Wheel hub for Nissan Almera G15: how to choose, replace and avoid mistakes

Nissan Almera G15 is a popular sedan that is valued for its reliability and unpretentiousness. But even such machines have weak points, and one of them is wheel bearings. If you hear a hum when driving or notice play in the wheel, most likely the problem is in the hub. In this article we will look at how to correctly diagnose a malfunction, choose a high-quality spare part (original or analogue) and replace the hub yourself - taking into account the features Almera G15 2013–2018.

It is important to understand that the hub is not only a bearing, but also a complex assembly that includes an ABS sensor, seats for the brake disc and mounts to the steering knuckle. On Almera G15 The front and rear hubs have different designs, so the approach to replacing them will be different. We will look at both options, and also give tips on how to save on repairs without losing quality.

Signs of a hub failure on a Nissan Almera G15

The first symptoms of wheel bearing wear are often ignored until the problem becomes critical. On Almera G15 Symptoms may appear differently depending on mileage and operating conditions. Here's what you should pay attention to:

• 🔊 Hum or howl on the wheel side, which intensifies during acceleration. In the early stages, the noise may only appear at speeds above 60 km/h.
• 🌀 Wheel play, which is felt when swinging it with your hands in a vertical plane (checked on a jack).
• 🚨 Vibration on the steering wheel or body, especially when braking - this may indicate damage to both the hub and the brake disc.
• 🔴 Hot wheel rim after the trip (be careful - do not touch immediately after stopping!). Overheating indicates friction in the bearing.
• 🛑 ABS triggers for no reason - If the ABS sensor is built into the hub, its damage may cause false signals.

On Nissan Almera G15 With a mileage of more than 100,000 km, wheel bearings often fail due to natural wear. However, accelerated wear can be caused by aggressive driving in potholes, improper installation, or the use of low-quality spare parts. Feature of the model: on the front axle, the hub is integrated with an ABS sensor, so when replacing it, it may be necessary to reflash errors in the ECU.

⚠️ Attention! If you ignore the noise of the bearing, it may seize while driving. On Almera G15 this is fraught with loss of control, especially at high speed. At the first sign of a malfunction, check the unit at a service station or yourself.

Original vs analogs: what to choose for Almera G15

When replacing the hub with Nissan Almera G15 The owner is faced with a choice: buy an original spare part or an analogue. The original hubs are produced by the company NTN or Koyo (supplier for the Nissan assembly line). Their articles:

• 🔧 Front hub (with ABS sensor): 40520-BM40A or 40520-4M000 (depending on the year of manufacture).
• 🔧 Rear hub: 40520-JM00A (without ABS sensor).

The cost of original parts starts from 8,000 rubles for the front and 5,000 rubles for the rear. However, there are worthy analogues on the market that will cost less:

Brand	Article (front)	Article (rear)	Price, rub.	Features
SKF	VKBA 3603	VKBA 3510	4 500 – 6 000	High quality bearings, but ABS sensor may require work.
Febi	22610	22608	3 800 – 5 200	Good price/quality ratio, but there are fakes.
SNR	R154.50	R154.10	4 200 – 5 500	French brand, bearings with extended life.
GMB	710-1040	710-1030	3 500 – 4 800	A budget option, but the build quality may vary in different batches.

When choosing an analogue, pay attention to:

• 🔍 Availability of ABS sensor (on the front axle it must be compatible with the ECU Almera G15).
• 🛠️ Complete set - Some kits lack mounting bolts or retaining rings.
• 📦 Packaging — original parts and high-quality analogues have holograms and protective stickers.

Step-by-step replacement of the front hub on Almera G15

Replacing the front hub with Nissan Almera G15 more difficult than the rear one, due to the integrated ABS sensor and the need to disassemble the brake mechanism. To work you will need:

• 🔧 Set of sockets and keys (for 17, 19, 21).
• 🔧 Puller for wheel bearings (can be rented).
• 🔧 Jack and stops.
• 🔧 Torque wrench (for tightening with the correct torque).
• 🔧 WD-40 or a similar composition for unscrewing stuck bolts.

