Operation Nissan Almera Classic in Russian road conditions it often leads to rapid wear of suspension elements, and one of the most vulnerable places is the rear silent block of the front control arm. This part performs the critical function of damping, dampening vibrations from uneven asphalt and preventing the transfer of shock loads to the vehicle body. When the rubber-to-metal joint loses its properties, you begin to feel knocking, vibration in the steering wheel and deterioration in handling, which makes further driving unsafe.
Many car owners mistakenly believe that replacing the lever assembly is the only solution to the problem, but in fact, competent repairs require accurate diagnosis and replacement silent block. This allows you to significantly save money and restore the factory characteristics of the suspension if the lever itself does not have cracks or severe corrosion. Understanding the design and the correct sequence of actions will help you do the work yourself or monitor the quality of services in the service.
In this article, we'll take a closer look at the signs of wear, the tools needed, and the step-by-step replacement process so you can extend the life of your undercarriage. Nissan Almera. We will pay special attention to the selection of high-quality spare parts, since the market is overflowing with counterfeit products that break down after just a few thousand kilometers.
Diagnosis of faults and signs of wear
You can understand that the rear silent block of the front lever requires immediate replacement by a number of specific symptoms that appear when driving. The first and most obvious sign is a clunking or knocking noise from the front of the suspension when driving over speed bumps or potholes. These sounds do not disappear when the load on the body changes, which distinguishes them from problems with stabilizer links.
The second important indicator is a wheel alignment violation, which cannot be consistently adjusted. If you have repeatedly gone through the procedure of adjusting the wheel alignment angles, but they quickly go astray, this is a direct signal that the rubber-metal suspension elements have play. In this case, the wheel begins to “walk” relative to the body, which leads to uneven tire wear and unstable behavior of the car on the highway.
It is also worth paying attention to the characteristic vibrations transmitted to the steering wheel and the floor of the cabin. When accelerating or braking, you may feel a vibration that gets worse as your speed increases. This is due to the fact that the deformed silent block ceases to fix the lever in the correct position, allowing it to move under load.
- 🔊 The appearance of knocks and impacts in the front suspension when driving over uneven surfaces.
- 📉 Impossibility of maintaining correct alignment angles for a long time.
- 🚗 Deterioration of directional stability and the appearance of vibrations on the steering wheel.
- 🔧 Visual inspection reveals cracks, rubber delamination or metal squeezing.
It is important not to delay repairs, since the destruction of one silent block can lead to accelerated wear of adjacent elements, including ball joints and other levers. Ignoring the problem may result in the lever simply breaking out of its seat during a sharp maneuver or emergency braking, which can lead to a serious accident.
Selection of quality spare parts: original or analogues
Spare parts market for Nissan Almera Classic offers a wide range of options, from original products to budget analogues from various manufacturers. Original marked with logo Nissan, is usually supplied complete with a lever, which makes its purchase economically unprofitable if the lever itself is intact. However, there are brands that produce exclusively silent blocks, the quality of which is not inferior to factory parts.
Among the trusted manufacturers, it is worth highlighting German companies Febi Bilstein and SWAG, as well as a Japanese brand 555 (marked Superior) and American Lemforder. These manufacturers use high-quality rubber and metal that can withstand high loads and aggressive chemical effects of reagents. Cheap analogues from China or Turkey often use low-quality rubber, which quickly hardens in the cold and cracks.
When purchasing, be sure to pay attention to the packaging and the presence of protective films on rubber surfaces. The silent block must be clearly marked and have a part number corresponding to the catalog. Feel free to ask for a quality certificate or check the product against the manufacturer’s database via a QR code or website to avoid counterfeits.

⚠️ Attention: Avoid purchasing silent blocks without packaging or with damaged protective layers. Even microcracks on the rubber surface during installation can lead to rapid destruction of the unit under load.
Tools and preparation for work
To successfully replace the silent block, you will need a set of specialized tools, since standard wrenches and screwdrivers will not do the job. The main difficulty is to press out the old worn element and press in a new one without damaging the metal holder and rubber. You will need silent block pullers or a powerful hydraulic/screw press.
In addition to the press, prepare a set of open-end and ring wrenches (sizes 17, 19, 21), ratchet heads, a torque wrench for tightening the bolts with the required force, and a pry bar. Don't forget to use a penetrating lubricant like WD-40 or similar to loosen the stuck bolts securing the arm to the body and beam. A hammer and chisel are also useful for dismantling old bushings if they cannot be pressed.
If you are working in a garage environment without a professional stand, you can use homemade tools made from bolts, nuts and thick washers. The main thing is to ensure uniform pressure on the inner bushing of the silent block when extruding. Uneven force can lead to misalignment and jamming of the part, which will make dismantling impossible without damaging the lever.

