Steering rack in Nissan Almera G15 - a unit on which the safety of driving a car directly depends. One of its most vulnerable elements is boot (corrugation), protecting the mechanism from dust, moisture and dirt. Its damage or wear leads to the entry of abrasive particles into the rack, which accelerates the wear of the gear pair and oil seals. The result is steering play, power steering fluid leakage (if any) and expensive repairs.
In this article we will look at how determine whether the boot is faulty on Almera G15 (including restyled versions 2015–2019), what symptoms indicate a problem, and how to replace the corrugation yourself - taking into account the design nuances of this car. We will also compare original spare parts with analogues and give recommendations for selection.
Signs of damage to the steering rack boot on Nissan Almera G15
The first signals that the boot has become unusable often go unnoticed until more serious problems appear. Basic symptoms of corrugation wear:
- 🔍 Cracks or tears on the surface of the boot (visible upon visual inspection).
- 💧 Traces of oil or dirt on or near the corrugation - a sign that the protection is no longer airtight.
- 🔧 Extraneous sounds (creaks, knocks) when turning the steering wheel, especially on uneven roads.
- 🚗 Weighted steering wheel or uneven rotational force may indicate dirt has gotten into the mechanism.
On Almera G15 with electric power steering (EPS), a damaged corrugation often leads to system errors (For example, C1130 — malfunction of the rotation angle sensor). In versions with power steering (hydraulic booster), wear of the boot can cause fluid leak and a drop in its level in the tank.
⚠️ Attention! If traces of oil are visible on the corrugation, but there are no obvious cracks, this does not mean that the boot is intact. The damage may be on the back or inside the folds. In this case, dismantling is required for a complete diagnosis.
It is worth checking the anthers especially carefully after driving off-road or in very dusty conditions. On Almera G15 The corrugation is located close to the road, and even a small stone can break through it when moving.
Consequences of driving with a damaged boot
Many car owners put off replacing the corrugation, considering it a “trifle”. However, ignoring the problem leads to serious damage:
- 🔩 Rack and pinion wear — abrasive particles act like sandpaper, erasing metal.
- 🛢️ Failure of oil seals — dirt damages the seals, which leads to oil leaks (in the power steering) or moisture ingress (in the EPS).
- 💥 Mechanism jamming — in advanced cases, the steering rack may become sour, which is dangerous at speed.
- 💰 Expensive repairs — replacing the rack assembly will cost 3–5 times more than timely replacement of the boot.
On Nissan Almera G15 with electric power steering (models after 2016), damaged corrugation often becomes the cause Angle sensor corrosion. Replacing it costs 15–20 thousand rubles, while a new boot costs from 500 to 2000 rubles.
| Problem | Appearance time (if ignored) | Remediation cost |
|---|---|---|
| Tooth pair wear | 3–6 months | From 20,000 ₽ (rail repair) |
| Power steering fluid leak | 1–3 months | From 5,000 ₽ (replacement of oil seals + fluid) |
| EPS Sensor Corrosion | 6–12 months | From 15,000 ₽ (sensor replacement) |
| Complete replacement of the rack | 1–2 years | From 40,000 ₽ (new slats + work) |
⚠️ Attention! On Almera G15 With a mileage of more than 100 thousand km, a damaged boot can accelerate the wear of steering rods. Replacing them will cost 8–12 thousand rubles per pair, plus wheel alignment adjustment is necessary.
- Every maintenance
- Once a year
- Only when symptoms appear
- Never checked
Choosing anther: original vs analogues for Nissan Almera G15
When purchasing a new boot, it is important to consider article number and compatibility with your version Almera G15. Original corrugations from Nissan have catalog numbers:
- 📌 48520-BM40A — for models with power steering (until 2016).
- 📌 48520-4M00A — for models with EPS (after 2016).
The cost of original anthers is from 1500 to 2500 rubles. However, there are high-quality analogues on the market that are cheaper:
| Brand | Article | Price, ₽ | Features |
|---|---|---|---|
| Nissan (original) | 48520-BM40A / 48520-4M00A | 1500–2500 | Guaranteed compatibility, high quality rubber |
| Febi | 28236 | 800–1200 | Good elasticity, frost resistance |
| Sasic | 2005070 | 600–900 | Budget option, suitable for temporary replacement |
| Corteco | 22036010 | 1000–1400 | Reinforced design, long service life |
When choosing an analogue, pay attention to:
- 🔹 Material — high-quality rubber should be elastic, without cracks or sagging.
- 🔹 Complete set — the kit must contain clamps for fastening.
- 🔹 Country of manufacture — preference should be given to European or Japanese brands.
⚠️ Attention! On Almera G15 with EPS (electric power steering), the boot is shorter than on models with power steering. Installing the wrong corrugation can cause it to quickly stretch and become damaged again.
Before purchasing, compare the old boot with the new one in length and diameter. Even original spare parts may have slight variations between batches.
Tools and preparation for replacing the boot
To independently replace the corrugation with Nissan Almera G15 you will need:
- 🔧 Set of sockets and keys (10, 12, 14, 17 mm).
- 🔧 Socket wrench for unscrewing steering rods.
- 🔧 Pliers for clamps.
- 🔧 WD-40 or similar for treating rusty joints.
- 🔧 New clamps (if they are not included with the boot).
- 🔧 Jack and stops to lift the car.
Also recommended:
- 📌 Fix the steering wheel in a straight position (for example, using a seat belt).
- 📌 Clear work area from dirt so that it does not get inside the rail.
