Replacing front springs on a ŠKODA Octavia A7: instructions with photos and videos

ŠKODA Octavia A7 is one of the most popular models of the Czech brand on the Russian market, but even such a reliable car has suspension elements that wear out over time. The front springs lose their elasticity, sag or break, which leads to poor handling, uneven tire wear and driving discomfort. In this article we will look at how replace the front springs yourself on Octavia A7 (including restyled versions), what tools and spare parts will be needed, and we will also reveal the nuances that are silent about in standard manuals.

The procedure does not require special education, but will require care and compliance with safety precautions. If you have not worked with suspension before, it is better to invite an assistant - some steps (for example, tightening the springs) are difficult to complete alone. We will describe each step in detail, indicate typical mistakes and give recommendations on choosing analogues of original springs from VW Group.

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

Suspension springs are consumables with a limited resource. On Octavia A7 they serve on average 100–150 thousand km, but the period depends on the driving style, the quality of the roads and the load on the car. Here are the key symptoms indicating the need for replacement:

• 🚗 Body sagging from the front - it is visually noticeable that the car has “squatted” on the front axle, especially after loading the trunk.
• 🛣️ Deterioration in handling: the car “scours” along the road, holds its trajectory worse when cornering, and there is a “peck” when braking.
• 🔧 Knocks or squeaks in the suspension when driving over uneven surfaces (often confused with wear of struts or silent blocks).
• 🔄 Uneven tire wear - if the spring sag on one side, the tire will be “eaten” from the inner or outer part.
• 💥 Visible damage: cracks, chips or corrosion on the spring coils (be sure to inspect during seasonal wheel replacement!).

If you notice at least 2-3 signs from the list, it is worth checking the condition of the springs on the lift or pit. On the Octavia A7 with 1.4 TSI and 1.8 TSI engines, spring wear occurs earlier due to stiffer suspension settings and increased load on the front axle.

⚠️ Attention! Do not ignore spring sagging by more than 20 mm - this leads to incorrect operation of the ABS sensors and the ESP system, which can cause failures in emergency situations.

Which springs to choose: original vs analogues

Original springs for ŠKODA Octavia A7 (including facelift 2017) supplies VW Group under the articles:

Modification	Article (left/right)	Notes
Petrol 1.4/1.8 TSI, diesel 2.0 TDI (standard suspension)	5Q0 511 107/5Q0 511 108	Height 420 mm, stiffness 22–24 N/mm
1.6 TDI, 2.0 TDI (reinforced suspension)	5Q0 511 109/5Q0 511 110	Height 430 mm, rigidity 26 N/mm
RS version (sports suspension)	5Q0 511 111/5Q0 511 112	Shorter by 15 mm, stiffness 30 N/mm

The cost of original springs is from 4,500 to 7,000 rub. for a couple. If your budget is limited, you can consider high-quality analogues:

• 🔹 Lesjöfors (Sweden) - articles 5024556/5024557, rigidity corresponds to the original, resource up to 120 thousand km.
• 🔹 Sachs (Germany) - 315 520/315 521, often installed on a conveyor VW.
• 🔹 TRW — JTS534T/JTS535T, a reinforced version for severe operating conditions.
• 🔹 Moog (USA) — 81029/81030, springs with anti-corrosion coating.

When choosing analogues, be sure to check hardness (N/mm) and free height. For example, springs from Golf 7 or Audi A3 8V suitable for fastenings, but may differ in characteristics!

Necessary tools and preparation for work

To replace the front springs with Octavia A7 you will need:

Jack and supports (or lift)

Spring ties (minimum 2 pcs.)

Set of sockets and socket wrenches (13, 16, 18 mm)

Ratchet wrench and extension

Hammer and pry bar

WD-40 or similar for loosening stuck nuts

Torque wrench (optional but recommended)

New springs and a set of rubber gaskets (5Q0 511 309)

Thread compound (e.g. Liqui Moly LM40)-->

Before starting work:

1. Place the car on a level surface, tighten the handbrake and place chocks under the rear wheels.
2. Loosen the front wheel nuts (but do not remove them completely!).
3. Raise the car on a jack or lift and remove the wheel. Important: the suspension must be unloaded (the wheel hangs in the air).
4. Spray all threaded connections (strut nuts, knuckle bolts) with WD-40 and wait 10-15 minutes.

⚠️ Attention! Never work under a vehicle that is supported only by a jack! Use safety stops or sill supports.

If you don’t have spring ties, you can rent them at a car service center or buy an inexpensive set (from 1,500 rubles). Octavia A7 has springs with a high compression force - trying to tighten them with improvised means (for example, cables) can lead to injury!

