Silent blocks of the front levers on Škoda Yeti - these are consumables that many owners begin to notice only when they have already “died”. But in vain: worn rubber-metal joints not only worsen handling, but also gradually destroy the seats in the levers, which ultimately costs many times more. The problem is especially pressing for cars with a mileage of over 100,000 km or those who often drive on broken roads.
In this article, we’ll look at how to independently diagnose a faulty silent block, what signs indicate an imminent replacement, and what to do if you hear a characteristic knocking sound in the front suspension. And also - detailed replacement instructions with nuances for Yeti different generations, comparison of original and analog spare parts, and answers to frequently asked questions.
Signs of wear on the silent blocks of the front levers
The first symptoms of “dying” silent blocks are often confused with faulty shock absorbers or ball joints. But there are several specific signs that directly indicate rubber-metal hinges:
- 🔊 Knocking or squeaking when driving over bumps at low speed (especially noticeable on speed bumps). The sound comes from the front, but is not accompanied by vibration on the steering wheel.
- 🚗 Pulling the car to the side when braking or accelerating, worn silent blocks change the wheel alignment angles, even if the wheel alignment is normal.
- 🔄 Uneven tire wear (especially the inner edge) is a signal that the suspension is not working correctly, and the silent blocks no longer fix the lever in the correct position.
- 🛑 "Floating" camber: After changing tires or repairing the suspension, the wheel alignment angles are faster than usual.
On Škoda Yeti (especially pre-facelift versions) there is one peculiarity: knocking can only appear in cold weather or after a long period of parking. This is due to the fact that the rubber insert of the silent block hardens in the cold and loses its elasticity. If the sound disappears after the car warms up, this is almost a 100% sign of wear.
⚠️ Attention: If on your Yeti silent blocks with aluminum bushings (instead of steel), their service life is reduced by 30–40%. Such parts are often supplied in non-original kits - check the markings before purchasing!
- Every 10,000 km
- Only when knocking occurs
- Once a year before maintenance
- Never checked
What silent blocks are on the Škoda Yeti: original vs analogues
On Škoda Yeti (depending on the year of manufacture and type of suspension) two types of silent blocks are installed:
- 🔧 Front control arms — two silent blocks for each lever (upper and lower). Original article:
5Q0 407 181 A(left) and5Q0 407 182 A(right). - 🔧 Rear arms (on a multi-link suspension) - here the silent blocks are larger and fail less often. Article:
5Q0 501 515.
Original parts from VW Group They last an average of 100–120 thousand km, but their price is steep: a set for both levers will cost 8–12 thousand rubles. An alternative is analogues from trusted brands:
| Brand | Article | Price per set (2 pcs.) | Features |
|---|---|---|---|
| Lemförder | 33445 01 |
3 500–4 200 ₽ | The quality is close to the original, but the rubber compound is softer - suitable for cold climates. |
| TRW | JTC1342 |
4 000–4 800 ₽ | Reinforced bushings, but may creak the first 500 km after installation. |
| Febi | 22610 |
2 800–3 300 ₽ | A budget option, but the resource is 20–30% lower than the original. |
| SASIC | 2005015 |
2 500–3 000 ₽ | Suitable for a temporary replacement, but often becomes dull in the cold. |
On Yeti 2013–2017 model years (facelift) the silent blocks of the front control arms have an increased diameter of the inner bushing (22 mm instead of 20 mm in the pre-facelift model). Specify this parameter when purchasing, otherwise the part simply will not fit into place!
Diagnostics: how to check silent blocks without a lift
For an accurate diagnosis, you need a lift or inspection hole, but a preliminary check can be done in a garage. You will need:
- 🔦 Flashlight (preferably with a magnetic mount).
- 👁️ A pry bar or long screwdriver.
- 🚗 Jack and stops (if there is no hole).
Step by step instructions:
- Jack up the car and remove the wheel. Chock the rear wheels!
- Inspect the silent block for cracks, rubber breaks or play. The original rubber should be elastic, without “squeezed out” areas.
- Take a tire iron and try move the lever up and down regarding the subframe. If there is play, the silent block is worn out.
- Check alignment of mounting bolts: if the lever is displaced relative to the body, this is a sign of “tired” hinges.

If you have access to a viewing hole, pay attention to condition of seats in the lever. Often a worn silent block “breaks” the socket, and the new hinge no longer fits tightly. In this case, you will have to change the lever assembly.
⚠️ Attention: On Yeti with engines1.8 TSIand2.0 TDIBefore replacing silent blocks, be sure to check the condition subframe supports. Their wear accelerates the destruction of silent blocks by 2–3 times!
Do-it-yourself step-by-step replacement of front control arm silent blocks
Replacing silent blocks with Škoda Yeti refers to work of medium complexity. If you have experience in suspension repairs, you can do it in 3-4 hours. For beginners, it is better to enlist the help of a partner, especially at the stage of pressing in new parts.
Tools and materials:
- 🔧 Set of sockets and keys (required)
16 mm,18 mm,21 mm). - 🔨 Puller for silent blocks (or a homemade device made from a bolt, nut and pipe).
- 🛠️ WD-40 or similar penetrating lubricant.
- 🔥 Gas burner (optional, for stuck bolts).
