ล KODA Octavia A5 is one of the most popular models of the Czech brand, but even its suspension elements wear out over time. The springs lose their elasticity, the car sags, and handling deteriorates. If you notice that the ground clearance has become lower, and extraneous sounds are heard on bumps, itโ€™s time to think about replacing it.

In this article we will look at how to choose the right springs for Octavia A5 (including versions 1.6 MPI, 1.8 TSI, 2.0 TDI and RS), what tools you will need, and we will give step-by-step instructions, taking into account typical mistakes. You will also find out whether it is worth saving on cheap analogues and how to avoid problems with wheel alignment after repair.

Signs of spring wear: when is it time to change?

Suspension springs do not break suddenly; they wear out gradually. Main symptom: the car sags (especially noticeable on a loaded car or after a long stay). If the rear wheels almost touch the fender liners, and the front โ€œnodsโ€ - this is a sure sign.

Other warning signs:

  • ๐Ÿ”Š Knocking or squeaking when driving over bumps (often confused with wear on the struts).
  • ๐Ÿš— Deterioration in handling: the car โ€œfloatsโ€ at speed and holds the road worse.
  • ๐Ÿ“ Uneven tire wear (especially along the inner edge).
  • ๐Ÿ’ง Traces of corrosion on the coils of springs (visible upon visual inspection).

On Octavia A5 Factory springs last on average 100โ€“150 thousand km, but the period depends on operating conditions. If you often drive on dirt roads or overload the trunk, the resource is reduced to 60โ€“80 thousand km.

โš ๏ธ Attention: If the spring is broken (the coils are separated or cracked), operate the machine prohibited โ€” this threatens loss of control! In this case, urgent replacement is needed, even if the rest of the springs look normal.

Which springs to choose: original vs analogues

For ล KODA Octavia A5 (including facelift FL) original springs go under the article numbers:

  • ๐Ÿ”ง Front: 1K0 511 107/108 (left/right for standard suspension).
  • ๐Ÿ”ง Rear: 1K0 513 011/012 (depending on engine and configuration).

The cost of the original is from 3,500 to 6,000 rub. for the spring. But many owners choose analogues that are cheaper by 30โ€“50%. Among the trusted brands:

Brand Article (front/back) Price (per piece), rub. Features
Lesjรถfors 5535510 / 5535518 2 200 / 2 500 Softer than the original, suitable for a comfortable ride
Boge 51-0107 / 51-0118 2 800 / 3 000 Stiffer than the original, better for sporty style
Eibach E30-51-010-02-22 / E30-51-011-02-22 4 500 / 5 000 Reinforced, for tuning (clearance โˆ’20 mm)
TRW JGS107 / JGS118 2 500 / 2 700 Optimal price/quality ratio

For versions Octavia A5 RS or Scout special springs with other articles are needed (for example, 1K0 511 107 AC for RS). Check by VIN code!

โš ๏ธ Attention: Cheap springs without a brand (for example, from AliExpress) often have incorrect stiffness or sag through 10โ€“20 thousand km. Savings in 1,000โ€“1,500 rub. may result in repeated repairs.

If you plan to install lowering springs (for example, H&R), be sure to check compatibility with your shock absorbers. Springs that are too short can cause the strut piston to strike the bump stop.

Tools and preparation for replacement

To replace springs with Octavia A5 you will need:

  • ๐Ÿ”ง Jack and supports (or lift).
  • ๐Ÿ”ง Spring ties (required! Itโ€™s dangerous to shoot without them).
  • ๐Ÿ”ง Set of sockets and keys: 13, 16, 18, 21 mm.
  • ๐Ÿ”ง WD-40 or a similar composition for unscrewing stuck bolts.
  • ๐Ÿ”ง Torque wrench (for proper tightening).
  • ๐Ÿ”ง Hammer and chisel (in case of rusted nuts).

Also prepare:

  • ๐Ÿ“‹ Marker for marks (so as not to confuse the sides).
  • ๐Ÿงค Gloves and glasses (tensioned springs can cause injury!).
  • ๐Ÿš— Wheel chocks (if you work on a jack).

Important: Replacing springs necessarily swipe in pairs on the same axis (for example, both front or both rear). Otherwise, the suspension will work unevenly, which will lead to the car pulling to the side.

Step-by-step instructions: replacing front springs

Front springs on Octavia A5 They are more difficult to change than the rear ones, due to the need to disassemble the rack. Follow the algorithm:

  1. Remove the wheel and clean the arch from dirt. Unscrew the shock absorber rod nut (you will need a wrench 21 mm and hexagon on 6 mm to fix the rod).
  2. Disconnect the brake caliper (do not disconnect the hose!) and hang it on a wire.
  3. Unscrew the rack mounting bolts to the steering knuckle (2 bolts 18 mm).
  4. Remove the rack assembly and clamp it in a vice. Use zip ties to compress the spring and release the support bearing.
  5. Replace the spring, check the condition of the bumper and boot. Reassemble the stand in reverse order.

Critical point: when assembling the rack, make sure that the lower coil of the spring fits exactly into the groove of the cup. If the spring is crooked, it will creak and wear out quickly.

Tightening torques (Nm):

  • ๐Ÿ”ฉ Shock absorber rod nut: 50โ€“60.
  • ๐Ÿ”ฉ Bolts securing the strut to the knuckle: 80โ€“90.
  • ๐Ÿ”ฉ Nuts securing the strut to the body: 45โ€“55.
What to do if the shock absorber rod nut does not unscrew?

