Cars of the generation Tour, despite their considerable age, remain one of the most reliable and popular in the secondary market. However, the suspension of these machines, especially the rear axle, is experiencing tremendous loads, especially if you are operating a car. Skoda Octavia Tour in the conditions of Russian roads. Rear multi-link suspension or simple beam (depending on the configuration) require constant monitoring of the condition.
Exactly rear shock absorbers take the brunt of the irregularities of the asphalt, pits and joints. Their premature wear not only worsens the comfort of driving, but can also lead to emergency situations, as the geometry of the tires' grip on the road changes. In this article, we will discuss all the nuances of choosing, diagnosing and replacing these critical nodes.
Design features of the Octavia Tour rear suspension
To understand how to properly maintain the back, you need to understand the device. In most versions Octavia Tour with front-wheel drive installed beam twisting, which is simple and reliable. However, on all-wheel drive versions or powerful turbocharged modifications, a multi-link suspension is often found, requiring a more thorough approach to maintenance.
Main task shock absorber strut — dampen body vibrations after hitting an obstacle. If the shock absorber loses its properties, the spring begins to unhinderedly compress and decompress, causing the body to rock. This is especially noticeable when driving through speed bumps or potholes.
The shock body on these models is often corroded by chemicals, which can cause the rod to seize. It is important to check regularly rear pillars for mechanical damage and oil leaks. Ignoring even slight sweating can lead to complete failure of the unit in a matter of kilometers.
⚠️ Attention: If you notice that the car rolls heavily when cornering or “jumps” on small bumps, this is a direct signal that the rear shock absorbers need to be replaced.
Symptoms of wear and troubleshooting
Determine what shock absorbers have become unusable, it is possible not only in appearance, but also in the behavior of the car on the road. One of the most obvious signs is extraneous sounds. A creaking, knocking or thud when driving over bumps often indicates destruction of the internal structure of the shock absorber or wear of the upper supports.
It is also worth paying attention to the condition of the tires. If the shock absorber does not dampen vibrations, the wheel constantly bounces off the road, which leads to uneven tread wear. You may notice "spotty" wear on the tires that cannot be corrected even after a wheel alignment.
A visual inspection is a mandatory procedure with every oil change or tire fitting. You need to check for oil leaks on the strut housing. A little fogging is acceptable, but if oil drips or coats the bottom of the rack, shock absorber needs replacement. In addition, check the integrity of the boot and bump stop.
- 🔍 Rocking test: press on the corner of the body and release sharply - the car should return to its original position without unnecessary vibrations.
- 🔍 Inspection of the boots: the presence of cracks or tears leads to rapid wear of the rod and dirt getting inside.
- 🔍 Checking the fasteners: make sure that the fastening bolts and nuts are free of corrosion and have not become loose.
Choosing suitable spare parts: original or analogue?
Spare parts market for Skoda Octavia Tour is oversaturated with proposals, and it is easy for a beginner to get confused. The original is a guarantee of quality, but its price is often 2-3 times higher than good analogues. Manufacturers of original parts often produce them themselves for the VAG concern, so choosing first-tier brands (KYB, Bilstein, Sachs) is a reasonable compromise.
When choosing rear shock absorbers It is important to consider driving style and operating conditions. If you prefer a quiet ride, hydraulic shock absorbers with a soft setting are suitable. For those who like to ride aggressively or carry heavy loads, it is better to consider gas-filled struts, which provide a more rigid connection to the road.
You should not save on this unit by buying cheap Chinese analogues. Their service life can be only 10-15 thousand kilometers, after which they will need to be replaced again. High quality shock absorber from a trusted brand will last from 60 to 100 thousand kilometers, ensuring safety and comfort.
- Original (VAG)
- Bilstein
- KYB
- Sachs
- Koni

Step-by-step instructions for self-replacement
Replacing rear shock absorbers with Octavia Tour - the task is doable for one person with a minimum set of tools and an overpass or pit. The process begins by lifting the car and removing the wheels. Be sure to secure the front wheels with wheel chocks.
