Rear shock absorbers ŠKODA Octavia A5 (including restyled versions 2008–2013) is a critical suspension element that affects handling, comfort and safety. Over time, they wear out: knocking noises appear, road grip deteriorates, and the car begins to “sag” on bumps. If you notice these symptoms, it's time to consider a replacement. A car service center will charge from 3 to 6 thousand rubles for such work, but if you have the tools and minimal skills, you can do it yourself, saving time and money.
In this article we will analyze in detail the entire process: from diagnosing a fault to installing new shock absorbers. We will pay special attention typical mistakesthat beginners admit, and nuances specific to Octavia A5 (for example, working with suspension springs and body mounts). We will also provide a comparative table of original and analog spare parts so that you can choose the best option in terms of price and quality.
Signs of wear on rear shock absorbers: when is it time to change them?
Rear shock absorbers Octavia A5 serve on average 80–120 thousand km, but this period may be shortened due to aggressive driving, bad roads or manufacturing defects. Here are the key symptoms indicating the need for replacement:
- 🔊 Knocks or squeaks in the rear of the car when driving over bumps (even small ones). Most often the sound comes from worn bushings or torn boots.
- 🌊 "Rocking" of the body after hitting a bump, the car cannot stabilize for a long time, as if it were “floating” along the road.
- 📉 Rear sag when loading the trunk or passengers. Normally, the clearance should remain the same.
- 🚗 Deterioration in handling at high speeds or during sudden maneuvers (for example, skidding of the rear axle).
- 💧 Oil leaks on the shock absorber body - a sign of depressurization and loss of performance.
If you notice at least 2-3 of these signs, it is recommended to conduct a diagnosis. The simplest test: press hard on the rear bumper and release. If the body does more 1–2 vibrations Before stabilization, it’s time to change the shock absorbers. Also inspect them visually - cracks on the boots or traces of corrosion on the rod indicate imminent failure.
⚠️ Attention: On Octavia A5 with a rear multi-link suspension, wear on the shock absorbers can lead to accelerated destruction of the silent blocks of the levers and wheel bearings. Ignoring the problem will result in more expensive repairs!
- Every 10,000 km
- Once a year
- Only when knocking occurs
- Never checked
Which shock absorbers to choose: original vs analogues
For ŠKODA Octavia A5 (including versions with liftback and station wagon bodies) several types of shock absorbers are suitable. Original parts from VW Group are indicated by the articles:
- 🔧 1Z1 513 023 F — right rear shock absorber (for cars without air suspension).
- 🔧 1Z1 513 024 F — left rear shock absorber.
However, original spare parts are expensive (from 5 to 8 thousand rubles apiece), so many owners choose analogues from trusted brands. Below is a comparison table with popular options:
| Brand | Article | Price (per piece), rubles | Features | Recommendation |
|---|---|---|---|---|
| VW/SKODA (original) | 1Z1 513 023 F / 1Z1 513 024 F | 5 000–8 000 | Guaranteed quality, long service life | ⭐⭐⭐⭐⭐ |
| Boge | 30-6451 / 30-6452 | 3 500–4 500 | Good price/quality ratio, softer than the original | ⭐⭐⭐⭐ |
| Sachs | 315 371 / 315 372 | 4 000–5 000 | Stiffer than the original, suitable for sporty driving | ⭐⭐⭐⭐ |
| Monroe | G4548 / G4549 | 3 000–4 000 | Budget option, average resource | ⭐⭐⭐ |
| Kayaba (KYB) | 344357 / 344358 | 3 800–4 800 | High resource, but rigid (may affect comfort) | ⭐⭐⭐⭐ |
When choosing, consider your driving style: For comfortable city use will fit Boge or original. For active driving it's better to take Sachs or KYB. Budget option — Monroe, but be prepared to replace it after 60–80 thousand km.
Important: on Octavia A5 with 1.8 TSI and 2.0 TSI engines (especially in RS versions), it is recommended to install shock absorbers with enhanced characteristics (for example, Sachs or KYB), since standard ones may not cope with increased loads.
Tools and materials for replacement
To change the rear shock absorber to Octavia A5, you will need the following set of tools:
Jack and supports (or lift)
Set of sockets (13, 16, 18 mm) and ratchet wrench
21 mm socket wrench (for stem nut)
Spring puller (required!)
Hammer and pry bar
WD-40 or similar penetrating lubricant
Torque wrench (optional)
Pliers and screwdrivers (phillips, flat)
New shock absorbers + set of boots and bump stops (if replacement is required)
-->
Also prepare wheel chocks and safety stands — working under a car that is supported only by a jack is extremely dangerous! If you don't have a spring puller, it's best not to take risks: a compressed suspension spring can cause serious injury if uncontrolled.
⚠️ Attention: On Octavia A5 with rear multi-link suspension when replacing shock absorbers necessarily check the condition of the bolts securing the arms to the body (part number 1K0 505 377). They often rust and can break when unscrewed. Buy new ones in advance (they cost ~200 rubles apiece).
Step-by-step instructions for replacing the rear shock absorber
The replacement process is the same for both sides, but it’s better to start with right shock absorber (on the passenger side), since it’s easier to get to the top mount there. Follow this algorithm:
Step 1: Preparing the car
1. Place the car on a flat surface, engage first gear (or “P” for automatic transmission) and place stands under the front wheels.
