Replacement of the front hub on the ŠKODA Octavia A5: instructions from A to Z

Front hub on ŠKODA Octavia A5 - a critically important node, on which not only smoothness of the course depends, but also safety of management. Wear of the bearing or deformation of the hub itself is manifested by a characteristic hum at speed, vibration of the steering wheel or uneven wear of the tires. If you notice these symptoms, you can not pull with repair: the destruction of the bearing on the go can lead to a jamming of the wheel and an emergency.

In car service stations, the hub replacement is charged from 3,000 to 6,000 rubles (depending on the region and the complexity of the work), but with the tool and minimal skills, this operation can be performed independently. In this article, we will discuss in detail the process of replacing the front hub with the Octavia A5 (including versions with engines 1.6 MPI, 1.8 TSI and 2.0 TDIWe will point out the typical errors and give recommendations on the choice of spare parts. Particular attention will be paid to the nuances that are often missed even by experienced masters - for example, the correct tightening of the hub nut and checking the beat after installation.

Signs of front hub malfunction on Octavia A5

The first symptoms of wear of the hub bearing or the hub itself on ŠKODA Octavia A5 are often ignored because they develop gradually. However, there are a number clear signalswhich indicate the need for diagnosis:

• 🔊 Hum or howl from the wheel, which increases when accelerating. At an early stage, noise may disappear when turning the steering wheel left / right (this is due to the redistribution of the load on the bearing).
• 🌀 Steering wheel vibration or body at a speed above 60-80 km / h. Often mistaken for wheel imbalance, but after balancing the problem remains.
• 🔄 Wheel play when rocking it in a vertical plane (checked on a jack). Even the smallest gap is a reason for replacement.
• 🚗 Uneven tire wearEspecially if it is on the same wheel. This may be due to the beating of the hub or distortion of the brake disc.

On Octavia A5 with a run of more than 150,000 km, a fault of the hub is often accompanied by a fault hyperheating on the problem side. This is because the worn bearing creates additional resistance to rotation. You can check this by touching the drive after the trip (caution – it can be hot!). The temperature of the faulty side will be noticeably higher.

⚠️ Attention: If the hum suddenly stops when driving at speeds above 100 km/h, this may mean that the bearing is already collapsed And the wheel is about to jam. In this case, you must immediately stop and evacuate the car.

Which hub to choose for replacement: original vs analogues

On ŠKODA Octavia A5 There are two types of hubs, depending on the year of release and configuration:

• 🔧 For 2004-2008 models. (before facelift) - hub with art. 1K0 407 611 (left) and 1K0 407 612 (right).
• 🔧 For models 2009-2013. (after facelift) - art. 1K0 407 611 A and 1K0 407 612 A. The difference is in the design of the seat under the ABS sensor.

Original hubs from VW Group (production SKF or FAG) cost between 4,500 and 6 000 rubles per piece. However, there are worthy analogues on the market that are not inferior in quality, but cheaper by 30-50%:

Brand	Article	Price, rub.	Features
SKF	VKBA 3533	3 800–4 200	One of the best analogues, bearing with increased resource
FAG	713 6106 30	4 000–4 500	Original supplier for VW- High reliability.
SNR	R155.50	3 200–3 600	Budget option, suitable for a quiet ride
Febi	22710	3 500–3 900	Good price/quality ratio, often complete with nuts

When choosing a hub, pay attention to complete set: some sets do not have a locking ring or a nut. Also check if the hub is suitable for your brake system: Octavia A5 with engines 2.0 TDI (140 hp) and 1.8 TSI brake discs of larger diameter are installed (312 mm), which requires a hub with a suitable seating position.

Hub replacement tools and materials

For self-replacement of the front hub on Octavia A5 you will need the following set of tools:

• 🔧 Jack and stand (It is not recommended to work only on the jack!)
• 🔧 Balloon wrench to remove the wheel.
• 🔧 Socket heads 13, 16, 17, 19 mm and extension cord.
• 🔧 Ratchet wrench Or a lever collar.
• 🔧 Wheel bearing puller (can be rented).
• 🔧 Torque wrench (It is necessary to properly tighten the nut of the hub!)
• 🔧 Hammer and metal drift (for careful removal of the hub).
• 🔧 WD-40 or similar penetrating lubricant.
• 🔧 New hub nut (Reuse is not acceptable, and reuse is not acceptable!)

