Car suspension Skoda Octavia A5 is famous for its reliability, but even it is subject to natural wear and tear, especially when used on Russian roads. One of the most vulnerable points is the rubber-metal hinge, which dampens vibrations and provides an elastic connection of the levers to the body. When factory elements become unusable, many owners are faced with a dilemma: replace them with original parts or immediately switch to reinforced analogues.
Installation reinforced silent blocks - This is not just replacing a worn part, but a way to significantly extend the service life of the entire front or rear suspension. Such elements are made of more wear-resistant rubber or polyurethane, which allows them to withstand heavy loads without loss of elasticity. However, incorrect selection or installation can lead to accelerated destruction of the levers or the appearance of extraneous knocks, so the issue must be approached with technical literacy.
In this article we will look at how reinforced products differ from standard ones, which brands have proven themselves best on the platform Octavia A5, and how to properly carry out the replacement procedure on your own. You will learn what nuances to pay attention to when purchasing and why saving on this unit may cost more in the future.
Why do standard silent blocks quickly fail?
Factory silent blocks on the model Skoda Octavia A5 Made of soft rubber, which provides maximum riding comfort. This design perfectly absorbs minor road irregularities, creating the effect of “hovering” above the surface, but has a significant drawback in the form of low resistance to aggressive environments and mechanical overloads.
In our climate, rubber quickly hardens from frost, cracks under the influence of reagents, and simply wears out due to constant cycles of compression and expansion. The rear levers are especially affected, where the load is distributed unevenly due to the design features of the multi-link suspension. Rubber destruction inside the hinge leads to the metal bushing starting to dangle, causing play and wheel wobble.
Ignoring the problem at an early stage often leads to the destruction of not only the element itself, but also the seats on the lever or suspension bracket. Restoring the suspension geometry in this case requires an expensive replacement of the entire lever assembly, although timely replacement of the bushings could save the lever. The service life of standard rubber elements on the Octavia A5 rarely exceeds 60-80 thousand kilometers during active use.
⚠️ Attention! If you notice a characteristic knocking sound in the front or rear suspension when driving over speed bumps, do not delay diagnosis. A destroyed silent block can lead to loss of controllability at a critical moment.
Materials of manufacture: rubber vs polyurethane
When choosing reinforced parts, you will encounter two main types of materials: quality oil-resistant rubber and polyurethane. Each of them has its own advantages and disadvantages, which directly affect the behavior of the car and the comfort of the driver. Understanding the differences will help you make informed choices based on your driving style.
Polyurethane has significantly greater rigidity and abrasion resistance than conventional rubber. It is practically not afraid of reagents and temperature changes, maintaining its properties even in severe frosts. However, the increased rigidity of the material transfers more vibrations from the road to the body, which can reduce comfort when driving on poor asphalt.
Modern reinforced rubber silent blocks from top brands are often superior to polyurethane in terms of a combination of characteristics. They are made from special compounds that do not tan in the cold and have an increased service life. It is important to note that polyurethane bushings require more thorough lubrication during installation, otherwise squeaks and scuffing on the metal cage may occur.
- 💧 Polyurethane is best suited for sport riding and trail use where precision handling is important.
- 🛣️ High-quality rubber maintains the comfort of city use and better dampens high-frequency vibrations.
- ❄️ Both materials are superior to standard rubber in terms of resistance to reagents and temperature changes.
Many owners Octavia A5 choose a compromise option: reinforced rubber for the rear suspension and polyurethane for the front, where the loads are higher. This approach allows you to maintain controllability without completely sacrificing comfort when driving on rough city roads. Always check for quality certificates and reviews of a specific manufacturer before purchasing.
TOP manufacturers of reinforced elements for Octavia A5

Preparatory stage and necessary tools
Before you begin the replacement, you need to make sure you have all the necessary tools and lifting equipment. Working with the suspension requires precision and physical strength, so you cannot do without specialized tools. An attempt to squeeze out an old silent block with a sledgehammer or a vice without the support of a lever can lead to its deformation.
You will need hydraulic press or a specialized puller for silent blocks. You will also need a wheel wrench, a jack, reliable stands and a set of sockets. To work with polyurethane, you additionally need to prepare a silicone-based lubricant that does not destroy the material. A viewing hole or overpass is required.
☑️ Preparing to replace silent blocks
It is important to check the condition of the lever itself before installing new elements. If there are cracks, corrosion or severe deformation in the mounting hole, installing even the most expensive reinforced silent blocks will not produce results. The metal of the lever must be perfectly smooth and clean.
⚠️ Attention! Never try to press in a new silent block without first cleaning and lubricating the seat. This can lead to bushing misalignment and rapid failure.
