Replacing the hub with Skoda Octavia A7 This is a task that every car owner will face sooner or later. The hub bearing and the hub itself wear out due to constant loads, especially if the car is operated on bad roads or with an aggressive driving style. In this article, we will analyze how to determine the fault, what tools and parts will be needed, and also describe in detail the replacement process - from dismantling to installing a new part.
It is important to understand that hub Octavia A7 (including restyled versions 2017โ2020) It has its own design features. For example, different types of hubs are used on the front and rear axles, and bearings can be both removable and integrated into the body. If you have never done such work, it is better to assess your strength in advance or contact the service. However, with minimal experience and the right tools, you can perform the replacement yourself, saving up to 8-12 thousand rubles.
Signs of malfunction of the hub or bearing
The first symptoms of wear of the hub bearing or the hub itself on Octavia A7 They are often ignored, leading to more serious breakdowns. The main signs that should be paid attention to:
- ๐ Hum or howl from the side of the wheel, which increases when accelerating. In the early stages, noise can only appear at speeds above 60-80 km / h.
- ๐ Vibration on the steering wheel Or the body, especially when cornering. This is due to backlash in the bearing or deformation of the hub.
- ๐ Uneven tire wear. If one of the wheels "leads" to the side, this may indicate problems with the hub or collapse-development.
- ๐ Crunching or clicking noise when braking or passing irregularities - a sign of critical wear of the bearing.
On Octavia A7 mileage of more than 100,000. Km, hub bearings often fail due to moisture or dirt through damaged anthers. If you ignore these symptoms, the bearing may jam, which will lead to locking the wheel on the move is one of the most dangerous malfunctions, fraught with accident.
โ ๏ธ Attention: If the wheel is rotated in suspended state (on the jack) crunch is heard or backlash is felt, operation of the car is prohibited! The bearing can break down at any time.
To diagnose, lift the car with a jack and rock the wheel in horizontal and vertical planes. Luft more than 0.5 mm is a reason for urgent replacement. Also check the hub temperature after the trip: if it is hot, it is a sign of friction worn bearing.
- Every maintenance (every 15 thousand km)
- Only when there is noise
- Never checked
- Once a year, on their own.
What are the hubs installed on the Skoda Octavia A7
On Skoda Octavia A7 (including versions with engines 1.4 TSI, 1.8 TSI, 2.0 TDI etc.) different types of hubs are fitted according to the axle and configuration. Here are the main options:
| Position | Article number (OEM) | Manufacturer | Notes |
|---|---|---|---|
| Front hub (left/right) | 5Q0 407 611 A/B |
SKF, FAG, SNR | Suitable for models 2013-2020. systemless 4Motion |
| Front hub (4Motion) | 5Q0 407 611 C/D |
SKF, NTN | For all-wheel drive versions, differs by a reinforced bearing |
| Rear hub | 5Q0 501 503/504 |
FAG, INA | Bearing integrated, sold in the assembly with a hub |
| ABS sensor hub | 5Q0 407 611 E |
Bosch, Hella | Requires careful replacement to avoid sensor damage |
When choosing a spare part, pay attention to bearing quality. Cheap analogues (for example, from Febi or Topran) often serve no more than 30-50,000. km, while original or premium brands (SKF, FAG) sustain 100,000+ thousand. km. Also check if the hub is assembled with a bearing or requires a separate pressing.
For Octavia A7 with the system ESP and ABS It is important to maintain the sensors. If the hub is sold without a sensor, it will have to be rearranged from the old part. In some cases, it may be necessary adapting the ABS sensors via a diagnostic scanner (for example, VCDS or ODIS).
How to distinguish a fake from the original hub?
Original hubs for Skoda have laser engraved articles and logo of the manufacturer (for example, SKF or FAG). Counterfeiting is often characterized by rough metalworking, lack of protective caps on the bearing and lighter weight. Also check the packaging: the original should be dense, with a hologram or protective stickers.
Required tools and materials
To replace the hub with Octavia A7 You will need a specialized tool. Without it, the risk of damage to parts or failure to cope with the task increases significantly. Here's the full list:
- ๐ง Jack and stops (be sure to insure your car!). For Octavia A7 A jack with a carrying capacity of at least 2 tons is suitable.
- ๐ฉ Socket heads 17, 19, 21 mm (for hub bolts and lever attachment). Better to use the percussion heads.
- ๐จ Hammer and drift from a soft metal (for the breaking of the hub). The alternative is a detachable bearing.
- ๐ง Torque wrench (for tightening the hub bolt with a moment of 90-110 Nยทm).
- ๐ ๏ธ Vise and press (If the sleeves are separated).
- ๐งฒ Magnet or telescopic grip (to remove the lock rings).
- ๐งด Bearing grease (for example, Molykote BR2 Plus) and WD-40 for unscrewing stuck bolts.
If you plan to press the bearing separately, you will additionally need:
- ๐ Bearing mandrel (The diameter must be the same as the seat).
- ๐ฅ Gas burner or hair dryer (To heat the hub before pressing).
โ ๏ธ Attention: On Octavia A7 with the system 4Motion Replacing the back hub may require removal of the semi-axis. Without experience, this operation is better to entrust to professionals - improper installation will lead to oil leakage from the gearbox.
Also prepare new hub-mounting bolts (article N 910 807 01) are disposable and must be replaced with each dismantling. The use of old bolts is fraught with their break when moving.
โ๏ธ Preparing to replace the hub
Step-by-step instructions for replacing the front hub
Front hub replacement process Skoda Octavia A7 It takes about 2-3 hours if you have experience. If you are doing this for the first time, be patient and follow the instructions:
Step 1. Dismounting of wheel and brake gear
Lift the car with a jack and remove the wheel. Then unscrew the two bolts of the brake caliper mount (17 mm head) and hang it on the wire so as not to damage the hose. Remove the brake disc - it can sit tightly, so gently tap it with a hammer through a wooden pad.
