Vehicle operation Skoda Octavia in Russian conditions inevitably leads to suspension wear, and rear shock absorbers are often the first element requiring attention. They are responsible for the traction of the wheels with the road when cornering and for the comfort of passengers when driving over uneven surfaces. Many owners mistakenly believe that the rear axle is loaded less than the front, but overloading the trunk or frequent driving on broken roads quickly disables them.
Timely diagnosis and replacement shock absorber struts avoid costly chassis repairs in the future. Ignoring extraneous knocks or the car pulling to the side when braking can lead to loss of control at high speeds. In this article we will look at how to choose the right spare part, which brands offer the best price-quality ratio, and how to replace it yourself.
Particular attention should be paid to the design features of different generations of the model. Octavia. While the A5 and A6 versions use classic spring struts, the model Octavia A7 with independent rear suspension (Multilink) requires a more complex approach to dismantling and installation. Understanding these nuances will save you time and money in the service.
Symptoms of malfunction and diagnostics of the rear suspension
Determine that the shock absorbers are Skoda Octavia have exhausted their service life, this can be determined by a number of characteristic symptoms that appear already at an early stage of wear. The first and most obvious signal is the appearance of dull knocks when driving over small bumps or speed bumps. The sound often resembles metal hitting metal and is heard from the trunk.
The second important criterion is the behavior of the car in motion. If you notice that the rear of the car is swaying strongly after hitting an obstacle or when braking sharply, it means hydraulic fluid inside the shock absorber has lost its properties. You may also experience uneven wear on the rear tires, especially as "spotting" on the tread.
Visual signs should not be ignored either. Inspect the bottom of the shock absorber for signs of oil leakage. Even slight drops on the body indicate that the oil seal is worn out, and shock absorber strut is on the verge of failure. In addition, check the condition of the anthers and bump stops - their destruction often precedes the breakdown of the mechanism itself.
β οΈ Attention: Long-term driving on faulty shock absorbers leads to accelerated wear of silent blocks, levers and crosspieces of the driveshaft. Repairing the suspension assembly will cost many times more than replacing two struts in a timely manner.
For accurate diagnostics, it is recommended to use the stand in a specialized service center where vibration test. However, you can do a preliminary test yourself by shaking the rear of the car with force with your hands. If, after the impact has stopped, the body continues to oscillate more than once or twice, the shock absorbers must be replaced.
- The appearance of extraneous knocks and creaks in the rear suspension.
- Excessive body sway when braking or turning.
- Visual traces of oil on the shock absorber body.
- Uneven tire wear on the inside or outside.
Types of shock absorbers and design features
There are three main types of shock absorbers on the auto parts market: gas, oil and gas-oil. For Skoda Octavia The manufacturer most often recommends gas-oil struts, which provide a balance between comfort and controllability. They are less sensitive to temperature changes and react faster to road irregularities.
Oil shock absorbers are considered softer and more comfortable, but are prone to βairingβ during aggressive driving, which leads to loss of efficiency. Gas struts are characterized by high rigidity and excellent road grip, but reduce passenger comfort on poor asphalt. The choice depends on your driving style and operating conditions.
Particular attention should be paid to the type of fastening. On some modifications Octavia (especially with a 1.2 TSI or 1.4 TSI engine) the rear suspension may have differences in the design of the arms and mounts. It is important to know exactly the VIN code of your car before purchasing to avoid selection errors. Rear axle design may vary even within the same model year.
- Oil (comfort)
- Gas (sport)
- Gas-oil (golden mean)
- Original from the factory
Some owners seek to install stronger springs along with shock absorbers for increased load-carrying capacity. This is an acceptable solution, but requires recalculation of the rigidity of the entire system, otherwise suspension will become too rigid and lose its damping properties. Always comply with the manufacturer's recommendations for such changes.
- Gas: high rigidity, excellent handling, low comfort.
- Oil-based: smooth running, rapid overheating during active driving.
- Gas-oil: universal option, recommended by the factory.
Review of manufacturers and selection of quality spare parts
The choice of brand plays a decisive role in the longevity of the suspension. Original from Skoda (often produced by a company KYB or Sachs) is a standard of quality, but costs much more than its analogues. When purchasing an original spare part, you receive guaranteed compliance with all factory parameters of rigidity and travel.
Among analogue manufacturers, the following stand out: KYB (Excel-G series), Sachs, Monroe and Boge. These brands offer products that often surpass the original in terms of resources at an adequate price. For example, shock absorbers KYB are considered tougher and more durable, which is perfect for Russian roads.
Budget options from little-known Chinese or Turkish brands are strictly not recommended. Savings on hydraulics and seals often leads to the fact that new struts fail after 10-15 thousand kilometers. You end up spending money again on labor and parts, overpaying in the long run.
| Brand | Type | Approximate price | Service life (km) | Recommendation |
|---|---|---|---|---|
| Skoda Original | Gas-oil | High | 80 000+ | Ideal for a relaxing ride |
| KYB (Excel-G) | Gas-oil | Average | 60 000 - 80 000 | Best price/quality ratio |
| Sachs | Gas-oil | Medium/High | 70 000 - 90 000 | Excellent comfort and resource |
| Monroe | Gas-oil | Average | 50 000 - 70 000 | Good choice for the city |
β οΈ Attention: Never buy shock absorbers without a protective boot and bump stop. Their absence will lead to dirt quickly getting on the rod and destroying the oil seal, even if the shock absorber itself is of high quality.
