The wheel bearing is one of the most loaded components of the chassis Nissan Almera N15, and its wear can lead to serious consequences: from an unpleasant hum at speed to complete wheel locking. Owners of this model are often faced with the need to replace the bearing already on the run. 80–120 thousand km, especially if the car was operated on Russian roads with their potholes and temperature changes.
In car services for replacing a wheel bearing with Almera N15 ask from 3,000 to 6,000 rubles (depending on the region and complexity of the work). However, if you have a minimum set of tools and patience, you can perform this procedure yourself, saving up to 70% cost. In this article we will analyze the entire process from diagnostics to final assembly, point out common errors and give recommendations on the selection of spare parts.
Signs of a wheel bearing failure on a Nissan Almera N15
The first symptoms of bearing wear are often ignored because they develop gradually. However, delay can lead to wheel jamming while driving - and this is a direct threat to security. Pay attention to the following signals:
- 🔊 Hum or howl on the wheel side, which intensifies during acceleration. At an early stage, the noise may disappear when turning (due to load redistribution).
- 🌀 Vibration on the steering wheel or body, especially noticeable at speeds 60–90 km/h. Often confused with wheel imbalance, but the bearing gives a more “ragged” vibration.
- 🔄 Wheel play when swinging it with your hands in a vertical plane (checked on a jack). Even minimal play is a reason for replacement.
- 🔥 Hub overheating. After the ride, touch the center of the wheel (carefully!): if the rim is hot and the hub burns, the bearing is working with increased friction.
On Nissan Almera N15 The rear wheel bearing fails less often than the front one, but its diagnosis is complicated by the fact that the hum can be masked by noise from the gearbox or main gear. To accurately check the rear bearing you will need jack up both sides and compare the play and noise when the wheels rotate.
⚠️ Attention: If while driving there is metallic grinding or the wheel starts to “slip” - stop immediately! These are the signs destruction of the bearing cage, and further driving may result in an accident.

What tools and spare parts will be needed
To replace the wheel bearing with Almera N15 You don’t need specialized equipment, but you can’t do without some tools. Here's the full list:
| Category | Name | Notes |
|---|---|---|
| Tools | Jack and stops | Preferably a hydraulic jack with a lifting capacity of at least 2 tons |
| Tools | Socket heads 17 mm, 19 mm, 30 mm |
To unscrew the hub nut you will need a socket 30 mm with extension |
| Tools | Wheel bearing puller | You can rent or make a homemade one from old nuts |
| Spare parts | Wheel bearing | Original Nissan 40520-4M000 or analogues: SKF VKBA 3583, NTN 4T-40520 |
| Consumables | Lubrication Litol-24 or Molykote BR2 Plus | For machining seats and new bearings |
When choosing a bearing, pay attention to country of origin. Original Japanese bearings (Nissan or NTN) last longer than their Chinese counterparts, but their price is higher by 30–50%. If your budget is limited, the best option is SKF or FAG European production.
⚠️ Attention: Do not buy bearings disassembled (balls + races separately)! On Almera N15 is installed only non-separable double row bearing — an attempt to assemble it from separate parts will lead to rapid failure.

Step-by-step instructions for replacing the front wheel bearing
Replacement process on the front axle Nissan Almera N15 takes 2–3 hours at the first experience. The main difficulty is removing the old bearing race, which often “sticks” to the hub. Follow the instructions:
- Removing the wheel and brake disc.
After jacking up the car, remove the wheel, then unscrew the two brake caliper bolts (head
17 mm) and hang it on a wire so as not to damage the hose. Next, remove the brake disc - it may be tight, so you will need a rubber mallet. - Unscrewing the hub nut.
This is the most crucial moment. The hub nut is tightly tightened 200–250 Nm, so you will need a powerful wrench or extension pipe. If the nut does not budge, use a penetrating lubricant. WD-40 and let it run for 10-15 minutes. On some versions of Almera N15, the nut has a left-hand thread - check this before unscrewing!
- Removing the hub.
After unscrewing the nut, remove the washer and press out the hub using a puller. If it is not there, you can carefully knock the hub with a hammer through a wooden spacer, but this is risky - you can damage the seat.
- Bearing replacement.
The old bearing is removed with a puller or using a homemade device made from old nuts and studs. The new bearing is pressed in only through a mandrel, evenly loading the outer ring. Do not hit the inner ring or balls under any circumstances!
After installing the new bearing, do not forget adjust the gap (unless the bearing has built-in adjustment, as on most Almera N15, simply tighten the hub nut firmly 180–200 Nm and lock it).
Before installing a new bearing, heat it in hot water (not boiling water!) to 60–70°C - this will make pressing easier and reduce the risk of damage to the seals.
Features of replacing the rear wheel bearing
Rear bearing on Nissan Almera N15 changes less frequently, but the process is more complicated due to the design of the rear beam. Main differences:
- 🔧 The brake drum needs to be removed. If it is stuck, use a puller or gently tap it in a circle with a hammer through a wooden block.
- 🔩 The hub nut can be a star pattern
Torx E14. Prepare the appropriate key in advance. - 🔄 The rear wheel bearing often comes complete with an oil seal. When replacing, be sure to check the condition of the oil seal - if it is cracked, replace it.
