Replacing shock absorbers on a ŠKODA Octavia A5: a detailed guide with photos and tips

Replacing shock absorbers with ŠKODA Octavia A5 - a task that every owner of this car faces sooner or later. On average, the service life of original racks is 80–120 thousand km, but aggressive driving, bad roads or low-quality spare parts can cut this period in half. If your Octavia started to “sag” on bumps, there was a knock in the suspension or controllability deteriorated - it’s time to think about diagnostics and replacement.

In this article we will analyze the entire process from A to Z: how to determine the wear of shock absorbers, which struts to choose (original, Boge, Monroe or Kayaba), what tools will be needed, and how to replace them yourself without contacting a service center. We will pay special attention typical mistakesthat beginners make, and the nuances of wheel alignment adjustment after repair. If you have never done suspension, don’t worry: with the right approach, the work will take no more than a day.

Signs of shock absorber wear on the ŠKODA Octavia A5

The first question that owners have is: how do you know when it’s time to change the shock absorbers? On Octavia A5 (including restyled versions 1Z3 and 1Z5) symptoms of wear appear gradually, and many attribute them to “road features”. However, ignoring them is dangerous - it affects safety.

Main features:

• 🚗 Increased braking distance - worn shock absorbers do not support the body, and when braking, the weight is redistributed incorrectly.
• 🔧 Knocking in the suspension on uneven surfaces (usually in the front) - may indicate destruction of bushings, oil seals or the rod itself.
• 🌊 "Rocking" of the body after passing speed bumps - if the car “nods” bow or stern for a long time, the struts cannot cope.
• 🛣️ Moving to the side when driving in a straight line - often associated with uneven wear of the front shock absorbers.
• 💡 Oil leaks on the rack body - a clear signal for replacement, even if there are no other symptoms.

On Octavia A5 with engines 1.6 MPI, 1.8 TSI or 2.0 TDI The rear shock absorbers wear out less frequently than the front ones, but they also need to be checked. Struts on cars with a mileage of over 150 thousand km are especially vulnerable - even if outwardly they look normal, their characteristics could deteriorate by 40–50%.

⚠️ Attention: If the knocking noise remains after replacing one shock absorber, check the support bearing and spring. On Octavia A5 they often fail at the same time as the struts.

Which shock absorbers to choose: original vs analogues

The selection of spare parts is the most critical stage. Original shock absorbers from ŠKODA/VW (articles 1Z1 413 031/032 for front and 1Z5 513 025/026 for the rear) guarantee compatibility, but their price is steep: from 8–12 thousand rubles. per piece. An alternative are proven brands:

Brand	Model	Front/Rear	Average price (pieces)	Features
Boge	Pro-Gas	Before	5 500–7 000 ₽	Stiffer than the original, suitable for active driving
Monroe	Reflex	Back	4 800–6 200 ₽	Soft, comfortable for the city
Kayaba (KYB)	Excel-G	Front/Rear	5 000–6 500 ₽	Universal option, close to the original
Sachs	Super Touring	Before	6 000–7 500 ₽	Increased wear resistance, but more expensive than analogues

When choosing, pay attention to shock absorber type:

• 🔄 Oily - cheaper, but less durable, suitable for quiet driving.
• ⚡ Gas-oil — more expensive, but they hold the road better and last longer (we recommend for Octavia A5).

For cars with mileage over 200 thousand km it makes sense to consider reinforced racks (for example, Boge Turbo-Gas), since standard ones can quickly fail due to wear of other suspension elements.

Tools and preparation for replacement

To replace shock absorbers with ŠKODA Octavia A5 do it yourself, you will need:

• 🔧 Set of sockets and keys (required) 13 mm, 16 mm, 18 mm).
• 🔨 Spring puller (can be rented).
• 🛠️ Jack and supports (or lift).
• 🧲 Torque wrench (for tightening to the correct torque).
• 🧴 WD-40 or similar (sticky bolts are a common problem).
• 🔩 New nuts and bolts (we recommend replacing them, especially on the front struts).

Before starting work:

Clear the trunk and interior of heavy objects

Jack up the car and place jack stands on the rear wheels.

Treat all threaded connections with WD-40 the day before replacement.

Prepare a container to drain the oil (if the shock absorbers are leaking)

Take a photo of the location of the wires and tubes (for the front struts) -->

If you change front struts, be sure to disconnect ABS sensor connector (located next to the steering knuckle) and brake hose (carefully so as not to damage!). On the rear shock absorbers there are fewer difficulties, but removal of the trunk trim may be required.

⚠️ Attention: On Octavia A5 with xenon headlights When replacing the A-pillars, it is necessary to remove the bumper so as not to damage the light correctors. If you have little experience, it is better to entrust this to the service.

Step-by-step replacement of front shock absorbers

Front struts on Octavia A5 It is more difficult to change the rear ones due to the need to disassemble the steering knuckle. Follow the algorithm:

1. Remove the wheel and clean any dirt around the stand. Treat the knuckle mounting bolts with WD-40 (18 mm) and upper support nuts (13 mm).
2. Unscrew the brake hose from the bracket on the rack (key 10 mm). Do not kink the hose!
3. Remove the ABS sensor connector (gently pull the latch).
4. Unscrew the two bolts securing the strut to the knuckle (you will need to hold the ball joint pin with a wrench 16 mm).
5. Supporting fist, remove the rack from its seat.
6. Unscrew the three upper support nuts (under the hood, key 13 mm) and remove the stand assembly.