2. Loosen the rear wheel nuts on the replacement side, but do not remove it completely.
3. Raise the rear of the car with a jack, install a safety stand and remove the wheel.
Step 2: Removing the old shock absorber
1. Unscrew the two bolts securing the shock absorber to lower arm (16 mm head). If they are stuck, apply WD-40 and wait 10-15 minutes.
2. In the passenger compartment, fold back the trunk trim and find the upper shock absorber mount (under the decorative plug). Unscrew the rod nut with a 21 mm wrench, holding the rod from turning with a 6 mm hexagon.
3. Carefully remove the shock absorber along with the spring. If it is stuck, lightly tap the wood spacer with a hammer.
Before removing the shock absorber, take a photo of its position relative to the spring and levers - this will help you install the new one correctly.
Step 3: Disassembly and Installation of New Shock Absorber
1. Install the spring puller and compress the spring until the tension is released. Only then unscrew the stem nut!
2. Remove the old shock absorber and check the condition anther, bumper and upper support bushings. Replace them if necessary.
3. Transfer all the parts to the new shock absorber, observing the order: bump stop → boot → spring (bottom down!). Tighten the stem nut with a torque wrench 50–60 Nm.
Step 4: Installation and final assembly
1. Insert the shock absorber into place, aligning the lower bolts with the holes in the arm. Do not tighten them completely!
2. Secure the upper part of the shock absorber to the body and attach the rod nut.
3. Make sure the spring is level (no distortion), then tighten all fasteners. The tightening torque of the lower bolts is 80–100 Nm.
4. Install the wheel, lower the car and check the suspension by rocking the body with your hands.
After replacing the shock absorbers on the Octavia A5, be sure to check and, if necessary, adjust the wheel alignment of the rear wheels. Even slight misalignment can cause uneven tire wear.
Common mistakes and how to avoid them
Even experienced car owners sometimes make mistakes when replacing shock absorbers. Here are the most common of them using an example: Octavia A5:
- 🔧 Incorrect tightening of nuts. If you tighten the rod nut, the shock absorber will work hard, and if you don’t tighten it enough, a knock will appear. Use a torque wrench!
- 🔄 Mixed up sides. Shock absorbers on Octavia A5 not interchangeable: right and left have different threads on the rod. Check the labeling!
- 🔩 Ignoring rusty bolts. The bolts attaching to the lever often stick. If they are not treated with WD-40 in advance, they may break, which will require replacement of the lever.
- 🌀 Failure to follow the assembly order. For example, if you forget to install a bump stop or mix up the top/bottom of the spring, the shock absorber will quickly fail.
- 🚗 No camber adjustment. After replacing the rear shock absorbers with Octavia A5 Wheel alignment angles change, which leads to accelerated tire wear.
Another common problem is boot damage during installation. To avoid this, lubricate its inner surface with silicone grease. Also, do not use a hammer to drive in bolts - this will distort the threads.
What to do if the shock absorber cannot be removed?
If the shock absorber is stuck in the lower control arm, try the following:
1. Treat the mounting area with penetrating lubricant and wait 30 minutes.
2. Gently tap the lever through a wooden block (not the shock absorber!).
3. Use the pry bar as a lever against the body.
4. As a last resort, cut the bolts with a grinder, but then you will have to buy new ones.
Is it worth replacing shock absorbers in pairs?
This issue causes a lot of controversy. On the one hand, pair replacement provides uniform suspension operation and prevents imbalance in handling. On the other hand, if one shock absorber is still in good condition, why spend money on a second one?
On ŠKODA Octavia A5 the recommendations are:
- If the car's mileage less than 100 thousand km, and the second shock absorber shows no signs of wear, only one can be replaced.
- If the mileage more than 100 thousand km or the second shock absorber is also leaking, it is better to replace both.
- On cars with air suspension (optional for top versions) must be changed in pairs, since the difference in hardness will lead to incorrect operation of the system.
Also keep in mind that even if the second shock absorber looks normal, its life is already running out. After 10–20 thousand km you will still have to return to this procedure.

FAQ: Frequently asked questions about replacing rear shock absorbers
Is it possible to replace the rear shock absorber on an Octavia A5 without a spring remover?
Theoretically it is possible, but it is extremely dangerous! The suspension spring is under enormous tension and can “shoot” when the rod nut is loosened, causing serious injury. If you don’t have a puller, it’s better to contact a service center or borrow a tool from a friend.
How long does it take to replace one shock absorber?
If you have experience and tools - approx. 1.5–2 hours sideways. Beginners may need up to 3-4 hours, especially if the bolts are boiling. We recommend that you spend the whole day at work so as not to rush.
Do I need to do a wheel alignment after replacement?
Yes, definitely! On Octavia A5 rear suspension is multi-link, and the replacement of shock absorbers affects the angles of the wheels installation. If you ignore the adjustment, the rubber will wear unevenly, and the car can "take" away.
Which shock absorbers are better – gas or oil?
For Octavia A5 optimal choice - gas-oil shock absorbers (for example, Sachs or KYB Excel-G). They combine the comfort of oil and the reliability of gas, cope better with loads and heat less. Pure oil is cheaper, but loses its characteristics faster, and gas can be too rigid for urban driving.
Can I drive with a knocking shock absorber?
Short term (a week or two) yes, but it is fraught with:
Accelerated wear of other suspension elements (silent blocks, hub bearings).
Deterioration of handling, especially at high speeds.
- Risk of depressurization of shock absorber and oil leakage to brake pads (on some versions) Octavia A5 The shock absorber is located close to the brake mechanism).
Don't put off repairs for long!
