Car suspension Skoda Octavia A5 It is famous for its reliability, but even it is subject to natural wear. Rear shock absorbers play a critical role in comfort and safety, especially when passing unevenness or sharp braking. If you notice a knock in the back of the body, the appearance of oil stains on the racks or deterioration of handling, it is time to think about repairs.
Many owners try to postpone a visit to the service, trying to save money, but ignoring the symptoms of wear and tear can lead to more serious breakdowns. For example, overloading other elements of the suspension or taking the car aside during emergency braking. In this article, we will discuss how to make a replacement yourself, what parts to choose and what to pay special attention to when working with the rear axle.
Suspension symptoms and diagnostics
The first sign that the shock absorbers Skoda Octavia A5 served their term, is a characteristic knock when passing by lying policemen or pits. This sound usually comes from the back of the body and can be heard even with the windows closed. However, not always knocking indicates a breakdown of the shock absorber; the problem may lie in the Silent blocks or the sleeve of stability.
Visual examination is the most affordable diagnostic method. If you see traces of oil leakage on the case of the rack, this is an unambiguous signal to replace. The dry rack may be serviceable, but the wet rack is no longer. Pay attention to the condition of rubber breakers and anthers, as their destruction accelerates the wear of the shock absorber rod.
Another indirect sign is uneven wear of tires. If the tread is erased by spots or faster on one side, this can indicate a loss of suspension efficiency. It is also worth checking the work. rear beam - on Octavia A5 It often tends to deform when hit hard, which changes the geometry of the wheel.
When driving at high speed, there may be a "swimming" of the car's stern. The car becomes less stable in cornering and you have to adjust the trajectory more often with the steering wheel. This is a dangerous condition that requires immediate intervention.
Selection of spare parts: Original or analogues?
The auto parts market offers a huge selection of replacement options. Original shock absorbers from Skoda (production Lenze or Sachs) ensure conformity with factory performance, but their price is often overpriced. For budget repairs, high-quality analogues from well-known brands will be suitable.
When choosing, you should focus on proven manufacturers. Monroe, KYB (Kayaba) and Sachs It is considered the gold standard for the Volkswagen Group. They provide a balance between comfort and handling, which is laid down by the plant engineers. Budgetary options such as Patron or AsvaThey may not last long and are often hard-core.
- 🔧 Monroe A great choice for comfortable driving, often goes as original.
- ⚙️ KYB - Harder racks, suitable for sports riding and bad roads.
- 💰 Sachs - premium quality, high price, but long resource.
It is important to consider that Octavia A5 The back suspension is a non-cut beam. Shock absorbers here do not change separately, but require replacement in pair. Installing a new rack on only one side will lead to unbalanced suspension and the car moving aside during braking.
Necessary tools and preparation
For a good replacement, you’ll need a standard toolkit, but some specific keys will speed up the process. Be sure to prepare a jack and reliable safety stands (goats), as it is dangerous to work under the car without them. A regular garage jack does not provide sufficient stability.
You will need: a rattle handle, a set of heads (including keys for 13, 15, 17 and 18 mm), an extension cord, a collar, a hammer and a penetrating lubricant type WD-40 or lysol. To remove old bolts, a balloon key may be needed to turn the wheel if the bolt does not unscrew.
Before starting work, make sure that the car is on a flat surface with the hand brake on. Under the front wheels it is better to put recoil stops or bricks. This will eliminate the risk of rolling the car while lifting the rear.
Pay special attention to the preparation of threaded connections. If the bolts are very boiling, treat them with abundantly penetrating lubricant and let them stand for 10-15 minutes. An attempt to tear off a rusted bolt without preparation can lead to its failure or breakage of the key.
Step-by-step replacement instructions
The replacement process begins with loosening the wheel mount bolts while the car is still on the ground. Lift the back of the car with a jack under a reinforced beam and install on the stand. Remove the wheel to access the suspension nodes.
The upper support of the shock absorber is in the trunk. Remove the plastic decorative stub and unscrew the two nuts of attaching the top cup to the body. Be careful not to drop nuts inside the arch. The lower mount is under the car. Unscrew the bolt connecting the shock absorber to the beam.
After removing old shock absorbers, be sure to check the condition of rubber bushes and anthers. If they are worn out, they need to be replaced, even if you are putting up new racks. Damaged anther will lead to a rapid failure of the new part due to dirt hitting the stock.
Installation of new shock absorbers is carried out in reverse order. Before tightening all bolts, lower the car on the wheel so that the suspension takes the working position. This will eliminate the distortion of rubber bushings and ensure their long service.
