Problems with steering on cars Skoda Fabia First and second generation often manifest as extraneous noises, knocking or a complete lack of assistance when turning wheels. Owners of these models are faced with the fact that the steering wheel becomes heavy, especially at low speeds, which not only reduces comfort, but also poses a direct threat to traffic safety.
System power steering (GUR) is a complex mechanism consisting of a pump, a steering rack, a distributor and connecting hoses. Failure of any of these elements requires an immediate response, as operating a vehicle with a faulty amplifier can lead to a steering jamm or road emergency.
The main symptoms of a malfunction of the GUR system
The first sign that something is wrong with the amplifier system is a change in the sound background when the engine is running. A characteristic howl or hum that is amplified when the steering wheel is twisted to the point, most often indicates problems with the pump or low level of working fluid.
Sometimes the problem lies not in the pump, but in the steering mechanism itself. If you feel a knock or beat through the steering wheel when passing irregularities, this is a sure sign of wear of a geared pair of rakes or support bushings. In such cases steering rack repair It is inevitable if you want to keep the controllability at the proper level.
Another alarming signal is the leakage of fluid. Under the car or on the suspension elements may appear red or brown traces of oil.
- 🔴 Leak through the helms of the steering slat
- 🔴 Cracks on high-pressure hydraulic hoses
- 🔴 Wear of the sealing rings in the pump
Diagnostics of the hydraulic booster pump
The pump is the heart of the entire hydraulic system, and its failure paralyzes the amplifier. When diagnosing, pay attention to the level of fluid in the expansion tank - it should be between the labels MIN and MAX. If the level is critically low, the system can capture air, which causes characteristic gurgling and noise.
The pump itself may have mechanical damage to bearings or wear of rotor blades. To check, remove the drive belt and manually scroll the pump pulley - it should rotate smoothly, without jamming and backlashes. If you hear a crunch or feel resistance, GUR pump replacement necessary.
It is important to check the drive belt. A weakened or worn belt will slip, which will prevent the pump from creating the necessary pressure.
- ✅ Inspect the belt for cracks and scuffs
- ✅ Check the tension of the belt with a special strain gauge
- ✅ Replace the slack if it is worn out
- Pump hum
- Knocking in the steering wheel
- Liquid leak
- Heavy steering
Algorithm of replacing the steering rack
Replacement of the steering rail by Skoda Fabia It is a time-consuming procedure that requires a certain set of tools and skills. First, you need to dismantle the wheels and unscrew the steering thrusts from the swivel levers. Be very careful not to damage the anthers of the ball supports.
Next, you need to disconnect the hydraulic hoses from the rack. Be sure to substitute the container under the connection place, since when unscrewing the hoses, a significant amount of working fluid will leak out. Then unscrew the bolts of the attachment of the reiki itself to the subframe and carefully remove the knot.
Before installing a new or repaired rail, be sure to check the condition of the subframe silent blocks.
⚠️ Warning: Never twist the steering rack to the point when checking the pump on a rented car - this can instantly break the seals inside the distributor.
☑️ Preparing to replace the rack
Popular causes of breakdown and their elimination
One of the most common reasons for failure of GUR in the Fabia is the use of poor-quality liquid or late replacement. Over time, the oil oxidizes, loses its lubricating properties and clogs small channels in the distributor. This leads to rudder jerks and noise.
The second common problem is the wear of the cog shafts of the gear. Through them, oil begins to ooze, which reduces pressure in the system. In some cases, simply replacing the ossels helps, but a complete bulkhead of the reiki is often required.
- 💧 Metal shavings contamination of the system
- 💧 Corrosion of the rod mirror due to water ingress
- 💧 Wear of distribution seals
What if the reiki is jammed?
If the steering wheel has stopped rotating, do not try to turn it by force. This can lead to breakage of the steering shaft or damage to airbags. Call the tow truck immediately, as further movement is impossible without the help of a tugboat.
Compatibility table for liquids and spare parts
For proper repair, it is important to use original or certified spare parts analogues. Below is a table with the basic parameters of liquids and articles suitable for different generations. Skoda Fabia.
| Parameter | Meaning | Note |
|---|---|---|
| Liquid type | Pentosin CHF 11S | Standard for the VW Group |
| Pump articulation | 1J0 423 129 | Suitable for Fabia I |
| Reiki articulation | 6R0 422 065 | Suitable for Fabia II |
| System volume | 1.5 liters | In view of the replacement |
Procedure for pumping the system after repair
After fluid replacement or reiki repair, it is imperative to remove air from the system. Start the engine and spin the steering wheel from point-blank to point-blank several times, without holding the steering wheel in extreme positions for more than 2-3 seconds. This will help the pump push air into the expansion tank.
Check the fluid level again and add if necessary. The air in the system can cause knocking and loss of effort.
⚠️ Attention: When pumping, watch the temperature of the liquid - it can get very hot if you turn the steering wheel on the working engine for a long time without the movement of the car.
Proper pumping of the system is the key to smooth steering and the absence of extraneous noise.
Cost of repairs and choice of service
GUR repairs can range from simple fluid replacement to overhauling the rack. If the problem is in the pump, the cost of replacement will include the knot itself and the work of the wizard. When repairing the rail, the price depends on the degree of wear and the need to replace the remplekt or the entire body.
Many owners choose a bulkhead reiki with replacement of glands and bushings, as it is cheaper to buy a new original part. However, it is important to find a specialized service that has a stand for checking hydraulics.
- 🛠️ Diagnosis - from 1000 rubles
- 🛠️ Replacement of pump - from 3000 rubles + spare part
- 🛠️ Repair of the rack - from 5000 rubles + remake
Before starting the repair, be sure to take a picture of the connection scheme of the hoses and the location of the bolts - this will save time during assembly and help avoid errors.
Why is the GUR pump going off?
The hum is most often caused by a lack of fluid, air intake, or wear of the bearings of the pump itself. Also, the cause may be a weakened belt drive.
Is it possible to drive with a faulty power steering?
Technically possible, but the steering wheel will become very heavy, especially when parking. This increases the risk of an accident and the load on the steering mechanism, which can lead to its complete destruction.
What liquid to pour in GUR Škoda Fabia?
It is officially recommended to use liquid Pentosin CHF 11S. Other types of fluids can cause the rubber seals to break down and the system to fail.
How long does it take to repair a rack?
Replacement of the slat takes 2 to 4 hours depending on the model and access to the mount. Major repairs with bulkheads can take up to 8 hours.
Remember that timely maintenance of the power steering system will save you from expensive repairs and ensure safety on the road. Regular check of the level and condition of the fluid, as well as attention to the appearance of extraneous sounds will help to identify the problem at an early stage.
Do not delay your visit to the service at the first sign of a malfunction. Removing a shallow leak or replacing a worn-out pump will be significantly cheaper than replacing the entire steering rack or recovering from an accident due to a steering failure.
⚠️ Warning: If you notice a sharp increase in back lift steering or its jamming, immediately stop the car and call for help, as further movement can be dangerous.
Taking care of the steering is taking care of your life and the lives of those around you. Competent approach to repair and use of quality spare parts will ensure long and reliable service of your car Skoda Fabia.
