Many car owners ignore the problem until the car starts to stick at the bottom or extraneous knocks appear in the rear. Suspension The car requires timely attention, since the serviceability of the springs directly affects the safety of operation. In this article, we will analyze in detail why problems arise, how to choose the right replacement, and what nuances should be taken into account when replacing yourself.
Why does the rear suspension sag on the Octavia Tour?
The main reason for subsidence is natural fatigue wear of the metal. Springs operate under constant cyclic loads: compression when driving over uneven surfaces and expansion when driving on a flat surface. Over time, the elastic properties of steel are lost, and the spring ceases to return to its original position with the required force. On Skoda Octavia Tour This is particularly evident due to the rear beam design and weight distribution.
The second important factor is aggressive operation or constant overload. If you often carry heavy loads in the trunk or passengers in the back seat, the service life of the springs is reduced significantly. Reinforced springs can help in such a situation, but standard parts quickly fail when the permissible load is exceeded. It is also worth considering the condition of the road surface, since frequent impacts on the wheels accelerate the process of metal fatigue.
The influence of corrosion should not be discounted. In winter, when roads are covered with reagents, the metal of the springs is exposed to aggressive influence. The appearance of rust on the coils reduces their cross-section and strength. Protective coating It wears off over time, and the process of destruction proceeds faster, especially in places where the coils come into contact with each other.
β οΈ Attention: Ignoring the subsidence of one of the springs can lead to misalignment of the body, which will cause uneven tire wear and problems with the geometry of the rear axle. The condition of the suspension must be checked regularly, especially after the winter season.
Symptoms and diagnostics
You can determine if the springs are faulty visually, but there are also indirect signs that will indicate the need for replacement. The most obvious symptom is a change in vehicle clearance. If the rear of the car sits significantly lower than the front, or one side has sunk more than the other, this is a sure sign that the spring has lost its elasticity or has broken.
When driving, you may hear noises such as creaking or knocking noises from the rear suspension. This may mean that the spring has moved out of place or has collapsed, and the metal coils have begun to beat against each other. Shock absorbers can also make sounds, but if the problem is in the spring, then the nature of the knock will be more dull and resonant.
Another sign is a change in the car's behavior when cornering. A sagging suspension changes the kinematics of the rear beam, which can cause the car to become less stable or begin to βfloatβ at high speeds. If you notice that the steering wheel has become heavier or vibrations have appeared, it is worth checking suspension elements in a specialized service.
- π Visual inspection: check the integrity of the turns and the absence of deep corrosion.
- π Measuring ground clearance: measure the distance from the wheel to the arch from different sides and compare the results.
- π Sway test: press on the rear bumper and release; If the body rocks more than twice, the spring or shock absorber is worn out.

Choosing new springs: original or analogues
When choosing new springs, the owner is faced with a dilemma: buy original spare parts or turn to proven analogues. Original springs from Skoda guarantee perfect compliance with factory specifications, but their price is often inflated. Additionally, original parts may be supplied in different batches, sometimes resulting in slight differences in height, although this is rare.
There are high-quality analogues on the market from leading suspension manufacturers. Brands like KYB, Koni, SWAG or LemfΓΆrder offer products that are not inferior to the original in terms of steel quality and knurling technology. Sometimes analogues are even superior to factory parts, since manufacturers can use more modern alloys to increase service life.
It is important to consider that for different modifications Octavia Tour (with a 1.6, 1.8 engine or with gas equipment) springs of different stiffness may be required. LPG adds weight to the trunk, so stronger springs are often recommended for such cars. Incorrect selection can lead to the car being too rigid or, conversely, sagging faster.
Is it worth installing reinforced springs?
Reinforced springs have a larger rod diameter and a greater number of turns. They are better suited for cars with LPG or frequent cargo transportation, but can make the suspension stiffer when the car is empty.
Tools and preparation for replacement
Replacing rear springs with Skoda Octavia Tour - a task of average complexity that can be completed independently with a minimum set of tools and car working skills. You will need a jack, reliable stands for the body, a set of sockets and wrenches, and a spring puller. Without a puller, it is almost impossible to compress the spring and remove it without the risk of injury.
Before starting work, it is necessary to prepare the workplace. The vehicle must be parked on a level surface and the rear wheels must be blocked. Remove the rear wheels to gain access to the suspension components. Inspect shock absorber supports and anthers; if they are worn out, it is also recommended to replace them along with the springs so as not to disassemble the unit again.
