Silent blocks of the front levers on ŠKODA Octavia A7 (2013–2020) is one of those components that wear out “silently,” but in critical condition turns a comfortable ride into a nightmare. Knocks on bumps, vibrations in the steering wheel, uneven tire wear - all this can signal the need for replacement. Unlike the rear silent blocks, the front ones experience enormous loads: they dampen vibrations from the engine, gearbox and road shocks, while simultaneously ensuring the exact position of the wheel.
Owners Octavia A7 We are often faced with a dilemma: should we replace the silent blocks separately or the lever assembly? Original spare parts from VW Group are expensive, but the market offers dozens of analogues - from budget Febi up to bonus Lemförder. In this article, we will look at how to diagnose a malfunction, which part numbers are suitable for different engines (1.4 TSI, 1.6 MPI, 2.0 TDI), and why replacing silent blocks without removing the lever is a dangerous undertaking. We will also provide current prices for 2026 and show you how to save up to 40% on repairs without losing quality.
Signs of wear on silent blocks: when to go for diagnostics
Silent blocks on Octavia A7 designed for 80–120 thousand km, but the actual period depends on the driving style and the quality of the roads. The first symptoms of wear are often confused with problems with shock absorbers or ball joints. Here are the key signs that it's time to check your front control arms:
- 🚗 Knock from front when driving over speed bumps or potholes, it is especially clearly audible at low speeds.
- 🌀 Vibration on the steering wheel when accelerating or braking, which disappears after 60–70 km/h.
- 🔄 Uneven tire wear (usually the inner edge) - silent blocks affect wheel alignment.
- 🔧 Play in the leverwhich is felt when rocking the wheel with your hands (checked on a lift).
Wear of silent blocks on machines with engines 1.8 TSI and 2.0 TDI — due to high torque, deformed bushings can lead to displacement of the lever and damage to the wheel bearing. If you ignore the problem, the consequences will cost 3-5 times more than timely replacement.
⚠️ Attention: On Octavia A7 with all-wheel drive (4x4), the wear of the silent blocks of the front levers is accelerated by 20–30% due to the additional load from the driveshaft. Check them every 60 thousand km!
- Once every 10 thousand km
- Only when knocking occurs
- Before the seasonal tire change
- Never checked
Original articles and analogues: what to choose for replacement
On ŠKODA Octavia A7 Two types of front levers are installed depending on the engine and configuration:
- For models with gasoline engines (1.4 TSI, 1.6 MPI, 1.8 TSI) - lever with article number
5Q0 407 151(left) and5Q0 407 152(right). - For diesel engines 1.6 TDI and 2.0 TDI - reinforced levers
5Q0 407 151 Cand5Q0 407 152 C(they differ in the material of silent blocks).
Original silent blocks from VW will cost 3,500–4,800 rub. per piece, but many car owners choose analogues. The table below shows proven brands with prices for 2026:
| Brand | Article | Price (for 1 piece), rub. | Features |
|---|---|---|---|
| Lemförder | 35114 01 / 35115 01 | 2 800–3 200 | OEM supplier for VW Group, resource 100+ thousand km |
| Febi | 35114 / 35115 | 1 800–2 100 | Budget option, softer than the original |
| TRW | JTC1342 / JTC1343 | 2 500–2 900 | Reinforced bushings, suitable for harsh conditions |
| Sasic | 2005141 / 2005142 | 1 500–1 700 | Low resource (50–60 thousand km), only for temporary replacement |
Important: On the Octavia A7 with adaptive suspension (DCC), levers with modified silent blocks are installed (articles ending with the letter D). Using standard analogues will lead to errors in the system!
When purchasing silent blocks, check for the presence of metal bushings - on cheap fakes they are often replaced with plastic, which reduces the service life by 2-3 times.
Step-by-step replacement of silent blocks: tools and nuances
Replacing silent blocks with Octavia A7 requires removal of the front arm because pressing out on site without a special puller is impossible (risk of damage to the seat). To work you will need:
- 🔧 Silent block remover (for example, Hazet 897-2 or equivalent).
