Car rear suspension Skoda Octavia A5 plays a critical role in ensuring stable handling and ride comfort. Structurally, it is made according to a multi-link design, which allows you to effectively dampen vibrations from road unevenness and maintain the trajectory when turning. However, any mechanical connections wear out over time, and it is the levers that often become the weak link in this system.
Car owners Skoda Octavia A5 With a mileage of more than 100,000 kilometers, they often face the need to replace suspension elements. Ignoring signs of wear can lead to unstable vehicle performance on the track, accelerated tire wear, and even damage to more expensive transmission components. Timely diagnostics and competent repairs allow you to avoid costly emergency situations.
Rear suspension design and arrangement
Rear suspension model Octavia A5 is a complex system consisting of several levers, a stabilizer of transverse stability and shock racks. The main load falls on the longitudinal and transverse levers that connect the hub of the wheel with the car body. Each of these elements has its own design and purpose.
Longitudinal levers are responsible for the longitudinal positioning of the wheel and perceive braking forces. The transverse levers, in turn, keep the wheel in the correct position when cornering and when exposed to lateral loads. All connections are carried out through special Bushings and ball supports, which are consumables.
Particular attention should be paid to the material of the manufacture of levers. In most cases, they are made of steel profile, which provides high strength, but also makes them susceptible to corrosion when reagents are ingested. It is important to understand that the geometry of the suspension is determined by the position of these levers, so any deformation is unacceptable.
Symptoms and diagnostics
To determine the wear of the rear levers can be a number of characteristic symptoms that manifest themselves in the process of operation. The very first sign is the appearance of extraneous sounds in the back of the car when passing irregularities. Dry knock or a thump often indicates the destruction of the Bushings or backlash in the ball supports.
The second sure sign is uneven wear of tires. If you notice that the rubber wears faster on the inside or outside, it may indicate a violation of the wheel installation angles due to worn levers. In some cases, the car begins to โswimโ at high speeds or wag when braking.
For accurate diagnosis, it is necessary to conduct a visual inspection of the suspension on the lift. Pay special attention to the condition of rubber bushes and hinges. If the rubber is cracked, layered or completely absent, replacement is required. Luft in ball supports is also easily detected when the wheel is swaying.
Do not delay repairs when even the slightest suspicion is detected. A faulty suspension affects traffic safety, especially in emergency situations where sharp maneuverability is required. Regular inspection of suspension elements should be part of your maintenance schedule.
- ๐ Dry knocking or blows from behind when passing pits and lying police officers.
- ๐ Uneven wear of tires, especially along the inner or outer edge.
- ๐ Take the car away when braking or at high speed.
Often owners confuse the sounds of worn levers with a malfunction of shock absorbers. To avoid making a mistake, try swaying the wheel with your hands in a vertical plane. If there is a tangible backlash, the problem is precisely in the levers or their mounts, not in the racks.

Selection of spare parts: original versus analogues
In the market of auto parts there is a huge selection of options for replacing rear suspension levers. The manufacturers offer original parts from Skoda/Volkswagenand products of third-party brands. The choice depends on your budget, driving style and plans for further operation of the car.
Original levers are characterized by perfect geometry and quality of materials, but their cost is often overstated. In addition, in the original packaging, only the lever itself is often sold, and Bushings and ball supports need to be purchased separately. This can significantly increase the total cost of repairs.
Analogues from well-known manufacturers such as TRW, Lemfรถrder or SachsThey often surpass the original in terms of resource and build quality. These brands are suppliers to the conveyor, so their products fully meet factory specifications. However, it is important to avoid cheap fakes and little-known Chinese brands that could fail in a few thousand miles.
There are also ready-made sets of levers assembled with already installed bushings. This greatly simplifies the replacement process and reduces the risk of errors during installation. However, such sets are more expensive, and sometimes it is more profitable to buy a lever separately and install the bushings yourself.
| Manufacturer | Product type | Average price (RUB) | Resource (km) |
|---|---|---|---|
| Skoda (OEM) | Lever assembly | 8 000 - 12 000 | 150 000+ |
| Lemfรถrder | Lever with Bushing | 5 000 - 7 000 | 120 000 - 150 000 |
| TRW | Lever assembly | 4 500 - 6 500 | 100 000 - 120 000 |
| Meyle | Lever (improved) | 4 000 - 5 500 | 100 000+ |
โ ๏ธ Note: Do not buy levers without labeling the manufacturer on the metal. Counterfeiting often has thinner walls and poor-quality rubber, which can cause the bushing to rupture while driving.
