Rear wheel bearing Nissan Almera G15 (2012–2019) - a part that often fails after 80–120 thousand km. Its malfunction not only impairs ride comfort, but also creates a real safety hazard: a damaged bearing can block the wheel while moving or lead to loss of control. Owners Almera G15 Often faced with the problem of late diagnosis - a hum at speed is attributed to tires or transmission until the situation becomes critical.
In this article we will look at how accurately determine rear bearing wear (including in the early stages), what tools will be needed for replacement, and why saving on spare parts can result in repeated repairs after 20 thousand km. Let us dwell separately on unique feature of the hub assembly Almera G15 — absence of a separate inner bearing ring in some configurations, which complicates the selection of analogues.
Signs of a bad rear bearing: how not to confuse it with other problems
The main symptom of wear is monotonous hum or howl, which increases with increasing speed. However, on Nissan Almera G15 this sound can be masked as tire noise or the operation of the rear axle gearbox (on versions with automatic transmission). To avoid mistakes, pay attention to the nuances:
- 🔊 Sound localization: when turning right the hum gets louder - the problem is left bearing, and vice versa. This is due to load redistribution.
- 📉 Speed dependent: the noise appears already at 40–60 km/h and disappears when braking the engine (in neutral). If the hum is heard even when parked when the wheel is rocking, the bearing is in critical condition.
- 🔥 Hub overheating: After driving, touch the center of the wheel (carefully!). If the temperature is noticeably higher than on other wheels, the bearing operates with increased friction.
- 🛑 Wheel play: with the wheel hanging (on a jack), try to swing it in a vertical plane. Play of more than 0.5 mm is a direct sign of wear.
On Almera G15 with ABS a faulty bearing can cause a fire ABS error indicator on the dashboard. This occurs due to damage pulse ring, which is integrated into the hub. Error code C1130 (malfunction of the rear wheel speed sensor) often accompanies bearing wear.
⚠️ Attention! If, while driving, vibration appears on the steering wheel or body, and the hum turns into crunching or grinding — operation of the vehicle is prohibited! The risk of wheel seizure at speeds above 60 km/h is more than 70%.

Rear hub design Nissan Almera G15: what you need to know before replacing
Rear hub Almera G15 has non-demountable design — the bearing is pressed into the hub housing and cannot be replaced separately. This distinguishes the model from many competitors (for example, Kia Rio or Hyundai Solaris), where the bearing can be replaced separately. The table below shows the key features of the node:
| Parameter | Characteristics | Note |
|---|---|---|
| Bearing type | Double-row ball (or roller, depending on year) | On cars 2012–2014. roller bearings with increased load capacity were installed |
| Bore diameter | 42 mm (internal), 72 mm (external) | It is critical to check when purchasing analogues - an error of 0.1 mm will lead to runout |
| ABS integration | Impulse ring integrated into the hub | When replacing, reinstallation of the ABS sensor is required (part number 40520-BM00A) |
| Tightening torque | 180–200 Nm (hub nut) | Over-tightening leads to premature wear, under-tightening leads to play. |
Important point: on Almera G15 with disc brakes (configurations Comfort+ And Tekna) the hub has additional collar for fastening the brake disc. When purchasing a spare part, check whether it is suitable for your version of the brake system. On basic models with drum brakes, the hub is simpler and cheaper.
The manufacturer recommends replacing the hub assembly (original article number - 40530-BM000 or 40530-BM00A for cars with ABS). However, there are high-quality analogues on the market from SKF (VKB 3455), NTN (512218) or Koyo (DAC40720042), which will cost 2–3 times less. The main thing is to avoid no-name brands: bearings from "NoName China" serve no more than 10 thousand km.
Before purchasing a hub assembly, check availability warranty sticker on the packaging. Counterfeits are often sold without it, and original parts Nissan always have a holographic sticker with a serial number.
Step-by-step instructions for replacing the rear wheel bearing
To replace you will need:
- 🔧 Set of sockets (17, 19, 22 mm) and wrench with extension
- 🔨 Wheel bearing puller (or press)
- 🔥 Gas burner or hair dryer (to heat the hub)
- 🛠 Torque wrench (required!)
