Silent blocks of the front levers on ล KODA Fabia 2 (2007โ2014) is one of the โweakestโ suspension components, which requires attention after 80โ100 thousand km. Their wear is manifested by knocking, the car pulling to the side and uneven tire wear. Car services charge from 6 to 12 thousand rubles for a replacement (depending on the region), but if you have the tools and patience, you can do the work yourself - saving up to 70% of the cost.
In this article we will analyze step by step replacement process, let's look in detail at selection of spare parts (original vs analogues), we will reveal typical mistakesthat beginners admit, and we will give recommendations on resource extension new silent blocks. We will pay special attention unique feature Fabia 2: asymmetry of the levers of the left and right sideswhich is often overlooked.
Signs of wear on silent blocks: when is it time to change them
Silent blocks (or โrubber-metal hingesโ) dampen vibrations and ensure the mobility of the suspension arms. Over time, the rubber loses its elasticity and cracks or peels off from the metal bushing. On Fabia 2 the first symptoms appear after 6โ7 years of operation, even if the mileage is short.
Main symptoms of a malfunction:
- ๐ Knocking or squeaking in the front suspension when driving over uneven surfaces (especially at low speeds).
- ๐ Pulling the car to the side when braking or accelerating, even if the wheel alignment is normal.
- ๐ Uneven tire wear (more often - the inner or outer edge).
- ๐ Vibrations on the steering wheel when driving on a flat road (especially at speeds of 60โ80 km/h).
- ๐ง Visual damage: cracks, rubber breaks or play when swinging the lever with a mount.
If you ignore these symptoms, wear of the silent blocks will lead to lever deformations, damage to ball joints and even wheel bearing camber. On Fabia 2 With 1.2/1.4 TSI engines, play in the rear silent blocks of the front control arms is especially critical - it directly affects the wheel alignment angles.
โ ๏ธ Attention: On cars with mileage of more than 150 thousand km, replacement of silent blocks may require simultaneous replacement of levers โ their seats are often deformed, and new bushings do not fit tightly.
Which silent blocks to choose: original or analogues
Original spare parts from ล KODA/VW for Fabia 2 (body code 5J) have articles:
- ๐น Front silent block of the lever:
6Q0 407 181 A(left) and6Q0 407 182 A(right). - ๐น Rear silent block of the lever:
6Q0 407 183(universal for both sides).
The cost of the original is from 1,200 to 1,800 rubles per piece. However, many owners choose analogues from trusted brands that are not inferior in quality, but are 30โ50% cheaper:
| Brand | Article (front/rear) | Price, rub. | Features |
|---|---|---|---|
| Lemforder | 31306 01 / 31307 01 |
800โ1 100 | High quality rubber, suitable for aggressive driving. |
| Febi | 22720 / 22721 |
600โ900 | Softer than the original, but durable with quiet use. |

Tools and preparation for replacement
To work you will need special tool, without which pressing out and pressing in silent blocks may result in damage to the levers or new parts. Minimum set:
- ๐ง Silent block remover (for example, KUKKO 21-1 or Laser 3202).
- ๐ง Hydraulic press (or vice with adapters for pressing).
- ๐ง Socket heads by 16, 18 and 21 mm (for bolts of levers and stabilizer link).
- ๐ง WD-40 or liquid key - bolts on Fabia 2 often get stuck.
- ๐ง Torque wrench (tightening torque of the lever bolts is 80โ100 Nm).
- ๐ง Hammer and pry bar - for dismantling stuck parts.
Before starting work:
- Place the car on flat area and secure the rear wheels with chocks.
- Loosen the wheel bolts and raise the car on a jack (or lift).
- Remove the wheel and clean the suspension elements from dirt (especially the silent block seats).
- Treat all threaded connections
WD-40and let sit for 10-15 minutes.
โ ๏ธ Attention: On Fabia 2 with 1.6 MPI engines (BSE,BSF) the front suspension has additional bracket for attaching the lever to the subframe. Its bolts often break when unscrewed - prepare spare ones (N 908 132 02).