Also prepare wire brush to clean the seats and bearing grease (for example, Molykote BR2 Plus or LIQUI MOLY LM 50). If you are planning to replace the hub for the first time, we recommend you to purchase it. shrus It is easily damaged when removing the drive shaft.

Step-by-step instructions for replacing the front hub

The process of replacing the hub ŠKODA Octavia A5 It takes 2 to 4 hours depending on the experience and condition of the fasteners. Below is the following: step by step instructions taking into account all the nuances:

Step 1. Preparing the car

Place the car on a level surface, engage first gear (or P for automatic transmission) and place chocks under the rear wheels. Loosen the hub nut on a stationary car (The moment of puffing is very high - up to 250 N·m, so it will be difficult to turn it on weight). Use a 30mm head and a lever at least 50cm long.

Step 2. Removal of the wheel and brakes

Lift the car with a jack, remove the wheel and unscrew two bolts of the brake caliper mount (head 13 mm). Hang the caliper on the wire to the spring so as not to damage the brake hose. Then remove the brake disc - it can sit tightly, so gently tap it with a hammer through a wooden pad.

Step 3. Disconnection of the SRUS and the ABS sensor

Unscrew the bolt of the ball support attachment to the lever (head to 16 mm) and remove the finger from the bicillary. Next, unscrew the three bolts of the hub attachment to the shock rack (head 13 mm). If you Octavia A5 installed ABS sensor, disconnect its connector and remove the sensor from the bracket on the hub.

Step 4. Removing the old hub

Now you need to press the hub with the bearing. For this:

1. Remove the locking ring from the back of the hub (use round-triggers).
2. Set the detachable and evenly press the hub. If there is no filmmaker, you can gently knock it down with a hammer, but this is risky - you can damage the seat on the counter.
3. After removing the hub, clean the landing place of dirt and rust with a metal brush.

Step 5. Installation of a new hub

Before installing a new hub, apply a thin layer of lubricant to the landing surface. Set the hub in place and press it with a removable or gently hammer through a wooden spacer. Puff nuts hub must be made only on the car standing on wheels, with a moment of 250 N·m! This is critical for the proper operation of the bearing.

Step 6. Assembly and testing

Install the brake disc, caliper and wheel. Lower the car to the ground and Tighten the hub nut with a dynamometer key. After that, check the back of the wheels and the absence of beating. For this:

• Raise the wheel on the jack and rock it in vertical and horizontal planes - there should be no backlash.
• Scroll the wheel with your hand: it should rotate smoothly, without jamming and extraneous noises.

⚠️ Attention: If after the replacement of the hub there was vibration at a speed above 80 km / h, this may indicate a significant increase in the speed of the humidity. cockpit or skew. In this case, it is necessary to repeat the procedure, since ignoring the problem will lead to a rapid failure of the bearing.

Common mistakes when replacing a hub and how to avoid them

Even experienced car owners make mistakes when replacing the hub with a new one. Octavia A5Which leads to re-repair or serious breakdowns. Here are the most common of them:

• 🔧 Using an old hub nut. This nut is disposableBecause when it is stained, it is deformed. Reuse leads to spontaneous unwinding and the risk of wheel loss.
• 🔧 Pulling the nut on the suspended wheel. The bearing must be loaded with the weight of the car, otherwise the moment of tightening will be incorrect, which will lead to its overheating.
• 🔧 Ignoring the beat test. If the hub is mounted with a skew, this will cause vibration and uneven wear of the tire.
• 🔧 Lack of lubrication on landing surfaces. This complicates pressing and can lead to microcracks in the metal.
• 🔧 ABS sensor damage when you take the hub off. Always disconnect the connector before dismantling!

Another common mistake is hub-selection. For example, on Octavia A5 with engine 2.0 TDI (170 hp) Hubs with reinforced bearings are installed (art. 1K0 407 611 B) which are not interchangeable with standard ones. Installation of the "wrong" hub will lead to its rapid failure.

What to do if the hub does not press in?

