Rear suspension arms ล koda Octavia A5 (2004โ€“2013) is a critical element affecting the vehicle's handling, comfort and safety. Over time, the silent blocks and ball joints in the levers wear out, which leads to knocking, the car pulling to the side, or uneven tire wear. In this article, we will look at how to determine the malfunction, which levers to choose (original or analogues), and how to replace them yourself, taking into account the nuances of a particular model.

Feature rear multi-link suspension Octavia A5 โ€” the presence of four levers on each wheel (upper, lower, longitudinal and transverse). Their design depends on the type of drive (front or full 4x4) and year of manufacture. For example, restyled versions (after 2008) received reinforced silent blocks, and models with engines 1.8 TSI or 2.0 TDI often equipped with levers with different catalog numbers. We have collected up-to-date data on part numbers, compatibility and common problems to help avoid mistakes during repairs.

Octavia A5 rear suspension: what levers are there and what they are responsible for

Rear suspension ล koda Octavia A5 built according to the scheme multi-link design, where each element performs its function:

  • ๐Ÿ”ง Upper arm โ€” fixes the wheel in a vertical plane, is responsible for stabilization when turning. Most often the silent block fails.
  • ๐Ÿ”ง Lower arm โ€” takes up the main loads during braking and acceleration. It wears out faster than others due to high load.
  • ๐Ÿ”ง Trailing arm โ€” controls the longitudinal displacement of the wheel (especially important for all-wheel drive versions). In models with 4x4 The attachment to the subframe often breaks.
  • ๐Ÿ”ง wishbone โ€” provides lateral stability. It fails less often, but its wear causes the car to โ€œyawโ€ at speed.

On cars with engines 1.6 MPI or 1.4 TSI levers may differ in geometry from versions with 2.0 FSI or diesel engines. For example, the lower arms on Octavia A5 4x4 have reinforced silent blocks with the article number 1K0 505 507/508, while front-wheel drive models use 1K0 505 505/506.

๐Ÿ“Š What type of drive does your Octavia A5 have?
  • Front
  • Full (4x4)
  • I don't know

It is important to consider that on the restyled versions (2008โ€“2013), the manufacturer changed the materials of the silent blocks - they became less susceptible to cracking, but also cost more. When replacing levers with pre-restyle models (2004โ€“2008) it is recommended to install updated parts with facelift articles, if the design allows it.

Signs of a bad rear control arm: when to replace it

Wear on the rear control arms appears gradually, and many drivers attribute the symptoms to โ€œroad conditionsโ€ or tire wear. However, ignoring problems can lead to loss of control at speed or wheel bearing damage. Main features:

  • ๐Ÿš— Knock in the rear when driving over bumps (especially at low speeds). Most often it indicates wear on the silent blocks of the upper or lower arm.
  • ๐Ÿš— Pulling the car to the side when moving in a straight line. Occurs due to play in the transverse arm or uneven wear of the silent blocks.
  • ๐Ÿš— Uneven rear tire wear (especially along the inner edge). Indicates a wheel alignment violation due to play in the levers.
  • ๐Ÿš— Vibration on the steering wheel when braking. May be associated with deformation of the trailing arm (relevant for Octavia A5 4x4).

For an accurate diagnosis, it is necessary to check the play of the levers on the lift or inspection hole. Silent blocks are considered worn out if:

  • ๐Ÿ” They show cracks or tears in the rubber.
  • ๐Ÿ” The bushing rotates inside the metal cage (checked with a pry bar).
  • ๐Ÿ” The play exceeds 1โ€“2 mm when rocking the lever by hand.
โš ๏ธ Attention: On all-wheel drive Octavia A5 Wear on the rear control arms can damage the drive shaft. If you hear a crunch when turning, check not only the levers, but also the CV joints.

Choice of rear levers: original vs analogues, articles and prices

When replacing levers, owners Octavia A5 are faced with a choice: buy original parts or analogues. Original levers from ล koda/VW guarantee compatibility, but cost 2โ€“3 times more than analogues. The table below shows a comparison of popular brands indicating article numbers and average prices (for 2026):

Lever type Original (item) Price, rubles Analogue (brand) Price, rubles
Upper (left/right) 1K0 505 501A / 1K0 505 502A 8 000โ€“12 000 Lemforder (33476 01) 4 500โ€“6 000
Bottom (left/right) 1K0 505 505 / 1K0 505 506 9 000โ€“13 000 TRW (JTC1242) 5 000โ€“7 500
Longitudinal (for 4x4) 1K0 505 511 / 1K0 505 512 11 000โ€“15 000 Febi (23476) 6 000โ€“8 500
Transverse 1K0 505 509 / 1K0 505 510 7 000โ€“10 000 SASIC (9030032) 3 500โ€“5 000

When choosing analogues, pay attention to:

  • ๐Ÿ”น Silent block material: the best options are polyurethane (last longer, but more expensive) or rubber with reinforcement (for example, Lemforder).
  • ๐Ÿ”น Complete set: some brands (eg TRW) they sell levers with already pressed silent blocks, others require a separate purchase of bushings.
  • ๐Ÿ”น Year of manufacture of the car: levers for Octavia A5 before 2008 may not be suitable for facelift due to the changed geometry of the fastenings.

When purchasing control arms for the all-wheel drive version, check for the "4Motion" or "Haldex" label on the packaging. Parts are not suitable for front-wheel drive models!

Step-by-step instructions for replacing Octavia A5 rear control arms

Replacing levers requires an inspection hole or a lift, as well as a special tool: a silent block puller, a torque wrench and a press-in mandrel. If you have little experience, it is better to entrust the work to the service, since incorrect installation can lead to wheel alignment or damage to the subframe.

