Suspension system Skoda Octavia Tour is one of the most reliable in its class, but even it is subject to natural wear and tear during active use. A key element that provides a smooth ride and precise control is the front shock absorber mount, which often fails before the struts themselves. Ignoring the first symptoms of a breakdown can lead to accelerated destruction of other suspension components and reduced safety on the road.
Owners of used cars often encounter a characteristic knocking sound on bumps or a squeaking sound when turning the steering wheel. These sounds most often indicate that support bearing or the rubber-metal part of the support has exhausted its service life. In this article, we will look in detail at how to diagnose the problem yourself, which spare parts to choose, and how to properly replace it without contacting a service center.
Functional purpose and structure of the node
Shock absorber support in Skoda Octavia Tour performs several critical tasks at once, connecting the car body with the suspension. It serves as the attachment point for the shock absorber strut to the body, transferring vertical loads from the road to the frame. Without a proper support, the entire impact force when driving through potholes or speed bumps would be transferred directly to the metal body, causing destructive vibrations.
Structurally, the unit consists of three main parts: an upper bearing that allows the stand to rotate with the steering wheel, a rubber damping pad and a metal mounting cup. Rubber-metal support dampens high-frequency vibrations that the shock absorber itself is unable to absorb. If the rubber dries out or cracks, the suspension geometry is disrupted, which leads to uneven tire wear and poor handling.
It is important to understand that the bearing and support are often sold as a single unit, but in some cases they can be replaced separately. For Octavia Tour with 1.6 MPI or 1.8 TSI engines, the most common design is where the bearing is pressed into the upper cup. When replacing, it is recommended to replace the entire set, since separation of units often leads to rapid repeated failure of adjacent elements.
Main symptoms of malfunction and diagnostic methods
You can determine that it is time to change the support by a number of characteristic symptoms that become noticeable even to an inexperienced driver. The first and most reliable sign is a dull metallic knock in the area of โโthe front wheels when driving over uneven surfaces, especially at low speeds. This sound occurs because the shock absorber begins to hit a broken mount without having the proper damping pad.
The second warning sign is a squeaking or grinding sound when turning the steering wheel at a standstill or at low speed. This sound indicates jamming or destruction upper support bearing. If the bearing does not rotate freely, the steering wheel may have difficulty returning to center, and a distinct crunching sound can be heard during sharp turns. It is also worth paying attention to the appearance of creaks coming from the suspension when driving over speed bumps.
The third symptom is visual damage or disruption to the geometry of the rack. When inspecting the engine compartment, you can see cracks on the rubber part of the support, traces of corrosion on the metal cup, or traces of oil on the shock absorber spring. If you notice that support cup has shifted relative to the body, this is a critical sign that requires immediate replacement of the part to prevent the strut from coming off.
โ ๏ธ Attention: Do not confuse the knocking sound of the support with the knocking of the anti-roll bar. If the knocking noise is heard when the car is rocked by hand, and not just when driving over uneven surfaces, the problem is most likely in the stabilizer struts, and not in the shock absorber support.
For accurate diagnosis, you can use the rocking method. Raise the front wheel with a jack and, holding the top and bottom of the wheel, try to rock it. If there is play, which is accompanied by a knock coming precisely from the upper mounting point, then the support is to blame. It is also useful to check the condition of the shock absorber boot, since often the destruction of the support is accompanied by damage to the protective cover.
- Deaf banging on the bumps
- Creaking sound when turning the steering wheel
- Visual tire wear
- Difficulty returning the steering wheel to center
Selection of suitable spare parts and market analysis
When choosing a new support for Skoda Octavia Tour A dilemma arises: to buy an original kit or a high-quality analogue. Original from the manufacturer VAG (Volkswagen Audi Group) guarantees perfect geometry and durability of materials, but its cost is often overpriced. The original part number may vary depending on the year of manufacture and suspension type, so be sure to check the vehicle's VIN before purchasing.
Among the proven analogues, brands are in the lead SWAG, Febi Bilstein and Lemfรถrder. These manufacturers often supply spare parts to the assembly line, so their quality is practically the same as the original, and the price is significantly lower. Also popular are products from Sachs and Kyb, which specialize in shock-absorbing systems. It is important to avoid buying cheap spare parts from China or no-name brands, as their rubber quickly hardens and cracks.
The table below shows popular articles and their characteristics for different modifications Octavia Tour (1U2):

Please note that sometimes the delivery kit does not include mounting bolts or nuts, so it is recommended to immediately purchase new fasteners. Old bolts can corrode and break when removed, making replacement more difficult. Fasteners They must be made of high-strength steel and have a protective coating.