Step-by-step instructions for replacement and pressing
The replacement process begins by removing the suspension arm from the vehicle. To do this, you need to loosen the mounting bolts to the body and to the hub, and then carefully remove the lever. Pay attention to the position of the bolts and washers so that during assembly you do not mix them up, which can change the wheel alignment.
The most difficult stage is pressing out the old and pressing in the new element. Use hydraulic press, distributing the force evenly across the cage. The pressure must be applied strictly along the axis of the bushing. If you use a puller, be careful not to damage the bolt threads. For polyurethane, be sure to apply a layer of silicone lubricant to the outer surface.
After installing the new element, check its position: it should be flush or with a slight protrusion, according to the manufacturer's specifications. Avoid distortion. Place the lever in place, tighten the bolts to a preliminary torque, but the final tightening should be done only after the car is lowered to the ground and the wheels are loaded with the weight of the car.
What to do if the old silent block does not give in?
If the old element is stuck or deformed, do not try to knock it out by force. Try using a penetrating lubricant (WD-40 or equivalent), give it time to work, and then gently heat the metal cage with a heat gun. In extreme cases, it may be necessary to cut out the rubber with a grinder, but be extremely careful not to damage the metal of the lever.
The final stage includes checking the tightness of all bolts and installing protective covers, if provided by the design. If you have changed the silent blocks on the rear suspension, pay attention to the condition of the anti-roll bar bushings, as they often wear out in conjunction with the levers.
The final tightening of the suspension arm bolts must be done strictly under load (when the wheels are on the ground), otherwise the silent block may quickly collapse due to twisting of the rubber.
Features of operation after installation
After replacing reinforced silent blocks, the behavior of the car may change. If you installed polyurethane, you will notice sharper steering response and reduced body roll when cornering. However, vibrations from small irregularities may become a little more noticeable. This is a normal reaction to increasing suspension stiffness.
For the first 500-1000 kilometers, it is recommended to avoid extreme loads: deep holes, sudden starts and braking. Rubber or polyurethane needs time to “grind in” to the metal clips and take its working position. It is also important to undergo the procedure wheel alignment after replacing any suspension elements.
- 🚗 Avoid driving through deep holes at high speed during the first weeks of operation.
- 🔧 Check the tightness of the bolts after 1000 km, as they may “sit” a little.
- ⚙️ Inspect the suspension regularly for cracks or traces of grease.
Reinforced elements require more careful attention to diagnostics. If you feel a new knock or squeak, do not delay your visit to the service station. Early detection of the problem will allow you to avoid costly repairs to other suspension components. Correctly installed reinforced silent blocks can last 2-3 times longer than standard ones.
Periodically clean the silent blocks from dirt and road salt with a soft brush to prevent premature aging of the material from the chemical effects of reagents.
Common mistakes during selection and installation
Many car owners make the mistake of trying to save on the cost of work or parts. Installing low-quality analogues often leads to the problem returning after just a few thousand kilometers. Another common mistake is not properly tightening the bolts before lowering the vehicle to the ground.
Another common problem is using the wrong lubricant. Some drivers use lithol or graphite lubricant for polyurethane, which is strictly prohibited. These compounds can corrode the material, causing it to swell and break down. Use only special silicone lubricants.
Ignoring the condition of the lever when replacing silent blocks also leads to failure. If the seat has runout or deformation, the new element will not be able to ensure the tightness and rigidity of the connection. Always check the lever geometry before pressing in new bushings.
⚠️ Attention! Do not use a hammer or sledgehammer to press directly onto the metal frame of the silent block. This will upset the balance and can lead to microcracks in the metal.
Compliance with installation technology and the choice of proven brands is the key to long and trouble-free operation of your suspension Skoda Octavia A5. Reinforced silent blocks are an investment in safety and comfort, which pays off in the absence of constant service visits.
Questions and answers
Do I need to change all the silent blocks at once or can I do it one at a time?
It is recommended to change silent blocks on one axis (both sides) at the same time. If one of them is worn out, then the second is most likely in a similar condition. This will ensure uniform behavior of the suspension and prevent distortions.
Is it possible to install polyurethane silent blocks on the rear suspension of the Octavia A5?
Yes, you can, but keep in mind that the rear multi-link suspension is very sensitive to the stiffness of the elements. Polyurethane can make the ride too harsh and cause squeaks. It is better to choose reinforced tires for the rear axle if you do not plan active sports driving.
How long does it take to replace silent blocks?
If you have professional equipment (press) and experience, replacing silent blocks on one axis takes from 1.5 to 3 hours. In a garage without a press, the time can double due to the difficulty of pressing out old elements.
Does replacing silent blocks affect wheel alignment?
Yes, replacing silent blocks, especially the front ones, can change the suspension geometry. After installing new elements, it is necessary to undergo a wheel alignment procedure to correctly adjust the wheel alignment angles.
