Vehicle operation Skoda Octavia Tour is often associated with the need for routine maintenance, especially when the mileage approaches 150 thousand kilometers. One of the most common suspension problems at this age is sagging or broken springs. Ignoring this malfunction leads to wheel alignment problems, accelerated tire wear and, critically, a decrease in controllability at high speeds.
The process of replacing front springs on this model has its own specific features that differ from more modern generations. You will need not only a set of standard tools, but also an understanding of how to properly remove the stabilizer link and disconnect the brake hose without damaging its mounting. Incorrect actions can cause the spring to fly out with enormous force, causing injury to the operator.
Causes of failure and fault diagnosis
The main reason for spring failure is constant cyclic load and exposure to an aggressive environment. In harsh winter conditions, when roads are coated with reagents, the metal undergoes intense corrosion. Even with a factory coating, microcracks in the paint over time lead to rust, which thins the rod and reduces its elasticity.
The second factor is the physical wear of the metal, which manifests itself in loss of elasticity. Over time, the spring “gets tired” and stops returning to its original position after going through irregularities. This leads to the fact that the car begins to “float” on the track, and the shock absorbers begin to work under maximum loads, overheating and failing faster than expected.
The need for replacement can be determined by several visual and behavioral signs. If you notice that the front of the car is sagging, especially after loading the trunk, this is a sure sign. Another characteristic feature is the appearance of knocking noises when passing speed bumps, which intensify on uneven surfaces.
It is important to carry out a thorough visual inspection. Inspect the spring for visible cracks or chipped paint where rusty metal is visible. Pay attention to the condition of the support bearings, as they often fail at the same time as the springs.

Selection of original and analog spare parts
Spare parts market for Skoda Octavia Tour offers a huge selection of options, from original parts to budget analogues. Original spring from VAG guaranteed to meet all factory parameters of stiffness and height, but costs significantly more. This is the optimal choice for those who plan to use the car for a long time and want to maintain the factory suspension characteristics.
Analogues from trusted manufacturers such as KYB, Sachs or Lemförder, often offer the best value for money. These brands have their own manufacturing techniques and can even outlast the original in certain conditions. However, when choosing an analogue, you must carefully check the catalog numbers, since for different years of manufacture and body types the springs may differ in stiffness.
There is also a category of so-called “hardened” springs. They have an increased cross-section of the rod and are designed for vehicles with increased loads or for those who often drive with a full load. Installing these springs unnecessarily on a standard vehicle can make the suspension too stiff, reducing ride comfort.
When purchasing, be sure to check the integrity of the packaging and the presence of a protective coating. The spring must be coated with high-quality paint or epoxy. Also, do not forget to purchase new support bearings and shock absorber boots, as their reuse can lead to rapid failure of the new spring.
- ✅ Original parts (VAG) - maximum reliability and price
- 🏆 Premium analogues (Sachs, KYB) - balance of price and quality
- 🛠️ Budget options - require careful quality control
- 🔧 Components (supports, boots) - mandatory replacement during repairs
⚠️ Caution: Never install springs with visible signs of rust or deformed coils, even if they appear new. This can lead to sudden destruction of the part during movement.