- 🔨 16, 18 and 21 mm sockets (for lever and stabilizer link bolts).
- 🔩 Torque wrench (lever bolt tightening torque - 80 Nm + 90°).
- 🛠️ WD-40 or liquid wrench (bolts often stick).
Replacement algorithm:
- Raise the car on a lift or jack and remove the wheel.
- Unscrew the bolt securing the lever to the subframe (you will need an extension and a lever to secure it).
- Remove the stabilizer link and ball joint bolt.
- Press out the old silent blocks with a puller and clean the seat from corrosion.
- Install new bushings, lubricating them with soapy water (do not use oils!).
- Reassemble the assembly in reverse order, observing the tightening torques.
Stock up on new lever mounting bolts (disposable!)
Check the condition of the ball joint and stabilizer link

At official dealer stations ŠKODA they charge for replacing silent blocks 8,000–12,000 rub. (including wheel alignment). Self-repair will cost 2-3 times less, but requires experience - errors during pressing will lead to play and repeated replacement.
⚠️ Attention: After replacing the silent blocks with Octavia A7 Be sure to do a wheel alignment! Even a minimal shift of the lever by 1–2 mm disrupts the suspension geometry, which leads to “eating” the tires over 5–10 thousand km.
Is it worth changing the entire lever assembly or just the silent blocks?
This question causes heated debate on forums. Arguments for replacing the lever assembly:
- ⚙️ Compatibility Guaranteed — the new silent blocks fit perfectly to the lever.
- ⏳ Save time - no need to bother with pressing out.
- 🔧 Resource — the original lever will last longer than individual bushings.
Arguments for replacing only silent blocks:
- 💰 Price — the lever assembly is standing 12,000–18,000 rub., and a pair of silent blocks is 3-4 times cheaper.
- 🔄 Environmental friendliness — no need to dispose of a working lever.
- 🛠️ Flexibility - you can choose reinforced analogues (for example, TRW or Lemförder).
Experts recommend change the lever assembly in three cases:
- The lever is deformed or cracked.
- The seats of the silent blocks are broken (play more than 0.5 mm).
- The vehicle is used in difficult conditions (taxi, off-road).
What happens if you install non-original silent blocks?
Cheap analogues (for example, Sasic or Optimal) often have soft rubber that “floats” when heated. This leads to:
- Increased lever play after 20–30 thousand km.
- Loss of control accuracy (the car “floats” at speed).
- Accelerated wear of the ball joint due to changed geometry.
Common replacement mistakes and how to avoid them
Even experienced craftsmen make mistakes that shorten the service life of silent blocks. Here are the most common:
- Using a hammer to press in - this deforms the bushing and seat. Hydraulic or screw puller only!
- Tightening bolts by weight — the lever must be loaded (the car is on wheels or supported with a jack under the hub).
- Ignoring Corrosion - Rust on the bolts or lever leads to uneven tightening.
- Savings on breakdown — after replacement, the suspension geometry always changes.
Another typical problem is mixed up left and right levers. On Octavia A7 they are visually similar, but have different shapes of seats for silent blocks. Refer to the markings:
- Left lever - article number ends with
...151. - Right lever - article number ends with
...152.
1) Tightening torque of the lever bolt (should be 80 Nm + 90°).
2) Condition of the subframe (cracks or corrosion).
3) Play in the ball joint or stabilizer link.-->
How much does a replacement cost in 2026: prices and where is it cheaper?