Step 2. Untwisting the mortar nut
This is the most critical moment. The nut of the hub is tightened with great force (about 200 Nยทm), therefore:
- Have an assistant press the brake pedal to lock the hub.
- Use a 30mm impact head and a long collar.
- If the nut does not budge, process it WD-40 and wait 10โ15 minutes.
Step 3. Hub removal
After unscrewing the nut, remove the locking ring (if any) and knock the hub with a hammer through the mandrel. Be careful - do not damage the slats on the drive shaft! If the hub sits too tightly, use a removable.
Step 4: Install the new hub
Before installation, clean the seat of dirt and apply a thin layer of lubricant to the shaft slits. The new hub should sit without distortion. Tighten the nut with a dynamometer key with the moment 90โ110 Nm (Exact values are specified in the repair manual).
Step 5: Assembly and Testing
Install the brake disc, caliper and wheel. After lowering the car, check the absence of backlash and extraneous noise when the wheel is rotating. If everything is in order, make a test run with a gradual acceleration to 60-80 km / h.
If you hear a crunch when you tighten the nut, immediately weaken it! This is a sign that the bearing is crooked or damaged. Repeat the pressing.
Features of replacing the rear hub
Rear hub on Octavia A7 It is more difficult to change due to the integrated bearing and the proximity of the brake mechanisms. The main differences from the front axle:
- ๐ง Brake drum (on versions with drum brakes) is removed after unscrewing the guide pins.
- ๐ฉ Fastening bolts hubs to the heron often stick - use penetrating lubricant and percussion tool.
- ๐ ABS sensor on the rear axle is attached to the hub, so when replacing it you need to carefully rearrange.
- ๐ Half shaft on all-wheel drive versions (4Motion) may interfere with dismantling, sometimes requiring partial displacement.
Work algorithm:
- Remove the wheel and brake drum (or disc if disc brakes are installed).
- Disconnect the ABS sensor connector and remove it from the bracket.
- Unscrew 4 bolts of the hub attachment to the heron (head to 17 mm).
- Remove the locking ring and press the hub with a removable.
- Install a new hub, pre-grease the seat. Tighten the cross-cross bolts with the moment
80โ90 Nm.
โ ๏ธ Attention: On the rear axle Octavia A7 after replacing the hub it may be necessarycalibrationthrough a diagnostic scanner. Without this, the system may generate an error01279(wheel speed sensor malfunction).
If after the replacement there was a creak or grinding during braking, check whether the brake shield has bent or whether dirt has not got between the pads and the disc.
On the rear axle Octavia A7 The hub often "sticks" to the heron due to corrosion. In no case do not try to knock it down with a hammer without a detacher - this will lead to deformation of the seat!
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing a hub with Skoda Octavia A7. Here are the most common ones and ways to prevent them:
- ๐ง Retightening the hub nut - leads to premature bearing wear. Always use a torque wrench!
- ๐งฒ Lost retaining ring - without him, the hub could turn. Check its availability before assembly.
- ๐ฅ Heating a bearing with an open flame - it destroys the lubricant. Use a building hair dryer or oil to heat.
- ๐ Ignoring wheel alignment After replacing the hub, the angles of the wheel installation may change. Adjust it!
- ๐ฉ Reusing old bolts They stretch when tightened and can burst. Always bring new ones.
Another typical problem is Damage to the CV boot When you dismantle the hub. If you notice cracks or ruptures, the anther should be replaced, otherwise dirt will get into the hinge, and it will fail in 5-10 thousand. km.
If after the replacement of the hub there was vibration at a speed above 80 km / h, the reasons may be as follows:
- Incorrect tightening of bolts (check the moment).
- Damage to the brake disc (check the beat indicator).
- Wheel imbalance (balance it on the stand).
What to do if the hub cannot be removed?
If the hub is "stuck" to the shaft, use a removable with a three-paw grip. In extreme cases, you can carefully heat the seat with a hairdryer (not higher than 200 ยฐ C) and try to knock down the hub through a wooden paddle. Do not hit the shaft - it will damage the SRUS!
Cost of work and spare parts in 2026

Save on the quality of spare parts is not worth it. Cheap hubs from Febi or Topran They can only serve 20,000 to 30,000. mile, after which a re-repair will be required. The best option for the ratio of price / quality - brands SKF, FAG or SNR.
FAQ: Frequent questions about replacing the hub with the Octavia A7
Can I drive with a knock in the hub?
Nope! Knocking or backlash in the hub indicates critical wear of the bearing. With further operation, it can jam, which will lead to a locking of the wheel on the go. The risk of an accident in this case is extremely high.
Is it necessary to do a wheel alignment after replacing the hub?
If you have replaced only the hub without dismantling the levers or turning fist, you can not do the collapse-descend. However, if there is a vibration on the steering wheel or the car is taken aside, check the angles of the wheel installation.
What kind of lubricant to treat the bearing when pressed?
Use specialized lubricants for hub bearings, for example, Molykote BR2 Plus, SKF LGMT 2 or FAG Arcanol LOAD120. Regular Litol or Solid oil They are not suitable โ they can not withstand high temperatures.
Is it possible to replace just the bearing and not the entire hub?
Technically yes, but only if the hub is not deformed and the bearing is sold separately (for example, for the front axle). On the back axle. Octavia A7 The bearing is usually integrated into the hub, so it changes only in assembly.
How long does the hub last on the Octavia A7?
The service life depends on the operating conditions. On average, the original hubs are enough for 100-150 thousand. km, analogues - by 60-100 thousand. km. With aggressive driving or frequent off-road trips, the resource is reduced to 50-80,000. km.
