Replacing the front wheel bearing on a Nissan Almera Classic: instructions with nuances

Replacing the wheel bearing with Nissan Almera Classic (body N16) is a task that every owner of this car faces sooner or later. The front bearing here fails more often than the rear one due to increased loads on the steered axle, especially when driving on rough roads or after long-term operation without maintenance. The service asks for such work from 3 to 6 thousand rubles (depending on the region), but if you have the tools and minimal skills, you can do it yourself - saving money and gaining invaluable experience.

In this article we will look at all stages of replacement — from fault diagnosis to assembly of the unit, we will pay attention selection of quality spare parts (original vs analogues), and also we will open typical mistakesthat beginners admit. We will pay special attention unique feature of Almera Classic: on some modifications from 2006–2012, the hub and bearing are supplied separately, which complicates the selection. If you hear a hum when driving or feel wheel play, read on.

Signs of a bad wheel bearing

The first symptoms of bearing wear are often ignored until the problem becomes critical. On Nissan Almera Classic The symptoms appear gradually, but they can easily be confused with other chassis malfunctions. Here are the key signals:

• 🔊 Hum or howl on the wheel side, which intensifies during acceleration (especially at speeds of 60–90 km/h). The sound may disappear when the steering wheel is turned to one side - this indicates a specific wheel.
• 🔄 Wheel play when rocking it in a vertical plane (checked on a jack). Even a minimal gap is a reason for diagnosis.
• 🔥 Hub overheating after the trip. If after stopping the wheel is hot (your hand can’t stand it) and the brake discs are cold, the bearing is to blame.
• 🚗 Vibration on the steering wheel or body, which is not related to wheel balancing. More often appears when driving over uneven surfaces.

On Almera Classic with a mileage of more than 150 thousand km, the bearings last an average of 80–120 thousand km, but the service life depends on the driving style and the quality of the roads. Critical moment - when a hum is heard even at low speeds or a crunching sound appears when the wheel rotates. In this case, driving further is dangerous: the bearing may jam, which will lead to loss of control.

⚠️ Attention: If while driving there is metallic grinding or the wheel starts to “slip” - stop immediately! This is a sign of a damaged bearing cage. Further operation is fraught with the risk of hub breakage.

What tools and materials will be needed

To replace the front wheel bearing with Nissan Almera Classic You don't need a professional tool, but some equipment is required. Here's the full list:

Category	Name	Notes
Main tool	Jack and supports (or lift)	Minimum load capacity - 1.5 tons
Special tools	Wheel bearing puller (or press)	For Almera Classic Suitable for 72mm puller
Keys	17, 19, 30 mm heads and wrench	30 mm socket - for the hub nut (tightening torque 200–220 Nm)
Additionally	WD-40, hammer, chisel, torque wrench	WD-40 is useful for unscrewing stuck bolts
Spare parts	New bearing, retaining ring, hub nut	It is recommended to replace the hub nut with a new one

If you are planning press bearing without a puller, you will need a vice and a mandrel (you can use an old bearing race). For Almera Classic With ABS, it is important not to damage the sensor when dismantling - its cable often sticks to the hub.

Selection of spare parts: original vs analogues

On Nissan Almera Classic (2006–2012), two types of bearings were installed depending on the year of manufacture and configuration. Original articles:

• 🔧 Front hub bearing — 40520-4M000 (for models before 2010) or 40520-4M010 (after 2010).
• 🔧 Hub assembly — 40500-4M000 (if the bearing is inseparable).
• 🔧 Hub nut — 40526-4M000 (disposable, must be replaced!).

The cost of original parts is high (bearing - from 4,000 rubles, hub - from 8,000 rubles), so many choose analogues. Among the trusted brands:

• 🏆 SKF (article VKBA 3603) - the best price/quality ratio, resource 100+ thousand km.
• 🥈 NTN (article 4T-40520) is the original supplier for Nissan, but is often counterfeited.
• 🥉 FAG (article 713614050) - reliable, but expensive (from 3,500 rubles).
• ⚠️ Budget options (For example, Febi or Optimal) - risk of rapid wear, suitable only for temporary replacement.

