Owners Nissan Almera N16 often encounter a characteristic metallic grinding sound when turning the steering wheel in place. This sound almost always indicates wear. support bearings shock absorber struts. This part is a critical element of the suspension, ensuring smooth rotation of the spring and shock absorber during steering operation.
Ignoring the symptoms leads to the destruction of the body glass and a violation of the geometry front suspension. In this article, we will look in detail at how to correctly diagnose a malfunction, choose a high-quality spare part, and perform the replacement yourself, saving on service costs.
The design and role of the support bearing in the suspension
Front suspension design Nissan Almera N16 implies the presence of a unit connecting the shock absorber strut to the car body. This is where it is located support bearing, which allows the rack to rotate with the steering wheel without creating friction against the stationary body.
If a bearing fails, play or jamming occurs. This not only causes noise, but also causes the steering wheel to stop returning to center after turning. In severe cases, the rubber insert is destroyed, and the metal cup begins to hit the metal cup of the body.
It is important to understand that Nissan Almera this part was often changed as part of warranty campaigns in the early years of production, but over time the resource is exhausted. Regular check unit condition should be part of your maintenance schedule.
Malfunction diagnosis: symptoms and testing methods
The first signal of a problem is a knocking sound when driving over uneven surfaces or a specific creaking sound when turning the steering wheel. However, sound is not always easy to localize. For accurate diagnosis, you need to know how to check the unit without disassembling.
The easiest way is to open the hood and have a helper turn the steering wheel while standing on the ground. If you hear a crunching sound or feel jerking through the shock absorber body, it means the bearing is destroyed. Also pay attention to the play at the top of the rack.
Sometimes the problem is disguised as a faulty steering rack. To rule out this option, check the condition of the boot and the bearing itself. It often happens that only the top part changes, but shock absorber and the spring remain intact.
⚠️ Attention: Do not try to ignore the knocking sound when turning the steering wheel in place. Destruction of the support bearing can lead to wheel jamming or damage to the body shell, the repair of which is much more expensive than replacing the spare part.

Selection of quality spare parts: brands and analogues
The spare parts market offers a huge selection of options, from cheap fakes to original parts. For Nissan Almera N16 It is critical to choose a product with high-quality separation and seal. Cheap analogues quickly lose lubrication and begin to make noise.
Among the trusted manufacturers are: SNR, Koyo and NTN. These brands supply components to assembly lines, so their quality is as close as possible to the original. Avoid products without packaging or with questionable labeling.
When purchasing, pay attention to the presence of anther. If it is damaged or missing, the bearing will quickly fail due to dirt and moisture. Complete solution With a new cup and nut, the price is often better.
- SNR is an excellent balance of price and quality, often included with a support.
- Koyo - Japanese quality, ideal for harsh operating conditions.
- General (Genral) is a budget option, but requires careful inspection before installation.
Tools and preparation for replacement
Before starting work, prepare the necessary set of tools. You will need a jack, safety stands, a set of sockets and wrenches, and a spring puller. No special equipment compress the spring It won't be safe.
Be sure to check the presence of penetrating lubricant (WD-40 or equivalent), as the shock absorber rod nut often sticks. Also prepare a hammer and a pry bar to remove the stand from its seat.
☑️ Preparation for replacement
Don't forget about safety. Work only on a level surface and use stands under the body. A jack is only a lifting tool and not a support for working under a vehicle.
What to do if the stem nut does not unscrew?
If the nut is stuck, use a gas torch to heat it, but be careful with the rubber parts. You can use a special key to keep the rod from turning.
Step-by-step instructions for replacing a support bearing
Remove the wheel and unscrew the caliper mounting nuts. Hang the caliper on a wire to avoid damaging the brake hose. Then unscrew the bolts securing the strut to the steering knuckle.
Remove the shock absorber completely. Place it in a vice or on a stand to compress the springs. Compress the spring evenly on both sides so as not to damage its coils and avoid injury.
Unscrew the shock absorber rod nut and remove the old support with bearing. Clean the seat from dirt and rust. Install new support bearing, making sure it is level.
Reassemble the assembly in reverse order. Do not tighten the rod nut all the way right away; do this after installing the rack on the car and lowering the car onto the wheels so that the spring takes its natural position.
- Clean the seat from corrosion before installing a new part.
- Check the condition of the shock absorber boot during disassembly.
- Use a torque wrench to final tighten the bolts.
Before compressing the spring, mark with a marker the position of the coils relative to the support. This will help to correctly install the new part and avoid misalignment during assembly.

Common replacement errors and their consequences
One of the most common mistakes is not tightening the stem nut correctly. If you tighten it too much, the bearing may seize. If it is not enough, backlash and knocking will appear.
Another mistake is ignoring the condition of the spring cup. If there is deep corrosion on the metal, the new part will quickly collapse. Stripping and priming required before installation.
⚠️ Attention: Do not use a hammer to knock out the support bearing directly into the housing. This may deform the glass and make installation impossible.
Don't forget about wheel alignment. After replacing any suspension elements, especially those that affect the geometry, it is necessary to adjust the wheel alignment angles. Otherwise, the tires will wear unevenly.
Proper tightening of the shock absorber rod nut is done only after the car is lowered on the wheels so that the spring is under load.
Maintenance and service life extension
In order for new bearings to last a long time, it is necessary to monitor the condition of the anthers. If the rubber is cracked, water and dirt get inside, which kills the bearing in a couple of seasons. Regular washing suspension in winter is also important.
Avoid sharp impacts on the suspension when driving through potholes. Driving speed on bad roads should be reduced. This will preserve not only the bearings, but also other elements of the chassis.
Make sure that water does not accumulate in the area of the support cups. Check the drainage holes in the arches. Moisture accelerates metal corrosion and destroys rubber elements.
How often do support bearings need to be replaced?
Statistics show that on the Nissan Almera N16 they last an average of 60-80 thousand kilometers, but with aggressive driving or bad roads the period is reduced to 40 thousand.
FAQ: Answers to frequently asked questions
Is it possible to replace only the bearing and not the entire support?
This is technically possible, but not recommended. The old bearing may have hidden defects, but the new part will work better with the new bearing to ensure sealing and longevity.
Is it necessary to do a wheel alignment after replacement?
Yes, definitely. Any intervention in the suspension, especially the removal of arms or struts, can disrupt the geometry of the wheels. Without alignment, tires will wear out very quickly.
Why did the knocking noise not go away after replacing the bearings?
Perhaps the problem was not only with them. Check the silent blocks of the levers, steering tips and the condition of the shock absorbers. Often, knocking masks several faulty components at the same time.
Can I use the grease included in the kit?
Yes, the grease included in the kit is usually suitable for this purpose. However, to extend service life, you can additionally use a special lithium grease for bearings.
