The stabilizer link and support bearing are suspension elements that experience enormous loads during vehicle operation. For owners Nissan Note first generation (E11 body), this problem becomes especially relevant after a mileage of 80–100 thousand kilometers. Noise when turning the steering wheel in place or knocking on bumps are the first bells indicating the need for intervention.
Many car owners ignore these signals, believing that the problem is in the shock absorber struts. However, it is support bearing is the weak link in the front suspension of this model. Without timely replacement, a damaged element can damage the body cup or deform the rack, which will lead to expensive repairs.
Design and role of the support unit in the Nissan Note E11 suspension
In the design of the front suspension Nissan Note E11 MacPherson strut is used, where the support bearing performs a dual function. On one hand, it holds the top of the shock absorber, transferring the weight of the car to the body. On the other hand, it ensures that the strut rotates when the wheels are turned. This is a complex assembly consisting of a housing, a rolling bearing and a protective cover.
The peculiarity of this unit is that it is not adjustable. When a bearing fails, the entire structure begins to work with gaps. Support bearing exposed to dirt, moisture and salts, which get inside even with intact anthers. Wear of the cage or destruction of the balls leads to jamming or backlash.
If you hear a characteristic grinding noise when the steering wheel rotates, it means that the lubricant inside the unit has dried out or leaked out. In this case Nissan Note loses controllability at low speeds, and the steering wheel becomes “wobbly” or, conversely, too tight at certain turning points. Ignoring the problem will cause the bearing axle to break the upper shock absorber cup.
Diagnosis of faults: how to understand that a bearing is dead
The malfunction can be determined both by sounds and by tactile sensations while driving. The surest sign is a dull knock or creaking sound that is heard when driving over bumps and turning the steering wheel in place. It is important to distinguish this sound from the knocking of stabilizer struts or silent blocks of levers, since diagnostic methods differ.
For an accurate check, you need to lift the front of the car or remove the wheel. Then you need to rock the shock absorber strut with your hands at the top. If you feel play or hear a crunch, it means support bearing requires immediate replacement. It is also worth checking the condition of the boot and thrust washer, which are often destroyed before the bearing itself.
A visual inspection often reveals traces of rust on the shock absorber rod or deformation of the upper mount. If traces of paint or metal appear on the body, it means that the unit is already very worn out and operates with critical clearances. Do not delay repairs as this may affect driving safety.
Choice of spare parts: original or high-quality analogue
When choosing a spare part for Nissan Note E11 Many people are faced with a dilemma: take the original or trust analogue brands. Original from Nissan guarantees a perfect fit, but it is often overpriced and its service life does not always correspond to the price. Often inside the original packaging there are products from the same factories as high-quality analogues.
There are proven manufacturers on the market who have proven themselves to be the best. Such brands include Kayaba, SNR, NTN and 555 (Sakura). These companies use higher quality alloys and improved seals, which extends the life of the assembly. However, it is important to avoid cheap fakes that may fall apart after a couple of thousand kilometers.
Be sure to pay attention to the package. A good kit should include not only the bearing itself, but also a new spring (if it has sagged), a thrust washer and a boot. Replacing only the bearing without changing the accompanying elements often does not give the desired result and requires repeated dismantling.

Preparatory stage and necessary tools
Before starting work, make sure you have all the necessary tools and lifting equipment. You will need a jack, body stands, a set of sockets and wrenches, and a spring puller. Without a special puller, compressing the spring manually is almost impossible and extremely dangerous.
Don't forget to purchase bearing grease and cleaner. It is also recommended to have a penetrating lubricant (such as WD-40) on hand to treat soured bolts securing the strut to the steering knuckle. Support bearing often sticks to the cup, and without pre-treatment it can be damaged during dismantling.
It is better to carry out work on a flat surface, preferably in a garage with a pit or on a lift. Make sure the vehicle is securely supported as the strut is under high spring pressure. Any error in spring compression can result in serious injury.
☑️ Preparation for replacement
Step-by-step instructions for replacing a support bearing
The replacement process begins with removing the wheel and disconnecting the brake caliper. It is better to hang the caliper on a wire so as not to damage the brake hose. Then the bolts securing the strut to the steering knuckle are unscrewed. After this, you can remove the strut itself, complete with the spring.
On the workbench, the stand must be secured in a vice (with caution!) and the spring compressor must be installed. Having compressed the spring until the load leaves the support, unscrew the shock absorber rod nut. Now you can remove the old upper support and support bearing. Clean the seats from dirt and rust.
Install a new bearing and support, reassemble the assembly in reverse order. Be sure to tighten the stem nut to the recommended torque. After assembly, the rack can be installed on the car. It is important to check the tightness of all mounting bolts only after the wheel is lowered to the ground and the load is placed on the suspension.
During the replacement process, pay attention to the condition of the boot and bump stop. If they are cracked or cut, they need to be replaced. Otherwise, the new bearing will quickly fail due to dirt. Replacing the support bearing without replacing the boot is a waste of time and money.
Features of tightening the rack bolts
The strut to knuckle bolts require the use of a torque wrench. The recommended tightening torque is usually 100-120 Nm, but it is better to clarify this information in the service documentation for the specific modification of the Nissan Note E11.
Before disassembling the strut, mark the position of the adjusting bolts (if any) relative to the lever in order to maintain the basic wheel alignment angles and not go for alignment immediately after replacement.

The choice of article directly affects the quality of installation. If you buy an analogue, make sure that the geometry of the seats matches the original. Differences in metal thickness or hole pattern may result in inability to install or rapid wear.
⚠️ Attention: Do not reuse the rack mounting bolts if they show signs of stretching or damage to the threads. This is critical to the safety of the vehicle.
Consequences of operating with a faulty bearing
Driving for a long time with a faulty support bearing can lead to a chain reaction of breakdowns. First of all, the upper cup of the body is destroyed, which requires expensive welding and painting. The shock absorber also suffers: due to distortions, it can begin to leak or jam.
In addition, the suspension geometry is disrupted, which leads to uneven tire wear. You may notice that the rubber wears off faster on one side, despite a fresh alignment. This happens because the stand is not vertical, but is tilted at the wrong angle.
Deterioration in handling is the most dangerous aspect. During a sharp maneuver or emergency braking, the suspension may not withstand the load and break. In such a situation, the car loses control, which can lead to an accident. Therefore, replacement should be carried out at the first sign of failure.
Timely replacement of the support bearing saves the body from corrosion and deformation, and also maintains the vehicle's directional stability at high speeds.
FAQ: Frequently asked questions
Is it possible to replace just the bearing without changing the support?
This is technically possible if the support body does not have cracks or deformations. However, in practice, old supports often wear out, and the new part will quickly fail. It is recommended to replace the assembly.
Do I need to do a wheel alignment after replacement?
Yes, definitely. When removing the strut, the wheel alignment angles are violated. Without wheel alignment adjustments, the tires will wear unevenly and the steering wheel may not be level.
How long does it take to replace a Nissan Note E11?
An experienced technician can change a pair of support bearings in 1.5–2 hours. A beginner without experience and a special puller may need 3-4 hours, since working with springs requires caution.
Is it possible to drive until it is replaced if there is a knocking noise?
You can drive, but be careful. Avoid sharp turns and large bumps. However, you should not delay repairs, since the destruction of the unit can occur suddenly.
Which brands are the most reliable for Nissan Note?
According to reviews from owners, they are considered the most reliable Kayaba and SNR. They offer the best price-quality ratio, withstanding Russian roads better than their cheap counterparts.