Step-by-step replacement instructions
The process of replacing silent blocks with Fabia 2 includes dismantling the lever, pressing out old bushings, installing new ones and reassembling. Let's look at each stage in detail.
1. Removing the front arm
Procedure:
- Unscrew bolt securing the arm to the subframe (18 mm head). If it doesn't work, use impact wrench or heat the nut with a gas burner (carefully so as not to damage the rubber elements!).
- Disconnect stabilizer link (16 mm bolt) and ball joint (21 mm head).
- Move the lever out of its seat and remove it. On Fabia 2 left and right levers not interchangeable โ do not confuse them when reinstalling!
2. Pressing out old silent blocks
Use a puller or press:
- Install the lever on the press rubber part up.
- Carefully push out the old bushing while holding the lever. If the silent block is โstuckโ, first cut it with a hacksaw.
- Clean the seat from rust and rubber residues.
For the rear silent block (smaller size) you may need adapter for the puller. Do not try to knock out the bushings with a hammer - this will deform the lever!
3. Installation of new silent blocks
Key points:
- Before pressing, lubricate the seat soap solution (do not use oils - they destroy the rubber!).
- Make sure the silent block is installed strictly according to the marks (original parts have arrows or inscriptions
TOP). - Press the bushing in until it stops, avoiding distortions. If a puller is used, tighten the bolt smoothly without jerking.
After installation, check that the rubber does not have folds or gaps between the bushing and the lever. If they are, the silent block is defective or installed crookedly.
4. Assembly and tightening
When reinstalling the lever:
- Tighten the bolts only under load โ put the car on the wheels and rock it so that the suspension takes the working position.
- Tightening torque:
- Bolt securing the arm to the subframe:
100 Nm. - Ball joint bolt:
80 Nm. - Stabilizer link bolt:
50 Nm.
- Bolt securing the arm to the subframe:
If after replacement there is squeaking sound when turning the steering wheel, lubricate the rubber parts of the silent blocks silicone grease (not lithol!). This will eliminate friction and extend the life of the parts.
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing silent blocks with Fabia 2. Here are the most common:
- Ignoring lever asymmetry. The left and right sides have different geometries - if they are mixed up, the wheel alignment angles will be impossible to adjust.
- Incomplete pressing. If the silent block does not reach the stop, it will quickly fail. Check the clearance between the lever and the bushing after installation.
- Reusing old bolts. On Fabia 2 arm mounting bolts disposable - they break when tightened again.
- Tightening without load. If the bolts are tightened by weight, the silent blocks will work at the wrong angle, which will lead to their rapid wear.
- Saving on puller. Attempts to knock out bushings with a hammer often end in cracks in the lever.
One more critical error - do not check status subframe. On cars with a mileage of more than 150 thousand km, the seats under the levers are deformed, and even new silent blocks do not fit smoothly. In this case it is required subframe repair (editing or replacing bushings).
What to do if the silent block does not press in?
If the new bushing does not fit into the seat, the reasons may be the following:
1. Lever deformation โ check its geometry with a ruler. If the bend is more than 1 mm, the lever must be replaced.
2. Silent block defect โ compare the diameter of the bushing with the original. Tolerance: ยฑ0.1 mm.
3. Dirt or rust โ clean the seat with a metal brush and lubricate it with soapy water.
If all else fails, use file for accurate fitting of the seat (no more than 0.2 mm in diameter).
Service life and how to extend the resource
Resource of silent blocks for ล KODA Fabia 2 depends on several factors:
- ๐ Riding style: with aggressive driving (sharp starts, braking), tires wear out 2-3 times faster.
- ๐ก๏ธ Climatic conditions: in regions with frequent temperature changes (from -30ยฐC to +30ยฐC), rubber loses its elasticity within 3โ4 years.
- ๐ฃ๏ธ Road quality: Constant driving through potholes and washboards reduces the service life to 40โ50 thousand km.
- โ๏ธ Quality of parts: original silent blocks last 100-120 thousand km, analogues - 50-80 thousand km.
