Crossover owners Skoda Kodiaq Often faced with suspension issues, especially when the mileage is approaching the mark of 80-100 thousand kilometers. One of the most loaded elements that provide comfort and handling are rubber metal hinges. They extinguish the vibrations transmitted from the road, and keep the geometry of the suspension within the specified limits.
Silent blocks on this car are subjected to enormous loads due to the large weight of the body and the combination of rigidity and comfort characteristic of the Czech brand. Ignoring the signs of wear and tear of these parts can lead to accelerated failure of neighboring units such as levers, shock absorbers and even steering elements. Proper diagnosis and timely replacement are the key to safety and predictable behavior of the car on the road.
Design and types of silent blocks in the Kodiaq suspension
Suspension Skoda Kodiaq has a complex architecture, where levers with two silent blocks are used in the front part, and a multi-link circuit with many attachment points is used in the rear part. Each of these nodes has its own specific design. In the front suspension, hinges are most often found, where a rubber bushing is pressed into an outer metal cage and an inner bushing, which can be either solid or with a hole for a bolt.
The rear axle of the crossover is equipped with more massive elements, as they take on the weight of passengers and luggage, and also work during active acceleration and braking. Some modifications have reinforced silent blocks with additional stiffeners or special gaskets. It is important to understand that not all silent blocks are the same: their rigidity is selected by engineers for a specific type of drive and engine power.
There are two main types of execution that can be found in spare parts catalogs: classic rubber-metal and polyurethane. Standard parts from the manufacturer are made of special wear-resistant rubber that is resistant to temperature changes. Polyurethane counterparts, although offering stiffer suspension response, often suffer from rapid degradation when exposed to harsh chemicals used in winter.
- ๐ง Front lower control arms usually have two silent blocks of different diameters and stiffness.
- ๐ง The rear trailing arms are equipped with large joints that can withstand torque.
- ๐ง The anti-roll bar uses mini bushings where it attaches to the arms.
โ ๏ธ Attention: Never try to replace the silent block without a special puller, as trying to knock it out with a hammer can deform the aluminum lever, which will lead to its failure and the need for complete replacement.
Symptoms of wear and troubleshooting
Determine that silent blocks Skoda Kodiaq require replacement, based on a number of characteristic signs that manifest themselves in the behavior of the car. The most obvious symptom is a knocking or creaking sound in the suspension that occurs when driving over bumps, potholes or speed bumps. The sound may be a dull thud or a sharp metallic grinding sound, depending on the degree of destruction of the rubber.
The second important sign is deterioration in controllability. The car may begin to โfloatโ on the road, especially when driving in a straight line at high speed. The steering wheel may vibrate, and during emergency braking the car may pull to the side. This occurs due to a violation of the suspension geometry when the arms begin to move relative to their seats.
A visual inspection often reveals a problem before it becomes audible. If you see that the rubber part of the hinge has deep cracks, cuts, or has completely peeled off from the metal casing, then replacement is inevitable. Sometimes the rubber simply falls out of the body, leaving the bolt dangling in the air.

Replacement technology and necessary tools
Replacing silent blocks is a labor-intensive process that requires special equipment and experience. Unlike simply replacing shock absorbers, it is necessary to use a hydraulic press or special pullers to press in old parts and press in new parts. Working with the suspension Skoda Kodiaq requires precision, as aluminum parts of the levers are easily damaged.
Before starting work, you must lift the car on a lift and remove the wheels. Then the bolts securing the arms to the subframe and to the steering knuckle are unscrewed. It is important to remember or mark the position of the shims if present. After removing the lever from the car, the old silent block is removed using a press, and a new one is installed in its place.
It is extremely important to observe the tightening torque of the bolts. Tightening should only be done after the vehicle is lowered to the ground to ensure that the rubber part of the hinge is not twisted under the weight of the vehicle. This will ensure the correct service life of the part and driving comfort. Ignoring this rule will lead to rapid destruction of new tires.
โ๏ธ Preparing to replace silent blocks
Tightening torque of the lever bolts to the subframe: 120 Nm + 90 degreesโ ๏ธ Attention: Do not use silicone or oil-based lubricant when pressing rubber-to-metal joints, as this may cause the rubber to swell and subsequently fail.
Is it possible to change only the silent blocks and not the entire lever?
Yes, technically this is possible, but it requires abs and time. Car service centers often offer to replace the entire lever assembly, as this is faster and guarantees that there will be no problems with the seats if they were damaged when dismantling the old hinge.
