Nissan Almera Classic B10 is one of the most popular sedans on the secondary market, but with a mileage of over 150,000 km, owners often encounter wear on rubber-to-metal joints. The silent blocks of the front control arms on this model are a weak point, especially if the car was operated on rough roads or with an overloaded suspension. Their failure is manifested by knocking, the car pulling to the side and uneven tire wear.
In this article we will look at how diagnose the problem yourself, what original and similar spare parts suitable for replacement, and will also give step by step instructions with nuances for Almera Classic B10 (including restyled versions 2008–2012). We will pay special attention to typical replacement errors that lead to premature wear of new parts.
Signs of wear on silent blocks Nissan Almera Classic B10
Rubber-metal hinges of the front arms on Almera B10 rarely “die” suddenly - usually the problem accumulates gradually. The first symptoms are often attributed to wheel alignment or shock absorber malfunctions, but there are characteristic features, which directly point to silent blocks:
- 🔊 Knocking or squeaking in the front suspension when driving over uneven surfaces (especially at low speeds). The sound is often confused with worn ball joints, but it is more “dull” and radiates into the lever.
- 🚗 Pulling the car to the side when braking or accelerating, even if the wheel alignment is adjusted. This occurs due to play in the hinges, which changes the angles of the wheels.
- 🔄 Uneven tire wear (especially the inner or outer edge). If “bald patches” appear on the tire despite regular balancing, the silent blocks are to blame.
- 🛑 Vibration on the steering wheel when driving on a flat road at a speed of 60–80 km/h. This is a consequence of an imbalance caused by the displacement of the lever due to play in the hinges.
On Almera Classic B10 The silent blocks of the front levers most often fail during the mileage 120–180 thousand km, but with aggressive driving or constant loads (for example, transporting goods), the resource is reduced to 80–100 thousand km. The rear silent blocks of the levers are especially vulnerable - they are loaded more heavily than the front ones due to the MacPherson suspension design.
⚠️ Attention: If you ignore the wear of silent blocks, this will lead to deformation of the lever lugs (they “break” from the inside). In this case, you will need to replace the entire lever, which is 3-4 times more expensive.
- Once every 10,000 km
- Only when knocking occurs
- Before seasonal tire replacement
- Never checked
What silent blocks are on Nissan Almera Classic B10 from the factory
On Almera Classic B10 (including restyled versions 2008–2012) silent blocks from Nissan with catalog numbers depending on the side and position:

Febi 22639, Sidem 505456, Moog K-80055 | 2 pcs. |
Original silent blocks from Nissan They are expensive (from 1,500 to 2,500 rubles per piece), but their service life is 20–30% higher than that of analogues. However, many owners choose alternative brands:
- 🔧 Febi (Germany) - optimal price/quality ratio, soft tires, but sensitive to aggressive driving.
- 🛡️ Sidem (Belgium) - more rigid, suitable for severe operating conditions.
- 🚀 TRW or Moog - premium analogues, often superior to the original in durability.
⚠️ Attention: On Almera Classic B10 after 2010, silent blocks with reinforced metal bushings (numbers54503-4M025AAnd54503-4M030A). They cannot be replaced with standard ones - only with analogues marked “Reinforced”.
Before purchasing silent blocks, check them using the car's VIN code on the website Partsouq or Nissan TechInfo. This will help avoid compatibility errors, especially if the car was assembled for different markets (Europe/Asia).
Step-by-step instructions for replacing front control arm silent blocks
Replacing silent blocks with Almera Classic B10 requires removing the levers, so you can’t do without a pit or a lift. If you have little experience, it is better to entrust the work to professionals - mistakes when pressing new parts will lead to their rapid wear. Below are instructions for upper arm (the algorithm with the bottom one is similar, but more complicated due to the spring).
Secure the car on a lift or reliable supports|Remove the wheel and disconnect the brake caliper (hang it on a wire)|Clean the threaded connections of the lever from dirt and rust|Prepare a puller for silent blocks and a press (or a vice with mandrels)|Check the purchased silent blocks for rubber defects-->
Removing the lever and dismantling old silent blocks
1. Unscrew bolt securing the arm to the subframe (key 19). If it sticks, use a penetrating lubricant (such as WD-40 Specialist) and an impact wrench.
2. Disconnect ball joint from the steering knuckle (unscrew the nut 17 and press out the pin with a puller).
3. Remove the lever and clamp it in a vice. To dismantle the silent block, use puller or mandrel. If it is not there, you can carefully knock the part out with a hammer through a wooden spacer, but the risk of damaging the lever eye is high.
⚠️ Critical moment: Under no circumstances burn out the silent block with a gas torch! High temperature destroys the metal structure of the lever, and it becomes brittle.
Installation of new silent blocks
1. Clean the lever eye from rust and dirt. Treat it if necessary anticorrosive (For example, Dinitrol ML).
2. Check seat for the presence of burrs - they can cut through the rubber of the new silent block. Remove them with a file.
3. Install a new silent block using mandrel and press. The pressing must be smooth, without distortions. If you use a vice, control the force - excessive pressure will deform the rubber bushing.
4. After installation, check that the silent block didn't rotate in the eye by hand. Only minimal play is allowed (0.5–1 mm).
⚠️ Attention: On Almera Classic B10 The rear silent block of the upper arm has asymmetrical shape — it cannot be confused with the front one! If installed incorrectly, the rubber will quickly crack.
What to do if the silent block does not press in?
