Noise when driving a Nissan Note, are often confused with faulty shock absorbers or brake pads, but the real cause in most cases is wear front wheel bearing. This part is responsible for the smooth rotation of the wheel and absorbs enormous loads from the weight of the car and dynamic influences on the road. Ignoring the first signs of malfunction can lead to wheel jamming or hub destruction, which will create a direct safety hazard during operation.
Replacement process on popular Nissan Note the first and second generations (E11, E12) have their own design features that distinguish them from other models of the concern. It is important to understand that, depending on the year of manufacture and type of drive, the unit may be assembled in a single block with the brake disc or require separate replacement of the bearing itself. Correct diagnostics and the use of specialized tools are the key to successful repairs, allowing you to avoid repeated calls for service in the near future.
Diagnosis of faults and selection of spare parts
The first stage of work is to accurately identify the problem, since the symptoms may be similar to malfunctions of ball joints or steering joints. A characteristic sign of wear is a hum, which increases in proportion to the speed of the vehicle and can change when the steering wheel is turned. If the noise increases when turning right, the problem is most likely in the left bearing, and vice versa, since the load is redistributed to the outside of the turn.
To confirm the diagnosis, you need to lift the car on a lift and check the wheel play by grasping it at the top and bottom points. Rotating the hub by ear will also help determine the condition: even with the wheel removed, you can hear a characteristic crunching or buzzing sound. Inspection brake disc and hubs checking for rust or signs of overheating is also mandatory before disassembling the unit.
- 🔍 Listen to the sound when accelerating and braking - this will help localize the source of the noise.
- 🛠️ Use a mechanic's stethoscope to accurately identify the humming unit among other suspension components.
- 📏 Check the play with your hands to prevent wear of other steering elements.
When choosing a new spare part for Nissan Note It is critical to consider the type of attachment and assembly design. The original bearing from Nissan has a high service life, but high-quality analogues from the SKF, FAG or NSK brands often offer similar characteristics at a more affordable price. The main thing is to avoid cheap nameless products that may not withstand even the minimum loads of urban use.
Please note that for some versions Nissan Note ABS requires a bearing with a built-in magnetic speed sensor ring. Selecting the wrong part will cause the ABS fault light on the dashboard to come on. Please ensure that the packaging or catalog matches your vehicle's VIN to avoid installation errors.
Necessary tools and preparatory work
Before proceeding with dismantling, it is necessary to prepare a workplace and a complete set of tools, since the hub assembly on a Nissan Note often sticks and requires considerable effort to disassemble. You will need a set of sockets, including extensions, a torque wrench to accurately tighten the threaded connections, and a puller to press out the old bearing. Without the right tools, the risk of damaging parts or injuring yourself increases significantly.
- 🔧 Socket wrenches for 12, 17, 19, 21 and 24 mm, as well as hexagons.
- 💨 Pneumatic or electric wrench for quickly unscrewing the hub nut.
- 🔨 Hammer, pry bar and special puller for wheel bearings.
Raise the car on a lift or place it on secure stands, making sure it is stable. Remove the wheel and clean the hub area of dirt and rust using a wire brush and a penetrating lubricant like WD-40. This will make it easier to unscrew the soured caliper and steering knuckle bolts. Be sure to disconnect the battery terminal if you plan to disconnect the ABS sensor to avoid a short circuit.
Step-by-step instructions for replacing the unit
Start by removing the brake caliper by unscrewing the two guide bolts. Carefully hang the caliper on a wire or hook to avoid damaging the brake hose. Then remove the brake disc, which may be stuck to the hub - it can be easily knocked out with light blows of a hammer through a wooden spacer. After this, you need to unscrew the hub nut, which is tightened with a huge torque, so use extensions and an open-end wrench or a powerful torque tool.
The next step is to disconnect the ABS speed sensor by carefully removing it from its seat in the steering knuckle. Unscrew the bolts securing the shock absorber strut to the steering knuckle and the bolts of the lower ball joint. Once all the fasteners are loosened, you can remove the steering knuckle from the assembly. If the bearing is changed together with the hub, the process is simplified: just press out the old unit and press in the new one.
