Owners Skoda Rapid Models of 2017 often experience a characteristic knocking sound when driving over uneven surfaces, which many people mistakenly mistake for a shock absorber malfunction. In fact, most often the problem lies in support bearing front suspension, which is a critical component for ensuring the smoothness and handling of the vehicle.
This element absorbs axial and radial loads, allowing the shock absorber to rotate when the steering wheel is turned. In the conditions of Russian roads, where the quality of the coating often leaves much to be desired, the service life of the part is significantly reduced, requiring the car owner to be attentive to diagnostics and timely replacement of support.
How to recognize a malfunction in the early stages
The first and surest sign of wear is a specific metallic knock that occurs when driving over speed bumps or deep holes. This sound is usually heard on one side, but when wear is critical it can appear on both sides, creating the illusion of a general suspension problem.
The second important symptom is difficulty turning the steering wheel. If you notice that the steering wheel returns to its original position after turning with a delay or with a noticeable effort, this is a direct indication that support bearing lost its mobility and became jammed.
Sometimes the malfunction is accompanied by a squeaking noise when turning the steering wheel while the car is stationary. This occurs due to lack of lubrication in the working area or destruction of the separator, which leads to metal-to-metal friction.

Design features of the unit on Rapid 2017
By car Skoda Rapid The 2017 model year uses a MacPherson strut suspension, where the support bearing is integrated into the upper shock absorber cup. This is a complex structure consisting of a metal housing, a rubber-metal cushion and the rolling bearing itself.
A special feature of this unit is that it is designed for high dynamic loads typical for urban use. Over time, the rubber part hardens and cracks under the influence of temperature changes and reagents, which breaks the seal and leads to dust getting inside.
The manufacturer does not always provide for the possibility of separately replacing only the bearing, although this is often done in service practice. However, if the rubber support is heavily worn replacement assembly is a more reliable solution that guarantees the durability of the unit.
⚠️ Attention: Ignoring a faulty support bearing can lead to destruction of the upper glass of the car body, which will require expensive body repairs and welding work.
Selection of spare parts: original or analogues
When choosing a spare part for Skoda Rapid It is important to understand the difference between original parts and high-quality analogues. Original bearing from Skoda (VAG) features ideal balancing and long-lasting lubrication, but is significantly more expensive.
Among the proven analogue manufacturers, we can highlight brands SACHS, KYB and SNR. These companies supply components to the assembly line, so their products are often not inferior to the original in quality, and sometimes even surpass it in terms of wear resistance.
Avoid buying cheap parts from unknown markets as they are often made from low quality steel and rubber. Saving 2,000 rubles on such a part can result in a repeated replacement in six months and damage to the shock absorber.
| Manufacturer | Part type | Approximate price (RUB) | Features |
|---|---|---|---|
| Skoda (VAG) | Original | 8 500 - 12 000 | Maximum compatibility, long service life |
| SACHS | Analog (Premium) | 4 500 - 6 000 | Excellent quality, often comes with a support |
| KYB | Analogue | 3 800 - 5 200 | Reliability, good lubrication |
| SNR | Analogue | 3 500 - 4 800 | High manufacturing precision |

Step-by-step replacement instructions
Replacing the support bearing with Skoda Rapid - a task of moderate complexity that requires special equipment, including a spring puller. Without this tool, work is extremely dangerous due to the high spring tension.
First you need to dismantle the wheel and unscrew the nut securing the shock absorber rod in the engine compartment. Then you need to loosen the shock absorber mounts from below to remove the strut assembly from the wheel arch.
Next, the stand is clamped in a vice, and using a puller, the spring is carefully compressed until the tension is removed from the support. After this, the bolts securing the upper support are unscrewed, and the old part is dismantled to be replaced with a new one.
- 🔧 Be sure to use a spring remover to safely disassemble the strut.
- 🛠️ Check the condition of the shock absorber itself and the spring before installing new parts.
- 🔄 When assembling, observe the bolt tightening torque specified in the service book.
☑️ Preparing to replace the support
⚠️ Attention: Do not try to compress the spring using the shock method or without a special puller - this can lead to injury or destruction of the spring, which will fly out with enormous force.
What to do if the bolts are stuck?
If the lower strut bolts are stuck, do not apply excessive force immediately. Use a penetrating lubricant (like WD-40 or Liquid Wrench) and let it sit for 15-20 minutes. You can gently tap the joint with a hammer to destroy the rust layer, but avoid hitting the threaded parts of the shock absorber rod.
Consequences of incorrect installation
One of the most common mistakes during replacement is misalignment during assembly of the unit. If the upper support is installed skewed, this will lead to rapid wear of the rubber part and the appearance of a knocking sound after just a few thousand kilometers.
It is also critical not to overtighten the shock absorber rod nut. Excessive force can deform the bearing, blocking its rotation. This will immediately affect handling and create unnecessary stress on the steering rack.
Another common problem is ignoring the condition of the boot. If you do not install a new boot and bumper when replacing, then dirt and moisture will quickly get into the bearing, which will reduce its life to a minimum.
Before the final tightening of all the bolts of the rack, make sure that the car is on wheels and under load so that the rubber support is not twisted in a neutral position.
Diagnostics after repair and wheel alignment
After the bearing replacement necessarily It is necessary to carry out the procedure of adjusting the angles of installation of wheels (fall-fall). Any intervention in the suspension changes the geometry, and without correction, it will lead to uneven wear of the tires.
It is also recommended to check the steering. The steering wheel should rotate smoothly, without jamming, and it is easy to return to the center when leaving the corner. If these conditions are not met, it is possible that the new part is defective or installed incorrectly.
The first 500 kilometers after replacement should be avoided aggressive driving and deep pits to allow the rubber and lubricant in the new bearing to adapt to working conditions.
Replacement of the bearing should always be accompanied by checking the geometry of the suspension and installation of descent-breakdown, otherwise new parts will quickly fail.
Frequently asked questions from Rapid owners
Do I need to replace bearings in pairs?
It is advisable to change them with a pair, even if only one is defective. Wear occurs evenly on both sides, and the old support on the other side may fail very soon, which will require rework and the cost of paying for service.
Can you replace the old bearing, leaving the old support?
Technically, this is possible if the rubber part of the support does not have cracks and deformations. However, in practice, it often turns out that the dismantling of the old bearing damages the rubber support, so it is easier and more reliable to change the assembly.
How often should the condition of the supports be checked?
It is recommended to check at each scheduled maintenance, as well as at the first symptoms of malfunction. The average life of these parts is 60-80 thousand kilometers, but it depends on the operating conditions.
Why does it knock even after the replacement?
If the knocking remains, perhaps the problem is not in the bearing, but in the shock absorber itself, stabilizer sleeves or ball supports. It is also possible that the new part was installed incorrectly or is defective.
