Owners of a popular sedan and liftback ล koda Rapid often encounter an unpleasant knocking sound in the front suspension, which intensifies when driving over uneven surfaces. This sound usually indicates a gap in the steering rack, which is not only annoying, but also reduces the safety of driving. Ignoring the problem can lead to accelerated wear of the gear pair and costly repairs.
Many car owners mistakenly believe that steering adjustment is a complex procedure, available only in official dealerships. In fact, pulling the rack up on ล koda Rapid You can do it yourself, with a minimum set of tools and an understanding of the steering design. The main thing is to act carefully so as not to drag the mechanism and not to disrupt its operation.
In this article, we will discuss in detail the algorithm of actions, the necessary tools and technical nuances that will help you eliminate the backlash and return the steering wheel to clarity. We will also discuss the issues of diagnosis, so that you are confident in the correctness of the decision on repair.
Diagnosis of knocking and determination of the cause of backlash
Before you take up the tools, you need to make sure that the knock comes from the steering rack, and not from other suspension nodes. Often owners ล koda Rapid confuse the knock of the steering mechanism with the beating of ball supports or wear of the Silent blocks of levers. Proper diagnosis will save you time and money.
To begin with, ask the assistant to sway the steering wheel left-right while you are under the car or on the observation pit. Listen carefully to where the sound is coming from. If the knock is heard directly in the area of the steering rack, then the problem is most likely in the gap between the teeth of the gear and rack or in the wear of the bushings.
Pay attention to the nature of the knock: it can only manifest itself on small irregularities or increase with sharp turns. Also check the condition of the duster. steering rack. If the rubber is torn, abrasive could get inside, which caused accelerated wear and the need for adjustment.
- ๐ Conduct a visual inspection of the anthers for cracks and traces of lubrication.
- ๐ง Swing the steering thrusts with your hands to exclude backlash in ball hinges.
- ๐ Evaluate the condition of the Bushings of the front levers, as they often mimic the knock of rake.
Preparing tools and work area
You wonโt need complex equipment to do the adjustment work, but having certain tools is critical to success. You need to provide access to the adjusting bolt, which is located at the bottom of the steering mechanism body, often closed by plastic protection.
Lift the front of the car on the lift or use reliable stands. It is important that the wheels are in a straight position, and the steering wheel was flat. This is necessary in order to adjusting bolt He was not in a state of inoperability.
You will need: a head on 13 or 14 (depending on the year of release), a collar, a key-cracker, as well as a dynamometer key for the final puff. Donโt forget to prepare a clean rag and maybe a little penetrating lubricant if the bolt is squirrel.
- ๐ A set of heads and a rattle to remove protection and unscrew the bolt.
- ๐ง Penetrating lubricant (WD-40 or analog) for the treatment of bolt thread.
- ๐ Dynamometer key to comply with the tightening moment.
Step-by-step instructions for tightening the mechanism
First of all, remove the plastic protection of the crankcase if it interferes with access to the rack. Clean the area around the adjustment bolt of dirt and dust, so that when rotating in the thread do not get abrasive particles. Find a bolt with a hexagonal head located on the end or bottom of the steering mechanism body.
Carefully insert the key and start pulling the bolt a little bit. Don't make any sudden moves! Adjustment is carried out by moving the clamping bar, which reduces the gap between the teeth. Each movement should be minimal, literally 10-15 degrees.
After each micro-turn, lower yourself into the cabin and check the steering wheel force. The steering wheel should rotate freely, without jamming, but the backlash should disappear. If you feel that the steering wheel has become heavy or there is a knock when turning, then you have pulled the mechanism.
โ ๏ธ Warning: Excessive tightening of the adjustment bolt can lead to jamming of the steering mechanism, making driving dangerous and impossible.
โ๏ธ Check before starting work
If you have pulled the bolt, immediately loosen it by half a turn and try again. The process requires patience and gradualism. The ideal state is when the backlash is eliminated, and the steering wheel rotates evenly throughout the corner without "dead zones" and jamming.
Features of working with electric power steering
By car ล koda Rapid electric power steering (ERS) is installed, which imposes its own features on the adjustment procedure. Unlike hydraulic systems, there is no oil pressure that can compensate for the small gap, so the accuracy of the adjustment is critical.
When lifting a rail with an EUR, it is important to ensure that you do not damage the torque sensor, which is located inside the mechanism. Excessive force during tightening can deform the body and disrupt the electronics, which will lead to errors on the dashboard.
After adjustment, be sure to check the system: start the engine and turn the steering wheel several times to the stop in both directions. Make sure there is no extraneous noise and that the amplifier runs smoothly. If the panel lights up an EUR error lamp, it may require adaptation through a diagnostic scanner.
โ ๏ธ Note: If the steering icon on the dashboard catches fire after adjustment, do not ignore this - computer diagnostics are needed to reset errors and calibrate the steering wheel angle sensor.
- Yeah, constant knocking.
- Yeah, just on the bumps.
- No, it's perfect.