To extend the life of new silent blocks:
- ๐ง Check regularly (every 10 thousand km) play in suspension and the condition of the rubber elements.
- ๐ฟ Wash the pendant contactless car wash in winter - salt and reagents destroy rubber.
- ๐ ๏ธ Lubricate silent blocks every 20 thousand km silicone grease (not lithol!).
- ๐ Follow toe angles โ incorrect geometry accelerates wear.
On Fabia 2 with 1.2 TSI engines (CBZ, CZDA) it is especially important to monitor the condition of the rear silent blocks of the front control arms - they experience increased loads due to the greater weight of the power unit.
- Original: 100โ120 thousand km (5โ7 years).
- Premium analogues (Lemforder, TRW): 80โ100 thousand km.
- Budget analogues: 40โ60 thousand km.
When replacing, always install new bolts and check the geometry of the levers!-->
Cost of work in the service vs independent replacement
Prices for replacing silent blocks of front control arms ล KODA Fabia 2 vary depending on region and service level:
| Service type | Cost of work (per side), rub. | Cost with spare parts (original), rub. | Lead Time |
|---|---|---|---|
| Official dealer | 4 000โ6 000 | 10 000โ14 000 | 3โ4 hours |
| Independent service | 2 500โ4 000 | 7 000โ10 000 | 2โ3 hours |
| Garage craftsmen | 1 500โ2 500 | 5 000โ8 000 | 4โ5 hours |
| On your own | 0 (with tool present) | 3 000โ6 000 | 5โ8 hours |
The savings when replacing yourself are obvious, but keep in mind hidden costs:
- ๐ง Purchase of a puller and press (from 3,000 rubles, if not in stock).
- ๐ Possible replacement of bolts and nuts (another ~1,000 rubles).
- โฑ๏ธ Time - without experience, the work will take a whole day.
If you have never repaired a suspension, it is better to contact a service center. Errors when replacing silent blocks with Fabia 2 often cost more than the savings - for example, a deformed lever or incorrectly set camber angles will require additional expenses.
Frequently asked questions (FAQ)
Is it possible to drive with worn silent blocks?
Short-term (1-2 weeks) - yes, but this will lead to:
- Accelerated tire wear (up to 30% faster).
- Damage to ball joints and wheel bearings.
- Deterioration in handling, especially at high speeds.
If the rubber on the silent blocks is crumbled or the bushing is loose, it needs to be replaced immediately.
Do I need to do a wheel alignment after replacement?
Definitely! Even if you carefully installed the levers in their original places, the wheel alignment angles will change due to:
- Wear of subframe seats.
- Deformation of levers during pressing.
- Changes in suspension height (if the silent blocks were heavily worn).
The cost of adjusting the wheel alignment: 1,500โ2,500 rubles.
Is it possible to replace only the front or only the rear silent block?
Technically yes, but not recommended. On Fabia 2 The front and rear silent blocks wear out approximately equally. If you replace only one, the second one will soon fail and you will have to repeat the job. The exception is if the rear silent block is still in perfect condition (checked visually and for play).
How to check silent blocks without removing the lever?
Inspect them through an inspection hole or on a lift:
- Rock the lever with a pry bar - play of more than 1-2 mm is unacceptable.
- Check the rubber for cracks, tears, or separation from the metal.
- Please note bushing position โ if it is shifted relative to the lever, the silent block requires replacement.
Also pay attention to traces of oil โ if the rubber is saturated with technical fluids, its elasticity is impaired.
Which silent blocks are better - rubber or polyurethane?
On Fabia 2 original rubber ones are recommended or analogues from Lemforder/TRW. Polyurethane (for example, Powerflex) have their pros and cons:
Pros:
- Service life is 2โ3 times longer.
- Better handling (less โimpressivenessโ).
Cons:
- Greater rigidity - transmits vibrations to the body.
- 2โ4 times more expensive (from 2,500 rubles per piece).
- They require precise installation - the slightest misalignment leads to squeaks.
Polyurethane silent blocks are justified only for sports driving or cars with lowered suspension.
