Nissan Almera Classic (N16) is one of the most popular sedans on the aftermarket, but even this reliable car has weaknesses. One of them is front strut support bearing, which wears out over time and requires replacement. If you hear a knock in the suspension when driving over bumps or feel vibration in the steering wheel, the problem may lie there.
In this article we will look at how diagnose the problem yourself, what original and similar spare parts are suitable for Almera Classic 2006–2012, and we will also give step-by-step instructions for replacement, taking into account the nuances of the design. We will pay special attention to typical mistakes that car owners make during repairs and ways to extend the service life of a new bearing.
What is a support bearing and why is it needed?
Support bearing (or strut upper bearing) is a key element of the front suspension, which provides:
- 🔄 Rotate the stand when turning the steering wheel without transmitting vibrations to the body.
- 🛡️ Shock absorption from road unevenness, dampening spring vibrations.
- 🔧 Fixing the stand at the top point, preventing its displacement.
On Nissan Almera Classic are installed angular contact ball bearings closed type, which do not require maintenance, but have a limited resource - usually 80–120 thousand km. However, when driving on bad roads or after an accident, wear may occur much earlier.
Structurally, the bearing is integrated into shock absorber support (often called a “cup”) and is attached to the body through a rubber damper. When it is destroyed, not only comfort suffers, but also safety: controllability deteriorates, braking distance increases, and in critical cases the strut can even break through the hood!
- Once every 10 thousand km
- Only when knocking occurs
- Before seasonal tire replacement
- Never
Signs of a faulty support bearing on Almera Classic
Symptoms of support bearing wear are often confused with faulty struts, ball joints or silent blocks. However there is characteristic featuresthat will help you accurately identify the problem:
⚠️ Attention! If when you turn the steering wheel you can hear crunching or grinding in the area of the front pillars - this is a 100% sign of destruction of the support bearing. It is dangerous to operate the machine in this condition!
- 🔊 Knocking or clicking noises when driving over speed bumps or potholes (especially noticeable at low speeds).
- 🌀 Steering wheel vibration at speed
60–90 km/h, which disappears when braking. - 🚗 Car withdrawal to the side when driving in a straight line (the symptom may also indicate wheel alignment).
- 🔧 Steering play in the central position (checked by rocking the steering wheel left and right while the car is stationary).
For an accurate diagnosis, perform a simple test:
- Open the hood and have a helper slowly turn the steering wheel.
- Place your hand on the top of the post (next to the support).
- If you feel vibration or clicking - the bearing is worn out.
What happens if you don't change the support bearing?
If the bearing is completely destroyed, the strut loses its fixation, which leads to:
- loss of control at speed;
- damage to shock absorber rods;
- deformation of the body at the place where the support is attached.
In critical cases, the strut may break through the hood if there is a strong impact!
Which journal bearings are suitable for Nissan Almera Classic?
On Almera Classic (N16) from 2006 to 2012 bearings with catalog number were installed original — 54303-4M000 (for the left and right sides are the same). However, original spare parts Nissan are often counterfeited, so experts recommend paying attention to proven analogues:
| Brand | Article | Average price (per 1 piece) | Features |
|---|---|---|---|
| Nissan (original) | 54303-4M000 |
2 800–3 500 ₽ | High quality, but there is a risk of running into a fake |
| KYB | SM5106 |
1 800–2 200 ₽ | Optimal price/quality ratio, often comes complete with a support |
| SACHS | 804 146 |
2 100–2 500 ₽ | Reinforced design, suitable for aggressive riding |
| Febi | 22610 |
1 500–1 900 ₽ | Budget option, but the resource is lower than the original |
| SNR | R155.62 |
1 700–2 000 ₽ | A good alternative to the original, often found in stores |
When choosing, pay attention to:
- 🔍 Availability of certificate (the original must have a hologram Nissan).
- 📦 Completeness - some brands sell the bearing together with a support and a rubber damper (for example, KYB).
- 🛠️ Country of manufacture - the best analogues are made in Germany (SACHS) or France (SNR).
Before purchasing, check whether the bearing comes complete with the support or separately. On Almera Classic Most often, the entire assembly is replaced, since the rubber damper becomes tanned and loses its elasticity over time.
Tools and preparation for replacement
Replacing the support bearing with Nissan Almera Classic requires removing the shock absorber, so you can’t do without a special tool. Here's what you'll need:
☑️ Necessary tool
Also prepare:
- 🔧 New retaining rings (if the bearing is separate from the support).
- 🧴 Bearing grease (For example, Litol-24).
- 📸 Camera — take a photo of the location of the wires and hoses before disassembling.
Important points before starting work:
⚠️ Attention! Never attempt to disassemble the stand without spring puller — a compressed spring can shoot out and cause serious injury! If there is no puller, contact service.
- 🅿️ Replace with flat ground with reliable wheel supports.
- 🔋 Disable battery, since you will have to disconnect the ABS sensor (on some versions).
- 🌡️ Work in a warm box - rubber support elements become fragile in the cold.