When choosing analogues, be sure to check catalog numbers. Often the same lever has different articles for different years of release or body types (liftback, station wagon). Combi). An error in the selection of a part can lead to the fact that it simply does not stand in place or violates the geometry of the suspension.
What are reinforced levers?
Reinforced levers often have thicker walls or special inserts. They are recommended for aggressive driving or if the car is used to tow trailers. However, on a standard car, they can make the suspension too rigid.
Preparation for replacement and necessary tools
Before starting work, you need to prepare the workplace and all the necessary tools. To replace the rear levers with Skoda Octavia A5 You will need a lift or a flat surface with a viewing hole. Work on "goats" or jack is possible, but requires maximum care and compliance with safety measures.
From the tool you will definitely need: a set of end heads (including large sizes of 18, 21, 24 mm), a collar and a rattle, a dynamometer key for the correct tightening of bolts. Also, you can not do without mounting or scrap for pressing levers when installing new Bushings.
If you plan to change the Silent blocks separately from the levers, you will need a special press to squeeze them out. This is a time-consuming operation that requires a powerful tool. In most cases, it is easier and cheaper to replace the lever assembled with already installed bushings.
- ๐ ๏ธ End keys and heads (17, 18, 21, 24 mm).
- ๐จ Mounting or a large scrap for levers.
- ๐ Dynamometer key to control tightening.
- ๐งด Penetrating lubricant (WD-40 or analog) for unscrewing rusted bolts.
Before starting work, abundantly treat all threaded connections with penetrating lubricant. This is especially important for bolts attaching to the body, which are often clinging to due to dirt and reagents. Let the tool stand for 10-15 minutes so that it penetrates the thread.
โ๏ธ Preparing to replace levers
Step-by-step instructions for replacing levers
The process of replacing the rear levers begins with the removal of the wheel and providing access to the suspension nodes. After the car is raised, it is necessary to loosen the bolts of the lever attachment to the body and to the hub. Do not twist them completely at once, it is better to do this when the wheel is still on the ground so that it does not scroll.
Then we unscrew the bolt of the lever attachment to the hub. There is often a problem: the bolt can be pinched dead. In this case, use a screwdriver or gently hit the bolt head with a hammer to knock the rust. Do not put excessive effort to avoid breaking the thread.
After removing the old lever, clean the seats on the body from dirt and rust. Apply a small amount of anti-corrosion composition to the bolts before installing new parts. This will extend the life of the threaded connections.
The installation of a new lever is done in reverse order. This is necessary so that the Silent blocks are not twisted in the non-working position, which would lead to their rapid destruction.
Bolts of mounting levers to the body must be tightened only after the car is completely lowered on the wheels to avoid twisting the Bushings.
Use the dynamometer key to tighten all connections. The timing of tightening is specified in the technical documentation: usually 80-120 Nm for hub bolts and 100-150 Nm for bolts to the body. The exact values depend on the year of production and the type of engine.
If you only change the silenth blocks, the process will be more complicated. You will need to press the old bushings and press new ones. For this, use a removable or hydraulic press. Make sure that the new sleeve stands straight, without distortions.
โ ๏ธ Warning: Never tighten the bolts of the levers on weight! If you tighten them to lower the car, the Bushing will be constantly compressed, which will lead to its rupture after several thousand kilometers.
Wheel alignment after replacement
After the rear levers have been replaced Skoda Octavia A5 It is necessary to perform the procedure of disintegration-convergence. Replacing the levers changes the geometry of the suspension, and without adjusting the angles of the wheels installation, you risk uneven rubber wear and deterioration in handling.