First you need to loosen the shock absorber rod nut without unscrewing it completely. Then the lower bolts securing the shock absorber to the beam or lever are unscrewed. Be prepared for the fact that the bolts may become stuck, so treat them with penetrating lubricant in advance. After this, carefully remove the old shock absorber.
Before installing a new rack, be sure to transfer the original boot and bumper to it if they arrived in good condition. If they are worn out, it is highly recommended to replace them with a set. The new shock absorber must be unlocked before installation (if it is gas), following the manufacturer's instructions.
☑️ Preparing for replacement
Installation is carried out in reverse order. It is important to observe the tightening torque of all bolts. The top rod nut is only tightened after the vehicle is lowered to the ground and the suspension is loaded with the weight of the vehicle. This will prevent rapid wear of the bushings.
⚠️ Caution: Never tighten the shock rod nut while the suspension is in the air. This will lead to distortion of the bushing and its rapid destruction.
What to do with springs?
If the spring shows signs of corrosion or cracks, it should also be replaced. Often the spring is also replaced along with the shock absorber, as it can weaken over time.
After replacement, be sure to check the wheel alignment angle. Any work on the suspension can throw off the wheel alignment, which will lead to uneven tire wear. Stop by the stand and adjust the parameters. This will take a little time, but will save you money on new tires in the future.
Common maintenance mistakes and how to avoid them
Many owners Skoda Octavia Tour make the mistake of changing shock absorbers one at a time. This is strictly forbidden. The wear of components always occurs synchronously, and if one shock absorber is dead, the second is most likely in critical condition. Change them strictly in pairs on the same axis.
Another common mistake is using an impact tool to tighten suspension bolts. This may damage threads or deform metal parts. Always use a torque wrench to final tighten fasteners to the recommended torque values.
Sometimes owners try to “repair” old shock absorbers by changing their oil. This is a temporary solution and does not restore original damping characteristics. Modern technology for the production of shock absorbers does not imply their disassembly and repair in artisanal conditions.
Before purchasing new shock absorbers, measure the length of the old unit in the compressed and extended state to ensure compatibility of the selected model.
Durability and operating conditions
The service life of the rear shock absorbers directly depends on the quality of the roads and driving style. On roads with poor surfaces, the life of shock absorbers can be halved. If you often drive on unpaved roads or with a fully loaded vehicle, the diagnostic frequency should be increased.
Winter operation using reagents requires special attention to the state of corrosion protection. Regular washing of the car's underbody and suspension will help extend the life of not only shock absorbers, but also all elements of the rear axle. Clean your suspension from dirt after every winter ride.
Don't forget about proper use. Avoid sudden shocks to the suspension at high speeds. A smooth ride is not only comfort, but also the key to long service life of all components of the car. Regular inspection and timely replacement of worn elements is the key to safety.
Rear shock absorbers should always be replaced in pairs and the upper rod nut should only be tightened after the vehicle has been lowered to the ground.
FAQ: Frequently asked questions
Is it possible to change shock absorbers one at a time?
No, this is unacceptable. Different degrees of damping on the left and right sides will lead to instability of the car and accelerated wear of other suspension components. Always change in pairs.
Do I need to do a wheel alignment after replacement?
Yes, after replacing shock absorbers, especially if the levers or mounts were affected, the suspension geometry may change. It is recommended to visit the stand to check and adjust the wheel alignment angles.
How to distinguish gas from oil in a shock absorber?
Gas-filled shock absorbers typically have "Gas" or "GAS" written on the body and feel stiffer when compressed by hand. Oil shock absorbers are softer and are often labeled "Oil".
How long does it take to replace rear shock absorbers?
If you have a hole and good tools, replacing two rear shock absorbers with an experienced technician takes about 1-1.5 hours. For a beginner, this process may take 2-3 hours.
What to do if the stem nut does not unscrew?
Use a special hex wrench to hold the rod. Apply a penetrating lubricant and give it time to work. If the nut is stuck, gently heat it with a hair dryer, avoiding heating the rod itself.
