Car rear suspension Škoda Superb The second generation (type 3T) is experiencing tremendous loads, especially if we are talking about versions with all-wheel drive or powerful turbo engines. Over time, the springs lose their elastic properties, which leads to subsidence of the body, violation of the angles of the wheel installation and the appearance of unpleasant knocks when passing irregularities. Ignoring these signs can lead to more serious breakdowns of shock absorbers and body elements.
The process of replacing springs on this model has its own characteristics, differing from similar works on the model. Volkswagen Passat or Octavia. The design of the rear beam and the location of the fasteners require careful approach and the use of special tools. In this article, we will discuss in detail how to independently perform this work, what parts to choose and what to fear during dismantling.
Symptoms of wear and diagnostics of suspension
To determine the need to replace springs can be visually and by the behavior of the car on the road. The first alarming signal is a change in clearance: the back Škoda Superb It starts to sink even if the car is empty. This is especially noticeable when parking on a flat surface or when compared to a new car.
The second sign is the appearance of characteristic knocks and creaks in the back of the body when passing by lying policemen or pits. Often owners mistakenly change shock absorbers, unaware that the problem lies in the metal spring, which is tired and has lost stiffness. In such cases, the shock absorber operates in an abnormal mode, which leads to its rapid failure.
It is also worth paying attention to the uneven wear of tires. If the spring has sank on one side, the geometry of the suspension is broken, and the wheel begins to "clap". This leads to rapid erasure of the tread along the edge of the tire and the appearance of steering beating at high speeds. Regular inspection of the suspension on the lift allows you to identify these problems at an early stage.
⚠️ Note: If you notice that the car is heavily tilted in corners or the rear axle “falls down” when braking sharply, the operation of such vehicles is dangerous. Violation of the suspension kinematics can lead to loss of controllability on a slippery road.
- Visual subsidence of the back of the body even without load.
- The appearance of knocks when passing irregularities, even with new shock absorbers.
- Uneven wear of rear tires (wear on the inner or outer edge).
- Increased sensitivity of steering to road irregularities.
Selection of quality spare parts and components
When choosing springs for Škoda Superb 2 It is important to understand that original parts are often produced under the brand. VAGbut are produced by large suppliers such as Koni, Lemförder or Boge. Buying the original in a box with the Skoda logo is a guarantee of quality, but often it is the same product, only with a different label and a higher price.
An alternative could be proven brands specializing in suspension. Companies Sachs and Monroe offer excellent analogs, which often have improved durability characteristics compared to stock parts. However, when choosing analogues, be sure to check the catalog numbers, since springs of different stiffness can be put on the same model depending on the engine and type of drive.
Pay special attention to the condition of support cups and insulators. Often when replacing springs, owners save on these little things, but rubber bushes over time bluff and collapse, which leads to the appearance of creaks and the transfer of vibration to the body. It is better to immediately replace the entire set: the spring, upper support and anther of the shock absorber.

Necessary tools and preparation
To perform the work, you will need an impressive set of tools, since access to the fastener on the rear axle Superb limited. The basic set includes a set of heads from 10 to 24 mm, rattle collars, an extension cord and powerful gates for unscrewing sour bolts. It is necessary to have a jack and two reliable insurance stands (goats).
The most critical element will be the spring remover. Without it, it is almost impossible to compress the spring manually and extremely dangerous. It is recommended to use professional screw removers, which allow you to control the compression process evenly from both sides. The use of artisanal techniques, such as belt or chain screeds, is strongly discouraged due to the risk of injury.
Also prepare a penetrating lubricant such as WD-40 or Loctite 7800 for processing of threaded joints. Bolts of the rear beam fastening are often clamped dead, and without pre-treatment they can simply be torn off. Do not forget about the mounting blade for uncrushing the Bushings and a slash screwdriver for dismantling the plastic underwings.
- A set of heads and keys (including a dynamometer key).
- The sleeves of the sleeves are (required!).
- Hydraulic jack and safety stands.
- Penetrating lubricant and metal brush.
⚠️ Warning: Never attempt to dismantle the spring without the use of special detachers. The compressed spring has a huge energy, and when the instrument accidentally jumps off, it can fly out with the force of a bullet, causing serious injuries.
☑️ Preparing for replacement
Step-by-step instructions for dismantling and installation
Start by lifting the car on the lift or using a jack. Remove the rear wheels and remove the plastic underwings to access the top of the shock absorber. Unscrew the bolt of the mounting of the shock absorber rod in the underhood space or through the hatch in the trunk, depending on the configuration.