Step by step instructions:

1. Preparation: Secure the vehicle on a level surface, engage the gear and place chocks under the rear wheels. Loosen the wheel bolts, but do not remove it completely.
2. Removing the wheel and brake mechanism:
   • Jack up the car and remove the wheel.
   • Unscrew the two bolts securing the brake caliper (17mm wrench) and hang it on a wire without disconnecting the hose.
   • Remove the brake rotor (light tapping with a hammer through a wooden spacer may be required).
3. Disconnecting the hub:
   • Disconnect the ABS sensor connector (be careful not to damage the wires!).
   • Unscrew the hub nut (30 or 32 wrench, tightening torque - 180–200 Nm).
   • Press out the hub using a puller or carefully knock it down with a hammer through a mandrel.
4. Installing a new hub:
   • Clean the seat from dirt and rust.
   • Install the new hub by tightening the nut with a torque wrench (torque - 180 Nm).
   • Connect the ABS sensor and check the circuit with a multimeter (resistance should be 800–1400 ohms).

Assembly: Install the brake disc, caliper and wheel. Bleed the brakes and check ABS operation.

⚠️ Attention! On Almera G15 with the ESP system after replacing the hub an error may light up C1130 (ABS sensor malfunction). To reset it, you will need a diagnostic scanner (for example, Launch X431) or resetting the negative terminal of the battery for 10 minutes. If the error remains, check the polarity of the sensor connection.

Replacing the rear hub: nuances and differences from the front

Rear hub on Nissan Almera G15 easier to replace, since it does not have an ABS sensor (it is located separately on the lever). However, there are some peculiarities here:

• 🔧 No integrated sensor simplifies the process, but requires caution when working with the brake drum.
• 🔧 Fastening bolts hubs often stick to the axle - they need to be treated with WD-40 in advance.
• 🔧 Bearing in the rear hub it is less loaded, so it lasts longer (resource - 150,000+ km).

Replacement algorithm:

1. Remove the wheel and brake drum (you may need to unscrew the guide pins).
2. Unscrew the 4 bolts securing the hub to the axle (17 wrench).
3. Remove the hub using a puller or carefully knock it down with a hammer.
4. Install the new hub by tightening the bolts crosswise to a torque of 80–100 Nm.
5. Reassemble the brake mechanism and check for any play.

Important point: on the rear axle Almera G15 the hub often “sticks” to the axle due to corrosion. If it cannot be removed with a puller, do not hit it directly - use a wooden spacer to avoid damaging the new bearing.

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when working with hubs Nissan Almera G15. Here are the most common ones and how to prevent them:

• 🔨 Using an old hub nut. It becomes deformed when tightened and may turn. Always use a new nut (article - 40506-JA00A).
• 🔧 Incorrect tightening torque. Over-tightening leads to premature wear of the bearing, and weak tightening leads to play. For the front hub the torque should be 180–200 Nm, for the rear - 80–100 Nm.
• 🛠️ ABS sensor damage during installation. Check the resistance of the sensor with a multimeter before and after installation (the norm is 800–1400 Ohms).
• 🚗 Ignoring wheel alignment. After replacing the front hub necessarily do a wheel alignment, as the suspension geometry changes.
• 🔥 Bearing overheating during pressing. Do not use a gas torch - heat the hub in the oven to 100°C or use a special press-fitting lubricant.

Another typical problem is buying counterfeits. There are many counterfeit branded hubs on the market SKF or NTN. To avoid being scammed:

• Check the holograms on the packaging.
• Compare the weight of the part (the original weighs 10–15% more than the fake).
• Buy from authorized dealers or trusted suppliers (for example, Exist.ru, Autodoc).

How to distinguish an original NTN hub from a fake?

