Car rear suspension Nissan Almera The new generation (G15) plays a critical role in providing comfort and controllability. The design of the multi-link rear axle uses elastic connections that dampen vibrations and shocks from the road surface. Over time, rubber-metal hinges, known as silent blocks, lose their properties due to constant exposure to loads, temperature changes and aggressive reagents.
Ignoring signs of wear leads not only to the appearance of extraneous sounds when driving, but also to disruption of wheel alignment, which increases fuel consumption and uneven tire wear. For owners Nissan Almera With the G15 body, it is especially important to carry out diagnostics on time, since the design features of the rear beam make the replacement of some elements a procedure requiring special tools.
Signs of a faulty rear silent block
You can determine that rear suspension elements require replacement based on a number of characteristic symptoms. Most often, the driver notices the appearance of dull knocks or squeaks when driving over uneven surfaces, especially at low speeds. These sounds occur because metal begins to touch metal in places where the rubber gasket should be.
The second warning sign is a change in the car's behavior on the road. If Nissan Almera has become less stable in turns, excessive rolliness appears, or the car begins to “yaw” along the trajectory when moving in a straight line, this is a direct indication of wear on the guide elements. It is also worth paying attention to uneven wear of the tire rubber on the inside or outside.
- 🔊 The appearance of dull impacts in the rear of the body when driving through potholes or speed bumps.
- 🛣️ The car pulls to the side when driving on a flat road without the steering wheel.
- 📉 Uneven tire tread wear, especially on the rear wheels.
⚠️ Warning: If you feel the steering wheel vibrating or the vehicle losing traction at high speeds, stop driving immediately until diagnosis. Ignoring the wear of silent blocks can lead to rubber rupture and instant loss of controllability.
Sometimes the problem is disguised as a malfunction of the shock absorbers, but upon careful inspection it becomes clear that the reason lies precisely in the rubber-metal joints. A visual inspection may reveal cracks, delamination of the rubber, or complete removal of the inner sleeve from the housing.
Design features and selection of spare parts
When selecting new parts for Nissan Almera G15 It is important to understand that the rear suspension consists of several types of silent blocks, each of which performs its own function. There are external and internal hinges, as well as elements connecting the arms to the body. Original parts from the manufacturer (Nissan) provide factory performance, but are often overpriced.
There are high-quality analogues on the market from trusted brands, such as Lemförder, Febi or Corteco. They often exceed the original in terms of service life due to the use of rubber that is more resistant to oil and temperature. However, it is important to avoid cheap Chinese fakes, which are destroyed within a few months of use.
Particular attention should be paid to the material from which the bushing is made. For severe operating conditions (bad roads, frequent off-road driving), some owners switch to polyurethane analogues. They are significantly stiffer than rubber, which improves handling, but can reduce comfort and increase the load on adjacent suspension elements.
- 💎 Original spare parts: maximum compatibility, but high price.
- 🛠️ High-quality analogues: optimal price-resource ratio.
- ⚙️ Polyurethane: improved dynamics, but harshness and noise.
- Original (Nissan)
- High-quality analogue (Lemförder/Keiko)
- Polyurethane (Corteco/Special)
- Cheap analogue (budget)
⚠️ Attention: Do not buy silent blocks without packaging and labeling. The absence of a protective layer on the metal and a discrepancy in size can lead to the impossibility of installation or rapid failure of even a new element.
Required tool for replacement
The process of replacing rear silent blocks with Nissan Almera does not belong to the category of simple work that can be done “on your knees”. For high-quality dismantling and installation, specialized tools are required. An ordinary jack and a set of wrenches will not help here, since considerable effort is required to squeeze out the old bushings and press in the new ones.
You will definitely need a silent block puller or a powerful hydraulic press. You will also need wrenches to unscrew the lever mounting bolts, which often stick and require treatment with penetrating lubricant. You can’t do without an inspection hole or a lift for free access to the suspension elements.
Use a torque wrench to work on bolted connections. This is critical because tightening the suspension arms to Nissan Almera G15 produced in specific modes, often with preliminary sagging under load. Violation of the tightening torque will lead to rapid destruction of new silent blocks.

