Rear hub on Škoda Fabia 2 (2007-2014, bodywork 5J and 6J) is a critical node on which not only ride comfort but also safety depends. Bearing wear or hub deformation is manifested by hum, vibration at speed and uneven wear of tires. Unlike the front axle, where the hub is integrated with the rotating fist, the rear design is simpler, but has its own nuances: there are often problems with the rear. bearing-place and corrosion of the wheel mounting thread.

In this article, we will analyze how to independently diagnose a malfunction, choose an original or analog hub (with articles and prices), and replace it without a specialized tool. We'll put a special emphasis on Common errors in replacement, which lead to premature failure of the node – for example, incorrect tightening of the nut or ignoring the check of the brake disc. If you hear the characteristic hum at speed 60–80 km/hThe problem, which is amplified when turning the steering wheel, is most likely the problem in the rear hub.

Signs of a bad rear hub Fabia 2

The first signal about problems with the hub is extraneous noiseBut they may be masked by tire wear or transmission problems. To accurately identify the malfunction, pay attention to the following symptoms:

  • 🔊 Hum or howl from the rear wheel, which is strengthened when accelerating to 60-90 km / h and can disappear on turns (due to redistribution of load).
  • 🌀 Vibration on the steering wheel or bodyEspecially noticeable when braking is a sign of the beating of the hub or deformation of the brake disc.
  • 🔧 Wheel play when checking “with the car hanging” (if you grab the wheel at the 9 and 3 o’clock positions and rock it).
  • 🚗 Uneven rear tire wearEven with the correct collapse-convergence - indicates a violation of the geometry of the hub.

It is important to distinguish hub-wear from problems with Stabilizer sticks or cardan. For example, knocking when passing irregularities is more often associated with racks, and a constant hum is 90% of the bearing. For accurate diagnosis, lift the car on the jack and scroll the wheel manually: if you hear a crunch or grinding, and rotation occurs with effort - the hub requires replacement.

⚠️ Attention: On Fabia 2 With ABS, the speed sensor is integrated into the hub. If the dashboard lights up. ERROR ABSThis may be due to damage to the sensor or its wiring during wear of the bearing.

Original articles and analogues of the rear hub

On Škoda Fabia 2 There were two types of hubs, depending on the year of production and configuration:

  • 🔄 Hub without ABS sensor (before 2010, basic versions) - original article 6Q0 501 207.
  • 📡 ABS sensor hub (after 2010, all versions with ABS) - original article 6Q0 501 207A or 6Q0 501 207B (depending on supplier).

The cost of the original hub is from VW Group — from 8,000 to 12,000 rubles. However, there are proven analogues that are not inferior in quality:

Brand Article Price, rubles Notes
SKF VKB 3650 5 500–7 000 The best analogue in terms of price / quality, bearing with increased resource.
Febi 23650 4 800–6 200 Good option for budget repairs, but the resource is lower than that of SKF.
TRW JBS1044 6 500–8 000 Original supplier for VW GroupHigh quality bearing.
Mapco 64100 3 500–4 500 Budget option, but more often there are fakes.

Critical nuance: Fabia 2 with 1.2 TSI and 1.6 MPI engines (after 2012) installed hubs with a modified seat under the ABS sensor. When buying an analogue, check the compatibility with the VIN code!

Rear hub replacement tools

To replace the hub with Fabia 2 No special equipment is required, but there are several mandatory instruments, which you can’t do without:

  • 🔧 30 mm end key (To unscrew the nut of the hub - requires a long lever or tube amplifier).
  • 🔨 Wheel bearing puller (You can rent it, it costs ~500 rubles/day).
  • 🔩 Torque wrench (for tightening the nut with a moment of 120-140 N·m).
  • 🛠️ WD-40 or similar - The nut carvings often get crummy.
  • 🔥 Gas burner (Optionally, if the bearing is "stuck" to the trench).

If you plan to change the hub yourself, prepare in advance. wheel chocks and door-jack — Fabia 2 has a low clearance, and a standard jack may not fit. We also recommend that you have at hand. new hub nut (article N 908 132 02) as the old one deforms when unscrewed.

Step-by-step instructions for replacing the rear hub

The replacement process takes 2-3 hours if the tool is available. Follow the algorithm to avoid errors:

  1. Removing the wheel and brake disc

    Lift the car on the jack, remove the wheel and unscrew the two bolts of the brake caliper mount (key 13 mm). Hang the caliper on the wire so as not to damage the hose. Then remove the brake disc - it can "stick" to the hub, so pre-treat the joint. WD-40 And gently knock the disc down with a hammer through a wooden pad.

