The wheel bearing is one of those components that many car owners Nissan Almera G15 they notice only when it is already “howling” on every bump. Meanwhile, ignoring the first signs of wear can lead not only to expensive repairs, but also to loss of control of the car at high speed. In this article we will look at how to recognize the problem in time, which bearings are suitable for Almera G15 (including restyled versions 2016–2019), and whether it is possible to cope with the replacement without visiting a service station.
Feature Almera G15 the fact that the design of the front and rear suspension here is simpler than that of the “older” models Nissan (For example, Qashqai or X-Trail). This simplifies access to the hub, but requires precision when selecting spare parts - original bearings from NTN or Koyo They last longer than analogues, but also cost 30–50% more. We analyzed owner reviews and service manuals to collect up-to-date information without fluff and common phrases.
Signs of a bad wheel bearing Nissan Almera G15
The first signal is hum or howl, which intensifies when accelerating or cornering. However, on Almera G15 (especially with mileage over 100 thousand km) similar sounds can come from both the gearbox and CV joints. How to distinguish?
Take the test:
- 🔍 On the go: At a speed of 60–80 km/h, slightly “wiggle” the steering wheel left and right. If the noise gets louder when turning left - the problem is right bearing, and vice versa.
- 🚗 On site: lift the car with a jack and swing the wheel in a vertical plane. Play of more than 0.5 mm is a sign of critical wear.
- 🔥 Overheat: After driving, touch the hub (carefully!). If it is hotter than the other wheels, the bearing wears out.
On Almera G15 with ABS, a faulty bearing can cause false alarm of the system (the lamp on the tidy lights up periodically). This is due to the fact that the ABS sensor is built into the hub assembly, and vibrations from a worn bearing distort its signals.
⚠️ Attention: If you hear it when braking metallic grinding, it may not be a bearing, but worn pads touching the brake disc. Check their condition before diagnosing the hub!
- Only when the hum appears
- Every 20–30 thousand km
- Once a year for seasonal tire replacement
- Never checked
Which bearings are suitable for Nissan Almera G15 (2012–2019)
Original bearings for Almera G15 supplies NTN (Japan), but the assembly line also uses parts Koyo And NSK. Important: front and rear bearings are different by size and catalog numbers!
| Position | Original number | Analogs (brand + art.) | Notes |
|---|---|---|---|
| Front (right/left) | 40520-BM40A |
NTN 4T4-3006, Koyo DAC40720039, SKF VKBA 3643 |
Complete with nut |
| Rear (right/left) | 40520-4M00A |
NSK 512167, Febi 22700, SNR R155.62 |
Requires pressing |
| Hub assembly (front) | 40500-BM40A |
TRW JHB1036, Mapco 61006 |
For replacement without a puller |
It is better to choose brands among analogues SKF, NTN or Koyo — they correspond to the original in terms of the quality of steel and seals. Cheap bearings (for example, Febi or Optimal) can “walk” only 30–50 thousand km, especially when driving on bad roads.
On restyled Almera G15 (2016–2019) rear bearings became slightly larger - the number changed from 40520-4M00A on 40520-4M01A. Check your VIN before purchasing!
If you buy a bearing separately from the hub, be sure to check availability magnetic ring for ABS sensor. Some analogues do not have it, and the sensor will have to be replaced from the old bearing.
Bearing diagnostics: tools and step-by-step instructions
For an accurate diagnosis you will need:
- 🔧 Jack and stops (or lift).
- 📏 Feeler gauge for measuring play (or ruler).
- 🔊 Mechanic's stethoscope (or long screwdriver).
- 🌡️ Infrared thermometer (optional).
Verification algorithm:
- Raise the car and remove the wheel. Clean the hub from dirt.
- Rotate the dial by hand - if you hear crunching or jamming, the bearing requires replacement.
- Place a stethoscope (or a screwdriver with your ear on the handle) to the hub. When the wheel rotates extraneous noise will be clearly audible.
- Check the hub temperature after driving - overheating above 70°C indicates bearing friction.
⚠️ Attention: On Almera G15 with a mileage of more than 150 thousand km, bearing wear is often accompanied by cracks in the hub. If microcracks are visible during inspection, replace the assembly!

Step-by-step replacement of the wheel bearing with Nissan Almera G15
The process for replacing the front and rear bearings is different. Let's consider front (as a more complex option):
Tools:
- 🔧 30 mm spanner (for the hub nut).
- 🔨 Bearing puller (or press).
- 🔩 Torx T30 (for ABS sensor).
- 🧲 Magnet for bolts.
Work order:
- Remove the wheel, brake caliper (hang it on a wire, do not disconnect the hose!) and disc.
