Replacement silent blocks on ŠKODA Octavia Tour - a procedure that sooner or later every owner has to perform. These rubber-to-metal joints are responsible for absorbing vibrations and ensuring correct suspension geometry, but over time they wear out, lose their elasticity and begin to “knock”. If you notice extraneous noise when driving over bumps, deterioration in handling or uneven tire wear - most likely, the problem lies with them.

In this article we will figure out how to replace it yourself front and rear silent blocks on Octavia Tour (including restyled versions A5 FL and A7), what tools will be needed for this, and what to pay attention to to avoid mistakes. You will also find out how much service work costs, which silent blocks are better to choose (original vs analogues), and how to extend their service life. If you have never repaired a suspension, don’t worry: with the right approach, the task is quite feasible even for a beginner.

Signs of wear on silent blocks on a ŠKODA Octavia Tour

Silent blocks do not break suddenly - their wear occurs gradually, and often owners Octavia Tour They attribute the first symptoms to “road features” or seasonal changes. However, these signals cannot be ignored: Worn front arm silent blocks increase the load on wheel bearings by 30% and accelerate wear of ball joints.

The main signs that it’s time to change the silent blocks:

  • 🔊 Knocking or squeaking in the suspension when driving over small irregularities (especially noticeable on speed bumps).
  • 🚗 Pulling the car to the side when driving in a straight line (even after wheel alignment).
  • 🔄 Uneven tire wear — the protectors are “eaten up” from the inside or outside.
  • 🛣️ Vibrations on the steering wheel at speeds above 80 km/h, which are not related to wheel balancing.
  • 🔧 Visible cracks or tears in the rubber on silent blocks (can be seen when inspecting the pit).

On Octavia Tour most often fail front lower control arm silent blocks (especially on cars with mileage of more than 100 thousand km) and rear silent blocks of torque rods. The latter usually “live” longer, but their replacement takes more time due to the need to dismantle the subframe.

⚠️ Attention: If on your Octavia Tour silent blocks with aluminum bushings (for example, from Lemforder or TRW), do not use a hammer to press them in - this will lead to deformation of the metal. Only press or special mandrels!

Which silent blocks to choose: original or analogues?

When replacing silent blocks with ŠKODA Octavia Tour The owner is faced with the question: to buy original spare parts or stop at high-quality analogues. Original silent blocks (see the table below for articles) guarantee 100% compatibility, but their price is often inflated. Analogs from trusted brands (Lemforder, Febi Bilstein, TRW) can last no worse, but cost 30–50% less.

Important nuance: on Octavia Tour after 2013 (facelift A7) silent blocks were installed with improved rubber compound, which tans less in the cold. If you live in a region with cold winters, pay attention to this when choosing an analogue.

Position Original article Analogs (brand + article) Approximate price, rubles
Front lower arm (silent block) 1K0 407 181 C / 1K0 407 182 C Lemforder 30407 01 / TRW JBU743 1 200–2 500
Rear torque rod (silent block) 1K0 505 555 Febi Bilstein 23420 / Sasic 4001810 800–1 800
Front stabilizer (bushing) 1K0 411 315 Sidem 51740 / Moog K90455 400–900
Rear trailing arm (silent block) 1K0 505 557 A Meyle 100 411 0016 / SWAG 30 92 3420 1 500–3 000

If you are planning complete replacement of levers (and not just silent blocks), pay attention to the kits from TRW or Moog — they come with already pressed silent blocks and ball joints, which simplifies installation. However, this option will cost more (from 5,000 rubles per lever).

📊 What silent blocks do you prefer to install on the Octavia Tour?
  • Only original
  • High-quality analogues (Lemforder, TRW)
  • Budget analogues (Febi, Sasic)
  • I don't know, I've never changed it

Tools and preparation for replacing silent blocks

To replace silent blocks with ŠKODA Octavia Tour you will need special tool, without which it is almost impossible to press in new parts. Minimum set:

  • 🔧 Jack and stops (or lift/pit).
  • 🔨 Silent block remover (for example, Kukko 21-1 or similar).
  • 🛠️ Set of sockets and keys (required TORX T30 and T45 for rear arms).
  • 🔩 Torque wrench (to tighten the bolts to the correct torque).
  • 🧲 Magnet or telescopic grip (so as not to lose small parts during dismantling).
  • 🔥 Gas burner or hair dryer (for heating silent blocks during pressing).