  2. Unscrewing the hub nut

    This is the hardest part. The nut is tightened with a moment of 120-140 Nm and often clings. Use a long lever (pipe) and a key of 30 mm. If the nut fails, heat it with a burner (do not point the flame at the anther!). In no case do not try to unscrew the nut while the car is on wheels - this will lead to deformation of the bearing!

  3. Removing the hub

    After unscrewing the nut, remove the hub from the sapf. If it sits tightly, use a removable or gently knock it down with a hammer through a soft spacer. Pay attention to this. bearing-place If there are bullies or corrosion, the claw will have to be restored (surfed).

  4. Installing a new hub

    Before installation, clean the heron of dirt and apply a thin layer copper grease to the seat. Install a new hub, twist the nut and tighten it with a dynamometer key with a moment. 120 Nm. Then, put the slack on the back (if it is designed).

⚠️ Attention: After replacing the hub, be sure to check brake disc runout If it exceeds 0.15 mm, the disc requires a leak or replacement. Otherwise, the vibration will remain when braking.
💡

If the nuts of the hub are unscrewed, do not try to drill it - use a special extractor for nuts (costs ~300 rubles). It'll save you time and nerves.

Typical replacement mistakes and how to avoid them

Even experienced craftsmen make mistakes that reduce the resource of a new hub. Here are the most common:

  • 🔧 Nut-tightening - leads to the destruction of the bearing or backlash of the wheel. Always use a dynamometer key!
  • 🚫 Ignoring brake disc inspection If the disc is deformed, it will create an additional load on the hub.
  • 🔥 Heating the bearing with a burner It destroys the lubrication and seals. You can only heat a nut or a herpf, but not the bearing itself.
  • 🛠️ Using an old nut - it deforms when unscrewed and does not provide reliable fixation.

Another common problem is ABS sensor incompatibility. On Fabia 2 After 2012, hubs with a modified sensor connector were installed. If you bought an analog without taking into account this nuance, ABS will work incorrectly or even refuse. Always check the articles by VIN code or catalog ETKA.

What happens if you don’t replace the squirrel in time?

If the bearing is critically worn, it may jam on the move, which will lead to a wheel lock and loss of control. In addition, the destruction of the bearing separator leads to damage to the brake disc and caliper, which increases the cost of repair 2-3 times.

When to contact the service?

Replace the back hub with Fabia 2 You can do it yourself, but in some cases it is better to trust professionals:

  • 🔧 If you don't have torque wrench Incorrect tightening of the nut will lead to re-repair.
  • 🔥 If the hub nut is I'm so full of it., which does not unscrew even with heating - in the service use special extractors.
  • 📡 If after replacement ABS light bulb on - diagnostics of the sensor and wiring are required.
  • 🚗 If you notice steering wheel beating after replacement - possibly damaged claw or unbalanced wheel.

The average cost of replacing the hub in the service is from 2,500 to 4,000 rubles (excluding spare parts). If you are not confident in your abilities, it is better to pay for the work than risk security. This is especially true for versions of c. ABS and ESPwhere improper installation of the sensor can lead to failures in the stabilization system.

💡

The most common reason for repeated hum after replacing the hub is low-quality or snag. Always check the moment of puffing and buy bearings of proven brands (see below).SKF, TRW).

FAQ: Frequently asked questions about the rear hub Škoda Fabia 2

Is it possible to drive with a humming hub?

In the short term, yes, but it is not worth the risk. With severe wear, the bearing can jam, which will lead to a wheel lock at speed. The maximum mileage with a hum is 500-1000 km, but it is better to replace the hub immediately.

How to check the hub without a lift?

Lift the car on the jack, grab the wheel in the positions "12 and 6 hours" and rock it. If there is a backlash, the hub is faulty. Also scroll the wheel: resistance or crunch indicates wear on the bearing.

Do I need to replace the hub assembly or just the bearing?

On Fabia 2 The bearing is pressed into the hub and is not sold separately. Theoretically, it can be pressed out and replaced, but this is labor-intensive and unreliable - the new bearing may last less due to wear of the seat.

How long does the rear hub last?

The service life of the original hub is 150,000–200,000 km. Analogues (SKF, TRW) serve 100,000–150,000 km. The service life depends on operating conditions: frequent trips on bad roads reduce the resource by 30–40%.

Why did vibration remain after replacing the hub?

The reasons may be the following:

  • The wheel is not balanced.
  • The brake disc is damaged (needs re-grooving).
  • The hub nut is not tightened correctly.
  • The axle is deformed (needs to be checked on a bench).