- 🧲 Magnet for removing circlips
If you don't have a puller, you can get by homemade device of two M12 bolts, a nut and a metal plate. However, the risk of damage to the new hub increases.
Loosen the hub nut (while the car is on wheels)|Jack up the car and remove the wheel|Disconnect the brake caliper (on disc brakes) or drum|Remove the ABS sensor (do not pull the wires!)|Clean the seat from dirt and rust-->
Replacement algorithm:
Remove the hub protective cap and unscrew the nut (tightening torque - 180 Nm). If the nut does not budge, use
WD-40and an extension for the wrench.Remove the brake disc or drum. On disc brakes, you will have to unscrew the caliper (14 mm bolts) and hang it on a wire so as not to damage the hose.
Disconnect the ABS sensor (the connector is usually located on the strut). Do not pull on the wires - there is a risk of breaking the wiring!
Press the hub out of the axle. To do this, you will need a puller or a hammer with a wooden spacer (hit the inner race of the bearing!).
Install the new hub, having previously lubricated the seat
litholom-24. Tighten the nut in 2 stages: first to 100 Nm, then tighten to 180–200 Nm.
⚠️ Attention! After bearing replacement necessarily check the wheel runout on a balancing stand. The permissible value is no more than 0.3 mm. If the runout is greater, there are two possible reasons: a poor-quality hub or damage to the axle (the lever needs to be replaced).
What to do if the hub cannot be removed?
If the hub is stuck to the axle, use the following method:
1. Heat the hub with a gas burner (do not overheat - maximum 200°C).
2. Cool it down quickly WD-40 or ice (thermal shock effect).
3. Try removing again with the puller.
Do not hit the hub with a hammer without a spacer - this will deform the seat!Cost of work and spare parts: where is cheaper and more reliable?
Rear wheel bearing replacement cost Nissan Almera G15 varies depending on the region and type of service station:
| Service type | Cost of work (for 1 side), ₽ | Spare part cost, ₽ | Total, ₽ |
|---|---|---|---|
| Official dealer Nissan | 4 500–6 000 | 8,000–12,000 (original) | 12 500–18 000 |
| Specialized car service | 2 500–3 500 | 3,000–5,000 (analog SKF/NTN) | 5 500–8 500 |
| Garage craftsmen | 1 500–2 500 | 2,000–3,500 (budget equivalent) | 3 500–6 000 |
| Self-replacement | 0 (with tool present) | 2 000–5 000 | 2 000–5 000 |
Savings on spare parts often cost you repeated repairs. For example, hubs from "Phenox" or "Pilgrim" They serve an average of 15–20 thousand km, after which they begin to play. The best option in terms of price/quality ratio - SKF or NTN. Original hubs Nissan more expensive, but their service life exceeds 100 thousand km if installed correctly.
If you decide to change the bearing yourself, please note: hidden costs:
- 🔧 Renting a puller (if you don’t have your own) - 500–1,000 ₽/day.
- 🔨 Purchase of a torque wrench (from 1,500 ₽).
- 🚗 Wheel balancing after replacement - 500–800 ₽.
Replacing a bearing at a service station with a guarantee will cost less than repairing it yourself and purchasing a tool. However, if you already have a puller and keys, the savings will be up to 50%.
Common replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that shorten the service life of a new bearing. Here are the most common:
Retightening the hub nut. The tightening torque exceeds 200 Nm → the bearing overheats and fails after 5–10 thousand km. Always use a torque wrench!
Ignoring ABS pulse ring. If the ring is damaged during installation or the sensor is not secured, the ABS system will generate an error
C1130.Saving on lubrication. The trunnion seat must be clean and covered with a thin layer
Litol-24orMolykote BR2-Plus. Dry installation leads to corrosion and souring.Using a percussion instrument. Hitting a new hub with a hammer is a sure way to deform it before installation. Press or puller only!
Failure to check runout. Even a new bearing may have a manufacturing defect. After installation, be sure to check the runout on the stand.