Step-by-step instructions for replacing a support bearing
The replacement process takes 2–3 hours on one side (depending on experience). Follow the algorithm:
- Removing the stand:
- Jack up the car and remove the wheel.
- Unscrew the fastening nut
anti-roll bar(key 17). - Disconnect the brake hose from the rack (pre-secure it with wire to avoid damage).
- Unscrew the two bolts securing the rack to
steering knuckle(key 19). - In the engine compartment, unscrew the three nuts securing the support to the body (head 12).
- Disassembling the rack:
- Place the stand in a vice and compress the spring with a puller until a gap appears.
- Unscrew the shock absorber rod nut (21 wrench, hold the rod with a hexagon).
- Remove the support, rubber damper and old bearing.
- Installing a new bearing:
- Clean the seat from dirt and rust.
- Apply a thin layer of grease to the outer race of the bearing.
- Install the new bearing into the support (if it comes separately) and secure with a retaining ring.
- Reassemble the stand in reverse order, making sure spring position (the ends of the turns must fit into the grooves of the cups).
- Installing the rack on the car:
- Secure the support to the body (tighten the nuts with a torque wrench to
20–25 Nm). - Connect the strut to the steering knuckle and stabilizer.
- Install the wheel and lower the car.
- Secure the support to the body (tighten the nuts with a torque wrench to
After replacement, be sure to check and adjust wheel alignment! Even if you haven't touched the tie rods, removing the strut may disrupt the wheel alignment.

Typical replacement mistakes and how to avoid them
Even experienced car owners make mistakes that lead to knock again or rapid wear new bearing. Here are the most common:
- 🔧 Retightening the nuts — leads to deformation of the rubber damper and vibrations. Use a torque wrench!
- 🌀 Incorrect spring installation - if the coils do not coincide with the grooves of the cups, the spring may jump off.
- 🧴 Lack of lubrication — a bearing without lubrication will last 2–3 times less.
- 🔄 Using old nuts/bolts - they become deformed when tightened, so always take new ones.
- 🚗 Ignoring wheel alignment - after replacement, the angles are necessarily broken.
⚠️ Attention! If the knocking noise remains after replacement, check:- the rack is assembled correctly (perhaps you forgot to install the rubber gasket);
- condition silent blocks of levers — their wear also gives similar symptoms;
- tighten all fasteners (especially the shock absorber rod nuts).
How to extend the service life of a thrust bearing?
The bearing life depends not only on the quality of the part, but also on riding style and care. Follow these tips:
- 🛣️ Avoid sharp impacts — drive around potholes and speed bumps at low speed.
- 🌀 Monitor your tire pressure — overinflated or flat tires increase the load on the suspension.
- 🔧 Check the racks every
20 thousand km— at the slightest sign of shock absorber leakage, change it together with the support. - 🧴 Lubricate the bearing at each maintenance (if the structure is collapsible).
- 🚿 Wash your pendant in winter — salt and reagents destroy rubber support elements.
If you frequently drive on dirt roads or carry heavy loads, consider installing reinforced supports from KYB or SACHS. They are more expensive, but will last 1.5–2 times longer than standard ones.
After replacing the bearing, the first 500 km Avoid sharp maneuvers and high speeds - this will help the new parts get used to it.
FAQ: Frequently asked questions about journal bearings Nissan Almera Classic
Is it possible to drive with a knocking support bearing?
Short-term (up to 1-2 weeks) is possible, but risky. If the bearing is completely destroyed, the strut loses its fixation, which can lead to loss of control at speed. In addition, vibrations accelerate wear on the steering rack and ball joints.
How much does it cost to replace a support bearing at a service center?
Cost of work in 2026:
- Replacing one bearing -
1 500–2 500 ₽. - Replacement assembly with stand -
3 000–5 000 ₽(for one side). - Additional charge wheel alignment —
1 000–1 500 ₽.
Total you will pay for a complete replacement on both sides 8 000–12 000 ₽ (with spare parts).
Which brand of bearings is better to choose for Almera Classic?
Optimal options in terms of price/quality ratio:
- Budget — Febi or SNR (resource
50–70 thousand km). - Middle segment — KYB or Monroe (
80–100 thousand km). - Premium - original Nissan or SACHS (
120+ thousand km).
If you drive carefully, that's enough. Febi. For aggressive use, take KYB complete with support.
Do I need to change the support bearing when replacing the shock absorber?
Yes, necessarily! Even if the bearing does not knock, its life comes to an end at the same time as the shock absorber. Bearing cost (1 500–2 500 ₽) is not comparable to the complexity of removing the rack again. An exception is if the shock absorber has been changed less 30 thousand km back.
Can the support bearing be repaired?
No. The bearing is non-separable, and when it wears out just replace. Some "masters" suggest washing and lubricating the old bearing, but this is a temporary measure - after 5–10 thousand km the knock will return. The only repairable element in the support is rubber damper, but it is changed extremely rarely.