☑️ Tools for work
If you use a puller to press the bearing out of the knuckle, rest on the outer race or the inner mechanism will collapse. To press in a new bearing, use a mandrel resting on the outer ring to avoid misalignment and damage to the balls inside.
⚠️ Caution: Never use a hammer to directly drive a bearing into place - this is guaranteed to destroy its internal structure and lead to premature failure. Use only a hydraulic press or a specialized puller.
- Once a year
- Only in case of breakdown
- Once every 50,000 km
- Regularly according to regulations
New bearing installation and assembly
Before installing a new bearing, thoroughly clean the seat in the steering knuckle of rust and old grease. Make sure the surface is smooth and free of burrs that could affect the fit of the part. Press the bearing strictly perpendicularly, controlling the position to avoid distortion. After installation, make sure that the bearing is seated all the way and has no play relative to the knuckle body.
If you replaced the bearing together with the hub, install the new unit in the fist and secure it with bolts with the required tightening torque. Insert the drive shaft into the hub and install the new hub nut. Tighten the nut with a torque wrench to the torque specified by the manufacturer, usually around 180-200 Nm. After this, be sure to install a new locking pin or caulk the nut, if the design provides for this.
Return the steering knuckle to its place, connecting it to the shock absorber strut and lower ball joint. Tighten the mounting bolts to the required torque. Install the brake disc and caliper, connect the ABS sensor. Check that all elements are securely fastened and there are no unnecessary gaps. Clean all surfaces from traces of oil and grease.
- ✅ Use new bolts and nuts, as old ones may have stretched threads.
- 📐 Check the wheel alignment after replacing to avoid uneven tire wear.
- 🧼 Clean the work area of metal shavings and dirt before assembly.
Common mistakes when replacing
The mistake is often the incorrect tightening of the hub nut - too weak will lead to play, too strong - to destruction of the bearing. It is also important not to damage the ABS sensor when removing it.
Tightening torques and specifications
Precise adherence to tightening torques is a critical factor in the longevity of the repair. For model Nissan Note There are strict regulations, violation of which can lead to the destruction of threaded connections or deformation of parts. Below is a table with the main values that must be used when assembling the unit.
| Fastening element | Thread type | Tightening torque (Nm) | Special requirements |
|---|---|---|---|
| Hub nut | M24 | 180 - 200 | Mandatory replacement, caulking |
| Strut mounting bolts | M14 | 105 - 120 | Use new fastener |
| Ball joint bolts | M12 | 85 - 100 | Install the lock washer |
| Brake Caliper Bolts | M12 | 35 - 45 | Check the condition of the guides |
| ABS sensor mount | M6 | 8 - 10 | Careful tightening, fragile threads |
The use of a torque wrench is mandatory for all critical connections. If you do not have such a tool, it is strongly recommended not to do the work yourself, since an error of 20-30 Nm can be fatal to the unit. Pay special attention to tightening the hub nut - it must be secured against unscrewing, since vibrations during movement will quickly weaken the thread.
Precise torque of the hub nut and knuckle bolts is the key to the safety and longevity of your new bearing.
Checking the work and final recommendations
After assembly, it is necessary to carry out a control check of all connections. Raise the car and check whether the wheel rotates freely without any extraneous sounds. Rock the wheel in the vertical and horizontal planes to make sure there is no play. Start the engine and drive at low speed, checking that the brakes work and that there is no noise from the hub.
The first few days of operation, pay special attention to the behavior of the car. If you feel vibration in your steering wheel or hear a new noise, return to the inspection immediately. The bearing may have been installed misaligned or not fully pressed. Regularly checking the brake fluid level and the condition of the boots will also help extend the life of the unit.
- 🚗 Take a test drive at different speeds to check for the absence of hum.
- 🛑 Check the brake operation to ensure that the caliper is installed correctly.
- 🔍 Visually inspect the unit after a week for leaks or signs of overheating.
⚠️ Attention: If after replacement you hear clicks or grinding noises when turning the steering wheel in place, check that the drive shaft is installed correctly and the condition of its boot.
Before going for a technical inspection, be sure to check the wheel alignment angles, since replacing the wheel bearing could shift the wheel alignment.
