Car rear suspension Skoda Octavia A5 It is subject to heavy loads, especially on Russian roads. One of the key elements that ensure smooth running and protection of the shock absorber is a breaker. Over time, the rubber part loses its properties, collapses and ceases to perform its functions, which leads to accelerated wear of the entire shock absorber rack.
Ignoring the symptoms of malfunction can lead to the fact that the metal shock absorber stem will begin to beat against the body, causing its deformation and depressurization of the osteoil. Replacing the breaker is a relatively simple procedure that can be performed independently, if you know the design features of the suspension model. Octavia A5 and follow the sequence of actions.
Symptoms of wear of the breaker and signs of malfunction
Determine that the jackpot Skoda Octavia A5 requires replacement, it is possible for several characteristic features that appear during operation. The most obvious symptom is the appearance of deaf knocks or blows in the back of the body when passing irregularities, pits or lying policemen. These sounds are often confused with a malfunction of the shock absorber itself, but the root cause may be precisely the loss of elasticity of the damping element.
In addition to extraneous sounds, it is worth paying attention to the appearance of the suspension. If you see that there are deep cracks, ruptures or marks of severe abrasion on the shock absorber rod or on the rubber part itself, this is a direct signal to replace. In some cases, the breaker can simply fall out of the landing place, which makes it impossible for it to work properly.
- π The appearance of shocks in the rear suspension when driving on irregularities.
- π Visual detection of cracks, tears or loss of rubber shape.
- π§ Shock absorber leaks caused by damage to the rod due to impact on the breaker.
- π Change in the level of the rear of the car or uneven tire wear.
β οΈ Attention: Ignoring knocks in the suspension can lead to the destruction of the lower Bushing of the lever or deformation of the body at the place of attachment of the shock absorber.
It is important to note that the jack often wears out along with the anther kit. If the anther is torn, dirt and moisture enters the mechanism, which accelerates the destruction of the breaker rubber. Therefore, if problems with the anther are detected, it is strongly recommended to check the condition of the damper.
Selection of spare parts and necessary tools
Before starting work, it is necessary to choose the right components. For the model Octavia A5 They are the original parts of the VAGand quality analogues from proven brands, such as Febi Bilstein, SWAG or Kayaba. The original jack number for the rear rack usually begins with a prefix. 1K0But before ordering, be sure to check the VIN code of your car, as the suspension may vary depending on the year of production and engine type.
To do the job, you will need a standard set of automotive tools. Pay special attention to the presence of a spring remover, since without it it it is almost impossible to safely compress the spring and dismantle the knot. Also, do not forget to prepare a jack and reliable stands to fix the car in an elevated state.

- π¦ WD-40 liquid or analogue for processing threaded joints.
- π οΈ The sleeves are in the water (for safety reasons).
Don't skimp on the quality of the rubber. Cheap hard rubber breakers quickly crack in the cold, and too soft can not withstand the loads and deform. The use of non-original breakers with improper rigidity can lead to accelerated failure of the shock rack after 5-10 thousand kilometers of run.

Preparation of the car and dismantling of the rack
Work should be carried out on a flat surface with a hard coating. Lock the front wheels with recoil stops to exclude accidental movement of the car. Lift the back of the car with a jack and install it on reliable stands. Remove the wheel to access the top of the shock absorber.
To dismantle the rack, the upper nut of the shock absorber attachment must be unscrewed. It is accessed from the trunk. Remove the decorative plastic stub and, holding the rod with a key or a special collar, unscrew the nut. Be careful: under the nut is a cup and a rubber pad that may fall out.
Then move to the bottom of the suspension. Unscrew the bolt of the shock absorber attachment to the swivel fist or lever. Depending on the modification of the suspension, the bolt can be very boiling, so pre-treat it abundantly penetrating lubricant. If the bolt fails, use a hammer and chisel to rip it off the spot.
βοΈ Rear rack removal
β οΈ Warning: Never try to unscrew the nut of the rod if the spring is in a compressed state without using a removable - this can lead to injury or breakage of the tool.
After unscrewing all the fasteners carefully remove the shock absorber rack. In some cases, this will require the help of a partner, since the weight of the node along with the spring is quite large. Make sure nothing touches the brake hoses or ABS wiring.
Disassembly of the knot and replacement of the breaker
The removed rack must be installed on a workbench or a special stand for compressing the spring. Install the springs from opposite sides so that they reliably fix the turns. Slowly compress the spring until the load on the upper support disappears. Only then can the rod be completely removed.
