Rear suspension on cars Škoda Octavia A5 is subjected to significant loads, especially if the machine is used to transport goods or drives on bad roads. Over time rear springs lose their elastic properties, which leads to sagging of the body and disruption of the geometry of the chassis. Ignoring this problem can cause rapid wear of the shock absorbers and poor handling.
The process of replacing suspension elements on a model Octavia A5 has its own technical nuances, which are important to consider when making repairs yourself. Incorrect installation or the use of low-quality spare parts often causes repeated failure of components in the shortest possible time. In this article we will analyze all stages of work, from diagnostics to final assembly.
Signs of wear and diagnostics of spring suspension
Determine what rear springs require replacement, based on a number of characteristic symptoms that appear even before the car clearly subsides. Most often, the driver notices the appearance of extraneous knocks or creaks in the rear of the body when driving over uneven surfaces. These sounds indicate that the spring has lost its elasticity or cracks have formed in it.
Visual inspection is also an important diagnostic step. If you notice that the car sits lower on one side or in the rear overall, this is a sure sign of metal fatigue. In addition, you should check the condition of the shock absorber boots, since their damage is often accompanied by deformation of the springs. Skoda Octavia A5 has a fairly reliable suspension, but the service life of the springs directly depends on the quality of the roads and the load.
Sometimes the problem is disguised as a faulty shock absorbers. If, when pressing on the rear bumper, the body oscillates more than twice before stopping, this indicates a damping problem. However, if the spring sag, it stops working correctly in conjunction with the shock absorber, creating additional load on it. Suspension diagnostics must be comprehensive to avoid false conclusions.
⚠️ Attention: Driving with sagging springs changes the angle of the rear headlights, which can blind oncoming drivers and lead to a fine on the road.
Selection of spare parts: original or analogues
When choosing new suspension elements for Škoda Octavia A5 Car owners are often faced with a dilemma: buy original parts from VAG or choose high-quality analogues. Original springs are usually marked with a colored dot to indicate stiffness. This is critical to maintaining factory handling characteristics.
There are various brands on the market that produce springs for VAG cars. Among the most reliable manufacturers are KYB, Koni, Sachs and TRW. These companies supply products to assembly lines, so their quality is often not inferior to the original, and the cost may be lower. However, it is worth checking the package carefully, since the kit should contain not only the springs themselves, but also the upper supports or spacers.
- 🔍 Check the markings on the packaging, it must match the VIN code of your car.
- 💰 Compare prices in several stores, but do not go for the lowest price, as this may indicate a fake.
- 📦 Make sure that the springs are supplied in secure packaging to protect them from deformation during transportation.
Some drivers try to save money by installing springs from other models or using remanufactured parts. This approach is strictly not recommended, as the geometry and rigidity may not be suitable for your body. Hardness mismatch will lead to accelerated wear of rubber suspension elements and disruption of kinematics.
Necessary tools and preparation
Before starting replacement work rear springs It is necessary to prepare the appropriate tools and provide a safe place for repairs. You will need jacks, car stands, a set of sockets and wrenches, and a special tool for compressing the springs. Without the last tool, the work will be extremely dangerous and almost impossible.
To remove springs from Octavia A5 Often it is necessary to remove the rear wheels and unscrew the lower shock absorber bolts. Sometimes it is necessary to remove mudguards or other protection elements to gain access to the fasteners. Make sure the vehicle is on a level surface and secured with the handbrake and wheel chocks.
- 🛠️ Set of socket heads: 13, 15, 18, 21 mm (depending on the year of manufacture).
- ⚙️ Spring ties: an essential element for safe dismantling.
- 🔧 A prybar and a crowbar for pressing out the suspension elements if necessary.
- 💨 WD-40 or similar penetrating lubricant for loose bolts.
If you are not experienced with working with spring ties, it is highly recommended that you leave this step to a professional. Incorrect compression can cause the spring to be ejected from the unit with tremendous force, causing serious injury or property damage. Safety precautions should be in first place during any manipulations with the suspension.