If you change rear silent blocks, you will additionally need:

  • 🔧 Ball joint puller (for example, Hazet 4962-1).
  • 🛠️ Mandrels for pressing (can be made from old bearings).
  • 🔩 WD-40 or similar fluid (for unscrewing stuck bolts).

Before starting work necessarily:

  1. Place the machine on a flat surface and secure the wheels with chocks.
  2. Loosen the wheel bolts and jack up the car (or drive it into a pit).
  3. Clean all threaded connections that will need to be unscrewed from dirt and rust.
  4. If you are working with the rear suspension, remove crankcase protection (if there is one).

⚠️ Attention: On Octavia Tour many bolts securing arms and tie rods are disposable (for example, the front lower control arm bolt to the subframe). They must be replaced with new ones during reassembly!

Step-by-step replacement of front silent blocks on Octavia Tour

Front silent blocks on Octavia Tour They are more difficult to change than the rear ones, due to the need to dismantle the levers. Let's look at the process using an example lower front control arm (the most common case).

Step 1. Dismantling the lever

  1. Remove the wheel and unscrew the nut ball joint to the steering knuckle (you will need a key for 18 and puller).
  2. Unscrew the two bolts securing the lever to the subframe (head on 16 or 18). Attention: the bottom bolt often sticks - use WD-40 and an impact wrench.
  3. Carefully move the lever out of the subframe and remove it.

Step 2. Pressing out the old silent block

To do this:

  1. Clamp the lever in a vice (using soft pads to avoid damaging the paint).
  2. Use a puller or mandrel of a suitable diameter to push out the old silent block. If it gets stuck, heat the lever with a hair dryer (do not overheat - the rubber may catch fire!).
  3. Clean the seat from rust and dirt.

Step 3. Installing a new silent block

This is the most critical stage:

  1. Lubricate the seat and outer surface of the new silent block soap solution (do not use oils - they corrode the rubber!).
  2. Carefully press the part using a mandrel, making sure it fits exactly (distortions are unacceptable!).
  3. Check that the silent block has not turned after pressing - if this happens, it needs to be replaced.

Step 4: Reassembly

Place the lever in place, tighten new bolts (tightening torque - 80–100 Nm) and reassemble everything in reverse order. After replacement necessarily do a wheel alignment!

💡

If the new silent block does not want to “fit” into the seat, cool it in the freezer for 1–2 hours - this will make pressing in easier.

Features of replacing rear silent blocks

Rear silent blocks on Octavia Tour change less frequently, but the process is more labor-intensive due to the need for dismantling subframe. Main nuances:

1. Removing the subframe

  • 🔧 Unscrew the bolts securing the subframe to the body (4 pieces, head on 18).
  • 🔩 Disconnect jet thrust and anti-roll bar.
  • 🚗 Lower the subframe on a jack or hang it on a wire (don't let it fall!).

2. Replacing the silent blocks of the reaction rods

The main thing here is not to confuse front and rear traction (they differ in length). The process is similar to the front silent blocks, but requires more care due to the close location of the fuel tank and exhaust system.

3. Assembly and tightening

After installing new silent blocks:

  • Tighten the subframe bolts only under load (the car must be on wheels!).
  • Subframe bolt tightening torque: 60–80 Nm + additional turn on 90°.
  • Check the geometry of the rear suspension - if after replacement the car “drives”, the camber will need to be adjusted.
What happens if you don’t replace the rear silent blocks on time?

Ignoring the wear of the rear silent blocks on Octavia Tour leads to:

- Accelerated tire wear (rubber wears out in a herringbone pattern).

- Play in the suspensionwhich may cause loss of control at high speed.

- Damage to subframe fastenings (the bolts begin to “walk” in the holes, which leads to corrosion).

- Increased load on shock absorbers and their premature failure.