- 📌 Prepare a container for draining power steering fluid (if it is in your version).
On models with electric power steering (EPS) necessary before work disconnect batteryto avoid errors in the system. On versions with power steering you will need relieve pressure in the system by turning the steering wheel with the engine off.

Step-by-step instructions for replacing the steering rack boot
The process of replacing corrugations with Nissan Almera G15 takes 1.5–2 hours. The main thing is to take your time and follow the algorithm:
- Removing steering rods:
Unscrew the nuts securing the rods to the rack (17 mm wrench). Use a puller to avoid damaging the threads. On models with EPS, first remove the rotation angle sensor (disconnect the connector and unscrew the 2 bolts).
- Removing the old boot:
Cut or loosen the clamps, then remove the corrugation. Inspect the rack for dirt or corrosion. Clean it if necessary lint-free cloth, soaked in gasoline.
- Installing a new boot:
Apply a little silicone grease on the inner surface of the corrugation to facilitate installation. Place the boot on the rail and secure with clamps. Make sure it is not twisted or stretched.
- Reassemble in reverse order:
Install the steering rods, tighten the nuts to a torque of 40–50 Nm. For EPS, connect the steering angle sensor and check for errors (for example, via a diagnostic scanner).
On Almera G15 with electric power steering, after replacing the boot, it is necessary to calibrate the rotation angle sensor. To do this, turn on the ignition, turn the steering wheel all the way left and right, then return it to the middle position. If the error C1130 remains - a reset via diagnostic equipment will be required.
After assembly, check:
- 🔹 No play in the steering.
- 🔹 Tightness of the boot (no kinks or gaps).
- 🔹 Power steering operation (no jerks or delays).
What should I do if a knocking noise appears after replacing the boot?
A knock may indicate incorrect installation of the clamps (the corrugation rubs against the rail) or air entering the power steering system. In the first case, loosen the clamps and adjust the position of the boot. In the second, bleed the power steering system by turning the steering wheel several times with the engine running.
Common mistakes when replacing anther and how to avoid them
Even experienced car owners make mistakes that lead to repeated repairs. Let's look at the most common ones:
- 🚫 Using old clamps - they lose elasticity and do not provide tightness. Always install new ones.
- 🚫 Pulling the clamps - this can tear the corrugation. Tighten them tightly, but without fanaticism.
- 🚫 Ignoring rack cleaning — if there is dirt left inside, it will quickly damage the new boot.
- 🚫 Incorrect corrugation position — it must sit without distortion, otherwise friction will lead to rapid wear.
On Almera G15 EPS is often forgotten calibrate the rotation angle sensor, which causes the steering wheel to become “stiff” or errors to appear. They also often damage sensor wiring when dismantling, it must be carefully disconnected and fixed to the side.
Another typical problem is moisture getting inside the boot when replacing in rainy weather. If it is not possible to work in a dry room, use hair dryer to dry the rail before installing a new corrugation.
The most common reason for rapid wear of a new boot is incorrect installation of the clamps. They should fix the corrugation evenly, without pinching or gaps.
When to call for service and when to handle it yourself
Replacing the steering rack boot with Nissan Almera G15 - a task that even a beginner can handle if he has the tools. However, in some cases it is better to trust the professionals:
- 🔧 If not only the corrugation is damaged, but also the rail (wear of teeth or leakage of seals is visible).
- 🔧 If EPS errors remain after replacement (requires diagnostics with a scanner).
- 🔧 If you have no experience with steering - Assembly errors can be dangerous.
Self-repair is justified if:
- 🔹 The boot is damaged, but the rail is intact.
- 🔹 You have the necessary tools and time.
- 🔹 You are ready for possible difficulties (for example, stuck nuts).
The average cost of replacing a boot at a service center is: 1500–3000 rubles (excluding spare parts). If you are not confident in your abilities, it is better to pay for the work than to risk your safety.
On Almera G15 with mileage over 150 thousand km recommended comprehensive steering diagnostics, since boot wear is often accompanied by problems with rods or rack.
FAQ: Frequently asked questions about the steering rack boot Nissan Almera G15
Is it possible to drive with a torn boot if there are no other symptoms?
No, even a small crack allows dirt to get inside the rack. After 1–2 months, this will cause wear of the gear pair or oil seals, which will result in expensive repairs. It is better to replace the corrugation immediately after detecting a defect.
How often should the condition of the anthers be checked?
It is recommended to inspect the steering rack corrugations every 10–15 thousand km or at every maintenance. Particular attention should be paid after driving off-road or in very dusty conditions. On Almera G15 Anthers last an average of 50–80 thousand km, but the period depends on operating conditions.
Is it possible to repair a torn boot using sealant or electrical tape?
This is a temporary solution and is only suitable for emergency cases (for example, to get to the service). Sealant or electrical tape will not provide a tight seal, and dirt will still penetrate inside. A complete replacement of the corrugation is required.
What is the difference between the anthers for versions with power steering and EPS?
On Almera G15 with hydraulic booster (power steering) The boot is longer and has a different profile for attaching to the rail. On models with electric power steering (EPS) the corrugation is shorter and thinner, since there are no hydraulic elements in the design. Installing an inappropriate boot will result in rapid wear or damage.
Is it necessary to do a wheel alignment after replacing the boot?
If the steering rods were not removed during replacement or their lengths were not adjusted - no need to do wheel alignment. However, if the rods were unscrewed or play was observed, checking the wheel alignment angles is mandatory.
