Operation Nissan Almera generation G15 in conditions of Russian roads requires close attention to the suspension. One of the critical components ensuring traffic safety is the wheel hub assembly. If this part fails, there is a risk of wheel seizure or loss of control, especially at high speed.
Many owners are faced with the problem of finding the right wheel bearing, since the design of the unit depends on the availability of the system ABS. An error in selecting the part number may result in the sensor not being able to read revolutions, which will cause an alarm message on the dashboard. In this article, we will look in detail at how to choose the right spare part, what analogues exist, and how to properly perform the replacement yourself.
Design features of the unit and the role of ABS
On Nissan Almera G15 The front hub is a complex unit consisting of two rows of ball bearings, a cage and seals. The key difference between versions with an anti-lock braking system is the presence of a magnetic ring or a built-in wheel angle sensor. Without this element, the electronics will not be able to control the moment the wheel locks during emergency braking.
When choosing a spare part, it is necessary to take into account that the bearing with ABS has a special groove or magnetic insert in the cage, which interacts with the sensor. A regular bearing designed for cars without ABS will not ensure the correct operation of the safety system. It is important to check the presence of a sensor when purchasing, since it is sometimes difficult to visually distinguish parts if you do not look at the article number.
Node design on Nissan Almera designed for high loads. The bearing must withstand both radial and axial forces encountered when turning the steering wheel and cornering. Any deviation in geometry or wear of the cage leads to the appearance of play, which over time destroys the hub and brake disc.
Original articles and cross-references
The main question that worries car owners is article number original spare parts. For Nissan Almera G15 with the system ABS There are several options for numbers depending on the manufacturer and year of manufacture of the car. The original is often marked as 40202-1HF0A or 40202-1HF0B. However, catalogs may be updated, and it is better to check the VIN code.
There are many quality alternatives that offer better prices or faster delivery. Leading manufacturers such as Koyo, NTN and Timken, are often direct suppliers to the Nissan assembly line. Their products meet all factory standards, but are cheaper than the original packaging.
Below is a table with the most popular part numbers for front wheel bearings with ABS:
| Manufacturer | Article | Note |
|---|---|---|
| Nissan (Original) | 40202-1HF0A | Standard equipment |
| Koyo | 40202-1HF0A (or equivalent) | Direct supplier |
| NTN | 40202-1HF0A (or equivalent) | High reliability |
| SNR | R153.52 | Popular European analogue |
| Febest | NASN-0124 | Budget option |
When ordering in the online store, be sure to indicate the availability of ABS. If you make a mistake and buy a version without a sensor, you will not be able to install it, since the engine management system will generate an error and block the operation of the traction control system.
⚠️ Attention! When purchasing analogues, always check for the presence of a magnetic ring on the end of the bearing. Make sure it is not damaged and securely fastened.

Symptoms of malfunction and diagnosis
Determine wear wheel bearing can be based on a number of characteristic signs that become noticeable when moving. The very first signal is a hum or howl, which intensifies with increasing speed. The sound may change when you turn the steering wheel: if the noise disappears when you turn left, it means the right wheel bearing is worn out, and vice versa.
The second important symptom is the appearance of play in the wheel. To check, you need to jack up the car, grab the wheel with both hands (top and bottom) and rock it. If you feel a noticeable gap, it means the unit requires immediate replacement. Ignoring this sign may result in the hub simply “breaking off” along the way.
An equally alarming signal is the lighting of the ABS lamp on the dashboard. This occurs because a worn bearing has runout, and the sensor cannot correctly read the signal from the magnetic ring. In this case, the system is disabled and the vehicle no longer has anti-lock braking function.
- 🔊 The appearance of a hum or howl, depending on speed.
- 🔄 Change the noise when turning the steering wheel left or right.
- 💡 The ABS or ESP indicator lights up on the instrument panel.
- 🔧 Noticeable play in the wheel when swinging with your hands.
⚠️ Attention! Don't ignore even the faintest hum. Bearing wear can lead to overheating of the hub and the wheel seizing while driving, which can lead to a serious accident.