Preparation of tools and workplace
Before starting work, it is necessary to prepare a spacious space and a set of tools, since the replacement procedure requires access to the upper part of the suspension from the engine compartment and the bottom of the car. You will need keys and heads on the 13, 15, 17, and a special spring remover if you plan to disassemble the rack completely. For work under the car, you must use it. props or a reliable lift to avoid the risk of falling.
Also, do not forget about penetrating lubricant type WD-40 or similar, which should be treated all threaded connections before unscrewing. This is especially true for the bolts of the mounting of the rack to the rotary fist, which are often clinging to dirt and reagents. Prepare a container for draining possible residues of technical liquids and a rag for cleaning parts.
โ ๏ธ Attention: Work with the depreciation rack is associated with a high risk of injury due to a compressed spring. Never attempt to unclose a spring without a special detacher, as this can cause it to fly out and cause serious damage.
โ๏ธ Preparing to replace the support
Step-by-step instructions for replacing the shock absorber mount
The replacement process begins with the weakening of the shock absorber rod nut. To do this, remove the plastic cap in the hood space and keep the rod from turning with a hexagon or a special key. Rod nut It is switched to 13 or 15, depending on the modification. If you do not plan to change the rack itself, then the nut can simply be loosened, without twisting to the end.
Then the entire rack must be removed. Unscrew the two bolts of the rack mount to the swivel fist from the bottom and disconnect the ABS sensor if it is in the design. Carefully lower the rack down, disconnecting it from the body. At this stage, it is important to maintain the rack so that it does not fall and damage other suspension units or body elements.
After removing the rack on the workbench, use the spring remover to compress it. Press the spring until it stops pressing on the support cup. Now you can unscrew the nut of the rod to the end and remove the old support along with the bearing. Set a new support, making sure that the marks on the spring and the new part match. It is critical for the right job. suspension geometry.
What if the bolt is stuck?
If the bolt does not unscrew, do not use excessive force so as not to break the thread. Use heat with a burner, penetrating lubricant and a percussion instrument. In extreme cases, it may be necessary to drill the bolt, which will greatly complicate the work.
Collect the rack in reverse order, tightening the nut of the rod with the recommended moment. Set the rack in place, fasten it to the swivel fist and fix it in the back. Donโt forget to tighten all the bolts with the desired force using a dynamometer key. After installation, check that the rack is flat and has no distortions.
Proper installation of marks on the spring and the new support guarantees the preservation of the factory geometry of the suspension and the absence of additional loads on the bearing.
Checking the collapse-convergence and final recommendations
After the shock absorber supports have been replaced by Skoda Octavia Tour It is necessary to perform the procedure of disintegration-convergence. Any intervention in the suspension associated with the dismantling of the racks violates the angles of the wheels. Ignoring this step will lead to accelerated wear of rubber, drifting of the car on turns and increase fuel consumption.
After the work is completed, conduct a test trip, paying attention to the absence of extraneous noise and smoothness of the course. The steering wheel should stand evenly, and when rotating there should be no creaks or jamming. If you notice any deviations, return to the service to recheck and adjust the settings.
Regularly checking the condition of the suspension will help you avoid costly repairs in the future. Timely replacement of the shock absorber support is not only comfort, but also your safety on the road. Suspension condition It directly affects the braking distance and stability of the car in emergency situations.
When replacing a support, always change it in pair on both sides of the car, even if one of them looks whole. This will ensure the uniform operation of the suspension and prevent distortions.
Frequently asked questions and answers (FAQ)
How long does it take to replace one shock absorber support?
If you have the necessary tool and experience, replacing one rack takes from 1 to 1.5 hours. If you change both supports at the same time, the process can take about 2.5 hours, including preparation and inspection time.
Can you replace only the rubber part of the support, leaving the bearing?
Technically, this is possible, but not recommended. The bearing and the support work in a bundle, and wear of one element inevitably leads to wear of the other. Replacing the entire unit guarantees the longevity of the repair.
Should I change the spring when replacing the support?
If the spring has no traces of corrosion, cracks or drawdown, it can be left. However, if the spring is old and weakened, it is strongly recommended to replace it with the support to restore the ground clearance and stiffness of the suspension.
What is the point of tightening the nut of the shock absorber rod?
Usually, the puffing moment is from 40 to 60 Nm, but the exact value is always indicated in the technical documentation of the car. Use a dynamometer key for precise tightening.
Does the replacement of the support affect the operation of the airbag?
There is no direct effect, but when dismantling the rack, you need to be careful not to damage the wiring and connectors located next to the security elements. Be careful when working in the under-hood space.
Concluding the review, it is worth noting that Skoda Octavia Tour A car that forgives many mistakes but requires attention to the details of the suspension. Timely replacement of the support of the shock absorber prevents the destruction of the glass bodyThis is the most expensive repair in this situation. Regular inspection and prevention will help your car to serve faithfully for years to come, providing comfort and safety.
