Car Nissan Almera Classic is famous for its unpretentiousness and availability of spare parts, but the suspension of this model often becomes a source of concern for owners. One of the most critical nodes that requires regular attention is front strut support. It is this element that connects the shock absorber to the body, taking on all the loads from road irregularities and ensuring a smooth ride.
Many car owners mistakenly believe that knocking in the suspension means the need to completely replace the shock absorber. In fact, most often the problem lies in the destruction of the support bearing or deformation of the upper bowl. Ignoring these symptoms will lead to accelerated tire wear, poor wheel alignment and, ultimately, loss of control at high speeds.
Design features and purpose of the unit
Support cup assembly for Nissan Almera Classic is a complex mechanism consisting of several elements. At the top there is bearing, which allows the post to rotate when the steering wheel is turned, providing precise control. Below is a rubber cushion designed to dampen vibrations and noise transmitted from the body to the suspension.
The reliability of the design directly depends on the quality of the materials. Factory parts are often made using high-quality rubber, which eventually hardens and cracks. In cheap analogues, the rubber can peel off from the metal body after 20-30 thousand kilometers. That's why diagnostics should be carried out comprehensively, taking into account the condition of both the metal and elastic elements.
It is important to understand that the front support operates under extreme conditions. It constantly experiences variable loads: from the static weight of the car to dynamic shocks when hitting potholes. Any crack in the rubber part or play in the bearing disrupts the geometry of the suspension. This leads to the wheel starting to work incorrectly, which affects driving safety.
The main symptoms of a malfunctioning rack support
You can recognize the problem even before visiting the service center. The first and most obvious symptom is a characteristic knocking sound when driving over bumps, especially at low speeds. If you hear a thud in the area of the front wheels when passing speed bumps, most likely support bearing has significant wear.
The second important sign is a creaking or grinding sound when turning the steering wheel in place or at low speed. This indicates that the bearing is jammed or the support is misaligned. In such cases, the steering wheel may turn with force, returning to its original position reluctantly. These sounds should not be confused with the creaking of the stabilizer, which has a different localization and character.
- 🔊 The appearance of extraneous sounds (knocking, clicking) when driving over uneven surfaces.
- 🚗 Increased effort on the steering wheel when rotating, especially when standing.
- 📉 Impaired wheel alignment, which quickly goes astray after replacing other suspension elements.
Sometimes the problem manifests itself visually. Having examined the engine compartment, you can see that top cup shows signs of corrosion or deformation. The rubber part may be dented or have deep cracks. In advanced cases, the metal part of the support can even rub the body, which is dangerous for the integrity of the paintwork and metal structure.
Selection of spare parts: original or analogue?
The auto parts market offers many options for Nissan Almera Classic. Official original number often has a high cost, which forces drivers to look for alternatives. However, saving on such an important detail as a support can result in repeated repairs in a short period of time.
High-quality analogues from trusted brands often exceed the original in terms of service life. German and Japanese manufacturers use harder rubber and improved bearings. It is important not to fall for a fake, since there are a lot of counterfeit products on the market that cannot withstand even 10 thousand kilometers. Always check the packaging and the presence of security holograms.

Front support replacement technology
Replacement process shock absorber mounts requires special equipment and certain skills. Replacing it yourself is possible, but doing it without compressing the springs is extremely dangerous. The suspension spring is under enormous tension and, if dismantled incorrectly, can break out with great force.
First you need to lift the car on a lift or jack and remove the wheel. Then you need to unscrew the nuts securing the strut to the steering knuckle. The next step is to remove the upper support from the engine compartment. Here it is important to remember or mark the position of the support relative to the body so as not to disturb the wheel alignment angles.
☑️ Preparation for replacement
The most crucial moment is removing the spring from the old rack and installing it on a new support. Use a special spring compression stand. Spring compression should be even on both sides to avoid damaging the threads or threads of the support. After installing a new part, you need to check that there are no distortions.
After assembling the unit on the car, it is important not to forget to tighten all the bolts to the required torque. This is especially true for the shock absorber rod nut, which is often forgotten to be completely tightened while the strut is under load. This can lead to rapid thread failure.