If the nut is stuck, try:

1. Process it WD-40 and wait 10โ€“15 minutes.

2. Lightly tap the edges of the nut with a hammer using a drift.

3. Use an impact wrench (if available).

4. As a last resort, cut new edges with a grinder and unscrew them with a gas wrench.

Do not use excessive force - you may break the shock absorber rod!

Replacing rear springs: easier, but there are nuances

Rear springs on Octavia A5 can be changed without disassembling the rack, but require care:

  1. Raise the car and remove the wheel. Place a support under the beam (for example, a wooden block) so that it does not sag when removing the spring.
  2. Unscrew the lower shock absorber bolt (key to 16 mm).
  3. Loosen the upper spring mounting nut (it is located in the trunk under the trim).
  4. Carefully lower the beamto release the spring. Remove it and install a new one.

On the rear axle Octavia A5 A problem that often occurs is: bottom spring cup sticks to the beam. If it does not move, use a puller or carefully pry it off with a pry bar (do not damage the rubber spacer!).

Tightening torques for rear springs:

  • ๐Ÿ”ฉ Top fastening nut: 40โ€“50 Nm.
  • ๐Ÿ”ฉ Shock absorber lower mounting bolt: 70โ€“80 Nm.
๐Ÿ’ก

After replacing the rear springs, be sure to check the operation of the handbrake - sometimes the cables require adjustment due to the changed position of the beam.

Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing springs. Here are the most common:

  1. Incorrect spring tension:

    If the ties are installed asymmetrically, the spring may โ€œshootโ€ when loosened. Always ensure that the clamps are positioned on opposite turns and tightened evenly.

  2. Ignoring checking shock absorbers:

    Worn struts will quickly kill new springs. Before replacing, check the shock absorbers for leaks and play. If they leak, replace them along with the springs.

  3. No marks during disassembly:

    On Octavia A5 the bolts securing the struts to the knuckle have eccentrics for adjusting the camber. If you do not mark their position, after assembly you will have to go to the wheel alignment.

  4. Saving on rubber spacers:

    Old rubber cushions between coils of springs often crack. Their cost is cheap (200โ€“300 rub.), but if not replaced, the new springs will squeak.

Another common problem is incorrect selection of spring stiffness. For example, if you put on Octavia A5 1.6 MPI springs from RS, the suspension will become too stiff, and the ground clearance will decrease by 30โ€“40 mm, which is unsafe for Russian roads.

What to do after replacement: wheel alignment and running in

After replacing the springs necessarily do:

  1. Checking wheel alignment angles (wheel alignment). Even if you carefully assembled everything according to the marks, the geometry of the suspension could change.
  2. Run-in: first 100โ€“200 km Avoid sharp turns and high speeds so that the springs โ€œsettleโ€ into the cups.
  3. Control check through 500 km: Inspect the springs for cracks, check the tightness of the bolts.

If after replacement there is sidestepping, possible reasons:

  • ๐Ÿ”ง The eccentrics on the front struts are installed incorrectly.
  • ๐Ÿ”ง Different spring stiffnesses (for example, one is original, the other is an analogue).
  • ๐Ÿ”ง The wheel bearing is damaged (check the play).

Wheel alignment cost for Octavia A5 - from 1,500 to 2,500 rub. for one axis. Do not skimp on this procedure: incorrect angles will lead to rapid tire wear and poor handling.

If after replacing the springs the car has become too stiff, check the tire pressure - it can be reduced slightly (by 0.2โ€“0.3 bar) for comfort.

FAQ: Frequently asked questions about replacing springs on Octavia A5

Is it possible to replace only one spring if the second one is normal?

No! Springs are always replaced in pairs on the same axle (front or rear). Even if the second one looks normal, its stiffness is already different from the new one, which will lead to an imbalance in the suspension. The exception is if you install a set of new springs with the same characteristics.

How long does it take to replace springs?

If you have experience and tools:

  • ๐Ÿ”ง Front axle: 3โ€“4 hours (with removal of racks).
  • ๐Ÿ”ง Rear axle: 1.5โ€“2 hours.

The service work will cost 4,000โ€“7,000 rub. per axle (excluding spare parts).

Which springs are better for lowering: Eibach or H&R?

Both brands are high quality, but there are nuances:

  • Eibach Pro-Kit: understatement by 20โ€“30 mm, maintains comfort.
  • H&R: understatement by 30โ€“40 mm, stiffer, suitable for sporty driving.

For Octavia A5 with engines 1.8 TSI or 2.0 TDI better Eibach โ€” they are softer on uneven surfaces. For RS you can take it H&R.

Do shock absorbers and springs need to be replaced?

Not required, but recommended if:

  • ๐Ÿ”ง Shock absorbers are leaking or play.
  • ๐Ÿ”ง Mileage exceeds 80โ€“100 thousand km.
  • ๐Ÿ”ง You install springs with a different stiffness (for example, sports ones).

New springs + old shock absorbers reduce the life of both elements.

Is it possible to drive with one broken spring?

Absolutely not! A broken spring results in:

  • ๐Ÿšจ Loss of controllability (the car may โ€œsteerโ€ to the side).
  • ๐Ÿšจ Uneven wear of tires and bearings.
  • ๐Ÿšจ Risk of damage to the body (for example, the wheel may hit the fender liner).

If the spring is cracked but still holds, you can temporarily go to a service center at a speed of no more than 40 km/h.