In the rear suspension Octavia A5 The angles of collapse and convergence are regulated. On some modifications, this is done using eccentric bolts, on others - by installing adjusting washers. The master at the stand of the collapse-descend must choose the necessary parameters so that the wheel stands flat.
Ignoring this procedure can cause new levers to quickly fail. In addition, the car can behave unpredictable on the road, especially during emergency braking. Do not skimp on this procedure, it is inexpensive, but it guarantees safety.
Note that some services may offer โzeroโ settings, but itโs better to target factory settings for your specific body. If you often drive with a full load or trailer, ask the wizard to take this into account when setting the corners.
- ๐ Checking the angles of collapse and convergence is mandatory after the replacement of the levers.
- ๐ Incorrect setting leads to rapid wear of tires and suspension.
- โ๏ธ Adjustment may require the installation of additional washers or eccentrics.
Write down the parameters of the collapse-descend before the repair and after. Compare them to make sure that the master did the job qualitatively and did not make errors in the settings.
Common mistakes and expert advice
Many owners Skoda Octavia A5 They make common mistakes when replacing the levers, which lead to re-repair. One of the most common is to replace only one lever. If one is worn out, the second is likely to be close to a critical condition. It is recommended to change the levers in pairs to maintain the symmetry of the suspension.
Another mistake is using old bolts. The thread on the bolts can be damaged and the metal is tired. Always change the bolts of the levers mounting for new ones, especially if they have stretched bolts. Reuse of such bolts is unacceptable.
Do not save on the quality of lubricant for threaded joints. Use special compositions that are resistant to high temperatures and moisture. Conventional engine oil is not suitable here, as it will quickly leak out and will not protect against corrosion.
If you notice that the levers are very worn out, check also the condition of shock absorbers and springs. Often these elements fail at the same time, and the replacement of only the levers will not give the desired result in comfort and handling.
โ ๏ธ Note: If the bolts of the lever attachment do not unscrew, do not try to cut them off with a Bulgarian without body protection. Use special removers or heating to avoid damage to the paintwork and body elements.
Sometimes there is a situation when new levers do not stand in place due to deformation of the body or previous unqualified repairs. In this case, a deeper diagnosis and, possibly, adjustment of the geometry of the body or the use of transition bushings will be required.
Always change the levers in pairs and only use new mount bolts to ensure the longevity of the repair and safety of movement.
Repair cost and feasibility
The cost of replacing the rear levers Skoda Octavia A5 It is based on the price of spare parts and works. If you do it yourself, you will save on the services of the service, but spend time and effort. On average, work on the service station costs from 3000 to 6000 rubles per axle, depending on the region and the complexity of access.
If you choose original parts, the budget can be about 20,000 rubles per axle. With qualitative analogues, this amount is reduced to 10 000 - 12 000 rubles. Either way, itโs a smart investment in your carโs safety that will pay off with no issues going forward.
Compare prices in different stores and consider the cost of delivery. Sometimes it is more profitable to buy a set of levers in the assembly than individual parts. Also pay attention to the availability of a warranty for spare parts - this is an important indicator of their quality.
Do not postpone the repair until the last. The longer you drive with a worn suspension, the more likely you are to damage other nodes, such as hub bearings or shock absorbers. Timely replacement of levers is the key to a long and trouble-free operation of your car.
How often should I change the rear levers to the ล KODA Octavia A5?
The average life of the rear levers is 100,000 - 150,000 km. However, this indicator depends on operating conditions, road quality and driving style. If there are knocks or backlashes, the check should be carried out immediately.
Can I drive with a faulty suspension lever?
Yes, but only to the nearest service. Long-term operation with a damaged lever is dangerous: it can break off, which will lead to loss of control and accident. It also accelerates the wear of tires and other suspension elements.
Is it necessary to do a wheel alignment after replacing the levers?
I will. Replacing the levers changes the geometry of the suspension. Without adjusting the angles of the wheels, you will get rapid tire wear and unstable car behavior on the road.
Which is better: change the lever entirely or just the Bushing?
If the lever is not deformed, you can only replace the Bushing, but it is time consuming. It is often easier and more reliable to put the lever in the assembly, especially if it has a ball support, which is also worn out.
