Operation Nissan Tiida in the conditions of domestic roads inevitably leads to wear of the chassis, and one of the most common components that require attention is the wheel bearing. Ignoring the first signs of a malfunction can lead to wheel jamming while driving, which poses a direct threat to traffic safety and costly repairs.
The replacement process requires not only the availability of specialized tools, but also an understanding of the suspension design of a particular body. Depending on the year of manufacture and modification (sedan or hatchback), the dismantling technology may differ, so it is important to strictly follow the recommendations for your car.
Symptoms of wear and diagnostics of the unit
The first signal that the wheel bearing Nissan Tiida requires replacement, a characteristic hum becomes, changing tone when turning the steering wheel. If the sound increases when turning left, then the problem is in the right wheel, and vice versa, since when turning the load shifts to the outside.
In addition to acoustic signs, it is worth paying attention to the beating of the steering wheel or the vibration transmitted to the body when driving at high speed. Sometimes wear is accompanied by wheel play, which can be detected by jacking up the car and shaking the wheel with your hands in a vertical plane.
Absolutely unacceptable continue to operate the machine with a noticeable hum, since destruction of the separator can lead to jamming of the unit at the most inopportune moment.
⚠️ Attention: If during diagnostics you find a strong play in the hub or hear a metal grinding sound, stop driving immediately. A damaged bearing can damage the steering knuckle, requiring replacement of the entire assembly rather than just a part.
- The appearance of a low-frequency hum, increasing with increasing speed.
- Changing the tone of the sound when changing lanes or turning.
- Vibration of the steering wheel, similar to unbalanced tires, but does not disappear after balancing.
- Increased hub temperature after a trip without active braking.
Selection of spare parts and necessary tools
For quality repairs, it is extremely important to choose the right set of spare parts. The market offers both original parts from Nissan, as well as high-quality analogues from trusted brands. Cheap, nameless bearings often fail after a couple of thousand kilometers.
Manufacturers are considered the best alternatives to the original Koyo, SKF, FAG or Timken. When purchasing, be sure to check the completeness: often the kit includes a new hub nut, which is disposable and must be replaced every time it is disassembled.
The necessary tool kit includes a hydraulic press or puller to press out the bearing if you are only replacing it, or a heavy-duty socket set to remove the hub assembly. For Nissan Tiida the second generation is often easier to replace the hub assembly than to press out the old unit.
The original hub nut has a special flared edge and, once tightened, cannot be reused under any circumstances.
- Set of sockets from 14 to 32 mm with extensions.
- Powerful torque wrench for tightening critical connections.
- Snap ring puller and circlip puller.
- Hammer, trowel, and penetrating lubricant (WD-40).
Removing the wheel and brake system
Start by securing the car on a level surface and placing chocks under the opposite wheels. Loosen the wheel bolts with the vehicle stationary, then raise the desired side using a lift or jack. Remove the wheel and thoroughly clean the area around the hub of dirt and road dust.
Next you need to remove the caliper. Unscrew the two caliper guide bolts and hang it on a wire to the suspension spring so as not to damage the brake hose. Remove the brake disc by first unscrewing the guide screw securing it to the hub.
If you have Nissan Tiida With rear disc brakes, the process is similar, but requires attention to the parking brake. If you have drum brakes, you will have to remove the drum, which can be more difficult due to corrosion.
Key 17 mm Typically used to remove caliper guide bolts, but always check the specific size on your vehicle.
☑️ Preparation of the workplace
Disconnecting the steering knuckle and strut
This is the most labor-intensive stage of the work, requiring significant physical effort. You will need to unscrew the nut securing the ball joint and the bolt securing the strut to the steering knuckle. These bolts often stick, so use penetrating lubricant liberally.
It is also necessary to disconnect the ABS sensor from the steering knuckle. Be extremely careful as the sensor wire is fragile and can easily break if handled roughly. Carefully unfasten the fasteners and move the tourniquet to the side.
After unscrewing all fasteners, the steering knuckle should become movable. Pull the axle shaft out of the hub using a puller. If the axle shaft is stuck, you can lightly hit it through a piece of wood to dislodge it from its seat.
Remember that when removing the strut, the shock absorber may shoot out sharply, so fix its position until complete dismantling.
- Unscrew the nut securing the ball joint to the steering knuckle.
- Remove the bolts securing the shock absorber strut to the knuckle (usually the two bottom bolts).
- Disconnect the ABS sensor wire from the bracket on the knuckle.
- Pull the splined end of the axle shaft out of the inner hub bearing.
What to do if the bolt is stuck?
If the bolt cannot be unscrewed, do not try to yank it out of place. Heat the area around the bolt with a hair dryer or torch (careful with rubber elements), pour generously with penetrating lubricant and leave for 15-20 minutes. Use an impact wrench or a long socket wrench, but be careful not to strip the threads on the post.

