The wheel bearing is one of the most loaded components of the chassis Nissan Almera N16, and its wear can lead to serious consequences: from an unpleasant hum at speed to complete blocking of the wheel. Owners of this model are often faced with the need to replace the bearing at mileages of 80,000 to 120,000 km, but in Russian conditions (bad roads, aggressive driving style) the service life can be reduced to 50,000–60,000 km. In this article we will look at how diagnose the problem yourself, choose a high-quality bearing and replace it without mistakes, which even experienced craftsmen often make.
Feature Almera N16 (2000–2006) in that the hub design is different from later models Nissan. For example, on the front axle the bearing is assembled with the hub, and on the rear axle it is separate (depending on the year of manufacture and configuration). This affects the complexity of the work and the cost of repairs. We will consider both options and also give recommendations on selection of analogues (including budget and premium brands) and tools that will simplify the process.
Signs of a wheel bearing failure on a Nissan Almera N16
The first signal about problems with the bearing is extraneous sounds when moving. However, many car owners confuse them with noise from tires or transmission. To accurately diagnose the problem, pay attention to the following symptoms:
- 🔊 Hum or howl on the wheel side, which intensifies as speed increases (especially noticeable at speeds of 60–90 km/h). The sound may disappear when the steering wheel is turned to one side - this is a key sign.
- 🔄 Vibration on the steering wheel or body, which does not depend on wheel balancing. It appears more often when driving on a flat road.
- 🚗 Wheel play, which is felt when swinging it with your hands in a vertical plane (checked on a jack).
- 🔥 Hub overheating after a trip - if you touch the wheel rim after stopping, the faulty side will be noticeably hotter.
On Nissan Almera N16 there is one peculiarity: rear wheel bearing wear often appears only when driving in reverse (a crunching or grinding sound appears). This is due to the design of the unit and load distribution. If you notice such a symptom, do not delay diagnosis - on this model the rear bearing fails less often, but its jamming can lead to an accident.
⚠️ Attention: On Almera N16 With ABS, the wheel speed sensor is attached to the hub. If the bearing wears too much, it may become damaged, which will lead to an error. C1130 (ABS sensor malfunction) on the dashboard. In this case, it will be necessary to replace not only the bearing, but also the sensor.
For an accurate diagnosis, jack up the car and spin the wheel by hand. If you hear a crunching sound, grinding noise, or feel uneven rotation, the bearing requires replacement. Also check the play: grab the wheel at the 3 and 9 o'clock positions and wiggle it. Play of more than 0.5 mm is a critical sign.

When choosing a bearing for Almera N16 pay attention to complete set:
- 🔧 For the front axle, the bearing is assembled with the hub (article number
40520-9M000). Some analogues (for example, NTN) are sold separately - in this case pressing will be required. - 🔄 For the rear axle, the bearing can be separate (article number
40520-4M000) or assembled with the hub (depending on the year of manufacture). Check this before purchasing! - 🛡️ Check availability protective covers - cheap analogues often do not have them, which shortens their service life.
⚠️ Attention: On Almera N16 with enginesQG15DEAndQG18DE(1.5 and 1.8 l) different wheel bearings are used! Check compatibility by VIN code or catalog Nissan. An error will result in incorrect fit and rapid wear.
Before purchasing a bearing, check it for grease. Quality products (eg NTN or Koyo) have a thick grease with a metallic tint. If the lubricant is liquid or there is little of it, it is a fake or defective.
Tools and materials for replacing the wheel bearing
Replacing the bearing with Nissan Almera N16 requires not only skills, but also special tools. Without it, the risk of damaging the hub or bearing increases significantly. Here's a complete list of what you'll need:
- 🔧 Set of sockets and keys: a 30 mm socket (for the hub nut), 17 mm, 19 mm and Torx is required
T30(for ABS sensor). - 🔨 Wheel Bearing Puller (For example, Hazet 4962-1 or equivalent). Without it, pressing out the bearing may damage the seat.
- 🔥 Gas burner or hair dryer — to heat the hub during pressing (facilitates the process).
- 🛠️ Press or powerful vice (if the bearing is separate from the hub).
- 🧲 Torque wrench — for correct tightening of the hub nut (torque 180–220 Nm).