If the new hub does not sit in place, check:

1. The cleanliness of the seat (whether there are burrs or rust).

2. The coaxiality of the holes under the bolts of attachment to the rack.

3. The absence of deformation of the hub itself (marriage happens even in original spare parts).

If the problem remains, try to cool the hub in the freezer for 1-2 hours - the metal will shrink and pressing will be easier.

When to contact the service: difficult cases

Although the front hub replacement Octavia A5 It is considered an operation of medium complexity, there are situations when it is better to trust professionals:

• 🔧 If during dismantling ball-support bolt broke or the thread in the rack has been damaged.. To restore, welding equipment or cutting new threads will be required.
• 🔧 If after replacement humming or vibrationAll the steps are done correctly. This may indicate a malfunction of the SRUS or wear of the silent blocks of levers.
• 🔧 If the car has air suspension (optional for versions Octavia A5 Scout). Special equipment is required to relieve pressure in the system.
• 🔧 If the hub is removed The SRUS anther is damaged.You are not sure if you are replacing it correctly. An unsealed anther will lead to dirt entering the hinge and its failure.

It is also worth considering that on Octavia A5 with the system ESP after replacing the hub it may be necessary resetting ABS errors using a diagnostic scanner (for example, VCDS or Launch X431). If the ABS lamp continues to burn after assembly, it could mean damage to the sensor or its wiring.

Hub service life and fault prevention

Front hub resource for ŠKODA Octavia A5 depends on operating conditions and quality of spare parts:

• 🔄 Original hubs (VW/SKF/FAG) serve 120,000–150,000 km with a calm driving style.
• 🔄 High-quality analogues (SKF, FAG, Febi) — 80,000–100,000 km.
• 🔄 Budget analogues (SNR, Optimal) — 50,000–70,000 km.

To extend the life of your hub, follow these recommendations:

• 🚗 Avoid sudden starts and braking - this creates shock loads on the bearing.
• 🚗 Check regularly wheel play (every 20,000 km).
• 🚗 Follow condition of the CV joint boots — their damage leads to dirt getting into the hub assembly.
• 🚗 When washing a car do not direct the water jet on the wheel bearing - this can wash out the grease.
• 🚗 Use quality lubricants when replacing (for example, Molykote or LIQUI MOLY).

If you often drive off-road or in highly dusty conditions, the life of the hub is reduced by 30–40%. In this case, it is recommended to check its condition every 50,000 km and, if necessary, carry out preventive replacement.

FAQ: Frequently asked questions about replacing the hub on an Octavia A5

Is it possible to drive with a hum in the hub?

No, this is extremely dangerous. The hum indicates wear of the bearing, which can collapse at any moment, which will lead to the wheel jamming. Driving at high speed is especially risky - if the bearing fails, the wheel can lock and the car becomes uncontrollable.

Does the hub assembly need to be replaced or can just the bearing be replaced?

On Octavia A5 The hub and bearing are a non-separable unit. Theoretically, it is possible to press out the old bearing and press in a new one, but this requires special equipment and does not guarantee reliability. In addition, the hub itself wears out over time, so it is more advisable to replace the entire assembly.

What is the torque for the hub nut?

For ŠKODA Octavia A5 The tightening torque for the hub nut is 250 Nm. Tightening must be done only with the car standing on its wheels, otherwise the bearing will work with distortion. After tightening, the nut must be locked by bending its edge into the groove on the shaft.

What to do if vibration appears after replacing the hub?

Vibration can be caused by several reasons:

1. Incorrect tightening of the nut (too loose or too tight).
2. Distortion of the hub during pressing.
3. Damage to the brake disc (if it was removed and reinstalled at an angle).
4. Wheel imbalance (even if the balancing was normal before the replacement, it should be repeated).

It is necessary to re-check the tightening of the nut, the wheel play and, if necessary, contact a service center for diagnostics.

Is it possible to replace the hub without removing the brake caliper?

Technically this is possible, but extremely inconvenient. The brake caliper interferes with access to the hub mounting bolts, and the risk of damaging the brake hose increases significantly. In addition, without removing the disk, it is difficult to assess the condition of the hub and correctly press in a new one. We still recommend removing the caliper and disc - this will take an extra 10-15 minutes, but will save time and nerves overall.