When choosing, pay attention to the equipment. Often only the shock absorbers themselves are sold, and the components (boot, bump stop, nut) must be purchased separately. Make sure that the kit contains all the necessary hardware for installation on your model Octavia.
What to do if the kit does not include anther?
If the manufacturer does not include a boot in the kit, be sure to purchase it separately. Installation without a boot is unacceptable, as dirt and water will quickly damage the rod. Itβs better to overpay for a set than to change the stand after six months.
Instructions for replacing rear shock absorbers
The process of replacing rear shock absorbers with Skoda Octavia does not require specific equipment, but requires accuracy and consistency of actions. Before starting work, you need to prepare the car: place it on a flat surface, turn on the handbrake and place wheel chocks under the front wheels.
First you need to dismantle the wheel and unscrew the nut securing the shock absorber rod in the trunk. This will require opening the trunk trim to gain access to the top of the pillar. Use appropriately sized wrenches to avoid stripping the threads on the stem.
- Prepare a jack, stands and a set of tools (keys 13, 15, 18, 21).
- Remove the rear wheel and secure the car on a secure stand.
- Unscrew the shock absorber rod nut in the luggage compartment.
- Unscrew the lower shock absorber mounting to the arm.
- Remove the old shock absorber and install the new one.
An important nuance: when dismantling the old shock absorber, the spring is in a compressed state. Be extremely careful to avoid injury. If the spring shows signs of corrosion or deformation, it is strongly recommended to replace it as well, since spring stiffness could have changed.
βοΈ Preparing to replace shock absorbers
Installing a new shock absorber is done in the reverse order. Please note that the rod nut should only be tightened after the vehicle is lowered onto the wheels. This is necessary to ensure that the rubber bushings do not twist when tightening, which will lead to their rapid destruction.
To make tightening the rod nut easier, use a special hex wrench, which often comes with shock absorbers. Do not try to turn the stem with an open-end wrench, as this may damage its surface.
Common replacement mistakes and how to avoid them
Many car enthusiasts make the mistake of changing shock absorbers on only one side. This is categorically false, since difference in hardness between the old and new strut will result in uneven weight distribution and unstable vehicle behavior. Always change shock absorbers in pairs, even if one of them still seems to be working.
Another common mistake is using a thread lubricant that is not intended for suspension. Regular lubricant may wash away with water or attract dirt, making subsequent disassembly difficult. Use special anti-corrosion compounds or graphite thread lubricant.
Do not tighten the mounting bolts until the vehicle is on the ground. Rubber-metal hinges (silent blocks) should work in a natural position, and not in a twisted position. Ignoring this rule will lead to rapid failure of the suspension arms and the appearance of knocking noises.
β οΈ Caution: Do not use a pneumatic impact wrench to tighten the bolts securing the shock absorber to the control arm. High torque can damage the threads or deform the aluminum parts of the lever.
Sometimes during assembly there are difficulties with aligning the holes. Do not use excessive force or hit the shock absorber rod with a hammer. Try rocking the car or lever to line up the holes. The shock absorber rod should not rotate when the nut is tightened., use the key to fix it.
Replacing shock absorbers should always be done in pairs while simultaneously checking the condition of the springs, silent blocks and support bearings. Skimping on one part can lead to suspension imbalance.
Maintenance and life extension
Even high-quality shock absorbers require regular care and attention. Periodically inspect them for leaks and damage to the anthers. The cleanliness of the suspension also plays a role: wash off reagents and dirt from the lower part of the body to avoid corrosion of the mounts.
Follow vehicle loading regulations. Skoda Octavia has certain maximum weight restrictions that cannot be exceeded. Constantly driving with the trunk overloaded causes the springs to sag and the shock absorbers to work at the limit of their capabilities.
When operating in winter, avoid sudden impacts on the suspension in deep snow or ice. Fragile parts may crack under impact. If you notice that your car is handling worse on a snowy road, check the condition of the suspension first.
- Wash the pendant regularly after winter, removing reagents.
- Avoid overloading the trunk beyond the permissible limit.
- Check the tightness of all fasteners after 5000 km.
Frequently asked questions (FAQ)
Is it possible to change shock absorbers on only one side?
No, this is absolutely not recommended. The difference in the characteristics of the old and new strut will lead to an imbalance in the suspension, poor handling and accelerated wear of other elements. Always replace shock absorbers in pairs.
Is it necessary to do a wheel alignment after replacing shock absorbers?
When replacing rear shock absorbers with Skoda Octavia The wheel alignment angles usually do not change, since camber and toe adjustment at the rear is not provided (factory setting). However, if levers or bushings were affected during the replacement, checking the suspension geometry will be useful.
What mileage is considered normal for rear shock absorbers?
The average resource of rear shock absorbers ranges from 60,000 to 100,000 km, depending on operating conditions, road surface quality and driving style. You should focus on signs of malfunction, and not just mileage.
Is it possible to install gas shock absorbers instead of oil ones?
Yes, installing gas or gas-oil shock absorbers instead of oil ones is possible and even recommended to improve handling. The main thing is to make sure that the models you choose meet the specifications of your car and are not too harsh for your needs.
Why is the new shock absorber knocking?
A knock on a new shock absorber is most often caused by improper tightening of the fasteners (especially while the car is not on wheels) or the absence/damage of the boot and bump stop. It is also possible that the kit was missing the required bushings or that the stem nut was overtightened.