Next, it is necessary to disconnect the rack of the lateral stability stabilizer from the shock absorber. Then unscrew the bottom bolt of the shock absorber attachment to the swivel fist or beam. Carefully lowering the shock absorber, you will release the spring, but it will still be under tension.
Install spring removers on the upper and lower parts of the turns, tightening them evenly until the spring is freed from the seats. Remove the old spring. Before installing a new part, be sure to clean the boarding cups of dirt and rust, if necessary, apply an anti-corrosion coating.
Features of installation of springs
When installing a new spring, make sure that its end accurately falls into the groove of the lower support cup. If the spring is installed with a skew, it can pop out at the first load, which will lead to sagging of the wheel and accident.
Put the knot back together. First, put a new spring, then install a shock absorber, tighten the bottom bolt and the stabilizer rack. This will ensure the correct tension of the rubber metal hinges.
After assembly, do not forget to check the angles of the wheel installation. Any work with suspension elements that affect geometry requires subsequent tuning of the collapse-descend. Ignoring this step will result in rapid tire wear and "thrust" the car to the side.
Tightening of the bolts of the shock absorber and levers should be made only when the suspension is loaded (wheel on the ground), otherwise the rubber bands of the Bushings will be twisted and quickly destroyed.
Nuances of work with electronics and systems
On some versions Škoda Superb 2equipped with air suspension or adaptive chassis system DCCThe process of replacing springs has its own characteristics. In such cases, it is necessary to turn off the battery before starting work to avoid short circuits and errors in the suspension control unit.
If the car is equipped with a body level control system, after replacing the springs, adaptation may be required. The control unit may incorrectly consider the height of the body if the spring has a different stiffness or height. In some cases, it is enough to travel several kilometers for the system to calibrate itself, but sometimes you need to connect a diagnostic scanner and conduct a procedure. Basic Settings.
Pay attention to body position sensors that can be integrated into suspension levers. When dismantling the springs, try not to damage the wires and connectors of these sensors. Damage to the wiring can lead to errors on the dashboard and disabling the stabilization system.
If the dashboard lights up suspension error after replacing the springs, try to reset the errors with a diagnostic scanner. If the error is returned, you may need to adapt the height of the body through the service menu.
Common mistakes and how to avoid them
One of the most common mistakes is to replace only one spring. This causes one side of the car to become stiffer or taller than the other, which upsets the suspension balance and leads to unstable behavior on the road. Always change the springs in pairs, even if one of them looks whole.
Another mistake is using springs from another modification. For example, the installation of springs from Superb with a diesel engine on the version with a powerful gasoline engine will lead to a subsidence of the rear. Different engines have different weights, and springs are selected individually under the load. Always check the catalog number before buying.
Do not forget about the condition of the bearings. If you change the springs and the old bearing continues to creak, the work will be done in vain. When replacing the springs, it is recommended to immediately change the entire assembly of the upper support, including the bearing and rubber damper.
- Replace the springs on one side of the car.
- Use of spare parts from another modification (different engine weight).
- Savings on the replacement of upper supports and bearings.
- Incorrect tightening of suspension bolts without load.
⚠️ Warning: Never use springs with cracks or traces of corrosion, even if they look whole. Metal with microcracks can not withstand the load and break in motion, which will lead to loss of control.
FAQ: Frequently asked questions from owners
How long does it take to replace the rear springs on the ŠKODA Superb 2?
With the right tool and experience, replacing a pair of springs takes 2 to 3 hours. If you are doing this for the first time, lay down a minimum of 4-5 hours, as you will have to deal with sour bolts and study the design.
Do I need to do a wheel alignment after replacing the springs?
Yes, I will. Replacing the springs changes the geometry of the suspension and the height of the body, which directly affects the angles of installation of the wheels. Without a break-down setting, the tires will start to wear off quickly.
Can I use the Passat B6 or Octavia A5?
No, it's not recommended. Although the platforms are similar, the catalog numbers and stiffness of the springs may differ. Incorrectly selected springs will lead to disruption of the suspension and traffic safety.
What to do if the shock absorber bolt does not unscrew?
Use a powerful gate, penetrating lubricant and, if necessary, heating the bolt with a building hair dryer or burner (caution, next to plastic and rubber). If the bolt breaks down, you will have to drill it, which will greatly complicate repairs.
Can I install springs with increased clearance?
Technically possible, but this will require the selection of appropriate shock absorbers and possibly extenders of the levers. Installation of only the spring without changing other elements of the suspension will lead to a rapid failure of shock absorbers due to excess of their working stroke.
