Car rear suspension Skoda Octavia A5 The 1.6 engine is one of the most reliable in its class, but over time, even it requires intervention. The main problem of owners of sedans and liftbacks is the gradual subsidence of the body, especially from the rear, which violates the geometry of shock absorbers and worsens handling.
Many car owners mistakenly believe that it is enough to simply replace shock absorbers without touching the springs. However, in the case of the model Octavia A5 The resource of springs is often lower than the life of shock absorbers, and their joint replacement is the most rational solution for restoring factory performance.
Why is the rear suspension on the Octavia A5 sagging?
The main reason for the subsidence of the rear axle on the car Skoda Octavia The first generation of facelift (A5) is metal fatigue in springs. With active operation, frequent transportation of goods or trips on bad roads, spiral springs lose their elasticity faster than it is laid down in design standards.
An additional factor accelerating wear is corrosion. In winter, aggressive reagents used by utilities penetrate the curls of the spring, causing point destruction of the metal. This leads to the fact that spring bursts or irreversibly deformed, losing the design rigidity.
Often owners Octavia 1.6 notice the problem only when the car begins to lean strongly in corners or "break through" the suspension on the bumps. It is important to understand that the simmered spring changes the angle of inclination of the shock absorber, which can lead to its rapid failure due to work in abnormal mode.
Choosing the Right Parts to Replace
When selecting components for suspension repair, it is critically important to take into account the type of body and engine volume. For Skoda Octavia A5 With a 1.6-liter engine, springs are often installed with a marking that is different from versions with diesel engines or more powerful gasoline units, since the mass distribution is different.
There are two main types of springs on the market: standard (OEM) and reinforced. Standard parts from manufacturers like KYB, Lemforder Or original Czech spare parts are suitable for everyday driving. Enhanced options are often chosen by owners who regularly carry passengers or cargo in the trunk.
- π Original VW/Skoda springs: maximum geometry accuracy, but high price and risk of counterfeiting.
- π§ Analogues from brands Febi Bilstein and Sachs: excellent value for money, proven reliability.
- π‘οΈ Reinforced springs: suitable for heavy operating conditions, but can make the suspension stroke more rigid.
It is important to check the part code before buying, as even visually identical springs can have different heights and stiffness. An error in the selection will cause one side of the car to sit below the other, which is dangerous for traffic safety.
β οΈ Never install springs from different models of cars or different generations of Octavia, even if they appear identical. The difference in height can be only a few millimeters, but this is enough to disrupt the operation of the transverse stability stabilizer.

Preparation for work and necessary tools
Replacing rear springs with Octavia A5 A process that requires a certain amount of physical strength and specialized equipment. You will definitely need jacks (better two), car stands and a hydraulic spring remover. Working without a filmmaker is extremely dangerous and can lead to injuries.
Also prepare a set of keys and heads, including a rattle and extension cords. The lower mounting of the shock absorber often requires an 18 or 21 mm head, and the upper mounting requires a 15 mm key. Donβt forget WD-40 or similar penetrating lubricant for threaded joints.
- π¨ Hydraulic spring removable (required for safe compression).
- π§ A set of heads and keys (from 10 to 24 mm).
- π’οΈ Lubricant for rusty bolts.
- 𧀠Safety glasses and gloves.
Before the start of work, the car should be installed on a flat solid surface. If you plan to change the springs on both sides, it is better to remove both wheels at once so that you can access both sides of the suspension without unnecessary jack permutations.
Step-by-step instructions for replacing springs
Start by lifting the rear of the car on the jack and installing it on safety stands. Remove the rear wheels. Inspect the lower mount of the shock absorber: the bolt connecting the shock absorber with the swivel fist can be severely sour, so treat it with lubrication in advance.
Unscrew the bottom bolt of the shock absorber mount. After that, it is necessary to unscrew two nuts of the upper anchorage of the shock absorber in the luggage compartment. Remove the plastic cap, unscrew the nuts and carefully remove the shock absorber rod down. It is important to hold the shock absorber so that it does not fall.
