Anti-roll bar struts on Škoda Octavia A7 (including restyled versions 2017–2023) is one of those suspension elements that wear out faster than others. Owners often ignore the first signs of a malfunction, attributing knocks and play to “road features” until the problem begins to threaten safety. In this article we will look at how diagnose strut wear without a lift, what Article numbers of original and non-original parts are they suitable for different engines, and is it possible to replace them yourself without specialized tools?
Feature Octavia A7 — sensitivity of the struts to the quality of the road surface. Even with careful driving, the resource rarely exceeds 60–80 thousand km, and on Russian roads it can be reduced to 30–40 thousand km. At the same time replacing struts on this model requires a mandatory check of the condition of the stabilizer bushings and silent blocks of the levers - their wear accelerates the destruction of new struts by 2-3 times.
Signs of malfunction of stabilizer struts on Octavia A7
The first symptoms of the problem often appear when driving over speed bumps or making sharp turns. Here are the key signs to look out for:
- 🔊 Knocking or clicking noises in the front suspension when driving over uneven surfaces (especially noticeable at low speeds). The sound is often confused with wear of shock absorbers, but with struts it is drier and more distinct.
- 🚗 Deterioration of stability when turning: the car begins to “fall” to one side and requires constant steering. This is due to the fact that the stabilizer ceases to effectively distribute the load between the wheels.
- 🛣️ Vibrations on the steering wheel when braking or accelerating on uneven roads. Occurs due to play in the hinge joints of the struts.
- 🔧 Uneven tire wear (especially the inside of the tread). This is an indirect sign, but in combination with other symptoms confirms the problem.
It is important to distinguish the malfunction of the struts from the wear of other suspension elements. For example, knocking noise when passing potholes The steering rack and support bearings may also cause problems. For an accurate diagnosis, use the “swinging” method:
⚠️ Attention! Do not check the play of the struts while hanging (by lifting the car with a jack) - this is dangerous and ineffective. The best way: load the suspension (for example, rock the car up and down by the wing) and listen to the sounds. Worn struts will make a distinct metallic knocking noise.
- Once every 10 thousand km
- Only when knocking occurs
- Before the seasonal tire change
- Never checked
Articles and analogues of stabilizer struts for Octavia A7
On Škoda Octavia A7 (including versions with 1.4 TSI, 1.6 MPI, 1.8 TSI and 2.0 TDI engines) stabilizer struts with different part numbers are installed depending on the type of suspension and year of manufacture. Original parts are produced by the company TRW (part of the group ZF), but there are high-quality analogues on the market from Lemförder, Febi and Sidem.

When choosing analogues, pay attention to anther material - with cheap Chinese spare parts they often crack after 10-15 thousand km. The best option in terms of price/quality ratio - Febi or TRW. For a sporty driving style (for example, on Octavia RS) reinforced racks from Meyle HD or Sidem Sport.
Before purchasing, check to see if the kit includes new nuts and bolts. On the Octavia A7 they often “stick” to the racks, and reusing old fasteners is unacceptable.
Step-by-step instructions for replacing stabilizer struts
Replacing racks with Octavia A7 does not require special tools, but will require an inspection hole or a lift. Working time is 1–1.5 hours for both sides. Here's what you'll need:
- 🔧 Spanners for
16and18(or ratchet heads). - 🔩 Socket wrench on
13to unscrew the fastening of the strut to the stabilizer. - 🛠️ WD-40 or similar penetrating lubricant (for soured nuts).
- 🔧 Torque wrench (optional for proper tightening).
Sequence of actions:
- Preparation: Secure the rear wheels with the handbrake, lift the front of the car and remove the wheels. Treat the strut mounting nuts with WD-40 (especially the top ones, which often stick).
- Removing the old stand:
- Unscrew the nut securing the strut to the shock absorber (the key is on
18). - While holding the post finger with the key on
16, unscrew the nut from below (the wrench is on13). - Remove the stand; you may have to pry it off with a pry bar.
- Unscrew the nut securing the strut to the shock absorber (the key is on

⚠️ Attention! On Octavia A7 with 2.0 TDI engines (especially after 2019), the stabilizer links may have different lengths for left and right side. It is impossible to confuse them during installation - they simply will not fit into place, but this is worth considering when purchasing.
Common replacement mistakes and how to avoid them
Even experienced car owners make mistakes that shorten the service life of new struts. Here are the most common:
- 🔧 Reusing Old Nuts. On Octavia A7 nuts for fastening the racks are disposable (have a plastic insert for fixation). Their repeated use leads to self-unscrewing.
- 🛠️ Incorrect tightening. Tightening too weak leads to play, too strong - to damage the rubber bushings. Optimal moment:
40–50 Nm. - 🚗 Ignoring stabilizer bushings. If they are worn out, new racks will last 2-3 times less. Check their condition before installation.
- 🔊 Lack of lubrication. Be sure to process the threads of the new racks copper grease or graphite spray - this will prevent corrosion and make future replacement easier.