Original hub NTN for Almera G15 has:

1. Logo NTN or Nissan stamped on the body (not a sticker!).

2. Marking of the article on the end.

3. Factory lubricant Molykote (greenish tint) inside the bearing.

4. Kit includes a new nut and snap ring.

Counterfeits often have rough metal finish and dull color.

Cost of service replacement vs self-repair

If you are not confident in your abilities, replacing the hub with Nissan Almera G15 It's better to leave it to professionals. However, prices for services can vary greatly:

Type of work	Cost (RUB)	Time (hours)	Notes
Replacing the front hub	3 500 – 5 000	1.5–2	Includes brake removal/installation and ABS testing.
Rear hub replacement	2 500 – 3 500	1–1.5	Easier, but may require pressing.
ABS diagnostics after replacement	1 000 – 1 500	0.5	If the malfunction indicator comes on.
Wheel alignment (front axle)	1 500 – 2 000	0.5	Mandatory after replacing the front hub.

Replacing it yourself will cost less, but will require tools and time. The savings will be:

• 💰 2,000–3,000 rubles on the front axle.
• 💰 1,500–2,000 rubles on the rear axle.

However, consider the hidden costs:

• Rental of a puller - 500–1,000 rubles.
• Purchase of a torque wrench (if not available) - from 2,000 rubles.
• Possible errors leading to repeated repairs.

Prevention: how to extend the life of hubs on Almera G15

Wheel bearing life for Nissan Almera G15 depends not only on the quality of the parts, but also on the driving style and care. Here are some tips to help avoid premature wear:

• 🚗 Avoid sharp impacts on wheels (potholes, curbs). The bearing does not like axial loads.
• 🔧 Check play regularly wheels (every 20,000 km). Early diagnosis will save on repairs.
• 🛠️ Monitor the condition of the anthers. If they are damaged, dirt and moisture enter the bearing.
• 🌀 Don't ignore wheel imbalance. Runout when driving accelerates hub wear.
• 🔥 Don't overload the car. Almera G15 not designed for constant driving with excess load capacity.

Also pay attention to the quality of the roads. If you often drive on dirt roads or broken asphalt, check your hubs every 15,000 km. In urban conditions, diagnostics once every 30,000 km is sufficient.

If you live in a region with aggressive winters (salt, reagents), treat the hub bolts and seats with anti-corrosion compounds. This will prevent parts from sticking and make future repairs easier.

FAQ: Frequently asked questions about Nissan Almera G15 hubs

Is it possible to drive with a humming hub?

Short-term - yes, but no more than 1,000–2,000 km. Further, the risk of bearing jamming increases sharply. On Almera G15 this is especially dangerous due to the light suspension, which does not smooth out impacts when the wheel locks.

What is the service life of the original hubs?

Under normal use, the original hubs NTN/Koyo serve 100,000–150,000 km. Analogues SKF or SNR have a resource of 80,000–120,000 km. The lifespan is shortened when driving on bad roads or frequent overloads.

Does the hub assembly need to be replaced or can just the bearing be replaced?

On Almera G15 The hub comes complete with a bearing, and Nissan does not officially provide for replacing just the bearing. However, some workshops offer re-pressing. This is cheaper, but unreliable - the new bearing may not fit tightly, which will lead to play.

Why does the wheel get hot after replacing the hub?

The reasons may be as follows:

• The hub nut is tightened too tightly (the torque is exceeded).
• The bearing boot is damaged (dirt has entered).
• Poor quality bearing (defective or counterfeit).
• Stuck brake caliper (check its operation).

Stop immediately and check the temperature of the other tires. If only one heats up, the problem is in the hub or brakes.

Can I install a hub from another Nissan model?

Theoretically on Almera G15 fit hubs from Nissan Note (E12) or Micra (K13), but there are nuances:

• Front hub from Note has a different ABS sensor part number (40520-JM00A instead of 40520-BM40A).
• The rear hub may not fit the diameter of the mounting hole.
• Even if the part physically fits, there may be problems with ABS.

It’s better not to experiment and take hubs specifically for Almera G15.