β οΈ Warning: When removing the old shock absorber, make sure that the spring is not clamped under load, otherwise it may sharply straighten. Use the removable to compress the spring before removing the shock absorber.
Now you can remove the old spring. Look at the top and bottom of the slabs. If they crack or lose shape, they also need to be replaced, otherwise the new spring will work incorrectly and can make extraneous sounds.

Features of assembly and installation of new parts
Installation of new springs requires maximum accuracy. Before you put the spring on the shock absorber, make sure that its turns coincide with the grooves on the supports. This will ensure the correct position of the spring and prevent it from moving.
Use the removable to compress the spring until its length allows you to freely put it on the shock absorber and fix the lower mount. Do not squeeze the spring stronger than necessary, so as not to damage its structure or tool.
- β Check the matching marks on the spring and body (if any).
- β Make sure that the upper support sits exactly on the shock absorber rod.
- β Tighten all bolts with the recommended force using a dynamometer key.
After installing both springs, lower the car to the ground and rock it up and down several times so that the suspension takes its working position. Only after that, you can finally tighten the lower bolts of the fastening of shock absorbers, since in suspended condition they can be twisted.
What to do if the spring is stuck?
If the spring is attached to the support, do not hit it with a hammer. Use the mounting shovel and warm up the contact place with a building hairdryer. Sometimes treatment with penetrating lubricant helps 10-15 minutes before dismantling.
Diagnostics and verification of performance
After replacing the springs, it is critical to check the collapse-convergence of the rear axle. Changing the height of the rear suspension inevitably affects the angles of installation of the wheels. Even if you only replace one spring, the suspension geometry will change, which can lead to the car being sideways or rapid tire wear.
Visually check if the body height is the same on both sides. The car should be horizontal, without distortion. Scroll the wheels with your hands and listen to whether there are knocks or creaks that may indicate improper installation of supports or shock absorbers.
The first 100-200 kilometers after the spring replacement, try to avoid sharp accelerations, braking and movement on irregularities at high speed. This will give the suspension details time to "grain" and will allow you to identify possible errors during assembly.
Proper installation of springs and subsequent adjustment of the fall-down - a guarantee that new parts will last a long time, and the car will be driven predictably and safely.
Repair cost and completion time
Self-replacement of the back springs by Skoda Octavia A5 It saves a lot of money, but it takes time and a tool. If you decide to contact the service, note that the work of replacing the suspension is usually evaluated separately for each side.
The table below gives an estimate of the prices for parts and work that will help you plan your repair budget:
| Name of service/spare part | Approximate price (RUB) | Note |
|---|---|---|
| The back spring (original) | 3 500 - 5 000 | One-piece price |
| Back spring (analogue) | 1 800 - 3 000 | For example, Lemforder, KYB |
| Replacement work (one side) | 1 500 - 2 500 | Includes dismantling and installation |
| Rear axle deflection | 2 000 - 3 000 | Mandatory procedure |
Replacing springs with a pair is mandatory to maintain the symmetry of the suspensionEven if one of them still looks whole, as the metal resource is the same.
When buying springs in the online store, always check the possibility of a return. Sometimes the supplier may miss the marking and you will have to change the part without putting it on the car.
Frequently asked questions from Skoda Octavia owners
Do shock absorbers and springs need to be replaced?
Yes, it is recommended to change them with a set. If the shock absorbers are old, the new spring can quickly βkillβ them due to changes in loads and the course of compression.
Can I put reinforced springs on a car with a 1.6 engine?
You can, but it will make the back suspension stiffer. Reinforced springs have a larger pitch and wire diameter, which can worsen comfort on poor roads.
How long does it take to replace a single spring?
On average, an experienced master replaces one rear spring takes 40-60 minutes. In garage conditions with breaks on rusty bolts, it can take 2-3 hours.
What happens if you donβt do a wheel alignment after replacement?
The car can lead to the side, and the rear tires will begin to wear unevenly, especially on the inner or outer edge.