Important nuance: On Almera Classic with engines QG15DE And QG18DE (1.5 and 1.8 l) bearings are interchangeable, but on versions with ABS (article number 40520-4M010) there is an additional groove for the sensor. Check this before purchasing!

How to distinguish a fake NTN or SKF?

Counterfeit bearings often have:

1) Uneven logo engraving (the original is clear, with uniform relief).

2) A box without a hologram or with typos in the article.

3) Weight is 10-15% less than the original (weigh before purchasing!).

4) Plastic plugs instead of metal ones (the SKF original always has metal).

Step-by-step replacement instructions

The bearing replacement process Nissan Almera Classic takes 3–5 hours depending on experience. Follow the instructions strictly in order to avoid mistakes.

1. Preparation and removal of the wheel

Place the car on a level surface, tighten the handbrake and place chocks under the rear wheels. Loosen the wheel nuts (but do not remove them completely!). Jack up the car and remove the wheel. Then:

1. Remove the hub protective cap (pry it off with a screwdriver).
2. Loosen the hub nut with a 30mm socket (you may need a wrench extension).
3. Disconnect the ABS sensor (if equipped) and the brake caliper (hang it on a wire without disconnecting the hose!).
4. Remove the brake disc by unscrewing the 2 bolts securing it to the hub.

2. Dismantling the hub and bearing

Now you need to remove the hub. To do this:

1. Unscrew the hub nut completely and remove it.
2. Unscrew the 4 bolts securing the hub to the steering knuckle (19 mm head).
3. Carefully remove the hub from the drive shaft. If it is stuck, use a puller or lightly tap it with a hammer through a wooden spacer.

To remove the bearing:

• 🔨 Remove the retaining ring from the back of the hub (use round nose pliers).
• 🔧 Clamp the hub in a vice and use a puller or mandrel to press out the bearing. If it gets stuck, pre-treat it with WD-40.
• 🧹 Clean the seat from dirt and rust (use a metal brush).

3. Installing a new bearing

The new bearing is installed in the reverse order:

1. Place the bearing in the hub mounting hole strictly exactly (misalignment will cause damage).
2. Press it in using a puller or a vice. The pressure should only be applied to outer ring!
3. Reinstall the retaining ring.
4. Apply a thin layer of grease to the inner race of the bearing.

When pressing without a puller, use the old bearing race as a mandrel. Never hit a new bearing directly with a hammer! This will damage the balls and reduce its life.

4. Assembly of the unit

Reassemble everything in reverse order:

1. Install the hub on the drive shaft and bolt it to the steering knuckle (tightening torque 80–100 Nm).
2. Install the brake disc and secure the caliper.
3. Install a new hub nut and tighten it with a torque wrench (200–220 Nm).
4. Connect the ABS sensor (if disconnected).
5. Install the wheel and lower the car.

Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing a wheel bearing with Nissan Almera Classic. Here are the most common:

• ❌ Using an old hub nut. It deforms when tightened and does not provide reliable fixation. Always install a new one!
• ❌ Distortion during pressing. If the bearing is installed crookedly, it will heat up and quickly fail. Use a puller or a straight mandrel.
• ❌ Lack of lubrication. The bearing comes with factory lubricant, but an additional thin layer Litol-24 on the clip will not hurt.
• ❌ Ignoring the retaining ring. Without it, the bearing may rotate in its seat.
• ❌ Tightening the hub bolts tightly. The torque should not exceed 100 Nm, otherwise the steering knuckle will be deformed.

One more critical error — do not check the operation of the ABS sensor after assembly. On Almera Classic it is often damaged when the hub is removed. If after replacement the ABS light is on on the dashboard, check the integrity of the sensor cable and connector.

⚠️ Attention: If, after replacing the bearing, vibration appears on the steering wheel when braking, most likely the brake disc was deformed during removal. In this case, it needs to be sharpened or replaced.