- Original (Sachs/Skoda)
- Premium analogues (KYB/Monroe)
- Budget options
- Buy only when broken
☑️ Preparing for replacement
If the bolts do not unscrew, use a heating or impact tool, but carefully so as not to damage the thread of the beam. In some cases, you have to cut old bolts with a Bulgarian if they do not lend themselves.
What to do if the top leg nut is turned?
Use a hexagonal key or a special holder for the shock absorber rod to lock it from spinning while you unscrew the nut. Sometimes holding the rod with pliers helps, but it is risky for threading.
⚠️ Attention! Never tighten the bottom bolt of the shock absorber attachment while the suspension is in a fully compressed state (the machine is on the jack). This will lead to the rupture of rubber bushings at the first passage of irregularities.
Features of working with a beam and Bushings
On Skoda Octavia A5 The back beam has its own design features. Often owners are faced with the fact that the bolts of the shock absorber attach to the beam are stuck dead. In such situations, you should not make excessive efforts not to break the thread in the body of the beam.
Sometimes it is necessary to remove the beam itself to replace the Bushings or rubber bands of the mount. This is a more time-consuming procedure that requires special equipment for pressing. If you only change shock absorbers, make sure the beam has no visible cracks or deformities.
- 🔍 Examine the rubber cushions of the beam attachment to the body - their cracks cause a strong knock.
- ⚙️ Check the condition of the brake tubes passing near the beam so as not to damage them during dismantling.
- 🛠️ Use a dynamometer key to tighten bolts with the force specified in the service book.
If you notice that the beam is shifted relative to the center, this may indicate problems with the Bushings. In this case, simply replacing shock absorbers will not solve the problem of controllability.
Table of recommended characteristics and prices

| Sachs | Super Touring | Oily | 24,000 - 28,000 rubles. | 80 000 - 100 000 |
Before buying new shock absorbers, measure the length of the old ones in a compressed and stretched state to make sure compatibility is in place, especially if you have lift kits installed or undersold.
Safety precautions and common mistakes
Working with suspension requires strict adherence to safety rules. Never be under a car that is held only by a jack. Use only certified stands. Even a small shift can lead to injuries.
One of the common mistakes is the wrong tightening of bolts. Too weak a puff will lead to backlash and knocking, and too strong - to the failure of the thread or deformation of the bushings. Use the dynamometer key to achieve optimal effort.
⚠️ Attention! When you are working with the springs of suspension (if they are removed), be extremely careful. The compressed spring stores tremendous energy and can fly out with fatal consequences if disassembled incorrectly.
It is also not recommended to use gas welding for cutting boiling bolts near fuel tanks and brake lines. It is better to use a Bulgarian or special filmmakers.
Replacing the rear shock absorbers on the ŠKODA Octavia A5 is a work of medium complexity, requiring accuracy and the right tool. Savings on the quality of spare parts can turn into a re-repair after several thousand kilometers.
Diagnosis after installation
After completion of the work, be sure to conduct a control check. Scroll the wheel with your hands to make sure there are no snags. Start the engine and check the brake system - pressing the pedal should not cause extraneous sounds.
The first 100-200 km of operation of the new shock absorbers are run-in. Avoid sharp maneuvers and driving deep pits at high speed. This will allow the rubber elements to finally fall into place.
If after replacement you feel that the car is pulling to the side or the steering wheel vibrates, you need to address the descent-collapse. Although the back beam is on Octavia A5 is not regulated, the change of wheel installation angles can occur due to wear of the Silent blocks or deformation of the beam.
Regular inspection of the suspension will help you avoid unexpected breakdowns. Check the shock absorbers every 10,000 km. Timely replacement of worn suspension parts is the key to your safety and the safety of surrounding road users.
How often do you need to change the rear shock absorbers on an Octavia A5?
The approximate resource is 80,000 - 100,000 km, but this depends on operating conditions. When driving on bad roads, the service life can be reduced to 50,000 km.
Is it possible to change shock absorbers one at a time?
No, shock absorbers are always replaced in pairs on the same axle. Replacing only one strut will unbalance the suspension and deteriorate handling.
Is it necessary to do a wheel alignment after replacement?
On the rear axle Octavia A5 The wheel alignment angles are not adjustable, so wheel alignment is not necessary if the beam mount has not been removed. However, checking the corners won't hurt.
What tools are needed for replacement?
You will need: socket set (13, 15, 17, 18 mm), ratchet, jack, stands, penetrating oil and torque wrench.
What to do if the bolt does not come off?
Apply penetrating lubricant to the joint, tap the bolt head with a hammer, or use heat. As a last resort, cut the bolt with a grinder.
