The rear wheels of the first generation Nissan Qashqai (J10) often become a source of noise, which is mistaken for problems with the engine or exhaust system. In fact, a humming noise that changes with engine speed is a classic sign of wear and tear. wheel bearing. Owners of crossovers encounter this problem quite often, especially with a mileage of over 100 thousand kilometers, when the service life of the part comes to an end.
Ignoring this malfunction may result in the wheel seizing while driving, which can result in serious accident and damage. steering knuckle or hubs. The replacement process is not very complicated, but requires special tools and strict adherence to dismantling and installation technology. Errors at the pressing stage can reduce the service life of a new part to several thousand kilometers.
Diagnosis of faults and selection of spare parts
Before you go to the store for spare parts, you need to make sure that the problem is in the bearing. The easiest way to check is to rock the wheel. Raise the car on a lift or jack, swing the wheel with your hands in a vertical plane. Play accompanied by knocking often indicates problems with bearing or a ball joint.
The sound of a worn part usually resembles a hum or howl, which intensifies when the steering wheel is turned in the opposite direction from the damaged wheel. If the hum disappears when turning left, the problem is in the right bearing, and vice versa. On Nissan Qashqai J10 this occurs due to the redistribution of the load on the wheel when entering a turn.
When choosing a new part, it is important to understand that there are different design solutions. You need not just a bearing, but a ready-made one hub assembly with flange and ABS sensor. Trying to replace only the inner bearing race on this model is a thankless task and often impossible without a special press.
- 🔧 Original (Nissan) - high price, but guaranteed quality and accuracy of fit.
- 🔧 Premium brands (SKF, FAG, SNR) are an excellent analogue, often supplied to the assembly line.
- 🔧 Budget options (Korea, China) - risk of rapid failure, install only if there is an acute shortage of funds.
Necessary tools and preparation
To carry out the work, you will need a standard set of automotive tools, but there are critical items without which replacement will be torture. Availability required 30 mm heads (or 32 mm depending on the year of manufacture) for unscrewing the hub nut, as well as a powerful wrench or ratchet with an extension.
Pay special attention to the retaining ring remover. On Qashqai J10 it often sticks to the steering knuckle body. If you don't have a professional puller, have some heavy-duty pliers and a hammer, but be careful not to damage the threads.
Don't forget about torque wrench. The hub nut is tightened with enormous force (about 200-230 Nm), and you can’t do it by eye. An under-tightened nut will lead to play and destruction of the unit, and a twisted nut will lead to thread breakage.
⚠️ Warning: Never try to remove the hub nut without locking the wheels. On Nissan Qashqai This nut is extremely torqued and if the hub rotates you could seriously injure yourself or damage your suspension components.

The process of dismantling the old unit
Start by removing the wheel bolts and lifting the car. Remove the wheel and remove the brake caliper. Do not let the caliper hang from the brake hose - hang it on a wire or hook. After this, unscrew the caliper guides and remove the brake disc.
The next step is to disconnect the ABS sensor. On Nissan Qashqai The sensor wire is often glued to the fist or runs in hard-to-reach places. Carefully disconnect the chip and remove the wire from the fastenings. If the sensor is stuck, do not pull it with force, otherwise you will break off the sensitive element.
Now you need to unscrew the lower arm and steering tip to free the steering knuckle. Be careful: the bolts may be soured. Use penetrating lubricant beforehand. Once the knuckle is freed, you can remove the CV splined shaft from the hub. Hub with the bearing will remain in the steering knuckle.
☑️ Removing the suspension
If you plan to use a press, then the hub must be pressed out of the fist, and then the bearing itself must be pressed out. However, it is easiest for the home DIYer to use special pullers for knocking out the bearing through a mandrel suitable for the size of the inner race.
- 🔧 Use a mandrel that rests only on the outer race of the bearing.
- 🔧 Never put pressure on the inner race or separator when pressing out.
- 🔧 Lubricate the bolt threads with copper grease before assembly.
Installing a new bearing and pressing nuances
This is the most critical stage. The new part must be pressed strictly along the axes. If the bearing is misaligned during installation, it will fail within a couple of days. Use a mandrel that rests on outer ring bearing, since it is precisely this that must fit tightly to the steering knuckle housing.
Pressing should be smooth. If the part is tight, check the alignment. Do not use a hammer for direct driving as impacts may damage the cage and the balls inside. It is best to use a hydraulic press or special screw pullers.
After installing the bearing into the knuckle, push the hub inside. Here you will also need a press or a powerful vice. Critical: Never drive the hub through the bearing inner race as this will instantly destroy the rollers. Impacts should be transmitted only through the inner race of the hub, and not through the bearing itself.
Why can't you hit the inner ring?
The inner race of the bearing is rigidly connected to the cage and rollers. A blow to it transfers energy to fragile elements, causing cracks and chips that will appear in a short time.