It is important to remember safety precautions. The spring is in a compressed state and has enormous energy. Any mistake when operating the puller can result in serious injury. Use only serviceable tools and do not neglect safety glasses and gloves. Hand protection must be mandatory, since the metal may have sharp burrs.
βοΈ Preparing to replace springs
Step-by-step instructions for replacing springs
The replacement process begins with fixing the car on stands. Remove the wheel and unscrew the lower nut securing the shock absorber to the lever. Next, you need to disconnect the stabilizer bar link if it interferes with access. After this, carefully lower the shock absorber down to release the spring from the lower seat.
Now start compressing the spring. Place the puller on the spring coils on opposite sides and begin to tighten the screws evenly. Spring compression should be uniform so as not to warp the tool and damage the coils. Compress until the spring releases the top seat.
After compression, remove the old spring and replace it with a new one. Make sure the new spring is in the correct orientation: the bottom coil usually has a different shape or color marking. Install the spring into the seats, making sure it fits snugly and is not dislodged. Carefully loosen the puller, making sure that the spring does not fly out.
Tightening order:1. Make sure the spring is seated in the grooves.
2. Slowly loosen the puller.
3. Raise the shock absorber and secure the lower nut.
4. Tighten the upper support bearing.
Assembly is carried out in reverse order. Don't forget to install new boots and compression buffers if they come with the springs. After installing the springs, you need to check the operation of the suspension by pressing the body several times so that the springs βsit downβ.
Before starting work, mark the position of the spring on the shock absorber with a marker so that when installing a new part, maintain the same orientation, if so provided by the design.
β οΈ Attention: After replacing the springs, be sure to visit the wheel alignment stand. Changing the height of the rear suspension will inevitably change the wheel alignment, which will lead to accelerated tire wear and poor handling.

Nuances of operation and maintenance
After installing new springs, it is important to follow some operating rules to extend their service life. Avoid sudden shocks to the suspension on large bumps in the first weeks after replacement. Run-in new suspension elements will help them better βget used toβ the seats and shock absorbers.
Regularly clean the springs from dirt and reagents. Washing your suspension every time you wash your car will help prevent corrosion. If you notice that the spring has begun to rust, apply a special preservative or anti-corrosion coating to it. Corrosion protection is a simple way to increase the service life of a part several times.
Monitor the condition of other suspension elements. Worn stabilizer bushings or bushings can create additional stress on the springs, accelerating their wear. An integrated approach to chassis maintenance will ensure comfort and safety for many years. Timely repairs minor faults save money in the long run.
Replacing the rear springs on a Skoda Octavia Tour is not only a restoration of ground clearance, but also an important step towards safety, since a working suspension is critical for the carβs stability on the road.
Common mistakes when replacing yourself
One of the most common mistakes is using the wrong tools to compress the spring. Cheap pullers can burst under stress, causing injury. Always check that the tool is in good condition before starting work. The tool must be designed for the maximum diameter and spring stiffness of your vehicle.
Another mistake is ignoring the condition of the support bearings. If you change the springs and leave the old βdeadβ bearings, then after a while a creaking and knocking noise will appear, and you will have to disassemble the suspension again. Complex replacement of all worn-out elements saves time and effort in the future.
Incorrect spring installation is also common. If the spring does not fit into the grooves or is skewed, it may jump out during movement, which is dangerous for others. Carefully examine the seat design and ensure proper installation before lowering the vehicle. Installation control must be thorough.
FAQ: Answers to frequently asked questions
Is it possible to change only one spring?
It is recommended to replace springs in pairs, even if one of them still looks intact. The difference in stiffness and height between the old and new spring will lead to body distortion and uneven suspension operation. This can cause handling problems and tire wear.
Do shock absorbers and springs need to be replaced?
Preferably. If the shock absorbers are worn out, they will not dampen the spring vibrations properly. This will cause the new springs to wear out quickly and reduce comfort. Check the condition of the shock absorbers: if there is a leak or knocking, replace them with a set.
How long does it take to replace rear springs?
For an experienced technician, replacing both rear springs takes about 1-1.5 hours. For a beginner, this process can take 3-4 hours, including preparing tools and studying instructions. Take your time to avoid mistakes.
Does replacing springs affect fuel consumption?
Not significant. If you installed standard springs, the flow rate will remain the same. If you installed reinforced springs, they can make the suspension stiffer, but this has virtually no effect on fuel consumption unless you change your driving style.
What to do if after replacement the car sank again?
If the subsidence occurred quickly, perhaps poor-quality springs were installed or the stiffness was incorrectly selected. Also check the condition of shock absorbers and other suspension elements. Perhaps the problem is not only with the springs.
