The role of the steering is to direct the wheels in tandem with the movement of the steering wheel and is one of the most important components of the car.
There are four types of steering boxes, i.e. hydraulic, electro -hydraulic, electronically assisted and mechanically assisted.
The most serious situation, we can also say fatal, is satisfied when the steering system is a shortage, because it endangers both the life of the driver and the other traffic participants, for this reason it is good not to neglect the minimum signal that could suspect the problems in the direction.
The main components of the steering system are:
- Steering wheel
- Ax Volan
- Directorate column
- Management box (mechanical, servant-assistant, serving, electric)
- Semi-set direction
- The servant pump (belt or electronic acting)
- Levier direction
- Beieleta management
- Cap coff
Directorate of the defective symptoms
- The direction goes hard
- Turn on in the direction
- Beat on the steering wheel
- Noises in power steering
- Work fluid losses – Fluid loss is not evident as in other cars systems, no point is seen under the car, but by carefully examining the system we will see humid, soaked in oil.
- The wheels smile when they are transformed to the maximum
The first thing to do in such a situation is to enter a parking lot and check how it follows:

– Place the car on a perfectly flat surface
– move the steering wheel to all directions; In the situation in which an excessive game appears between the steering wheel and the steering blow, it is certainly a problem with this component of the steering system
– pull or push the steering wheel into different parts; If there are great games, the problem comes from elastic joints or joints
– With the engine started, turn left or completely to the right and observe if there is excessively behind the wheel, if we hear strange noises or vibrations. When identifying these symptoms, it is necessary to enter service to change the steering box.
Power steering defects:
In the following table, 6 of the most common symptoms that lead to the following defects are centralized:
Nr CRT | Symptoms | GUILT |
1 | Beat in the steering system | • wear of the joint of the end of the steering bar • Weakening of the spherical articulation of the bar’s head |
2 | Sliding the steering wheel | • wear of the joint of the end of the steering bar • wear or destruction of the grooved axis • Deviations to the performance of the wheels |
3 | Bud | • wear of the joint of the end of the steering bar • wear of the transmission pair (gear) • wear of the axis of the axis |
4 | Narrow steering wheel | • In violation of the wheel alignment corner • Slide the accessory belt • Low level of work fluid • clog the actuators |
5 | Noise in power steering | • wear of the pump tree bearing • Slide the accessory belt • Low level of work fluid |
6 | Liquid losses | • Use of the sealing of the steering mechanism • damaged pipes |
The axis in the steering of rust, producing oil leaks.Causes that lead to the failure of the steering box:
- Roads with bumps, Fosse, boulders, gravel, destroyed components from the steering box
- The wear of the transmission pair (Rack march)
- The wear of the steering system seal
- Destroy the axis bearing
- Wear of the joint of the end of the steering bar
- The wear of the spherical articulation of the bar’s head – one of the most common defects
- Maintenance and unqualified repairs
- Lower quality working fluid
- Deviations from the performance of the wheels (tire pressure, balance wheels, worn tires, worn bearings)
Symptoms defect of the Bieletta Department
The steering rod is made up of a metal bar equipped with an oscillating end. It connects between the steering box of a car and the end of the Pivetta bar. There are two connections: one towards the wheel that turns right and one towards the wheel that turns left.
Signs as bellboards are defective:
- Damaging the tires of the tires
- Specific noises on the transfer of bumps
- The geometry of the disturbed wheels
- Loss of precision of the management of the transfer.
Bielet defects:
- deformations
- flexion or breakage
- The car is oscillating
- The car pulls on one side
In order to avoid lacking the steering system, we advise you to control it in an authorized service, every time it is preparing to do the inspection, thus preventing any serious consequences deriving from neglecting the specific signals of some problems.