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing silent blocks with ŠKODA Octavia Tour. Here are the most common of them:

1. Using old bolts

Bolts securing arms and subframe to Octavia Tour designed for single use. When re-tightened, they do not provide the required torque, which leads to backlash. Always buy new bolts (their part numbers are indicated in the catalog ETKA).

2. Incorrect pressing

If silent block is installed skewed, it will last 2–3 times less. Always use mandrels and check alignment before pressing. On Octavia Tour A7 Rear control arms often require mandrels with a diameter of 42 mm and 52 mm.

3. Ignoring wheel alignment

After replacing silent blocks (especially the front ones) necessarily need to do a wheel alignment. Even a slight change in wheel alignment angles leads to:

  • 🚗 I pull the car to the side.
  • 🔥 Uneven wear of tires (in 5–10 thousand km you can “kill” new tires).
  • 🛣️ Deterioration of controllability at high speed.

4. Work without a torque wrench

Suspension bolts on Octavia Tour require precise tightening. For example:

  • Front arm bolt to subframe - 80 Nm + 90°.
  • Tie bolt - 50 Nm + 45°.
  • Stabilizer bolt - 25 Nm.

Over-tightening leads to deformation of the silent blocks, under-tightening leads to backlash.

💡

The most common mistake is pressing silent blocks without mandrels. This leads to rubber rupture after 10–15 thousand km.

The cost of replacing silent blocks in the service vs doing it yourself

If you are not confident in your abilities, replacing silent blocks with ŠKODA Octavia Tour can be trusted to professionals. However, the cost of service work often exceeds the price of the spare parts themselves. Let's look at average prices in Russia (for 2026):

Type of work Cost (rubles), itself. work Cost (rubles), service Opening hours
Replacement of front silent blocks (2 pcs.) 0 (spare parts only) 3 500–6 000 2–3 hours
Replacement of rear silent blocks (thrust rods) 0 (spare parts only) 5 000–8 000 3–4 hours
Replacement of silent blocks of front levers (set) 1,500–3,000 (spare parts) 7 000–12 000 4–5 hours
Wheel alignment (after replacement) 1 500–2 500 1 500–2 500 1 hour

As can be seen from the table, self-replacement allows you to save up to 70% of the cost. However, if you do not have experience working with suspension or a special tool (for example, a puller), it is better to contact a service center - errors during replacement can be more expensive.

Advice: if you decide to change the silent blocks yourself, agree in advance with the service about checking the work after replacement. Many service stations offer this service for a nominal fee (500–1,000 rubles).

FAQ: Frequently asked questions about replacing silent blocks on Octavia Tour

Is it possible to drive with worn silent blocks?

Short term - yes, but this leads to:

  • Accelerated wear of tires and other suspension elements.
  • Deterioration in handling (especially on wet roads).
  • There is a risk of the lever or jet thrust coming off on a large bump.

We recommend replacing them at the first sign of wear.

How often do you need to change the silent blocks on the Octavia Tour?

Service life depends on operating conditions:

  • City mode: 80–120 thousand km.
  • Aggressive driving/bad roads: 50–80 thousand km.
  • Low quality rubber: 30–60 thousand km.

Check their condition every 20 thousand km on a lift.

Is it possible to replace only one silent block and not a pair?

Technically yes, but not recommended. Even if the second silent block looks normal, it is already worn out and will soon require replacement. It is better to change in pairs to avoid imbalance in the suspension.

Which silent blocks are better: rubber or polyurethane?

Polyurethane (Powerflex, Whiteline) last longer and withstand loads better, but:

  • 2–3 times more expensive.
  • Stiffer (impairs comfort on bad roads).
  • They require precise installation (if there is a mistake they quickly break).

For everyday driving, high-quality rubber tires are optimal (Lemforder, TRW).

Is it necessary to do a wheel alignment after replacement?

Definitely! Even if you only replaced the rear silent blocks, the suspension geometry changes. Without wheel alignment:

  • The car will be “driven” to the side.
  • The tires will begin to wear unevenly.
  • Fuel consumption will increase (due to increased rolling resistance).