Step-by-step instructions for replacing front springs

The replacement process is the same for left and right sides. Let's start with dismantling:

1. Removing the stand:
   • Unscrew the nut securing the strut to the steering knuckle (18 mm wrench). You may need to hold the bolt from the back with a pry bar.
   • Disconnect the brake hose from the bracket on the rack (carefully so as not to damage it!).
   • In the engine compartment, unscrew the three nuts securing the strut to the body (13 mm wrench). Pre-mark the position of the strut with a marker - this will help maintain alignment.
2. Spring retraction:
   • Install the ties onto the spring so that they engage at least 3 turns on each side. Tighten evenly until the spring loosens.
   • After tightening, remove the upper strut support and remove the spring along with the rubber pads.
3. Installing a new spring:
   • Check the condition of the rubber gaskets - if they are cracked or deformed, replace them (5Q0 511 309).
   • Install a new spring top turn down (there is a mark on the spring - usually a colored dot).
   • Tighten the ties until the spring is compressed to working length and reassemble the rack in reverse order.

During assembly do not tighten the nuts securing the strut to the body until the car is lowered onto its wheels! Final tightening torque:

• Nuts securing the strut to the body: 25 Nm.
• Bolt securing the strut to the knuckle: 80 Nm + 90° (if you don’t have a torque wrench, tighten “by hand” with force, but not fanaticism).

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing springs. Here are the most common:

• 🔧 Incorrect installation of the spring “upside down” - this leads to uneven load and rapid failure. Always follow the mark (usually the paint on the top turn).
• 🛠️ Ignoring rubber gaskets — they dampen vibrations and prevent corrosion. If the gaskets are worn, the spring will knock when moving.
• 🔩 Tightening the nuts - especially dangerous for aluminum steering knuckles. Use a torque wrench or tighten it in two steps: first all the way, then tighten it 1/4 turn.
• 🚘 Forgetting to check wheel alignment — after replacing the springs, the wheel alignment angles change. Even if you have marked the position of the stand, visit the stand for adjustment.

Another common problem is stuck nuts. On Octavia A7 It is especially difficult to unscrew the bolt securing the strut to the knuckle. If WD-40 doesn't help, use liquid key (for example, Mannol Rostloser) or heat the nut with a hair dryer (but do not overheat, so as not to damage the CV boot!).

What to do if the spring tie breaks?

If the tie breaks or comes off, do not try to hold the spring with your hands! Immediately lower the stand to the ground (the spring will release) and use a spare tie rod. As a last resort, you can tighten the spring with cables, but this requires experience - the coils must be fixed symmetrically on both sides, and the cable must be pulled through a lever (for example, a crowbar).

Do springs need to be replaced in pairs?

This is one of the most controversial issues. The manufacturer recommends changing the springs in pairs (left and right at the same time), but in practice many save money by installing only one new spring. Let's figure out when this is acceptable:

• ✅ One spring can be replaced, if:
  • The second spring is in perfect condition (no corrosion, cracks, subsidence).
  • The car is operated in a gentle mode (city, smooth roads).
  • You are ready to change the second spring after 10–15 thousand km.
• ❌ Be sure to change in pairs, if:
  • The car's mileage is more than 100 thousand km - the second spring is also worn out.
  • Have you noticed a difference in rigidity (for example, when driving over speed bumps, the car tilts to one side).
  • Install springs of a different stiffness (for example, switch to sports ones).

On an Octavia A7 with all-wheel drive (4x4), replacing the springs in pairs is mandatory - uneven stiffness leads to increased load on the Haldex coupling and accelerated wear of the transmission.

What else should you check when replacing springs?

While the rack is removed, it makes sense to inspect and replace the accompanying elements:

• 🔹 Shock absorbers - if they “leaked” or lost efficiency (the car sways after driving over bumps), it is better to replace them immediately. Original articles: 5Q0 413 031/5Q0 413 032.
• 🔹 Support bearings — if you hear a crunching sound when you turn the steering wheel, it’s time to change them too (5Q0 412 331).
• 🔹 Anthers and bumpers — cracked or deformed elements reduce the life of shock absorbers.
• 🔹 Silent blocks of levers — if they are worn out, it is better to combine replacement with work on the suspension.

Also note condition of brake hoses - if they are cracked or leaking, replace them (5Q0 611 721). On Octavia A7 hoses often rub against the brackets, which leads to their premature wear.

FAQ: Frequently asked questions about replacing springs on Octavia A7

Is it possible to replace springs without ties?

Theoretically yes, but it is extremely dangerous. The spring is under high tension - if the strut is weakened, it can “shoot” and cause serious injury. If there are no ties, it is better to contact the service.

How long does it take to replace?

If you have experience and tools - about 2-3 hours on both sides. If this is your first time, allow 4-5 hours (including time for joints and smoke breaks).

Do I need to do a wheel alignment after replacing the springs?

Yes, definitely! Even if you have marked the position of the rack, the wheel alignment angles will change. Postpone your visit to the stand for 1–2 days so that the springs “settle.”

Can springs from other VW Group models be installed?

Partially. For example, springs from Golf 7 or Audi A3 8V suitable for fastenings, but may differ in rigidity and height. Always check the articles and specifications!

How often should the condition of the springs be checked?

It is recommended to inspect the springs every 20–30 thousand km (for example, when changing tires seasonally). Pay attention to corrosion, cracks and subsidence. Also check the springs after strong impacts (for example, falling into a hole at speed).