- Until I paid attention.
Effect of adjustment on wheel installation angles
Many owners wonder: does the collapse-descendence change after the steering rack lift? In most cases, if you just twisted the adjustment bolt and did not change the length of the steering rods, the angles of the wheel installation should not change.
However, if in the process of work you accidentally moved the steering rods or changed their position relative to the rail, the geometry of the suspension will be violated. This will lead to uneven wear of the tires and "steering" the car to the side when driving in a straight line.
For complete confidence after the work is recommended to go to the stand collapse-convergence. It takes a little while, but it ensures that the car will move straight and the tires will not wear out for a couple of thousand kilometers.
| Parameter | Value before adjustment | Action | Result |
|---|---|---|---|
| Steering wheel play | 15-20 mm | Bolt lift | Removed (0-3 mm) |
| Steering force | Low | Rotation control | Uniform |
| Sound in motion | Knock | Checking the pit | Gone. |
| Work of EUR | Norm | Test run | No errors |
Service life and prevention
Correctly adjusted steering rack on ล koda Rapid It can last tens of thousands of kilometers. However, regular checks of the suspension condition will help you notice new problems in time. It is recommended to inspect every 10-15 thousand kilometers of run.
Keep an anther seal intact. Even a small crack can cause dirt and moisture to get in, which will quickly disable the mechanism. When replacing anthers, partial disassembly of the rack is often required, which is an excellent opportunity to check the condition of the internal nodes.
Donโt forget about driving style: aggressive driving on bad roads significantly reduces the life of the steering mechanism. Try to skip deep holes and not run into curbs at high speed to prolong the life of the suspension.
- ๐ก Regularly inspect the anthers for tears and scuffs.
- ๐ฃ Avoid sharp blows to the steering wheel when parking on curbs.
- ๐ง Check the condition of the oils and the presence of traces of lubrication leakage.
Frequent mistakes when self-adjusting
One of the most common mistakes is trying to tighten the rack without first diagnosing. If the knock is caused by wear of the bushings or the jagged pair itself, a simple tightening of the bolt will not help and may even make the situation worse by causing jamming.
Another mistake is the use of an inappropriate tool that tears the edges of the adjustment bolt. In this case, you will have to resort to more sophisticated methods of bolt extraction, which increases the repair time and the risk of damage to the case.
It is also worth noting that some owners try to adjust the rail with the hung wheels, not taking into account that when the car is grounded, the load on the mechanism changes. It is ideal to check the result on the ground where the suspension is in working condition.
What to do if the bolt is broken?
If the edges are torn, try using an extractor or gently sawing the head with a Bulgarian to remove the locking ring and remove the mechanism, but this requires high qualification.
Do not forget about the moment of tightening. Too weak puff will not remove the knock, and too strong will lead to rapid wear of the teeth. Use a dynamometer key if possible, or act on the principle of "sense of proportion".
Before starting work, be sure to remove the negative terminal from the battery to avoid accidental switching on of electronics or circuiting, although the risk is minimal when working with mechanics.
โ ๏ธ Warning: If you are not confident in your abilities or have not found the source of the knock, it is better to entrust the work to professionals. Mistakes in steering can cost your health.
Conclusion and outcome
Steering rail lift on ล koda Rapid This is a very easy task for a car owner with basic repair skills. The main thing is to be careful, act consistently and not rush. The right setup will give you comfort and confidence behind the wheel.
Remember that steering is a system that directly affects safety. Regular monitoring of the suspension condition and timely elimination of backlashes will help to avoid major breakdowns and expensive replacements of units.
If after fulfilling all the recommendations, the knock has not disappeared or the steering wheel force has become too high, it may be necessary to replace the bushings or completely replace the steering mechanism in the assembly. In this case, do not delay the visit to a specialized service.
Adjustment of the steering rack is a balance between eliminating the backlash and maintaining the ease of rotation of the steering wheel, which must be achieved by micro-rotations of the bolt.
Frequently Asked Questions
Do I have to do a break-down after a rake lift?
If you only twisted the adjusting bolt and did not change the length of the steering rods, then the collapse-convergence does not need to be changed. However, for confidence, it is recommended to check the angles of installation of the wheels.
How many turns do you need to make a bolt?
There is no fixed number of turns. Adjustment is made "by ear" and by feeling on the steering wheel. Usually it is 1/4 or 1/2 revolution, after which you need to check the result.
Can I adjust the rake to cold?
Adjustment can be carried out at any temperature, but it is better if the car is warmed up, as the rubber and metal expand, and the gaps can vary slightly. The main thing is that the steering wheel should be in a straight position.
What to do if after the lift lighted the lamp of the steering error?
This may mean that the steering wheel angle sensor has left the calibration range. It is necessary to connect a diagnostic scanner and perform the procedure of adaptation (calibration) of the steering wheel.
How long does this procedure take?
If there is a pit or lift and the necessary tools, the procedure takes from 30 minutes to 1 hour, including checking the result and cleaning the workplace.
