Car Škoda Octavia Tour It is a legendary model that continues to occupy a confident position in the market due to its maintainability and simplicity of design. However, even reliable suspension over time requires attention, especially in conditions of Russian roads, where the quality of the coating leaves much to be desired. One of the most common problems in the front suspension of this model is wear and tear. support bearing a depreciation rack that connects the body with the rack mechanism.
Ignoring the malfunction can lead to serious consequences: from deterioration of handling and the appearance of backlashes to failure of the entire shock rack or collapse of the hub bearing. Replacing the support bearing - the procedure is not the most complicated, but requires accuracy and the presence of a special tool. Owners. Octavia Tour It is important to understand how to recognize the problem in time and what kind of problem it is. pole-piece It is better to choose for long service.
Many motorists confuse knocks in the front suspension, taking them for a malfunction of the transverse stability stabilizer or levers. In fact, the characteristic creak when turning the steering wheel in place or a deaf knock when passing irregularities often indicates precisely the destruction of the wheel. thrust bearing Stands. Proper diagnosis will save you money and time, preventing unnecessary spending on parts that could last for a long time.
Design features of the support on the Octavia Tour
On first generation cars Octavia Tour (A4, body 1U) uses a classic McPherson type front suspension scheme. In this design, the bearing supports a critical function: it allows the shock rack to rotate along with the bearing. swivel fist when you turn the steering wheel. Without this node, turns would be impossible, since the rack is rigidly fixed in the body.
The design of the node is a complex mechanism consisting of an external body, an inner ring and a separator with a ball-piece. The inner ring is rigidly connected to the shock absorber rod, and the outer one is attached to the body through three bolts. Between these elements is the rubber-pillowIt extinguishes vibrations and noises transmitted from the road to the body of the car.
Particular attention should be paid to the material from which the bearing is made. In factory configurations, products from poor-quality steel or rubber are often used, which quickly smacks in the cold. That's why. support-life on Octavia Tour It often does not exceed 60-80 thousand kilometers of mileage, especially if the car is operated in harsh climatic conditions.
The main symptoms of malfunction and methods of diagnosis
To understand that the bearing failed, you can by a number of characteristic signs that appear in the process of operation. The most striking symptom is a deaf knock in the area of the front wheels when passing even small irregularities or lying policemen. This sound is caused by the fact that ball mechanism The metal parts start to beat each other without damping.
The second sure sign is creaking or grinding when the steering wheel is rotating, especially when the car is standing still or moving at low speed. If you hear that sound, it means rubber-clip The bearing has lost elasticity or collapsed, and friction occurs over the dry metal. In some cases, the knock may disappear when moving in a straight line, but return when cornering.
Diagnosis of malfunction can be carried out independently, but for an accurate result it is recommended to use a lift or observation pit. Ask the assistant to sway the steering wheel left-right, and at this time, place your hand on the top of the shock absorber. If you feel a beating or backlash in the place of attachment of the support to the body, then bearing cannot be repaired.
- Deaf knocking when passing irregularities at low speed.
- Screaking the steering wheel when turning on the spot or on the move.
- Visual backlash at the top of the shock absorber during the rocking.
- Deterioration of handling and "vatality" of the steering wheel on turns.
⚠️ Note: If you notice backlash in the support, do not postpone repairs. A broken bearing can jam, which will lead to the impossibility of turning the wheel or, in the worst case, to the separation of the rack from the body during a sharp maneuver.
Selection of quality spare parts: brands and analogues
The auto parts market is full of offers, and choose a reliable one support bearing it can be difficult. For Škoda Octavia Tour There are both original parts and high-quality analogues from leading world manufacturers. The original (VAG) is often expensive and sometimes sold at all with the top cup, which increases the cost of repairs.
The best alternative to the original are brands specializing in suspension elements. SKF, SNR and Lemförder They produce products that are not inferior in quality, and sometimes exceed factory parts. These companies use stronger steels and improved rubber compositions, which significantly extends the life of the unit. High quality bearing It must remain elastic even at temperatures below -30°C.
Avoid cheap analogues from unknown brands, especially from markets or dubious online stores. Such details often have a backlash after the first thousand kilometers of run. Rubber cushion in cheap products cracks quickly, which leads to dirt and moisture entering the mechanism, causing corrosion and accelerated wear. Choosing a quality brand is the key to ensuring that you will not return to this problem in the next 5 years.
When choosing, you should also pay attention to the configuration. Some manufacturers offer pole-pieceThis includes not only the bearing, but also the top cup, and sometimes even the anther and damper. This simplifies assembly and ensures that all node elements are compatible.

⚠️ Note: When buying a support in the assembly, make sure that the new nut of the shock absorber rod is included in the kit. The old nut can not be used, since it has a self-contrary thread, which after unscrewing loses its properties.
Tools and preparation for replacement
Before starting the work, all the necessary tools must be prepared. Replacement support bearing requires the use of a special tool to compress the spring of the shock absorber, since the spring is under high pressure. Attempting to disassemble the rack without a compressor can lead to injuries or breakage of parts.