After removing the nut, disassemble the knot: remove the upper support, cup, old breaker and anther. Carefully examine the shock absorber rod. It should not be scratched, rust or traces of wear. If the rod is damaged, replacing only the breaker does not make sense - a complete replacement of the shock absorber is necessary.
- π§Ή Clean the rod and seats of old dirt and rubber residues.
- π Check the condition of the bearing and upper support.
- π’οΈ Apply the lubricant to the new jack and anther for easy installation.
What to do if the rod is damaged?
If there are even minor scratches or rust on the rod, the shock absorber oil will not be able to hold the oil. In this case, it is recommended to replace the shock absorber entirely, since the repair of the osel oil is often a temporary solution.
Install a new breaker on the stock, making sure that he sat on his seat tightly and without distortion. The dust is put on top of the jack. Collect the knot in reverse sequence: upper support, spring, cup. It is important to ensure that the spring stands in its grooves on the support cup and the body of the shock absorber.
Proper installation of the spring in the grooves of the cup is critical for the safe operation of the suspension and prevent its loss on the go.
Installation of the rack and final assembly
Before final assembly, unplug the springs' removable and remove them. Make sure the unit is assembled carefully, all the details are in their places. Raise the rack under the car and combine the mounting holes of the rod with the upper support. Insert the stem and twist the nut, keeping the stem from scrolling.
Then combine the bottom of the shock absorber with the lever and insert the mount bolt. Tighten the bolt with the right moment. Remember that the lower mount is often tightened after the car is lowered on the wheels, so as not to load the Silent blocks in suspension.
Lower the car to the ground and tighten all bolts with the required force. Check the suspension by swinging the back of the car several times. If there are no knocks and the shock absorber works smoothly, you can consider the work done. Do not forget to tighten the nut of the rod to the end, as in limbo access to it can be difficult.
Nuances of operation and prevention
After replacing the breaker, attention should be paid to the diagnosis of the entire suspension. Worn-out solar panels or ball supports can create additional loads that will accelerate the wear of new parts. Check the condition of the rubber suspension elements regularly, especially after the winter period of using reagents.
The cleanliness of the suspension also plays an important role. Mud and sand, falling on the shock absorber rod, act as an abrasive, quickly grinding chromium and damaging the omentum. Washing the bottom and suspension will help extend the life of new breakers and shock absorbers.
| Component | Average service life | Symptoms of wear | Recommended Action |
|---|---|---|---|
| Bumper | 60,000 - 80,000 km | Knock, cracks. | Replacement of the anther kit |
| Boot | 40,000 - 60,000 km | Breaks, dirt on the rod | Replacement upon detection of defects |
| Shock absorber | 100,000 - 120,000 km | Leak, knock, swing. | Replacement (pair on axle) |
| Support bearing | 80,000 - 100,000 km | Knocking sound when turning the steering wheel | Replacement when knocking or jamming |
β οΈ Warning: Replace shock absorbers and breakers strictly with a pair on one axis. Different stiffness and characteristics of the suspension on the left and right can lead to instability of the car during braking.
Frequently Asked Questions
Can you replace the slack without removing the slack?
Theoretically, if you have access to the top mount, you can try, but in practice it is extremely inconvenient and risky. The spring is under tremendous stress, and without removing the rack, it is impossible to safely dismantle the old breaker and install a new one. It is recommended to remove the entire rack.
Do I need to do a wheel alignment after replacement?
When replacing only the breaker and anther, the angles of the wheel installation do not change, so descent-shattering is not required. However, if you replaced the shock absorbers or levers themselves, or if the bolts of the levers mounting were broken during disassembly, then checking the geometry of the suspension is mandatory.
How to distinguish an original bumper from a fake?
Original parts from VAG have a clear marking, a smooth rubber structure and packaging with a logo. Counterfeits often have stiffer rubber, uneven edges and no clear inscriptions. Always check the article on the box and check it against the catalog.
What happens if you donβt change the worn-out jack?
In the absence of a breaker, the shock absorber rod will rest on the metal base or body, which will lead to impacts. This will cause rapid destruction of the stock, rupture of the osteoil and leakage of oil. As a result, the shock absorber will fail, and repair will cost much more than a simple replacement of the breaker.
Before starting work, be sure to take a picture of the circuit of connecting the wires and the location of the bolts on the rear rack, so as not to forget the sequence of the assembly.