On the rear axle Almera N15 the hub is often “welded” to the axle shaft. To remove it you may need three-jaw puller or even a cutting torch (as a last resort). If the axle shaft rotates along with the hub, secure it with a mounting blade through the holes in the flange.
What to do if the bearing “hums” after replacement?
If noise remains after installing a new bearing, check:
1. Correct pressing - the bearing must sit without distortion.
2. Condition of the hub seat - is there any scoring or corrosion.
3. Tightening the hub nut - it must be tightened to the correct torque (under- or over-tightening will accelerate wear).
4. The quality of the bearing itself - Chinese analogues often have play out of the box.
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing wheel bearings. Here are the most common mistakes on Nissan Almera N15:
- 🔨 Impact on the inner race of the bearing. This leads to damage to the raceways and shortens the bearing life. 2–3 times. Always use a mandrel that presses only on the outer ring.
- 🔧 Incorrect hub nut tightening torque. A weak tightening causes backlash, a strong tightening causes overheating. Optimal value for Almera N15: 180–200 Nm.
- 🛠️ Ignoring the seal. If the hub seal is worn, dirt will penetrate through it and the new bearing will quickly fail. Always replace the oil seal together with the bearing.
- 🚗 Failure to check play after assembly. After replacing, be sure to check the wheel for play by rocking it in the vertical and horizontal planes. Permissible backlash - no more 0.05 mm.
Another common mistake is saving on lubrication. Many people install the bearing “dry”, but this reduces its service life by 30–40%. Use high temperature lubricant (eg Molykote BR2 Plus) for processing the seats and the internal cavity of the hub.
On Nissan Almera N15 with ABS, the speed sensor is attached to the hub. When replacing the bearing, be sure to check the gap between the sensor and the drive disk - it should be 0.8–1.2 mm.
Cost of service work vs independent replacement
Prices for replacing a wheel bearing in car services vary depending on the region and level of the service station. The average cost in Russia looks like this:
| Type of work | Cost (RUB) | Time (hours) |
|---|---|---|
| Replacing the front bearing (1 side) | 3 000 – 4 500 | 1,5–2 |
| Rear bearing replacement (1 side) | 3 500 – 5 000 | 2–3 |
| Replacing the bearing assembly with the hub | 4 500 – 6 000 | 2–3 |
| Chassis diagnostics (checking backlash) | 500 – 1 000 | 0,5 |
If you replace it yourself, your costs will be limited to the cost of spare parts:
- Front bearing: 1,500–3,500 rub. (depending on the brand).
- Rear bearing: 2,000–4,000 rub. (often comes complete with a hub).
- Lubricant and consumables: 200–500 rub.
Thus, the savings will be 2,500–5,000 rubles. for one side. However, if you do not have experience or special tools (for example, a puller), the risk of error increases. In this case, it is better to trust the professionals.
Recommendations for extending bearing life
To ensure that the wheel bearings on your Nissan Almera N15 last longer, follow these tips:
- 🚿 Avoid deep puddles. Sudden temperature changes (hot bearing - cold water) destroy the lubricant and cause corrosion.
- 🛣️ Balance your wheels in a timely manner. The imbalance creates additional load on the bearing, accelerating its wear.
- 🔧 Check the play every 20 thousand km. Early diagnosis allows you to replace the bearing before critical wear.
- 🧴 Use quality lubricant. Cheap lubricants lose their properties when heated, which leads to “dry” friction.
If you frequently drive off-road or transport heavy loads, the bearings will wear out faster. In this case it is recommended check their condition every 10–15 thousand km and use bearings with reinforced races (for example, SKF Explorer).
FAQ: Frequently asked questions about replacing the wheel bearing on a Nissan Almera N15
Is it possible to drive with a humming bearing?
It’s possible for a short time (up to 500–1000 km), but it’s not worth the risk. The hum indicates wear on the raceways, and the bearing may seize at any moment. Driving at high speeds is especially dangerous as it can lead to loss of control.
Which bearing is better to choose: original or analogue?
Original bearings Nissan or NTN They last longer, but are more expensive. If your budget is limited, take it SKF or FAG - they are only slightly inferior in terms of resource. Avoid Chinese brands like FEBEST or GMB - their quality is unpredictable.
Do I need to replace the bearing on both sides if only one is humming?
Not necessarily. Bearings wear out independently of each other. However, if the car's mileage exceeds 150 thousand km, it is advisable to replace both bearings on the axle - the second one may soon fail.
Is it possible to replace a bearing without a puller?
Theoretically yes, but it's risky. Without a puller, it is difficult to remove the old bearing without damaging the seat in the hub. You can use an old race and a hammer to press in a new bearing, but this requires care.
What should I do if vibration appears after replacing the bearing?
The reasons may be different:
- Incorrect tightening of the hub nut (overtightened or undertightened).
- Damage to the seat in the hub during pressing.
- Wheel imbalance (check balancing).
- Defective bearing (found in cheap analogues).
Check all points and repeat replacement if necessary.