Next, disassemble the rack:

• 🔧 Compress the spring with a puller.
• 🔩 Unscrew the rod nut (wrench 22 mm, hold the rod with a hexagon 6 mm).
• 🔄 Remove the support bearing, cup and spring.

When assembling, use new nuts and bolts, especially for attaching to a fist. Tightening torque:

• Rod nut — 50–60 Nm.
• Knuckle mounting bolts — 100–120 Nm.
• Upper support nuts — 20–25 Nm.

Replacing rear shock absorbers: nuances

Rear shock absorbers Octavia A5 change is easier, but there are some subtleties. The main difficulty is access to the top mount, which is hidden under the trunk trim. Procedure:

1. Remove the trunk trim (snap off the clips and unscrew the screws).
2. Unscrew the top fastening nut (key 13 mm).
3. Jack up the car and remove the wheel.
4. Unscrew the lower mounting bolt (key 16 mm).
5. Remove the shock absorber down, carefully removing the rod from the upper eye.

When installing a new shock absorber:

• 🔧 Check status bushings and anthers - on Octavia A5 they often break after 100 thousand km.
• 🔩 Tighten the nuts only after the car is lowered onto the wheels (otherwise the suspension will be under tension).

Tightening torque:

• Top nut — 25–30 Nm.
• Bottom bolt — 80–100 Nm.

⚠️ Attention: On versions with air suspension (for example, Octavia Scout) replacing shock absorbers requires resetting errors in the control unit. Without diagnostic scanner (eg VCDS) the suspension will not work correctly.

Wheel alignment after replacing shock absorbers

Many owners Octavia A5 They are wondering: is it necessary to do a wheel alignment after replacing the struts? The answer depends on what work was carried out:

• 🔧 If they changed shock absorbers only (without removing the levers and steering knuckles) - the collapse can not be done, but check the alignment.
• 🔄 If filmed knuckle bolts or silent blocks were replaced - camber is required.

In practice, even when replacing only shock absorbers, wheel alignment angles may change due to:

• 📉 Sagging of springs (especially on cars with mileage >150 thousand km).
• 🔩 Play in ball joints or steering rods.
• 🛣️ Uneven tire wear (if the struts have not been changed for a long time).

Wheel alignment cost for Octavia A5 in the service - 1 500–2 500 ₽. If you replaced the struts yourself, it makes sense to check the angles on a bench to avoid uneven tire wear.

Typical mistakes when replacing shock absorbers

Even experienced car owners make mistakes that lead to rapid failure of the struts or deterioration of controllability. Here are the most common:

1. Reusing old nuts and bolts - on Octavia A5 The threads often break off, especially on the A-pillars. New bolts cost a pretty penny, but will save you a lot of hassle.
2. Incorrect tightening — overtightened nuts lead to deformation of the bushings, undertightened ones lead to play. Always use a torque wrench!
3. Ignoring anthers and bump stops — without them, the rack will last 2–3 times less.
4. Replacing only one rack - if both shock absorbers on the axle are worn out, replace them in pairs, otherwise the car will “steer”.
5. No bleeding of new racks — before installation, gas-oil shock absorbers must be fully compressed/decompressed 3–5 times.

Another common problem is brake hose damage when removing the front strut. On Octavia A5 it is attached to a bracket on the rack, and if it is bent, it may burst. Check the hose for leaks after assembly!

What happens if you don't change worn shock absorbers?

In addition to discomfort, worn racks lead to:

- Increased braking distance by 20–30% (risk of accidents!).

- Rapid tire wear (uneven tread).

- Breakage of other suspension elements (levers, silent blocks, wheel bearings).

- Loss of directional stability at speed (the car “floats” in the lane).

On Octavia A5 with worn shock absorbers they often break support bearings (cost from 2,000 rubles per piece).

FAQ: Frequently asked questions about replacing shock absorbers

Is it possible to drive if the shock absorber is leaking?

If the leak is small (a few drops), you can get to the service station, but no more 500–1000 km. A severe leak means the strut has lost gas/oil and is not working. On Octavia A5 This is fraught with breaking through the suspension on bumps and damaging the body.

How long does it take to replace?

If you have the tools and experience:

• 🔧 Front struts - 3–4 hours (with disassembly).
• 🔧 Rear pillars - 1.5–2 hours.

For beginners, it is better to wait the whole day, as problems may arise with stuck bolts.

Do the springs and shock absorbers need to be replaced?

Not necessary if the springs do not have cracks or sagging. However, on Octavia A5 with mileage >150 thousand km, springs often lose elasticity. Check their height: if the difference between the right and left spring is greater 5 mm - change in pairs.

Which shock absorbers are best for a comfortable ride?

Suitable for the city and a relaxed driving style:

• 🔹 Monroe Reflex - soft, absorbs bumps well.
• 🔹 Kayaba Excel-G — balanced, close to the original.

For active driving, choose Boge Pro-Gas or Sachs Super Touring — they are tougher, but they hold the road more accurately.

Is it possible to replace shock absorbers without removing the springs?

Technically yes, if you use special couplers for springs directly on the machine. However, this is dangerous: the spring under load can jump off and cause injury. On Octavia A5 It is better to remove the stand completely and disassemble it on a workbench.