Another typical problem is incompatibility of hubs from different configurations. For example, if on Almera G15 with drum brakes, install the hub from the version with disc brakes, the brake drum will not fit tightly, which will lead to vibrations during braking.
⚠️ Attention! If after replacing the bearing there is metallic grinding at low speeds, stop immediately! Most likely it was damaged during installation o-ring, and dirt got into the bearing. Further movement will destroy it within 100–200 km.
How to extend the life of the rear bearing: prevention
Bearing life at Nissan Almera G15 depends not only on the quality of the part, but also on driving style and care. Here's what will help avoid premature wear:
- 🚿 Washing wheel arches in winter. Salt and reagents corrode bearing seals, which leads to moisture ingress and corrosion.
- 🛣 Avoiding potholes and speed bumps at speed. Impact loading reduces bearing life by 30–40%.
- 🔧 Regular play check. Every 10 thousand km, jack up the car and check the wheel for radial play.
- 🔥 Hub temperature monitoring. After a long trip (more than 100 km), touch the center of the wheel. If it is hot, the bearing operates with increased friction.
If you often drive off-road or in dusty conditions, install additional anthers on the hubs. They cost 300–500 rubles per pair, but increase the bearing life by 20–30%. It is also useful to treat the hub seat once a year WD-40 or Liqui Moly Kupfer-Spray for protection against corrosion.
When replacing a summer/winter tire, always check the condition of the wheel bearing. Tire service technicians often notice play or overheating before the car owner does.
Alternative repair methods: when replacement is not necessary
In some cases, you can do without completely replacing the hub:
Bearing tightening. If the play is minimal (up to 0.3 mm) and there is no hum, you can try tightening the hub nut. However, this is a temporary solution - after 5-10 thousand km the problem will return.
Repair kits. For some hub analogues (for example, SKF) individual bearings and seals are sold. But for Almera G15 this is risky - turning of the seat is required.
Restoring the ABS impulse ring. If the problem is only in the ABS sensor (error
C1130), only the ring can be replaced (item no.40525-BM000) without removing the hub.
However, these methods do not guarantee long-term results. For example, tightening the nut can eliminate play, but if the bearing is already worn out, it will begin to heat up and quickly collapse. Repair kits are only suitable for experienced technicians with access to a lathe.
If you decide to take a chance and restore the hub, keep in mind:
- 🔧 The cost of disassembly/assembly work often exceeds the price of a new hub.
- 🕒 Repair time - 4-6 hours (versus 1-2 hours for replacement).
- ⚠️ There is no guarantee for such repairs - there is a risk of repeated wear and tear after 5-10 thousand km.
FAQ: Frequently asked questions about the rear bearing Nissan Almera G15
Is it possible to drive with a humming bearing if there is no play?
No, even if there is no play. The hum indicates initial stage of destruction - the balls or rollers already have wear. At speeds above 80 km/h, the risk of jamming increases 3 times. The average bearing life after the appearance of a hum is 5–15 thousand km.
How long does it take to replace a bearing at a service station?
In a specialized service, work takes 1.5–2.5 hours on one side (including removing/installing the brake mechanism and checking runout). At dealer stations, the time may increase to 3–4 hours due to mandatory diagnostics before repair.
Which bearing is better - original or SKF?
Original hubs Nissan (article 40530-BM00A) last longer (100+ thousand km), but are 2–3 times more expensive. SKF VKB 3455 — optimal analogue: resource 80–100 thousand km with proper installation. The main thing is to buy from official distributors, since fakes SKF common.
Do I need to replace the bearing on both sides if only one is humming?
Not necessarily. On Almera G15 The rear bearings wear unevenly. If the second bearing has no play and does not get hot, you can leave it. However, if the car's mileage exceeds 150 thousand km, it is recommended to replace both - the second one may fail in the next 20-30 thousand km.
What happens if you don't tighten the hub nut?
Shortage leads to the appearance of play and accelerated bearing wear. After 1–2 thousand km you will hear a hum, and after 10 thousand km vibration may appear. In addition, loose tightening increases the risk self-unscrewing nuts on a rough road.