- Unscrew the hub nut (tightening torque during installation -
200–220 Nm). - Remove the ABS sensor by disconnecting the connector and unscrewing the bolt
T30. - Press out the old bearing with a puller. If it is not there, carefully knock it out with a hammer through the mandrel, hitting outer ring.
- Clean the seat from rust and lubricate. Install the new bearing by pressing it in until it stops.
- Reassemble the assembly in reverse order. Tighten the hub nut only after lowering the vehicle to the ground!
For rear bearing The algorithm is simpler - it is pressed out together with the hub. The main thing is not to damage axle shaft seal when removed.
What to do if the bearing is stuck?
If the bearing does not come out even after impacts, use penetrating lubricant (For example, WD-40 Specialist) and heat the hub with a hair dryer (not higher than 100°C). An alternative is to drill out the inner ring and crack it with a chisel.
Common replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that shorten the service life of a new bearing. That's what can't do on Almera G15:
- ❌ Hit the bearing with a hammer without a mandrel. This deforms the seating surfaces and leads to premature wear.
- ❌ Use the old hub nut. It becomes deformed when tightened - always take a new one (original number
40525-4M000). - ❌ Do not lubricate the seat. Without lubrication, the bearing may “bite” during installation.
- ❌ Tighten the hub nut on the suspended wheel. This will lead to distortion and vibration.
Another typical problem is ABS sensor damage when removed. On Almera G15 it is attached with one bolt T30, but often gets stuck. To avoid breaking the wires, pre-treat the threads Liqui Moly LM-40 and let sit for 10-15 minutes.
After replacing the bearing, be sure to check wheel alignment — even a small play in the hub could shift the wheel alignment angles.
How much does a replacement cost: prices for spare parts and labor
The cost depends on whether you are replacing the bearing separately or the hub assembly. Here are the current prices for 2026 (for Moscow and regions):
| Part/Work | Price (RUB) | Notes |
|---|---|---|
| Front bearing (NTN) | 2 500–3 200 | Lubricant included |
| Rear bearing (Koyo) | 1 800–2 400 | Without hub |
| Hub assembly (front) | 5 000–7 500 | With bearing and ABS sensor |
| Bearing replacement (STO) | 3 000–5 000 | Without cost of spare parts |
| Replacing the hub assembly | 2 500–4 000 | Easier than a separate bearing |
Replacing it yourself will cost less, but will require puller (rental at car services costs ~500 rubles/day). If you have no experience, it is better to trust the professionals - errors during pressing can lead to bearing destruction after 5–10 thousand km.
How to extend the life of a wheel bearing Almera G15
Average bearing life at Almera G15 - 80–120 thousand km, but with proper operation it can last 150+ thousand km. Here's what affects service life:
- 🛣️ Road quality: Driving through potholes and speed bumps at speeds >40 km/h reduces the service life by 30–40%.
- 🚿 Pressure washing: a stream of water that gets under the boot washes away the lubricant.
- ⚙️ Retightening the hub nut: the tightening torque should be
200–220 Nm- no more! - 🔥 Brake overheating: If after intense braking you immediately drive into a puddle, the bearing is subject to thermal shock.
Preventive measures:
- 🔧 Every 10 thousand km, check the wheel play.
- 🛠️ Once every 30 thousand km, clean the hub from dirt and renew the lubricant in the boot.
- 🚘 Avoid long drives with faulty shock absorbers - they increase the load on the bearings.
FAQ: Frequently asked questions about bearings Nissan Almera G15
Is it possible to drive with a humming bearing?
Short-term (up to 1-2 weeks) - yes, but it’s not worth the risk. At speeds above 100 km/h, a worn bearing may jam, which will lead to loss of control. At the first sign of trouble, plan a replacement.
Which bearing is better - original or analogue?
Original bearings (NTN or Koyo) last longer, but if your budget is limited, you can choose SKF or NSK. Avoid Brands Febi, Optimal and no-name - their resource rarely exceeds 50 thousand km.
Do I need to change the bearing when replacing the hub?
If the hub comes complete with a bearing (for example, 40500-BM40A), then there is no need to change it separately. If you buy a hub without a bearing, be sure to install a new one, since the old one is already worn out.
Is it possible to replace a bearing without a puller?
Theoretically, yes - using a hammer and a mandrel (for example, an old hub). But the risk of damaging the seat or the new bearing is very high. For Almera G15 It’s better to rent a puller or contact a service center.
Why did the hum remain after replacing the bearing?
Probable reasons:
- The bearing is installed skewed.
- Insufficient tightening of the hub nut.
- Worn CV joint or hub (assembly needs to be replaced).
- Dirt has gotten into the new bearing (check the boot).
