Wheel bearing on Nissan Almera N16 - one of those parts that wears out gradually, but if critical wear occurs, it can lead to serious consequences: from wheel play to complete blocking of the hub while driving. Owners of this model are often faced with the need to replace front bearings at mileages from 80,000 to 120,000 km, but the exact period depends on operating conditions, road quality and driving style.
Unlike the rear bearings, which are Almera N16 last longer, the front ones are subject to higher loads due to the rotating mechanism and the weight of the engine. If you notice a hum when driving, vibration in the steering wheel or play in the wheel, these are direct signs that the bearing requires diagnostics. In this article we will look at how to replace the front wheel bearing yourself without resorting to the services of a service station, saving from 3,000 to 6,000 rubles.
Signs of a wheel bearing failure on a Nissan Almera N16
The first symptoms of bearing wear are often ignored by drivers, as they appear gradually. However, delay can result not only in expensive repairs, but also in an accident. Pay attention to the following signals:
- 🔊 Hum or howl on the side of the front wheel, which intensifies when accelerating (especially noticeable at speeds above 60 km/h). The sound may change when you turn the steering wheel - this is due to load redistribution.
- 🌀 Vibration on the steering wheel or body, which does not disappear after wheel balancing. Most often, vibration is felt when driving on a flat road.
- 🔄 Wheel play when rocking it in a vertical plane (checked on a jack). Even minimal play is a reason for replacement.
- 🔥 Hub overheating after the trip. If after stopping the wheel is hot and the brake discs are cold, this is a sign of friction in the bearing.
On Nissan Almera N16 with engines QG15DE And QG18DE bearing wear often manifests itself asymmetrically - for example, the left one may “howl” more than the right one due to the difference in load when turning. If these symptoms are ignored, the bearing may fail, leading to wheel seizure or CV joint damage.
⚠️ Attention! If while driving there is metallic grinding or the wheel starts to “slip” - stop immediately. These are signs of complete bearing failure. Further movement is unsafe!
Tools and materials for replacement
To replace the front wheel bearing with Almera N16 you will need a specialized tool. Some operations (for example, removing a hub) are almost impossible to perform without it. Here's the full list:
| Tool/material | Purpose | Note |
|---|---|---|
| Jack and stops | Lifting and securing the car | Use only reliable supports! |
| Wheel bearing puller | Removing and installing the bearing | Can be rented or bought (from RUB 1,500) |
| Sockets (17, 19, 30 mm) | Unscrewing the hub nut and bolts | 30 mm socket - for CV joint nut |
| Torque wrench | Torque the hub nut to the correct torque | moment for Almera N16 — 230–250 Nm |
| Hammer and drift | Carefully knocking out the hub | Use a copper or aluminum drift |
Also prepare new parts:
- 🔧 Wheel bearing (original -
Nissan 40520-4M000, analogues - SKF VKBA 3643, NTN 4T-40520). - 🔩 New hub nut (disposable, original -
Nissan 40526-4M000). - 🛠️ Bearing grease (For example, LIQUI MOLY LM 50).
⚠️ Attention! Do not use used bearings or cheap analogues without a brand. On Almera N16 this often leads to repeated replacement after 10–20 thousand km.
- Jack and heads
- Bearing puller
- Torque wrench
- None of the above
Step-by-step instructions for replacing a bearing
The process of replacing the front wheel bearing with Nissan Almera N16 takes 3–5 hours if you have experience. If this is your first time doing this, be patient and follow the instructions strictly point by point.
1. Preparing the car
Place the car on a level surface, tighten the handbrake and place chocks under the rear wheels. Loosen the front wheel nuts, then jack up the car and remove the wheel. For reliability, place additional support under the threshold.
2. Removing the brake disc and caliper
Unscrew the two bolts securing the caliper (17 mm head) and hang it on a wire to the spring so as not to damage the brake hose. Remove the brake disc - it may “stick” to the hub, so gently tap it with a hammer through a wooden spacer.
3. Removing the hub and CV joint
Unscrew the hub nut (30 mm socket) - it is tightened with a large torque, so you may need an extension for the wrench. Then disconnect the steering linkage and ball joint. Press the CV joint out of the hub using a puller or gentle blows of a hammer.

4. Bearing replacement
Using a puller, remove the old bearing from the hub. Clean the seat from dirt and rust. Press the new bearing evenly, without distortions. On Almera N16 the bearing is installed only on one side - there must be a technological groove on the side of the ABS sensor.
After installing the bearing, apply grease to the running surfaces and install a new hub nut. Tighten it with a torque wrench to a torque of 230–250 Nm.
If the bearing does not move when pressed, check whether it is warped. Use a mandrel that puts even pressure on the outer ring, not the balls!