- 🔩 WD-40 or similar penetrating lubricant - for unscrewing stuck bolts.
- 🧴 Lithium grease (For example, Molykote BR2 Plus) - for processing seats.
If you plan to replace the bearing and hub assembly (which is easier), additionally prepare:
- 🔧 Ratchet wrench with extension - for ease of unscrewing the hub mounting bolts.
- 📏 Vernier caliper — to check the runout of the new hub (tolerance no more than 0.05 mm).
Critical: On the Nissan Almera N16, the hub nut has a left-hand thread on the right side and a right-hand thread on the left! This often causes the thread to break if unscrewed incorrectly. Before starting work, make sure that you turn the key in the correct direction (on the right side - counterclockwise, on the left - clockwise).
☑️ Preparing to replace the bearing
Step-by-step instructions for replacing the front wheel bearing
Replacing the front bearing with Almera N16 more difficult than the rear one, due to the need to dismantle the brake disc and strut. We will break the process down into steps indicating key nuances, which are often missed in standard instructions.
Step 1: Removing the wheel and brake mechanism
1. Loosen the hub nut with the car stationary (you will need a 30 mm socket and a lever of at least 50 cm).
2. Raise the car on a jack, remove the wheel and unscrew the brake caliper (17 mm bolts). Hang the caliper on a wire to avoid damaging the brake hose.
3. Remove the brake rotor (light tapping with a hammer through a wooden spacer may be required).
Step 2: Removing the Hub and Bearing
1. Unscrew the bolts securing the hub to the steering knuckle (3 bolts of 19 mm). If the bolts are stuck, use WD-40 and heat.
2. Remove the hub with bearing. If the bearing comes separately, you will need a puller to press it out. On Almera N16 The method of “knocking out” the old bearing through a mandrel is often used, but this is risky - you can damage the seat.
3. Clean the seat from rust and old grease. Check the condition of the oil seal - if it is worn out, replace it.
How to press out a bearing without a puller?
If you don't have a puller, you can use the old hub as a mandrel. Place it on the new bearing and knock it out evenly with a hammer, moving the mandrel in a circle. However, this method requires caution - if it is misaligned, the bearing may jam.
Step 3: Install the New Bearing
1. If the bearing comes separately, press it into the hub using a press or vice. Preheat the hub with a hair dryer (up to 100–120°C) - this will make the process easier. Do not use a hammer! Impacts may damage the clip.
2. Apply a thin layer of lithium grease to the seat and installed bearing.
3. Install the hub onto the steering knuckle and tighten the fastening bolts (torque 80–100 Nm).
Step 4: Assembling and tightening
1. Install the brake disc and caliper. Tighten the hub nut with a torque wrench (torque 180–220 Nm). On Almera N16, overtightening the hub nut leads to premature wear of the bearing, and undertightening leads to play.
2. Bleed the brakes (if you removed the caliper) and check for any play in the wheel.
⚠️ Attention: After replacing the bearing with Almera N16 Be sure to check the wheel alignment angles! Even a slight shift of the hub can disrupt the suspension geometry.
When replacing the front bearing on a Nissan Almera N16, be sure to check the condition of the ball joint and steering tip. Their wear may masquerade as symptoms of a faulty bearing.
Replacing the rear wheel bearing: features and differences
Rear bearing on Almera N16 changes less frequently than the front, but the process has its own nuances. The main difference is the absence of a steering knuckle, which makes access easier. However, on some versions (for example, with ABS), you will need to be careful when working with the speed sensor.
Main stages:
- Remove the wheel and brake drum (or disc if disc brakes are installed).
- Unscrew the hub nut (the tightening torque is the same - 180–220 Nm, but the thread is standard, without a “reverse” on one side).
- Remove the hub from the axle. If the bearing comes separately, press it out with a puller.
- Install a new bearing (when pressing, use a mandrel to avoid damaging the race).
- Reassemble the assembly in reverse order. Please note brake drum alignment — if it is installed crookedly, there will be a beat when braking.
On the rear axle Almera N16 a common problem with sticking of the hub to the axle. If it does not come off, use a puller or carefully knock it down with a hammer through a wooden spacer. Don't hit the axle! - this may damage the thread.