When to contact service

Despite its apparent simplicity, replacing the wheel bearing with Nissan Almera Classic may be an overwhelming task in the following cases:

• 🔧 You don't have bearing puller or a vice. Without them, it is almost impossible to press the bearing evenly.
• 🔧 Got stuck hub bolts or drive nut, and they are resistant to WD-40 and a hammer.
• 🔧 Installed on the car ESP system or reinforced brakes (for example, on versions for Europe), which complicates dismantling.
• 🔧 You discovered steering knuckle damage or drive shaft — here you will need a welding machine or turning work.

Cost of work in the service for Almera Classic varies:

• 💰 Bearing replacement (without spare parts) - RUB 3,000–5,000.
• 💰 Replacement of the hub assembly - 5,000–7,000 rubles.
• 💰 Diagnostics of the chassis (if needed) - 1,000–1,500 rubles.

If you are not confident in your abilities, it is better to entrust the work to professionals. This is especially true for owners Almera Classic with a mileage of 200 thousand km - there are often “surprises” here in the form of rusty bolts or worn out silent blocks of levers, which complicate the process.

Prevention: how to extend the life of a bearing

Wheel bearing service life Nissan Almera Classic can be increased if you follow simple recommendations:

• 🛣️ Avoid driving through deep puddles. Water enters the bearing through damaged boots, causing corrosion.
• 🚗 Check the torque of the hub nut. Tightening too loose leads to backlash, too tight leads to overheating.
• 🔧 Check wheel play regularly (once every 20 thousand km). Early diagnosis will prevent bearing failure.
• 🛠️ Lubricate the boots silicone grease - this will prevent them from cracking.
• ⚠️ Don't ignore extraneous sounds. A hum at a speed of 60–80 km/h is the first sign!

On Almera Classic with engine QG18DE (1.8 l) bearings fail more often due to the greater weight of the motor. If you operate the car in difficult conditions (taxi, cargo transportation), reduce the inspection interval to 10–15 thousand km.

FAQ: Frequently asked questions about bearing replacement

Is it possible to drive with a humming bearing?

For a short time (up to 500–1000 km) - yes, but only if there is no play or grinding noise. Driving for a long time with a worn bearing leads to:

• 🔥 Overheating of the hub and risk of jamming.
• 🚗 Accelerated wear of the CV joint.
• ⚠️ Loss of control at speed.

At the first sign of a rumble plan for replacement within 1–2 weeks.

Which bearing is better: original or SKF?

Original bearing (40520-4M000) lasts longer (120–150 thousand km), but costs 2 times more SKF. If your budget is limited, SKF VKBA 3603 — optimal choice: resource 100+ thousand km with proper installation. The main thing is to avoid fakes (check the hologram and weight!).

Does the hub assembly need to be replaced?

On Almera Classic Before 2010, the bearing was often sold separately from the hub. Replace the hub assembly (40500-4M000) is only advisable if:

• 🔧 The bearing seat is deformed or deeply corroded.
• 🔧 The bearing is “stuck” and cannot be removed without damaging the hub.
• 💰 The difference in price between the bearing and hub assembly is minimal (sometimes it is cheaper to take an assembly unit).

What should I do if there is still a hum after replacement?

The reasons may be as follows:

1. The bearing is installed crookedly — check the play and uniform rotation of the wheel.
2. The boot is damaged — the lubricant has leaked out, the bearing is running dry.
3. Worn CV joint — its crunch is similar to the hum of a bearing (checked when the steering wheel is turned completely).
4. The hub nut is loose — tighten it with a torque of 200–220 Nm.

If the problem persists, contact us for diagnostics.

Is it possible to replace a bearing without a puller?

Yes, but it's risky. Alternative ways:

• 🔨 Hammer and mandrel: carefully knock out the old bearing through the wooden spacer, press the new one in using the old race.
• 🔧 Vise: Clamp the hub and squeeze slowly, using the old bearing as a mandrel.

⚠️ Danger: Without a puller, it is easy to damage the seat or install the bearing crookedly. If you don’t have experience, it’s better to rent a puller (costs ~500 rubles per day).