☑️ Preparation for work
Step-by-step replacement instructions
The first stage of work is to lift the car and remove the rear wheels. Clear access to the rear suspension arms. If you have a crankcase protection installed, it must also be removed. Inspect the condition of the mounting bolts: if they are heavily rusted, apply liberally with penetrating lubricant and give it time to work.
Next, you need to unscrew the bolts securing the arms to the body. Be careful: the arms are under load, so use stands or a jack to support them. After removing the lever, carefully remove the old silent block. If it does not budge, use a puller, being careful not to damage the seat in the metal of the lever.
Clean the seat from dirt, rust and rubber residues. Apply a special lubricant to the new bushing (never use engine oil or lithol unless the manufacturer specifies otherwise). Press in the new silent block using a puller until it stops, controlling the installation depth.
Reinstall the lever, but do not fully tighten the bolts until the vehicle is lowered onto its wheels and the suspension is in its working position. This is necessary to prevent the rubber from twisting when driving.
The nuances of tightening the bolts of the levers
The bolts securing the arms to the body are tightened only after the car is lowered to the ground and the weight of the car presses on the suspension. If you tighten them by weight, when driving, the rubber of the silent blocks will be twisted and quickly tear.
⚠️ Attention: When pressing the silent block, make sure that the inner sleeve does not rotate relative to the body. If the bushing rotates, the suspension geometry will be disrupted and the car will ride unstably.
All rear suspension fasteners must be torqued to manufacturer specifications with the vehicle on the ground.
Parameters and compatibility table

Using data from the table will allow you to avoid selection errors. Often sellers offer universal solutions that may not fit the bushing diameter or bolt length. Always check the dimensions with the original before purchasing.
Symptoms of improper installation
Even if you have replaced the parts, the problem may persist if the work was done incorrectly. One of the most common defects is incorrect tightening of bolts. If the levers were tightened while suspended, the rubber inside the silent block becomes twisted. When driving under load, this causes rapid destruction of the rubber and the appearance of squeaks.
Another common problem is misalignment during pressing. If the silent block was installed at an angle, it will work unevenly and one side will quickly fail. It is also worth checking the condition of the levers: if the metal is deformed, replacing the silent blocks will not solve the problem with the suspension geometry.
Before starting work, be sure to photograph the location of the levers and bolts in order to accurately reproduce the assembly diagram and not confuse the location of the fasteners.
The wrong choice of lubricant can also be fatal. Some craftsmen use graphite lubricant or grease, which can corrode the rubber or cause the bushings to slip inside the body. Use only specialized compounds recommended by the rubber manufacturer.

How to check for correct tightening
Roll the car for short distances, then pick it up again. Inspect the silent blocks. If radial cracks are visible on the rubber where the bolt exits, it means that the tightening was done incorrectly or skewed.
FAQ: Frequently asked questions
Is it possible to replace silent blocks without removing the lever?
Theoretically, this is possible if you use special pullers, but in practice it is extremely inconvenient and risky. Space is limited and the risk of damaging adjacent suspension components or brake lines is very high. It is recommended to remove the lever completely for quality repairs.
How long does it take to replace rear silent blocks on a Nissan Almera G15?
If you have professional equipment and experience, the work takes from 2 to 4 hours per couple. In a garage without a press, using a puller, the process can take the whole day, especially if the bolts are stuck.
Do I need to do a wheel alignment after replacement?
Yes, definitely. Any intervention in the suspension geometry, especially the replacement of link elements, violates the wheel alignment angles. After replacing the silent blocks, you need to visit the wheel alignment stand to adjust the parameters.
What is the service life of polyurethane silent blocks?
Polyurethane analogues last much longer than rubber ones, on average 80-100 thousand kilometers, depending on operating conditions. However, they require more careful maintenance and periodic lubrication to avoid squeaks.
Is it possible to drive with a cracked silent block?
Strongly not recommended. A crack can lead to a complete rupture of the rubber at any time, especially during heavy braking or when turning. This poses a direct threat to traffic safety.