Selection of spare parts: original or analogues?
In the spare parts market for Skoda Kodiaq a wide range of options available: from original parts VAG to budget analogues and specialized brands. Original silent blocks usually have a catalog number starting with the prefix 5Q0 or 3Q0, and provide the comfort and service life declared by the factory. They undergo strict quality control and meet all parameters.
Analogues from well-known manufacturers such as Lemfรถrder, TRW, Febi Bilstein or Sasic, are often not inferior to the original in quality, and sometimes even surpass it due to improved rubber compounds. These brands are suppliers to the assembly line, so their products are fully compatible with the car. However, when choosing analogues, you should carefully check certificates and reviews.
Budget options from China or unknown manufacturers can save money when purchasing, but their resource is often 2-3 times less. The rubber in such parts can harden after just a year of use or, conversely, become too soft and tear quickly. Saving on silent blocks may result in more expensive suspension repairs in the future.
| Brand | Type | Approximate resource (km) | Features |
|---|---|---|---|
| Skoda Original | Original | 100 000+ | The perfect balance of comfort and durability |
| Lemfรถrder | Premium analogue | 120 000+ | High quality rubber, often original supplier |
| TRW | Premium analogue | 90 000+ | Good geometry, reliable steel cage |
| Budget brands | Economy | 30 000 - 50 000 | Low price, but the risk of rapid failure |
Original silent blocks or analogues from Lemfรถrder/TRW will provide maximum service life and maintain the factory characteristics of the Kodiaq suspension.
Influence of operating conditions and care
The service life of silent blocks directly depends on the conditions in which the car is operated. In an urban environment with frequent stops and starts, the load on the suspension is less than when driving on the highway at high speeds. However, winter operation using reagents and salts significantly shortens the life of rubber elements, causing them to corrode and crack.
Regular cleaning of the suspension and treatment with protective compounds can extend the life of the hinges. It is important to monitor the integrity of the rubber boots, if they are provided for in the design. A damaged boot allows dirt and water to reach the metal parts, leading to jamming or rapid wear. Using harsh chemicals to clean your suspension in winter can speed up the deterioration of the rubber.
Driving off-road or in deep potholes creates shock loads that can instantly rupture the rubber or dislodge the metal bushing. Owners Skoda Kodiaqwho often travel outside the city, it is recommended to carry out more thorough diagnostics of the suspension every 30 thousand kilometers. This will allow you to identify hidden defects before they lead to an emergency.
- ๐ง๏ธ Regular washing of the underbody and suspension in winter.
- ๐ง๏ธ Inspect rubber elements for cracks and cuts after traveling on bad roads.
- ๐ง๏ธ Avoiding sudden impacts when driving through deep potholes at high speed.
โ ๏ธ Attention: If you notice that the silent block has begun to creak, do not put off replacing it for too long. A creaking sign means that the lubricant inside the joint has dried out or the rubber has lost its elasticity, and further use will lead to its complete destruction.
Frequently asked questions from Skoda Kodiaq owners
Many car owners ask questions about the specifics of servicing the suspension of this crossover. Below are answers to the most popular of them, based on operating and repair experience.
Do I need to change silent blocks in pairs?
Yes, it is strongly recommended to change silent blocks on one axis in pairs. If one joint is worn out, the second one is most likely in the same condition, since they work under the same conditions. Replacing only one part can lead to an imbalance in the suspension and accelerated wear of the new part.
Is it possible to drive with a cracked silent block?
It is possible for a short time, but it is not safe. A crack in the rubber can quickly expand, causing the joint to completely come off. In this case, the lever may be pulled out of its seat, causing loss of control of the vehicle. It is better to replace the part immediately.
Do I need to do a wheel alignment after replacement?
Absolutely a must. Any intervention in the suspension geometry, especially replacing levers or silent blocks, changes the wheel alignment angles. Without wheel alignment adjustments, the tires will wear unevenly and the vehicle will pull to the side.
How long does it take to replace silent blocks?
Replacing silent blocks on one axis usually takes from 2 to 4 hours, depending on the complexity of the design and the availability of tools. If the entire lever assembly is replaced, the process may go faster, but requires more time to purchase spare parts.
Before replacing silent blocks, be sure to check the condition of the shock absorber boots and stabilizer silent blocks, since their wear often occurs in parallel and can be detected during disassembly.
