Rear shock absorbers Ε koda Octavia Tour - a critical element of the suspension, on which not only comfort, but also control safety depends. Over time, even the original struts lose their effectiveness: knocking noises appear, the car begins to βrockβ on uneven surfaces, and the braking distance increases by 10β15%. If you notice that the car βsquatsβ under heavy braking or the passage of speed bumps is accompanied by loud impacts, itβs time to think about replacing it.
In this article we will analyze the entire process from A to Z: how to diagnose shock absorber wear, what spare parts to choose (original vs analogues), what tools will be needed, and how to replace them yourself without making common mistakes. We will pay special attention to the nuances for different generations Octavia Tour (A5, A7, FL), since their suspension design is different. We will also provide a comparison table of popular manufacturing brands and give recommendations for running in new racks.
Signs of wear on rear shock absorbers: when is it time to change them?
Rear shock absorber service life Ε koda Octavia Tour depends on operating conditions, but on average it is 80β120 thousand km. However, there are a number of symptoms that indicate the need for replacement long before this mileage:
- π Knocks or squeaks in the rear of the body when driving over uneven surfaces (even at low speed).
- π Body rocking after overcoming speed bumps or potholes, the car cannot stabilize for a long time.
- π Increased braking distance due to βdiveβ of the rear axle during sudden braking.
- π§ Oil leaks on the shock absorber body (visible during visual inspection).
- π Uneven rear tire wear - a sign that the wheel βbouncesβ when moving.
Particularly dangerous is the wear of shock absorbers on Octavia Tour with a loaded trunk or trailers: weight distribution is disrupted and the vehicle becomes uncontrollable at high speeds. You can check the condition of the struts with a simple test: press firmly on the rear bumper and release. If the body does more 1β2 vibrations - It's time to change the shock absorbers.
β οΈ Attention: On models Octavia Tour A7 FL (2017+) with systemDCC(dynamic chassis) shock absorber wear may be indicated by an errorP1650on the dashboard. In this case, diagnostics is required not only of the mechanical part, but also of the electronic control unit.
Choice of rear shock absorbers: original or analogues?
There are more than 20 brands on the market that produce shock absorbers for Ε koda Octavia Tour, but not all of them are equally reliable. Original racks from VW Group (article 6Q0 513 025 for A5, 5Q0 513 025 for A7) guarantee factory quality, but their price often exceeds 8β10 thousand rubles per piece. An alternative is proven analogues:
| Brand | Article (A5/A7) | Price per piece, rubles | Features |
|---|---|---|---|
| Monroe | E3497 / E3498 |
4 500β5 500 | Softer than the original, good for a comfortable ride |
| Boge | 23-0580 / 23-0581 |
5 000β6 000 | Stiffer, suitable for sporty driving style |
| Sachs | 315 371 / 315 372 |
6 000β7 000 | Optimal price/quality balance, often installed on the conveyor |
| KYB | 344404 / 344405 |
4 000β4 800 | Budget option, but the resource is 20β30% lower |
When choosing, pay attention to shock absorber type:
- π Oily - cheaper, but less durable (suitable for quiet driving).
- β‘ Gas-oil β stiffer, better road holding at high speeds.
- π§ With adjustable stiffness - only for versions with
DCC(requires programming after replacement).
- Original (VW/Skoda)
- Monroe/Sachs
- Boge/KYB
- Other brands
- I don't know
β οΈ Attention: On Octavia Tour A5 (2004β2013) rear shock absorbers often βdieβ along with the support cups and springs. If the mileage is greater 150 thousand km, it is recommended to change the entire set, otherwise the new racks will last 2 times less.
Necessary tools and preparation for replacement
To replace rear shock absorbers with Ε koda Octavia Tour you will need:
- π§ Set of sockets and keys (required on
13,16,18,21). - π© Torque wrench (shock absorber nut tightening torque - 50β60 Nm).
- π¨ Spring puller (if you plan to disassemble the rack completely).
- π οΈ WD-40 or equivalent - rusty bolts on Octavia Tour meet often.
- π Jack and stops (or a lift if there is access).
- π§€ Gloves and safety glasses - the springs are under tension!
Before starting work:
- Park your car on flat surface and lock the front wheels.
- Loosen the wheel nuts before getting up on a jack.
- Disconnect the negative terminal of the battery (if you have a version with
DCC).
βοΈ Preparing to replace shock absorbers
On Octavia Tour A7 (2013+) rear shock absorbers are attached to the body through rubber-metal bushings, which often βstickβ to the bolts. If they are not replaced along with the struts, a knock will appear after 10β20 thousand km.