What to do if there is no stand for springs?
Without special equipment, changing the support assembly is extremely dangerous. You can try to replace only the bearing if it is removed separately, but this is labor-intensive and requires precise selection of tools. It's better to contact the service.
Diagnostics and testing after installation
After replacing the supports, it is necessary to carefully check the operation of the suspension. Drive on rough roads and listen for new knocking noises. The steering wheel should rotate easily and without play. If the knocking noise remains, perhaps the problem is not only in the support, but also in the shock absorber itself or the silent blocks of the levers.
A mandatory step is wheel alignment. Replacing the support inevitably changes the suspension geometry, so the wheel alignment angles are off. Wheel alignment must be done immediately after replacement, otherwise the rubber may wear off unevenly in just a couple of thousand kilometers.
- 🛠️ Check the tightness of all bolts securing the strut to the body and arm.
- 🎯 Get a wheel alignment done on a professional stand.
- 🔍 Inspect the shock absorber boot for damage during assembly.
Replacing the front strut support always requires subsequent correction of the wheel alignment angles, otherwise tire wear will become critical in the shortest possible time.
Common mistakes when repairing suspension
One of the most common mistakes is replacing only the bearing, without replacing the rubber cushion. Over time, rubber hardens and loses its shock-absorbing properties, which leads to metal hitting metal. Even a new bearing will not save the situation if rubber insert destroyed.
Another mistake is using a lubricant that is not intended for car suspension. Regular lithium oil may corrode rubber or leak at high temperatures. Use only special lubricants for hub and support bearings that are resistant to water and temperature changes.
Sometimes craftsmen forget to replace locking rings or nuts. It is better to replace fasteners, especially those that cause shear and vibration, with new ones. Reusing old nuts may result in them unscrewing during use.
Before starting work, be sure to clean the threaded connections from dirt and rust. Use penetrating lubricant 10-15 minutes before unscrewing to avoid thread stripping.
⚠️ Attention! Never try to compress a suspension spring “in weight” without a special stand. This is fatal and may result in serious injury or vehicle damage.
Service life and prevention
Average life of the front support per Nissan Almera Classic is about 60-80 thousand kilometers. However, this indicator strongly depends on operating conditions. Under the conditions of our roads, with their potholes and curbs, the resource can be halved. Regular inspection of the suspension at every maintenance will help identify the problem at an early stage.
Prevention includes periodically checking the condition of the shock absorber boots. If the boot is torn, dirt and moisture enter the support bearing, causing it to wear out quickly. Timely replacement of the boot can extend the life of the entire strut by tens of thousands of kilometers.
It is also important to monitor the condition of your tires. Uneven tire wear often indicates suspension problems, including faulty mounts. If you notice that the rubber wears off on one side faster than the other, this is a reason to check wheel alignment angles and the condition of the support bearings.
FAQ: Frequently asked questions
Is it possible to drive with a faulty front strut?
Technically yes, but it is highly discouraged. Driving with a broken support leads to accelerated wear of other suspension elements, disruption of wheel alignment and deterioration of vehicle handling, which creates a safety hazard.
Do I need to replace both supports at once?
Preferably. If one support is worn out, the second is most likely in a similar condition. Replacing both mounts at the same time ensures uniform suspension operation and eliminates the need for repeated repairs after a short mileage.
What tool is needed to replace the support?
You will need a jack, a wheel wrench, a set of sockets (including a 19 and 17 wrench), a torque wrench and, most importantly, a spring compression tester. Without a stand, complete replacement is impossible.
How to distinguish the knock of a support from the knock of a shock absorber?
The knock of the support is usually heard when turning the steering wheel or when driving over bumps at low speed and is localized higher, closer to the engine compartment. The knock of the shock absorber itself is more often heard when driving through large holes and comes from the wheel.
Does replacing the support affect fuel consumption?
Not directly, but indirectly - yes. A broken mount disrupts suspension geometry, which increases rolling resistance and can lead to uneven tire wear, which in turn increases fuel consumption.