The cost of work and spare parts varies depending on the region and type of service station. Below are the average prices for Octavia A7 (Muscovites can add 15–20%):
| Service/Spare part | Price, rub. | Notes |
|---|---|---|
| Replacing silent blocks (2 pcs.) | 4 000–6 000 | Without taking into account wheel alignment |
| Replacement of lever assembly (1 pc.) | 3 500–5 000 | + cost of the part (RUB 12,000–18,000) |
| Original silent block (VW) | 3 500–4 800 | Articles: 5Q0 407 309 (left), 5Q0 407 310 (right) |
| Wheel alignment (front axle) | 1 500–2 500 | Definitely after replacement! |
Where is the cheapest place to replace:
- 🔧 Garage workshops — 3,000–4,500 rub. for the work, but there is a risk of running into low-quality parts.
- 🏢 Service station network (for example, “Vilgud” or “Fit-Service”) — 5,000–7,000 rubles, but with a 1-year warranty.
- 🏭 Official dealer — 10,000–14,000 rubles, but they use original spare parts.
Lifehack: If you buy spare parts yourself, ask for a discount on the work - many service stations reduce the price by 10-15% in this case.
How to extend the life of silent blocks: prevention and advice
Resource of silent blocks for Octavia A7 depends not only on the quality of the parts, but also on the driving style. Here's what will help delay replacement:
- 🛣️ Avoid sudden starts and braking — dynamic loads destroy the rubber of the bushings.
- 🚧 Avoid potholes and speed bumps at a speed not exceeding 20 km/h.
- 🔧 Check the play in the suspension every 15 thousand km (just pump the wheel with your hands).
- 🌡️ Monitor the temperature — overheating (for example, when towing) accelerates the aging of rubber.
Also note rubber quality in silent blocks:
- 🔴 Red or yellow tires (for example, at Febi) - soft, dampens vibrations well, but wears out faster.
- 🟢 Black rubber (y Lemförder or TRW) - tougher, but lasts longer.
⚠️ Attention: After washing the suspension in winter, be sure to treat the lever bolts with an anticorrosive agent (for example, Molykote). Salt and reagents cause corrosion, which causes bolts to break when unscrewed!
If you notice that the silent blocks on the Octavia A7 have “leaked” (the rubber has cracked and is coming out of the bushing), do not delay replacement - this is the last stage before the destruction of the metal holder.
FAQ: Answers to frequently asked questions
Is it possible to drive with knocking silent blocks?
Short-term (1-2 weeks) - yes, but you risk getting:
- 🔄 Wheel alignment violation and “eaten” tires.
- 🛠️ Broken ball joint or wheel bearing.
- 🚗 Poor handling at high speeds.
If there is severe wear, the lever may rotate in the subframe seat - this will lead to an emergency.
Which brand of silent blocks is the most reliable for Octavia A7?
Based on test results and owner reviews:
- Lemförder — best price/quality ratio (lifetime 90–110 thousand km).
- TRW — optimal for difficult conditions (taxi, off-road).
- VW Original - if you need 100% compatibility, but the price is high.
Avoid Sasic, Optimal and no-name - their resource rarely exceeds 30–40 thousand km.
Do I need to replace silent blocks in pairs?
Definitely! Even if it knocks only on one side, the second silent block is already worn out by 60–70%. Replacement with a pair provides:
- 🔧 Uniform distribution of suspension loads.
- 🚗 Predictable car behavior in corners.
- 💰 Savings on wheel alignment (you won’t have to do it twice).
Is it possible to replace silent blocks without removing the lever?
Technically possible, but highly not recommended. Reasons:
- ⚠️ Risk of damage to the seat in the lever.
- 🔧 It is impossible to properly clean corrosion.
- 🛠️ Pressing out “in place” often leads to misalignment of the bushing.
An exception is the use of a specialized puller Laser 5830, but it is only available at professional service stations.
How often do you need to check the silent blocks on the Octavia A7?
Recommended schedule:
- 🔍 Every 15 thousand km — visual inspection for cracks and play.
- 🛠️ Every 60 thousand km — full suspension diagnostics.
- 🚗 After strong blows (for example, hitting a curb).
On cars older than 5 years or with mileage >100 thousand km, check the silent blocks every 10 thousand km.