โ˜‘๏ธ Preparing to replace levers

Done: 0 / 4

Work order (using the example of the lower arm):

  1. Unscrew the nuts securing the lever to the subframe and hub (use sockets on 16 and 18).
  2. Using a puller, press the silent blocks out of the lever. If they โ€œstickโ€, heat the attachment point with a hair dryer.
  3. Install new silent blocks after lubricating them with soapy water (do not use oil - it corrodes the rubber!).
  4. Screw the lever into place, observing the tightening torque:
    • ๐Ÿ”ฉ Nuts for fastening to the subframe: 70โ€“90 Nm.
    • ๐Ÿ”ฉ Hub mounting bolt: 100โ€“120 Nm.
  • Repeat the procedure for the remaining levers. After replacement, be sure to do wheel alignment!
  • โš ๏ธ Attention: On all-wheel drive Octavia A5 When replacing trailing arms, it is necessary to check the condition of the subframe fastenings. If the bolts are rusty or deformed, replace them with new ones (part number N 908 132 02).
    What happens if you donโ€™t replace silent blocks on time?

    Ignoring the wear of silent blocks leads to:

    - Increased tire wear (up to 30% faster).

    - Risk of the lever coming off on uneven surfaces (especially important for the lower lever).

    - Damage to the wheel bearing (replacement cost - from 15,000 rubles).

    - Loss of controllability at high speed (the car may โ€œscourโ€ the lane).

    Typical mistakes when replacing levers and how to avoid them

    Even experienced craftsmen sometimes make mistakes that shorten the life of new levers or lead to additional expenses. Here are the most common:

    • โŒ Using a percussion instrument (hammer) for pressing silent blocks. This leads to microcracks in the rubber and rapid wear. Solution: Use only a hydraulic or screw puller.
    • โŒ Incorrect tightening torque. Overtightened bolts deform the silent blocks, and weak tightening leads to backlash. Solution: Always use a torque wrench.
    • โŒ Replacing only one lever (for example, only the lower one). This upsets the balance of the suspension and accelerates wear of adjacent elements. Solution: change levers in pairs (left + right).
    • โŒ Ignoring subframe check. On Octavia A5 After 10 years, the mounting points of the levers often rust. Solution: clean and treat them with anticorrosive (Dinitrol or Movi).

    Another common problem is purchasing levers without taking into account the modification of the car. For example, on Octavia A5 Scout (all-terrain) reinforced levers with articles are used 1K0 505 515/516, which are not suitable for standard versions. Always check the vehicle's VIN number with catalogs ETKA or Elcats.

    1. Correct installation of silent blocks (they must be oriented according to the marks).

    2. Condition of the fastening bolts (possibly loosened during running-in).

    3. Integrity of CV joint boots (on all-wheel drive versions).-->

    Cost of service work vs independent replacement

    Cost of replacing rear control arms ล koda Octavia A5 in services varies depending on the region and complexity of the work. The table below shows average prices (for 2026) for Moscow and the regions:

    Type of work Moscow, rubles Regions, rubles Working hours
    Replacing one lever (without silent blocks) 2 500โ€“3 500 1 800โ€“2 500 1โ€“1.5 hours
    Replacing all four levers with silent blocks 12 000โ€“18 000 8 000โ€“12 000 4โ€“6 hours
    Replacing silent blocks (without removing levers) 1,500โ€“2,000 per piece 1,000โ€“1,500 per piece 0.5โ€“1 hour
    Wheel alignment (required after replacement) 1 500โ€“2 500 1 000โ€“1 800 30โ€“40 minutes

    Replacing it yourself will cost less, but will require:

    • ๐Ÿ› ๏ธ Instrument: silent block puller (~2,000 rubles), torque wrench (~3,000 rubles), press-in mandrels.
    • ๐Ÿ•’ Time: 6โ€“8 hours for beginners, 3โ€“4 hours for experienced craftsmen.
    • ๐Ÿ”ง Additional costs: new fastening bolts (~500 rubles), lubricant for silent blocks (~300 rubles).

    If you decide to change the levers yourself, keep in mind that on all-wheel drive versions the process is more complicated due to the need to remove the drive shaft. In this case, savings on the service may result in additional costs for correcting errors.

    Frequently asked questions about Octavia A5 rear control arms

    Is it possible to drive with worn silent blocks if there are no knocks?

    No, even in the absence of knocking, worn silent blocks worsen handling and increase the load on other suspension elements. For example, play in the control arm causes uneven tire wear and can damage the wheel bearing. It is recommended to replace them at the first sign of rubber cracking.

    Which silent blocks are better - rubber or polyurethane?

    Polyurethane silent blocks (Powerflex, Whiteline) last longer (up to 100,000 km) and withstand loads better, but they are more expensive and stiffer - this can worsen comfort on rough roads. Rubber ones are cheaper and softer, but wear out faster (40โ€“60,000 km). For everyday driving, high-quality rubber silent blocks from Lemforder or TRW.

    Do I need to change the levers in pairs?

    Yes, levers are always replaced in pairs (left + right), even if wear is visible only on one side. This is due to the fact that the suspension must work symmetrically. If you replace only one lever, the alignment will be disrupted, and the new lever will experience increased loads.

    How often should you check your rear control arms?

    It is recommended to inspect the levers and silent blocks every 20,000โ€“30,000 km or at every maintenance. Particular attention is paid to cars over 10 years old and cars driven on bad roads. Signs for an unscheduled inspection: knocking, pulling to the side, uneven tire wear.

    Is it possible to restore silent blocks without replacing the lever?

    Technically, you can press out the old silent blocks and press in new ones, but this is only advisable if the lever itself is not deformed and has no cracks. The cost of replacing silent blocks is often comparable to the price of a new lever (especially if analogues are used), so restoration is justified only for original levers of premium brands.