If the new silent block does not fit into the eye, check:
1. Diameter of the seat (should be 40.0 ± 0.1 mm for the front and 42.0 ± 0.1 mm for the rear).
2. Presence of factory lubricant on the rubber (if it is not there, apply Litol-24 or Molykote G-Rapid Plus).
3. Correct orientation - some silent blocks have “FRONT” or “REAR” marks.
If the problem persists, you may not have been sold a part from Almera B10, and from another model (for example, Nissan Sunny).
Typical replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that shorten the service life of new silent blocks. Here are the most common:
- 🔧 Incorrect pressing — if the silent block is installed crookedly, the rubber will crack within 10–20 thousand km. Always use a mandrel that matches the diameter.
- 🛠️ Ignoring play in the lever eye - if the metal is “broken”, the new silent block will dangle. In this case, the lever must be replaced.
- 🚫 Lack of lubrication - rubber bushings must be coated with a special lubricant (for example, Silicon-Fett), otherwise they “creak” and wear out faster.
- 🔄 Incorrect tightening torque - the bolts securing the lever to the subframe must be tightened only under load (when the car is on wheels). moment for Almera B10: 80–100 Nm.
Another common problem is buying cheap analogues without brand verification. For example, silent blocks no-name from China can last only 20-30 thousand km, after which the rubber crumbles. It's better to overpay for a proven brand (Febi, TRW, Sidem) rather than changing parts every six months.
After replacing the silent blocks, BE SURE to do a wheel alignment! Even if the angles were normal before the repair, new parts will change the suspension geometry.
Cost of work and spare parts: where is it cheaper?
The price of replacing silent blocks with Nissan Almera Classic B10 depends on the region and type of service station. On average, expenses add up like this:
| Service/Spare part | Cost (RUB) | Notes |
|---|---|---|
| Original silent block (1 pc.) | 1 500–2 500 | Price depends on position (front/rear, top/bottom) |
| Analogue (Febi, TRW) | 800–1 500 | The best option in terms of price/quality ratio |
| Replacing silent blocks (work, 1 side) | 2 000–4 000 | Includes lever removal/installation and press fitting |
| Replacing the lever assembly (if the eye is broken) | 5 000–8 000 | Price for the original, analogues are 30–50% cheaper |
Replacing it yourself will cost less, but will require tools:
- 🔧 Silent block remover - from RUB 1,500. (can be rented).
- 🛠️ Vise or press - from RUB 3,000. (if not, use a heavy hammer and mandrels).
- 🔨 A set of sockets and keys - a head for 19 and 17 is required.
⚠️ Attention: Some service stations offer a “universal” replacement of silent blocks without removing the lever (they burn out the old rubber and press in the new one). This method unacceptable for Almera B10, as it disrupts the geometry of the lever and leads to rapid wear of new parts.
How to extend the service life of silent blocks
Resource of silent blocks for Nissan Almera Classic B10 depends not only on the quality of the parts, but also on the driving style. Here are some tips to help delay replacement:
- 🚗 Avoid sudden starts and braking - this creates shock loads on the levers.
- 🛣️ Avoid potholes and speed bumps at low speed. Even one strong blow can break the rubber of the silent block.
- ⚖️ Don't overload the car — maximum load on the front axle Almera B10 is 950 kg. Exceeding leads to deformation of the levers.
- 🔧 Check clearances regularly in the suspension (every 20 thousand km). Early diagnosis allows you to replace silent blocks before critical wear.
It is also worth paying attention to quality of roads, on which you drive. If the machine is operated in off-road conditions or on gravel surfaces, the silent blocks wear out 2-3 times faster. In such cases it makes sense to set reinforced polyurethane bushings (for example, from Powerflex), but they are more expensive and stiffer, which affects comfort.
After replacing silent blocks, avoid sudden maneuvers and high speeds in the first 500 km. The rubber of the new parts should “grind in” to the metal.
FAQ: Frequently asked questions about silent blocks Nissan Almera Classic B10
Is it possible to drive with worn silent blocks?
Technically it is possible, but this will lead to:
- Accelerated tire wear (due to poor camber).
- Damage to the lever lugs (the entire lever will need to be replaced).
- Deterioration in handling, especially at high speed.
In case of critical wear (cracks in rubber, play more than 2 mm), the silent block may fly out of the eyelet while driving, which could result in an accident.
How long does it take to replace?
At the service station, work takes 1.5–2.5 hours on one side (depending on the condition of the threaded connections). If you replace it yourself, you will be left without any experience. 4–6 hours, since it will require combating stuck bolts and precise pressing.
Do I need to change silent blocks in pairs?
Not required, but recommended. If the silent block is worn out on only one side, replace it, but check the condition of the second. If the difference in wear is significant, this will lead to uneven camber and pull the car to the side.
Is it possible to use polyurethane silent blocks?
Yes, but with reservations:
- ✅ Pros: more durable (lifespan up to 200 thousand km), resistant to oil and chemicals.
- ❌ Cons: harder, transmit more vibrations to the body, 2-3 times more expensive.
For Almera B10 suitable polyurethane bushings from Powerflex (article PFF5-601 for front control arms). But their installation requires precise pressing, otherwise they will quickly fail.
What should I do if there is still a knocking noise after replacement?
The reasons may be as follows:
- The lever mounting bolts are loose (check the tightening torque).
- The lever eye is damaged (the lever assembly needs to be replaced).
- Other suspension elements are worn (ball joint, stabilizer link).
- The silent block is installed crookedly or is not fully pressed.
If the knocking noise does not disappear, go for diagnostics - perhaps the problem is not in the silent blocks.