Tools and preparation for replacement
Replacing the wheel bearing with Nissan Almera G15 - a task of medium complexity that requires a specialized tool. You will need a hydraulic press or a powerful vice, since dismantling the old bearing without them is extremely difficult. You will also need a circlip puller, a set of sockets, a wrench and a torque wrench.
Before starting work, it is necessary to prepare the workplace and ensure safety. The car must be securely supported on stands and the wheel removed. Be sure to disconnect the battery terminal to avoid short circuit when working with ABS sensors.
- 🔑 Set of sockets and ratchets (including on
17,19,21mm). - 🛠 Hydraulic press or powerful vice for pressing.
- 🔨 Hammer and punch (for carefully knocking out parts).
- 🧴 Bearing lubricant and brake cleaner.
☑️ Preparing to replace the bearing
Step-by-step replacement instructions
The replacement process begins with dismantling the wheel and unscrewing the hub nut. The nut is often tightened with a large torque, so a special wrench or the use of a lever may be required. After removing the nut, it is necessary to unscrew the bolts securing the brake caliper and hang it on a wire so as not to damage the brake hose.
Next, disconnect the ABS sensor connector, which is located next to the hub. Be extremely careful as the sensor wiring is fragile and breaks easily. After this, the bolts securing the steering knuckle to the suspension arms are unscrewed, and the hub is pulled out.
The most difficult stage is pressing the old bearing out of the steering knuckle. To do this, a press is used that presses on the inner race, pushing out the outer one. It is important not to press on the outer race as this will damage the bearing. After removing the bearing, it is necessary to thoroughly clean the seat in the fist from dirt and rust.
The new bearing is installed using a press, pressing on the outer race. This is a critical point: if you push on the inner race, you can damage the bearing before installation. The hub is pressed inside the new bearing, after which the unit is assembled in the reverse order.
Common mistakes when replacing
If you press on the inner race of the bearing during pressing, the ball bodies may be damaged, which will lead to rapid failure of the unit. It is also dangerous to overtighten the hub nut without a torque wrench - this can deform the bearing.
Critical points during assembly
When assembling the unit, pay special attention to the tightening torque of the hub nut. For Nissan Almera G15 this parameter is approximately 190-200 Nm. Failure to tighten the nut will lead to play and rapid destruction of the bearing, and overtightening can cause jamming or deformation of parts.
It is also important to connect the ABS sensor correctly. Make sure the wire is not stretched or kinked. The gap between the sensor and the magnetic ring must be within factory tolerances for the system to function correctly. After assembly, it is necessary to check the operation of the system at idle and while driving.
The final step is to check the wheel toe angle. Any interference with the suspension elements, especially when removing the arms, can disrupt the wheel alignment. Without professional tuning, the car may “steer” to the side, which is dangerous for driving.
⚠️ Attention! Do not use a hammer to drive the new bearing into the fist. This is guaranteed to damage the separator and shift the seating dimensions, making the part unusable.
Before starting work, be sure to take a photo of the location of the wires and connectors of the ABS sensor so as not to confuse their position during assembly.
Comparison of manufacturers and choice of quality
The auto parts market offers a wide selection of brands, and choosing the right manufacturer is the key to long-lasting repairs. Original parts Nissan guarantee compliance with all standards, but their prices are often inflated. However, the conveyor uses bearings from Koyo or NTN, which can be purchased separately at a better price.
Budget options from little-known brands may be suitable for temporary use, but their resource is much lower. Cheap bearings often have low-quality steel, insufficient lubrication and imprecise geometry. This leads to the fact that after 10-20 thousand kilometers the unit begins to make noise again.
It is recommended to choose proven manufacturers in the mid- and premium segments. SNR and Timken have established themselves as reliable suppliers with high resources. It is important to buy spare parts from official stores to avoid counterfeits, which are often found on sale.
- 🏆 Koyo and NTN - the best analogues, often identical to the original.
- 🛡 SNR and Timken — high reliability and long service life.
- ⚠️ Avoid nameless brands with suspiciously low prices.
Choosing a quality bearing is an investment in safety. Skimping on this part can lead to costly suspension repairs in the future.