☑️ Preparation for replacing the silent block
Dismantling and installation technology
The process begins by lifting the car and removing the wheel to access the suspension. Unscrew the bolts securing the front arm to the body and beam, having previously marked their position if this is necessary for subsequent adjustment. Remove the lever and move it to a workbench where it is most convenient to work with the press.
To press out the old silent block, install the lever on special stands so that it is securely fixed. Using a mandrel that matches the diameter of the inner sleeve, apply slow pressure with a press, squeezing the rubber-metal element to the side. It is important to ensure that the force is applied strictly along the axis, otherwise the lever may be bent.
Before installing a new one silent block thoroughly clean the seat from dirt and rust. Apply a thin layer of soap solution or special lubricant to the outer surface of the new part - this will make pressing easier. Press the element all the way in, controlling its position so that it fits in smoothly and without distortion.
Once installed, the lever is returned to the vehicle and the bolts are pre-tightened. Final tightening is carried out only after the car is lowered to the ground and the wheels are loaded with the weight of the body. This is critical for the rubber elements to function properly.
Why can't you tighten bolts by weight?
If you tighten the lever mounting bolts while the car is hanging on a lift, the silent block will be in a twisted state. When lowering the car, it will begin to work in the wrong mode, which will lead to rapid destruction of the rubber and knocking noises after just a couple of thousand kilometers.
Some craftsmen use the pressing method with a hammer, but this is extremely risky and can damage the rubber. If you are not confident in your abilities, it is better to use the services of a professional service that has the necessary equipment.
⚠️ Attention: Never try to press a new silent block by hitting the rubber part directly with a hammer. This will lead to microcracks, which will appear during operation and lead to rapid failure of the part.
Before starting the pressing work, make chalk marks on the position of the silent block relative to the lever. This will help you understand how the part was originally installed and avoid mistakes when installing a new bushing if it has an asymmetrical design.
Nuances of tightening and angle adjustment
After installing the new silent block and assembling the suspension, the most crucial moment comes - the correct tightening of the fasteners. As already mentioned, the final tightening of the bolts should be done in the “on wheels” position, that is, when the car is on the ground. If you tighten them by weight, the rubber will be constantly twisted, which will cause it to wear out quickly.
Use a torque wrench to maintain factory tightening torques. For front arm mounting bolts Nissan Almera Classic these values are usually around 100-120 Nm, but it is better to check the exact numbers in the service documentation. Excessive force can damage the threads or deform the bolt, while insufficient force will lead to backlash.
After replacing the silent blocks, it is strongly recommended to visit the wheel alignment stand. Even slight movement of the control arm can change wheel alignment, affecting handling and tire wear. Adjustments must be made with the suspension loaded to avoid measurement errors.
- 📏 Tighten the bolts only after lowering the car to the ground.
- ⚙️ Use a torque wrench to control the tightening torque.
- 🎯 Be sure to undergo wheel alignment adjustment after repair.
- 🛑 Check the tightening of the bolts after 500-1000 km.
Ignoring these rules can negate all repair efforts and lead to the reappearance of knocking within a month. Proper assembly guarantees suspension durability and a comfortable ride.
Tightening the lever bolts under load is a key rule that prolongs the life of silent blocks by 2-3 times compared to tightening them by weight.
Common mistakes and expert advice
One of the most common mistakes is trying to replace the silent block without removing the lever. In conditions of a dense suspension arrangement, this is extremely inconvenient and often leads to damage to neighboring units. Removing the lever allows you to thoroughly clean the seats and ensure precision pressing.
Another mistake is using lubricants that are not intended for rubber. Some craftsmen use machine oil or grease, which leads to swelling and destruction of the rubber part. Use only special silicone lubricants or soap solution.
Also, do not neglect checking the condition of other suspension elements. Often, along with silent blocks, ball joints, stabilizer bushings and shock absorbers fail. A comprehensive inspection will save you time and money in the future.
If you notice that the lever has signs of corrosion or cracks at the welding points, replacing the silent block may not make sense. In this case, it is better to replace the lever assembly to ensure safe operation.

FAQ: Frequently asked questions about replacing silent blocks
How long does it take to replace the rear silent block of the front control arm?
On average, replacing one silent block, taking into account the removal of the lever, pressing out and installation, takes from 1 to 2 hours if professional equipment is available. In garage conditions without a press, the process can take up to 3-4 hours due to the complexity of dismantling.
Is it possible to drive with a worn silent block?
Strongly not recommended. A worn silent block changes the geometry of the suspension, which leads to unstable vehicle behavior, increased braking distance and the risk of loss of control. In addition, this causes accelerated wear of tires and other suspension components.
Do I need to change the silent blocks in pairs (on the left and right lever)?
It is advisable to change them in pairs, especially if the car has significant mileage. Rubber ages equally on both sides, and if one part has already worn out, the second will soon follow suit. This will ensure uniform suspension behavior.
What happens if you don't tighten the bolts after lowering the car?
If the bolts are tightened before the machine is lowered, the silent block will work in a tense state. This will lead to rapid destruction of the rubber, knocking noises and wheel alignment problems. Always tighten fasteners while under load.
Is it possible to use sealant when pressing in a silent block?
No, the use of sealant is not recommended as it may alter friction and cause the part to misalign when pressed. It is better to use a soap solution or a special silicone-based lubricant that does not harm the rubber.
Compliance with all recommendations and the use of high-quality spare parts will ensure reliable operation of your suspension Nissan Almera Classic for many years. Regular inspection and timely replacement of worn-out elements is the key to your safety on the roads.