Bearing replacement: on a press or assembled
There are two approaches to replacement. The first is to press out the old bearing from the steering knuckle and press in a new one using a hydraulic press. This is a labor-intensive process that requires perfect cleanliness and precision.
The second, more popular option is to replace the hub and bearing assembly. For Nissan Tiida this is often the optimal solution, as it eliminates the risk of damaging the fist seats during rough press operation. The hub assembly is easier to install and quicker to replace.
If you chose the press option, carefully remove the bearing retaining ring from the knuckle. Then, using a mandrel, press out the bearing, resting on the outer ring. After this, remove the hub from the inner race of the old bearing.
The new bearing is pressed into the fist strictly along the outer ring. Do not apply force through the inner ring or rollers, otherwise you will damage the mechanism before installation.
When purchasing a hub assembly, make sure it comes with an ABS sensor and wire installed. Cheap analogues are often sold without a sensor, and it will have to be replaced from the old part, which increases the risk of breakdown.
Installing a new unit and tightening fasteners
Install the steering knuckle with a new bearing or hub in place. Insert the axle shaft into the hub until you hear a characteristic click that locks the locking ring. This is a critical point, otherwise the axle shaft may pop out while driving.
Tighten the strut-to-knuckle bolts and the ball joint nut. Use a torque wrench to maintain the required tightening torque. Typically the torque for the strut bolts is around 100 Nm, but check the manual for your year.
The most important operation is tightening the hub nut. It must be tightened with enormous force (usually more than 200 Nm) and must be jammed into the groove of the axle shaft, if this is provided for by the design. To do this, use a special wrench and an impact wrench with an adapter.
Reinstall the brake disc and caliper. Remember to connect the ABS sensor wire and make sure it does not touch any rotating parts.
Proper tightening of the hub nut is the key to a long life for the new bearing. An undertightened nut will cause play and destruction, while an overtightened nut will cause deformation of the internal elements.
Inspection and testing after repair
After assembling all the components, lower the car to the ground and remove the stops. Check the brakes: press the pedal several times to press the pads against the disc. Make sure the wheel rotates freely and is not jammed.
Take it for a short test drive at low speed. Listen to extraneous sounds. If there is no hum and the steering wheel does not vibrate, you can increase the speed and check the operation at different speeds.
Be sure to visit computer diagnostics to make sure that the ABS sensor is sending the correct signals and the brake system error does not light up on the dashboard. Sometimes when replacing it is necessary to reset the adaptations.
After 500-1000 km, it is recommended to re-check the tightness of all fastening bolts, as they may “sit” a little after the first run-in.
⚠️ Attention: Do not neglect checking the ABS sensor after installation. If the ABS light comes on after replacing the bearing, this may mean that the magnetic ring inside the new bearing has different characteristics or the sensor was damaged during installation.
How much does a replacement cost and is it possible to save money?
The cost of the service varies depending on the region and the qualifications of the technicians. On average, replacing one front bearing with Nissan Tiida costs from 3000 to 5000 rubles. The rear bearing may cost more due to the difficulty of access and removal.
Replacing it yourself allows you to save on work, but will require investment in tools. If you don't have a hydraulic press, renting equipment or purchasing a special puller may offset the benefits of doing the repair yourself.
Consider the table below as a guide to the cost of parts and labor:
| Type of work / Part | Average price (RUB) | Note |
|---|---|---|
| Hub assembly (front) | 3500 - 6000 | Depends on brand (Koyo, SKF, OEM) |
| Bearing (separately) | 1500 - 3000 | Requires special replacement tool |
| Replacement work (front) | 2500 - 4000 | Includes stand removal |
| Replacement work (rear) | 2000 - 3500 | Easier to access, but requires removal of the drum |
| Hub nut | 300 - 600 | Mandatory replacement with every repair |
Frequently asked questions from Nissan Tiida owners
Is it possible to replace just the bearing without replacing the hub?
Technically this is possible, but it is highly not recommended. Pressing and pressing requires the perfect tool. If you damage the seat in the steering knuckle, you will have to replace the entire knuckle, which is significantly more expensive.
How to understand which bearing is knocking: front or rear?
An easy way is to turn the steering wheel while turning. If the hum changes, it's from the front. If the sound is constant and does not depend on the turn, most likely it is rear. You can also shake the wheel: there is play in the place where the problem is.
Do I need to do a wheel alignment after replacement?
If you only removed the hub and did not touch the suspension arms, the wheel alignment will not be affected. However, if you unscrewed the lower arm or tie rod, then a wheel alignment is necessary.
Why did the hum appear again a month after the replacement?
This may be due to a defective spare part, incorrect installation (misalignment during pressing) or damage to the seat. It is also possible that the problem was not a bearing, but a wheel imbalance or a faulty shock absorber.
Is it possible to drive with a faulty bearing before replacing it?
Strongly not recommended. This creates the risk of the wheel seizing, losing control and causing an accident. In addition, a damaged bearing can damage other suspension components.