If your car is equipped with ABS, after replacing the bearing, check the gap between the sensor and the tone ring (should be 0.5-1 mm). If the hub is installed incorrectly, the sensor may touch the ring, which will lead to its failure.
Common replacement mistakes and how to avoid them
Even experienced craftsmen make mistakes when replacing wheel bearings with Nissan Almera N16. Here are the most common ones and ways to prevent them:
- 🔧 Improper torque of the hub nut. Consequences: play or overheating of the bearing. Always use a torque wrench!
- 🔥 Bearing overheating during pressing. If you heat the hub with an open flame (burner), you can damage the seal. Use a hair dryer.
- 🛠️ Using a hammer to press in. This leads to microcracks in the bearing race. Only a press or vice!
- 🚗 Ignoring play check after replacement. Even a new bearing can have play if installed incorrectly.
- 🔄 Forgetting to check the ABS sensor. On Almera N16 it is attached to the hub and can be damaged during removal.
Another common mistake is saving on lubrication. Many people install the bearing “dry”, which reduces its service life by 2–3 times. Always apply a thin layer of lithium grease to the bearing seats and race.
⚠️ Attention: On Almera N16 With a mileage of more than 150,000 km, the bearing seat in the hub often wears out. If you notice wear or corrosion, it is better to replace the hub along with the bearing.
Replacement cost: yourself vs service
Wheel bearing replacement cost Nissan Almera N16 depends on several factors: the type of bearing (original or analogue), the need to replace the hub, and the region. The table below shows estimated costs:
| Type of work | Cost of spare parts, ₽ | Cost of service work, ₽ | Total, ₽ |
|---|---|---|---|
| Replacing the front bearing (original) | 4 500–6 000 | 2 000–3 500 | 6 500–9 500 |
| Replacing the front bearing (NTN) | 2 800–3 500 | 2 000–3 500 | 4 800–7 000 |
| Replacing the rear bearing (original) | 3 500–5 000 | 1 500–2 500 | 5 000–7 500 |
| Replacement bearing + hub (set) | 7 000–10 000 | 3 000–4 500 | 10 000–14 500 |
Replacing it yourself will save on work, but will require tools. If you don’t have a puller or press, renting the equipment will cost 500–1,000 rubles. Also consider hidden costs:
- 🔧 Buying a new hub nut (about 200 ₽) - it’s disposable!
- 🛡️ Replacement of the oil seal (150-300 ₽), if the old one is worn out.
- 🚗 Wheel alignment adjustment (RUB 1,000–1,500) after replacing the front bearing.
The service work will be cheaper if you change both bearings at the same time (many workshops give a discount). However, there is a risk of running into unscrupulous craftsmen who:
- They will install a cheap analogue instead of the original.
- They will not check the play after replacement.
- The hub nut tightening torque is not observed.
If you decide to contact the service, choose specialized centers according to Nissan or verified workshops with a guarantee on work.
FAQ: Frequently asked questions about replacing wheel bearings on Almera N16
Is it possible to drive with a humming bearing?
It’s possible for a short term (1-2 weeks), but it’s not worth the risk. On Almera N16 a worn bearing can seize at speed, causing loss of control. It is especially dangerous to ignore crunch when turning - this is a sign of destruction of the separator.
What is the service life of the new bearing?
When installed and used correctly:
- Original or NTN/Koyo: 80,000–120,000 km.
- Budget analogues (FAG, SNL): 40,000–60,000 km.
Service life will be shortened by off-road driving, frequent overheating of the brakes, or improper tightening of the nut.
Do the bearings need to be replaced on both sides?
Not required, but recommended if the vehicle's mileage exceeds 100,000 km. On Almera N16 The rear bearings wear more evenly, so they can be replaced in pairs. Anterior - only if there are symptoms on the second side.
What should I do if there is still a hum after replacement?
Possible reasons:
- Incorrect bearing pressing (misalignment).
- Worn seat in the hub.
- Damage to the ABS sensor or tone ring.
- Loose hub nut.
Return to diagnostics immediately - driving with such a defect is dangerous!
Is it possible to lubricate a bearing without replacing it?
Technically possible, but Almera N16 this is ineffective. The bearing here is a closed type, and lubricant will not penetrate into the cage. Temporary solution - flushing and lubrication seat, but this will extend the life of the node by a maximum of 5,000–10,000 km.