Reassemble the assembly in the reverse order: install the steering knuckle with a new bearing on the car, connect the ABS sensor, tighten the arms and CV joint. Don't forget about the retaining ring that secures the bearing in the knuckle.
⚠️ Attention: Check the condition of the ABS sensor before installation. If there is rust or mechanical damage on its tip, it is better to replace it immediately to avoid errors on the dashboard.
Correct pressing is the key to long service life. Always press on the part of the part that will fit into the seat without play.
Comparison of manufacturers and prices
The spare parts market offers a huge selection of solutions for Nissan Qashqai J10. The original is expensive, but is often sold in beautiful packaging with low margins, as it is produced in the same factories as the branded counterparts. Therefore, buying a high-quality analogue is a reasonable saving.
The table below shows the average prices and features of popular brands for comparison. Please note that prices may vary depending on region and exchange rates.
| Manufacturer | Country | Average price (RUB) | Features |
|---|---|---|---|
| Nissan (Original) | Japan/UK | 15000 - 20000 | High quality, original packaging |
| SNR | France | 8000 - 11000 | One of the market leaders, reliable units |
| FAG | Germany | 7500 - 10000 | Excellent durability |
| SKF | Sweden | 8500 - 12000 | High production standards |
| Asva | Russia/China | 3500 - 5000 | Budget option, average quality |
When choosing, do not chase the lowest price. A bearing is a part on which safety depends. Cheap Chinese fakes often have play after 5,000 km. It is better to overpay for a proven brand than to change the unit twice a year.
When purchasing, check the integrity of the packaging and the presence of protective holograms. On genuine Nissan parts, the hologram should change color when tilted.
Check after repair
After completion of all work and tightening of all bolts, a control check must be carried out. Spin the wheel by hand - it should rotate freely, without jamming or extraneous sounds. Make sure there is no play in the suspension.
Take it for a test drive. For the first 100-200 kilometers, monitor the hub temperature. If after a ride you feel a lot of heat (not scalding, but hot), this may indicate that the bearing is overtightened or improperly installed. Normally, the hub should be warm.
Pay attention to the dashboard readings. The ABS light should go out after the engine starts. If it lights up, you may have connected the sensor poorly or damaged the wiring during dismantling. In this case, diagnostics with a scanner will be required.
- 🔧 Check the tightening of the bolts after 500 km.
- 🔧 Monitor the condition of the CV joint boots, as they could be damaged during dismantling.
- 🔧 Do a wheel alignment if you have unscrewed the levers or changed the suspension geometry.
⚠️ Attention: If squeaking or grinding noise occurs after replacing the bearing, stop immediately. This may indicate that dirt or grease has entered the assembly, requiring further disassembly.
Common mistakes when replacing
Many beginners make the mistake of trying to knock out an old bearing with a hammer. This is only acceptable if you are using the correct mandrel, but even then the risk of damaging the knuckle body is very high. A damaged housing will not provide the proper fit for a new bearing, and it will quickly fly out.
Another common mistake is ignoring the ABS sensor. On Qashqai J10 The sensor often sticks to the hub or knuckle. If you try to pull it out, it will break. Gently heat the mounting area with a hairdryer or use WD-40 to soak.
Don't forget the hub nut. It has a thread lock and must be replaced with a new one each time it is reassembled. An old nut may not be able to withstand the required tightening torque and become loose, causing the wheel to fly out. Use only new nuts with a high strength class.
What to do if the hub nut does not unscrew?
Try heating the nut with a blowtorch or a powerful hair dryer, but do not overheat the bearing. Use a long wrench and make sure the vehicle is securely secured.
FAQ: Frequently asked questions
Is it possible to replace only one bearing?
Technically it is possible, but experts recommend replacing bearings on one axle in pairs. If one is worn out, it means that the second is in similar operating conditions and will soon require replacement. Additionally, differences in wear can result in uneven braking.
Is a wheel alignment necessary after replacement?
If you have not unscrewed the lower control arm adjusting bolts or changed the tie rods, a wheel alignment is not necessary. However, if you unscrewed the bolts securing the lever to the knuckle or changed the ball joint, the procedure for adjusting the wheel alignment angles is necessary.
How long does it take to replace?
An experienced master will spend about 1-1.5 hours on one side. A beginner, without experience working with suspension and lacking special tools, may need 3-4 hours, especially if the bolts are stuck.
Why is the new bearing humming?
There may be several reasons: a defective part, incorrect pressing (misalignment), overtightening of the hub nut, or dirt getting inside the unit. In some cases, the hum goes away after 100-200 km of running.
Is it possible to drive with a faulty bearing?
Strongly not recommended. Bearing failure can result in wheel seizure, wheel separation from the hub, or damage to the brake system. This is a direct threat to life and safety on the road.