Necessary tools and preparation for work
To carry out the work of replacing springs, you will need an impressive set of tools. The main element is the spring puller, which allows you to safely compress the spring before unscrewing the upper mount. Without this tool, work is impossible and extremely dangerous, since the spring is under strong tension.
You will also need the standard tools: a set of sockets (including an 18 socket for the shock rod nut), a ratchet, a wrench, a torque wrench and a pry bar. Don't forget to use a penetrating lubricant like WD-40 or similar, as the suspension bolts on older cars tend to stick.
For ease of work, it is advisable to have a lift or inspection hole, as well as a jack and reliable supports. If you are working outdoors, make sure the surface is hard and level. The suspension and shock assembly must be removed, so provide a place to mount the strut on a workbench or stable surface.
Before starting work, be sure to disconnect the negative terminal of the battery to avoid accidental short circuits when working with ABS sensor wiring or wire fasteners.
☑️ Preparing to replace springs
Step-by-step instructions for dismantling the rack
The process begins by lifting the car and removing the front wheel. After this, you need to unscrew the bolts securing the lower arm to the steering knuckle. This often requires a lot of force, so use a wrench extension and penetrating lubricant beforehand.
Next you need to disconnect the steering knuckle from the steering knuckle. To do this, use a puller or carefully beat it with a hammer, working on the hinge body and not on the threads. After this, unscrew the bolts securing the shock absorber strut to the steering knuckle.
The rack is now free from the bottom. From above you need to unscrew the three nuts securing the shock absorber support to the body. Be careful as the spring is under load. Carefully remove the stand assembly from the arch and place it on the workbench.
Use a spring puller on the workbench. Place the puller arms on opposite coils of the spring and compress it evenly until the load on the support bearing disappears. Only after this can you unscrew the upper nut of the shock absorber rod.
⚠️ Attention: When compressing the spring with a puller, make sure that the jaws are securely fixed and will not come off. Never stand in the area where a spring or puller could fly out.
What to do if the stem nut is spinning?
If the rod nut rotates with the shock absorber, use a 6 or 7 mm hex inserted into the rod from the top, or a special tool to hold the rod.
Installation of new springs and assembly
After removing the old spring, carefully inspect the shock absorber. If it leaks or has play, it is strongly recommended to replace it along with the spring. Install a new boot and bumper on the clean rod, then put on a new spring.
Before installing the new spring, make sure it is in the correct orientation. The lower turn must lie in the corresponding recess of the support. Install a new support bearing and upper support. Tighten the rod nut, but do not tighten it all the way until the spring is completely relaxed.
Gently open the spring remover, controlling the process, so that the spring falls into place. Make sure that the upper and lower coils of the spring are in the correct seats. Now you can finally tighten the rod nut with a torque wrench to the torque specified by the manufacturer.
Place the strut back into the arch, screw it to the steering knuckle and lower control arm. Don't forget to reconnect the brake hose and ABS sensor wiring if they were disconnected. Tighten all mounting bolts to the required torque.
Before tightening the lower strut-to-arm bolts, lower the vehicle until the wheels touch the ground so that the suspension is in the working position.
Features of adjustment and final checks
After replacing the springs with Skoda Octavia Tour It is imperative to visit the wheel alignment stand. Changing the suspension geometry even by a few millimeters can lead to uneven tire wear and poor directional stability. The technician must adjust the wheel alignment angles taking into account the new spring height.
Check the operation of the brake system and the absence of brake fluid leaks after disconnecting the hoses. Spin the wheel and make sure there is no contact with the suspension elements. Take it for a test drive, paying attention to the absence of knocks and smooth operation.
It is important to check the operation of the shock absorbers. If you only replaced the springs, but the old shock absorbers are worn out, they may not be able to cope with the new load. In this case, the suspension may become too stiff or, conversely, “wobbly”.
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Rod nut tightening torque | 60 + 90° | Nm + angle |
| Tightening torque of the strut bolts to the knuckle | 140 | Nm |
| Lower arm bolt tightening torque | 100 | Nm |
| Tightening torque of the tie rod nut | 35 | Nm |
| Wheel moment | 120 | Nm |
⚠️ Attention: Replacing only one spring is unacceptable This will cause the suspension to skew and cause uneven wear on the tires and controls.
Correct installation of the spring requires precise adherence to the tightening torque of all fasteners and mandatory subsequent wheel alignment adjustment.
Common replacement errors and their consequences
One of the most common mistakes is incorrect spring installation. If the coils have not taken their seats, the suspension may “shoot” at the first load, which will lead to an accident. Always visually check the spring position before lowering the vehicle.
Another mistake is saving on related parts. Reusing old journal bearings or boots often results in the new spring not working properly and the shock absorber failing within a short time. This is a saving that ends up costing more.
It is also worth noting the error associated with tightening the bolts by weight. If you tighten the lower bolts securing the strut to the arm while the car is hanging on a jack, enormous stress will arise in the threads when lowered to the ground, which can lead to stripping of the threads or deformation of the arm.

FAQ: Answers to frequently asked questions
Do I need to replace both springs at once?
Yes, replacing springs must be done in pairs on the same axis. This will ensure equal suspension stiffness on the left and right, which is critical for the safety and handling of the vehicle.
Is it possible to replace springs without a puller?
No, this is extremely dangerous. The spring is under enormous pressure. Attempting to remove the stem nut without compressing the spring may cause the spring to fly out and cause serious injury.
How long does it take to replace springs?
For an experienced technician, replacing the two front springs takes about 2-3 hours. For a beginner with no experience working with suspension, this process can take up to 4-5 hours.
Do I need to do a wheel alignment after replacement?
Absolutely a must. Replacing springs changes the suspension geometry, and without adjusting the wheel alignment angles, you risk quickly “killing” the new tires.
What springs are best to install to improve comfort?
To improve comfort, it is recommended to choose original springs or analogues marked “Comfort”. It is not recommended to install lowered or shortened springs without replacing shock absorbers.