Another typical problem is anther reupholstery during installation. They must sit freely, without tension, otherwise they will quickly tear. If the boot is too tight, trim its edge with a knife (but no more than 5 mm).
What to do if the stand does not unscrew?
If the nut is stuck to the strut pin, do not try to force it off - this may break the pin. Instead:
1. Water the joint generously with WD-40 and wait 10-15 minutes.
2. Tap the edges of the nut with a hammer (not your finger!).
3. Use a spanner wrench instead of an open-end wrench - it breaks edges less.
4. As a last resort, cut off the nut with a grinder (carefully so as not to damage the threads on the shock absorber).
Rack service life: when should I expect a replacement?
Lifetime of stabilizer struts Octavia A7 depends on several factors:
- 🛣️ Road quality: on Russian highways the average mileage before replacement is 40–60 thousand km. In Europe, this figure can reach 80–100 thousand km.
- 🚗 Driving style: aggressive acceleration and braking, frequent off-road trips reduce the resource by 30–40%.
- 🔧 Quality of spare parts: original racks (TRW) last longer than analogues, but also cost 20–30% more.
- 🌡️ Climatic conditions: in regions with frequent temperature changes (for example, Siberia), the rubber elements of the struts harden and crack faster.
The manufacturer recommends checking the condition of the racks every 30 thousand km, but in practice this should be done more often - once every 15–20 thousand km, especially if you drive on gravel roads or frequently load your car. Please note condition of anthers: if they are cracked, the rack will last no more than 5–10 thousand km, even if it itself is still intact.
Replacing the racks in pairs (both at once) is not necessary, but is recommended. If one strut is worn out, the second usually does not lag behind by more than 10–15 thousand km.
Should I change the struts myself?
Replacing stabilizer struts with Octavia A7 refers to operations of medium complexity. If you have experience working with suspension (for example, you have already changed shock absorbers or silent blocks), then you can handle struts. However, there are nuances that make the task non-trivial:
Advantages of self-replacement:
- ✅ Saving 1,500–2,500 rubles (cost of work at a service station).
- ✅ The opportunity to personally check the quality of new parts and the tightening of fasteners.
- ✅ Experience that will be useful for other suspension work.
Disadvantages and risks:
- ❌ There is a possibility of stripping the threads on the shock absorber (if the nuts are very acidic).
- ❌ Risk of improper tightening, which will lead to play or breakage of the strut.
- ❌ The need to purchase specialized tools (for example, a socket wrench for
13with extension cord).
If you have never worked with a suspension, it is better to entrust the replacement to professionals. Errors when installing racks can lead to loss of control at high speed, especially at Octavia RS or versions with all-wheel drive (4x4).
FAQ: Frequently asked questions about Octavia A7 stabilizer struts
Is it possible to drive with a broken stabilizer link?
Short-term (1-2 days) - yes, but with caution. Driving for a long time with a faulty strut leads to:
- Accelerated wear of silent blocks of levers and stabilizer bushings.
- Deterioration in handling, especially on wet roads.
- Uneven tire wear (may require balancing after strut replacement).
At speeds above 100 km/h, the risk of losing control of the car increases by 2–3 times.
How to distinguish the knock of struts from the knock of shock absorbers?
Knock of racks:
- Clear, metallic, audible when driving over small irregularities (for example, asphalt joints).
- More often occurs at low speeds (20–40 km/h).
- Can be heard when rocking the machine manually (if the stand is completely broken).
Shock absorber knock:
- Dull, “gurgling”, heard when driving through large potholes.
- Intensifies at high speeds.
- Accompanied by body rocking after hitting an obstacle.
Do I need to do a wheel alignment after replacing the struts?
No, replacing stabilizer links no effect on the wheel alignment angles. However, if you notice that the car has begun to “steer” to the side, check:
- The racks are installed correctly (the left and right ones may be mixed up).
- The condition of the silent blocks of the levers - their wear may require camber adjustment.
- Tire pressure (a difference of even 0.2 atm can cause wheel slip).
Which racks are better - original or analogues?
Depends on budget and driving style:
- Original (TRW): optimal for most owners. Resource - 50–70 thousand km, good price/quality ratio.
- Lemförder or Febi: 20-30% cheaper than the original, resource - 40-60 thousand km. Suitable for a quiet ride.
- Meyle HD or Sidem Sport: reinforced struts for aggressive driving (e.g. Octavia RS). More expensive than the original, but last up to 80–100 thousand km.
- Budget analogues (for example, Topran): resource - 20–30 thousand km. Suitable only as a temporary measure.
Avoid spare parts without a brand or with inscriptions like “Made in China” without indicating the manufacturer - their service life rarely exceeds 10 thousand km.
Is it possible to restore the stabilizer links?
Technically yes, but inappropriate. Recovery involves:
- Replacing the hinge pin (if it is loose).
- Installation of a new boot and lubricant.
- Checking threaded connections.
However, the cost of labor and spare parts often exceeds the price of a new rack. In addition, restored racks last 2–3 times less than new ones. The exception is rare cases where the strut breaks due to mechanical damage (for example, an impact) rather than natural wear and tear.
