjustment.

It is excessive люфт in spherical hinges. Check, replace defective components. Also check a condition of covers of spherical hinges.

Serviceability of functioning of the power steering is broken

The driving belt of the steering pump is torn off, or adjustment of effort of its tension is broken. Check a belt condition (see an accompanying illustration), make replacement, or tighten a belt with demanded effort.

Liquid level fell in the tank of system of hydrostrengthening of a wheel. Check, whether there are no leakages of liquid, make necessary repair, or replace defective components. Add liquid to demanded level.

The steering pump does not provide a due pressure. Check, in case of need replace the pump.

Assembly of the hydrostrengthened steering mechanism is faulty. Remove assembly, make its major maintenance.

Leakages of hydraulic liquid take place

The tank of hydraulic liquid, the steering pump or the steering mechanism are damaged, or weakened their fastening. Check, tighten fixture, or replace defective components.

Are damaged, or hydraulic hoses are destroyed as a result of material aging. Check, replace defective hoses.

Attentively check on existence of signs of leaks all hydraulic lines of system of hydrostrengthening of a wheel (see an accompanying illustration).

Noise of the hydrostrengthened steering mechanism take place

The driving belt of the steering pump is damaged, or weakened its tension. Adjust effort of a tension of a belt, or replace it.

Air got to hydraulic system. Pump over system.

Hoses and tubes of hydraulic lines are incorrectly connected, or weakened their shtutserny connections. Connect lines correctly, tighten shtutserny connections.

Basic arms of the steering pump are displaced, or weakened their fastening. Correct the provision of arms, tighten fixture.

Violation of passableness of hydraulic lines also can be at the bottom of emergence of noise in the steering mechanism. Attentively examine hoses and tubes of lines on existence of excesses and twisting.