Step-by-step instructions for replacing springs
The replacement process begins with lifting the rear of the car and placing it on secure stands. Remove the wheel and unscrew the lower shock absorber mounting bolt. After this, you must carefully lower the shock absorber down to release the spring. Be careful: the spring is compressed and may jump out.
To safely remove the spring, use special ties. Place them on the coils of the spring on opposite sides and begin to gradually tighten them until the spring loses tension. Only after this can you unscrew the upper support and remove the old part. On Škoda Octavia A5 the top support is often bolted to the body through a plastic sleeve.
☑️ Preparing to replace springs
Installing a new spring occurs in the reverse order. It is important to make sure that the spring is seated correctly. The lower cup of the body has a specific shape, and the spring must lie flat. After installing the ties, they must be slowly released, making sure that the spring does not warp.
⚠️ Attention: When assembling, be sure to replace the upper rubber shock absorber mounts, as the old ones often crack and lose their elasticity.
Features of working with the rear stabilizer
If your vehicle's rear stabilizer bar interferes with spring removal, it may need to be temporarily disconnected. Unscrew the stabilizer bushing and lower it down. Be sure to tighten the stabilizer bar bolts to the recommended torque after installing the new springs.
After installing the spring, you need to return the shock absorber to its place and tighten the lower bolt. It is necessary to tighten the shock absorber mounting bolt until it stops only when the car is standing on its wheels and the weight of the body is pressing on the suspension. In a suspended state, the rubber bushing can twist, which will lead to its rapid destruction.
Repeat all steps for the second side. Even if the spring looks intact on one side, it is recommended to replace them in pairs to ensure the same stiffness and body height. Suspension symmetry critical for stable vehicle behavior on the road.
The lower bolt of the shock absorber should only be tightened under load when the car is standing on its wheels, so as not to damage the rubber bushing.
Frequent errors and technical nuances
One of the most common mistakes when replacing springs is not installing the spring correctly in the cup. On Octavia A5 the lower coil of the spring has a special protrusion that should fit into a groove on the body. If the spring is placed in the wrong place, it may become distorted, which will lead to knocking and rapid failure.
Another mistake is ignoring the condition of the silent blocks of the levers and stabilizer bushings. Often, when replacing springs, car owners do not pay attention to these elements, although they may be worn out. This reduces the overall comfort and efficiency of the repair. Integrated approach Suspension repairs can save time and money in the future.
| element | Symptoms of wear | Recommendation |
|---|---|---|
| Springs | Body sagging, knocking | Replacement by pair |
| Shock absorbers | Oil leak, runout | Replacement when springs are worn out |
| Silent blocks | Backlash, creaks | Replacement if there are cracks |
| Stabilizer bushings | Knocking on bumps | Check and replacement |
Some mechanics try to adjust the springs if they seem too stiff or high by using spacers or cutting the coils. This is a gross violation of operating rules, which changes the characteristics of the suspension and can lead to an accident. Never cut spring coils, this violates their structure and security.
It is also important to check the wheel alignment geometry after replacing the springs. Changing the body height affects the wheel alignment angles, which can lead to rapid tire wear and poor handling. Wheel alignment after such work is a mandatory procedure.
Before purchasing new springs, measure the height of the rear body and write down the readings - this will help you assess the degree of sagging and choose the right replacement option.

Average life of rear springs Škoda Octavia A5 ranges from 100 to 150 thousand kilometers, but it greatly depends on operating conditions. Driving on bad roads, frequent overloads and an aggressive driving style significantly reduce this resource. Regular suspension inspections can help identify problems at an early stage.
For preventive purposes, it is recommended to periodically clean the springs from dirt and salt, which can cause corrosion. Corrosion significantly reduces the strength of the metal and can lead to sudden failure of the spring. Use special lubricants for rubber elements to extend their service life.
- 🧼 Clean the suspension from dirt after driving on winter roads.
- 🔍 Perform a visual inspection of the springs at every oil change.
- 🚫 Avoid overloading the vehicle beyond its permissible weight.
If you notice the slightest signs of wear and tear, do not delay repairs. Timely replacement rear springs will save your shock absorbers and ensure safety on the road. Ignoring the problem can lead to more expensive repairs in the future.