- 📏 Vernier calipers (to check the pressing depth).
Work order:
- Remove the wheel and disconnect the brake caliper (hang it on a wire so as not to damage the hose).
- Unscrew the nut securing the ball joint to the lever (you will need a key for
21 mm). - Press out the ball pin from the lever using a puller. If it is not there, carefully hit it with a hammer through the wooden spacer.
- Unscrew the bolts securing the lever to the subframe (usually
16 mmand18 mm). Here you may need WD-40 or a torch - the bolts often stick. - Remove the lever and clamp it in a vice. Press out the old silent blocks with a puller or knock them out through a mandrel.
- Press in new silent blocks, making sure they sit down flush with the edge of the lever. Use the old parts as a guide.
- Reassemble everything in reverse order, not forgetting to tighten the bolts with the required torque (see table below).
| Bolt/nut | Tightening torque (Nm) | Note |
|---|---|---|
| Attaching the arm to the subframe (front bolt) | 100 ± 10 | Tighten on a loaded suspension (vehicle on wheels). |
| Attaching the lever to the subframe (rear bolt) | 80 ± 5 | Lubricate threads before installation. |
| Ball joint nut | 50 ± 5 | Check after 100 km. |
If the new silent block does not want to sit in the socket, cool it in the freezer for 1-2 hours, and slightly heat the lever with a hair dryer. This will make pressing easier.
Common replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes, which later become costly. Here are the most common:
- 🔧 Incorrect pressing: if the silent block is installed crookedly or not completely, it will quickly collapse. Check alignment using a caliper.
- 🔨 Using a hammer without a mandrel - this leads to deformation of the rubber insert and reduces the life of the part.
- 🚗 Tightening bolts on suspended suspension: all lever fastenings must be tightened only under load (car on wheels).
- 🛑 Ignoring Seats: if the socket in the lever is broken, the new silent block will not last long. In this case, you need to either restore the seat (bore and insert a repair sleeve), or change the lever assembly.
Another typical problem is retightening of bolts. On Yeti The tightening torque of the lever fastenings is critical: if you exceed the norm, the silent block will deform; if you don’t tighten it enough, there will be play. Use a torque wrench!
What should I do if there is still a knocking noise after replacement?
If the knocking noise persists, check:
1. **Condition of the subframe supports** - they can transmit vibrations to the body.
2. **Play in the ball joint** - sometimes its wear is disguised as “symptoms” of silent blocks.
3. **Tightening the bolts** - especially the rear mounting of the lever (it often loosens after the first 100 km).
4. **Condition of the wheel bearing** - its hum at speed can be confused with the knock of the suspension.
Should I change the silent blocks myself or go to a service center?
It's up to you to decide, but here are the arguments for and against self-replacement:
Advantages of self-replacement:
- ✅ Saving 3-5 thousand rubles (cost of work in the service).
- ✅ Quality control: you know exactly which parts are installed and how they are pressed.
- ✅ Experience that will be useful for future repairs.
Cons:
- ❌ There is a risk of damaging the lever when pressing it out (especially if there is no puller).
- ❌ You will need a special tool (torque wrench, puller).
- ❌ Without a pit or lift, the process will take 2 times longer.
If you have never repaired a suspension, it is better to contact a service center. But if you have experience replacing ball or shock absorbers, with silent blocks on Yeti you can handle it. The main thing is to take your time and follow the instructions.
On Škoda Yeti with all-wheel drive (4×4), replacing the silent blocks of the front control arms requires additional checking of the wheel alignment angles. After repairs, be sure to do a wheel alignment!
FAQ: Frequently asked questions about silent blocks on the Škoda Yeti
How long do silent blocks on Yeti last in Russian conditions?
On average - 80–100 thousand km. But if the car often drives on dirt roads or is used for wear and tear in winter (sharp starts, braking), the service life is reduced to 50–60 thousand km. The quality of the rubber compound also affects durability: original parts last longer than analogues.
Is it possible to drive with worn silent blocks?
Technically yes, but it's dangerous. Worn joints impair handling, especially at high speeds or during sharp maneuvers. In addition, they accelerate the wear of tires and other suspension elements (balls, shock absorbers). If the silent block is completely broken, the lever may rotate, which will lead to loss of control over the car.
Is it necessary to do a wheel alignment after replacement?
Definitely! Even if you replaced the silent blocks without removing the lever, the wheel alignment angles will change. On Yeti with a multi-link suspension, wheel alignment is done after any intervention in the front suspension. The cost of the service is about 1,500–2,000 rubles.
What is the difference between silent blocks for Yeti with gasoline and diesel engines?
Structurally - nothing. But on diesel versions (especially with a motor 2.0 TDI) the suspension experiences heavy loads due to the weight of the engine. Therefore, silent blocks here wear out 15–20% faster. For such machines it is better to choose reinforced analogues (for example, TRW or Lemförder).
Is it possible to restore the seat in the lever if it is broken?
Yes, but this is a temporary solution. Masters use two methods:
- Boring the socket and inserting repair sleeve (suitable diameter).
- Weld the damaged area and drill a new hole (requires Xia lathe).
Both options will extend the life of the lever by 30–50 thousand km, but it is safer to change the assembled part.