Step-by-step instructions for replacing rear shock absorbers
Replacement process Ε koda Octavia Tour takes 2β3 hours (excluding preparation). The main thing is to be consistent and not to rush. Below is the instruction for the models A5/A7 (for FL details are indicated separately).
Step 1: Removing the old shock absorber
1. Raise the rear of the car on a jack and remove the wheel.
2. Unscrew the two bolts securing the shock absorber to suspension arm (head on 18).
3. In the passenger compartment or trunk, bend back the trim and unscrew the top nut securing the strut to the body (the head is on 13 or 16, depends on the year).
4. Carefully remove the shock absorber along with the spring (if the strut is not removable, the spring will remain on the car).
Step 2: Installing a New Shock Absorber
1. If the strut is collapsible, transfer the spring and boot to the new shock absorber using a puller.
2. Place the stand in place, starting with bottom mount (do not tighten the bolts all the way!).
3. Attach the upper part of the shock absorber to the body and tighten the nut firmly 20β25 Nm.
4. Lower the car onto its wheels and final but tighten all bolts (moment - 50β60 Nm for the lower ones, 30β35 Nm for the top ones).
Features for Octavia Tour A7 FL
On models with a DCC system, after replacing shock absorbers, it is necessary to carry out adaptation through a diagnostic scanner (VCDS, ODIS). Without this, the system will generate an error and operate in emergency mode. Also on FL versions, the upper shock absorber mount can be covered with a plastic panel - it must be carefully removed so as not to break the latches.
Step 3: Check after replacement
After installing the new racks:
- π Bleed the suspension by pressing the rear of the body several times.
- π Drive 5-10 km on uneven roads and check for knocking noises.
- π§ After 500 km check the tightness of the nuts - they may weaken.
If after replacing the shock absorbers the car has become βharderβ than before, do not panic - the new struts need to be broken in. After 500β1000 km they will βget used toβ and comfort will return.
Typical replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to premature failure of shock absorbers. Here are the most common:
- π§ Reusing old nuts and bolts - they become deformed when tightened and may burst.
- π οΈ Incorrect tightening torque β weak tightening leads to backlash, excessive tightening leads to thread cutting.
- π Replacing only one shock absorber - always change in pairs, otherwise the car will βsteerβ to the side.
- π§ Ignoring anthers and bump stops β without them, the rack will last 2 times less.
- π Failure to check wheel alignment β after replacing the rear shock absorbers, the angles may change!
On Octavia Tour A5 With a mileage of more than 150 thousand km, the silent blocks of the rear control arms often wear out. If they are not replaced along with the shock absorbers, knocks and vibrations will remain, and the new struts will work under increased load.
The most critical mistake is not tightening the lower shock absorber mounting bolt. On uneven surfaces, it can spin, which will lead to loss of control at speed.
Run-in and care after replacement
New shock absorbers require running-in - first 500β1000 km avoid:
- π Sudden acceleration and braking.
- π Driving off-road or in deep potholes.
- π§ Overload of the trunk (maximum 70% of the permissible weight).
Via 1β2 thousand km check:
- π§ Tightening all fasteners.
- π§ No oil leaks on the strut body.
- π― Even rear tire wear.
If shock absorbers gas-oil, their stiffness may decrease slightly after running in - this is normal. But if after 5 thousand km there are knocks or oil on the body, this is a defect or incorrect installation.
FAQ: Frequently asked questions about replacing rear shock absorbers
Is it possible to replace the rear shock absorbers on an Octavia Tour yourself without a pit?
Yes, but it's more complicated. You will need a jack with stops and good access to the top mount racks (in the trunk or interior). On A7 FL the top nut may be hidden under the casing - it will have to be removed.
How long do the rear shock absorbers on the Octavia Tour last in Russian conditions?
On average 60β80 thousand km when driving around the city and on the highway. On bad roads the resource is reduced to 40β50 thousand km. Gas oil struts (Boge, Sachs) live longer than oil ones (KYB).
Is it necessary to do a wheel alignment after replacement?
On Octavia Tour rear camber is not adjustable, but toe may change due to shifting of the levers. If the car is βdrivingβ to the side or eating rubber, check the corners.
Can shock absorbers from other VW models be installed?
Yes, but only if the article numbers match. For example, racks from VW Golf IV suitable for Octavia Tour A5, and from Passat B6 - for A7. Always check the catalogs ETKA or Elcats.
What happens if you don't change worn shock absorbers?
In addition to discomfort, you risk:
- π₯ Overheating of brake discs (braking distance increases).
- π Loss of control at speed (hydroplaning, βyawβ).
- π₯ Destruction of other suspension elements (step bearings, silent blocks).