You will need the keys on 13, 17, 18, as well as the head on 21 to unscrew the shock absorber rod nut. It is necessary to have a dynamometer key for tightening the bolts of attaching the support to the body with the correct force. It will be necessary to remove the rack wheel wrench And a jack, and a ball-top detacher, if you're going to shoot the whole rack.
Also, don’t forget about penetrating lubricant (such as WD-40), if the bolts are boiling. It is best to work on a lift or in a viewing pit to have free access to the top of the underwing and support mounts. Spring puller It is a critical tool that cannot be replaced by improvised methods, such as wire screeds.
- Set of end heads and keys (13, 17, 18, 21 mm).
- Special detacher for compressing the shock absorber springs.
- Torque wrench for tightening bolts.
- The sleeves are made of sleeves (for ease of removal).
- Penetrating lubricant and brush to clean the thread.
☑️ Preparing for replacement
Step-by-step instructions for replacing a support bearing
The replacement process begins with the dismantling of the wheel and unscrewing the nut of the shock absorber rod. If the nut doesn't unscrew, use a special hexagon key that often comes complete with a spring removable. Caution: After unscrewing the nut, the spring is under tremendous stress, so do not let the filmmakers go abruptly.
Next, you need to unscrew three bolts of the support attachment to the car body. They are in the under-hood space, under the plastic protection of the arch. Then disconnect the rack from the swivel fist by unscrewing the two bolts from the bottom. Now the rack is completely free and it can be removed from the car for further work on the workbench.
On the workbench, install a rack in the spring removable and gently squeeze them until the pressure on the upper support disappears. Then you can unscrew the nut of the rod and disassemble the knot. Replace. old bearing on the new one, making sure that the rubber cushion sits tightly and has no cracks. The assembly is done in reverse order.
It is important to observe the correct sequence of tightening of bolts. First tighten the bolts of the support attachment to the body, then the bolts of the mounting of the rack to the rotary fist. Only after that you can release the springs and install a rack on the car. Tightening torque The bolts of the support mounting are usually 20 Nm + 90 degrees, but it is better to clarify this in the technical documentation.
What to do if the rod nut turns?
If the hexagon does not hold the rod, you can use a special tool with a hexagon inside or pinch the rod in the vise through a wooden gasket so as not to damage the thread.
Replacement of the bearing requires mandatory compression of the spring with a special tool; the use of improvised means is unacceptable due to the risk of injury and breakdown of parts.
Diagnosis after repair and nuances of operation
After completion of the work, it is necessary to check the correctness of the installation. Scroll the steering wheel several times left and right to make sure there are no creaks and jamming. Also check if there is a knock when the body is swaying. Installation quality It can only be appreciated after a short trip on rough roads.
Don’t forget to go through the process of dissolution. Even a slight displacement of the rack during installation can change the angles of the wheels, which will lead to uneven wear of the tires and deterioration of handling. In service on Octavia Tour This procedure takes no more than 30 minutes and is inexpensive.
During operation, pay attention to the state of anther shock absorber. If it is torn, dirt and water can get inside, which will accelerate the wear not only of the bearing, but also of the shock absorber rod. Regular inspection of the suspension will allow you to identify problems in time and avoid expensive repairs in the future.
Before starting work on replacing supports, be sure to disconnect the negative terminal of the battery to avoid accidental short circuit when working with electrical wiring in the underhood space.
Frequently asked questions from Octavia Tour owners
Owners of this model often face similar questions regarding the repair and maintenance of the suspension. Below are the answers to the most common of them, based on many years of experience in operation.
Can you change the bearing without changing the support?
Technically, this is possible if the support body and rubber cushion are in perfect condition. However, in practice, rubber elements eventually tan and crack, so the masters recommend changing the assembly or at least the bearing with a new cushion to ensure reliability.
Do I need to change the bearings in a pair or can I use one at a time?
It is highly recommended to change them with a couple. Even if only one knocks, the second is at the same age and operating conditions. Replacing one by one can lead to the fact that after a month you will have to disassemble the suspension again, which will increase the total cost of repairs.
How often should the condition of the bearings be checked?
It is recommended to check their condition with each oil change or once every 20-30 thousand kilometers of mileage. When the first signs of knocking or creaking appear, the diagnosis should be carried out immediately to avoid destruction of the node.
Does the quality of the roads affect the life of the bearing?
Yes, the quality of roads is one of the main factors. The pits, track and poor coating create impact loads that quickly destroy ball elements and rubber clip. On bad roads, the service life can be halved.
Is it possible to drive with a faulty support bearing?
You can drive, but it is not recommended. This is dangerous for safety, as the broken bearing can jam, which will lead to loss of handling. In addition, vibrations are transmitted to the body, causing fatigue of the metal and the destruction of other elements of the suspension.
Regular maintenance and timely replacement support bearings - the guarantee of safe and comfortable driving on your Škoda Octavia Tour. Do not skimp on the quality of spare parts and trust the work to professionals if you are not confident in your abilities. A properly selected part will last a long time and give you confidence at the wheel.