5. Assembly and testing
Reinstall the brake disc, caliper and wheel. Lower the car and check the wheel play. Drive 5–10 km and listen to outside noises. If the hum has disappeared and the wheel rotates freely, the replacement was successful.
After replacing the bearing, be sure to check the wheel alignment! Even a slight displacement of the hub can disrupt the wheel alignment angles.
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 of them:
- 🔧 Retightening the hub nut - leads to overheating of the bearing. Always use a torque wrench!
- 🛠️ Installing a bearing without lubrication - accelerates wear. Apply lubricant to both rings.
- 🌀 Ignoring play in the CV joint - if the CV joint is worn out, vibration will quickly destroy the new bearing.
- 🔥 Pressing the bearing in with hammer blows - this deforms the rings. Use a puller only.
Another typical mistake is skimping on bearing quality. Cheap analogues (for example, without a brand) often have poor-quality heat treatment of the metal, which leads to delamination of the rings after 20–30 thousand km. On Almera N16 optimal choice - SKF or NTN.
⚠️ Attention! If after replacing the bearing there is clicking sound when turning the steering wheel, check the tightness of the ball joint and steering joint bolts. This is not related to the bearing, but is often confused with a bearing failure.
Cost of service replacement vs self-repair
Front wheel bearing replacement cost Nissan Almera N16 in services varies depending on the region and service station level:
| Service | Cost (RUB) | Note |
|---|---|---|
| Bearing replacement (1 side) | 3 000 – 5 000 | Excluding spare parts |
| Chassis diagnostics | 500 – 1 500 | Often included in the cost of repairs |
Original bearing Nissan 40520-4M000 |
2 500 – 3 500 | Analogs are 30–50% cheaper |
| Lubricant and small things | 300 – 800 | Hub nut, cleaner |
If you replace it yourself, your expenses will be limited to the purchase of a bearing, nut and lubricant - a total of about 3,000–4,000 rubles. However, if you do not have a puller or torque wrench, purchasing or renting them will increase your budget by 2,000–3,000 rubles.
Is it profitable to do it yourself? Yes, if:
- 🔧 You have experience working with chassis.
- 🛠️ There is the necessary tool (or the opportunity to rent it).
- ⏳ You are ready to spend 4-5 hours on work.
Contact the service if:
- 🚗 No experience with suspension.
- 🔩 There is no puller for bearings.
- 📏 You need a guarantee for work (most service stations give 6-12 months).
Tips for Extending Bearing Life
Even the highest quality bearing will not last long if you do not follow simple operating rules. Here's what will help increase its resource:
- 🚿 Avoid deep puddles - water washes the lubricant out of the bearing, accelerating corrosion.
- 🛣️ Balance your wheels in a timely manner — imbalance creates additional stress.
- 🔧 Check wheel play every 20,000 km (just pump the wheel on a jack).
- 🌀 Don't Ignore Suspension Knocks — worn ball or steering ends overload the bearing.
On Nissan Almera N16 With automatic transmissions, bearings wear out faster due to the higher weight of the vehicle and the characteristics of load distribution. If you operate the car in the city with frequent acceleration and braking, check the condition of the bearings every 15,000–20,000 km.
What to do if the bearing hums 5,000 km after replacement?
If the new bearing begins to make noise shortly after installation, the reasons may be as follows:
1. **Incorrect press-fit** - the bearing is installed skewed.
2. **Lack of lubrication** - some “masters” forget to lubricate the working surfaces.
3. **Part defects** - especially true for cheap analogues.
4. **Overtightened hub nut** - leads to overheating.
In this case, it is necessary to re-dismantle the bearing, inspect it for damage and reinstall it in compliance with all rules.
FAQ: Frequently asked questions about replacing the wheel bearing on a Nissan Almera N16
Is it possible to drive with a running bearing?
No! Even a small amount of play indicates critical wear. When driving at high speed, the bearing may collapse, which will lead to the wheel jamming. The maximum that can be done is to drive to the service station at a speed of no more than 40 km/h, avoiding sharp turns.
Which bearing is better to choose: original or analogue?
Original bearing Nissan 40520-4M000 guarantees compatibility, but costs more. High-quality analogues - SKF VKBA 3643 or NTN 4T-40520 - no worse in terms of resource, but 30–40% cheaper. Avoid no-name brands!
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 150,000 km, it is advisable to replace both - the second one may require replacement.
Is it possible to replace a bearing without a puller?
Theoretically yes, but it's risky. Without a puller, there is a high probability of damaging the seat in the hub or installing the bearing crookedly. If you don’t have a puller, it’s better to contact service.
What happens if you don't tighten the hub nut?
A loose nut leads to wheel play and accelerated bearing wear. When driving, this will manifest itself as vibration in the steering wheel and a hum. Always use a torque wrench!
