Car suspension Nissan Almera Classic is one of the busiest nodes, especially on Russian roads. Among all the suspension elements, it is front shock absorber support often becomes a source of unpleasant sounds and controllability problems. This unit connects the shock absorber to the car body, ensuring smooth ride and proper operation of the mechanism.
Many owners Nissan Almera Classic encounter a characteristic knocking sound when driving over uneven surfaces, which is mistakenly attributed to the shock absorbers or levers themselves. In fact, most often the problem lies in the destruction of the rubber damper of the support or wear of the bearing. Ignoring a knock in the front suspension can lead to destruction of the body shell and costly repairs.Therefore, diagnosis and timely replacement are critical for safety.
Design and purpose of shock absorber support
To understand why this element fails, it is necessary to consider its structure. The support is a complex part consisting of a metal body, rubber-metal damper and built-in plain bearing or rolling. The main function of the unit is to dampen vibrations from the shock absorber and transfer them to the body without compromising passenger comfort.
B Nissan Almera Classic The front mount performs another important task - it allows the shock absorber to rotate when the steering wheel is turned. This is ensured by a bearing built into the top of the support. If the bearing sours or collapses, the steering wheel may become stiff, and a characteristic creaking or clicking sound may occur when turning.
The rubber support element operates under conditions of constant compression and tension. Over time, rubber loses its elastic properties, cracks and begins to deteriorate. As a result, the metal part of the shock absorber begins to contact the body directly, which causes strong shocks and noise.
Main symptoms of a malfunction
The problem can be determined not only by sounds, but also by changes in the car’s behavior on the road. The most obvious symptom is a dull knocking sound in the area of the front wheels when driving over speed bumps or potholes. If you only hear this sound on one side, the problem is located there.
- 🔊 The appearance of a squeak or crunch when turning the steering wheel in place or in motion.
- 🚗 Controllability deteriorates, the car begins to “float” at high speeds.
- 🛑 Uneven tire wear, especially on the inside.
Drivers often confuse the symptoms of bearing wear with a malfunction of the shock absorbers themselves. However, if the support is faulty, the shock absorber may work normally, but due to the lack of damping, shocks are transmitted harshly. It is also worth paying attention to how the car behaves when braking - there may be a roll or sway.
A visual inspection may also provide a clue. If you are able to jack up the car, look at the top of the shock absorber. Rubber breaks, oil traces or deformation of the metal cup indicate that the unit requires immediate replacement.
Selection of original parts and analogues
When choosing a new support for Nissan Almera Classic It is important to consider that there are several manufacturers offering quality alternatives to the original. The original part has a catalog number, but its cost is often inflated. There are reliable brands on the market that have proven themselves to be excellent substitutes.
Among the popular analogues are companies Febest, SNR and KAYABA. These manufacturers use quality materials for rubber inserts and bearings, which ensures long service life. You shouldn’t save money by buying cheap Chinese copies, as they often break down after just a few thousand kilometers.
When purchasing, be sure to check the integrity of the packaging and the presence of protective films on metal parts. The rubber part must be free of cracks and signs of delamination. If you plan to change the supports, it is wise to immediately purchase new ones fastening nuts and bolts, since old ones often stick and can break during dismantling.

⚠️ Attention: When purchasing a support, be sure to check the bearing compatibility. On Nissan Almera Classic Different types of supports are used depending on the year of manufacture and engine type. Make sure the bearing rotates smoothly and without play before installation.
Preparation for replacement and necessary tools
Replacing a front shock mount is a task that requires a certain level of training and tools. You do not have to contact the service if you have a garage and minimal plumbing skills. However, working with the suspension requires care and compliance with safety precautions.
You will need a set of wrenches, including sockets 14, 17 and 19. You will also need a special puller for the suspension springs, since compressing the spring without it is extremely dangerous. The presence of a jack and reliable stands is mandatory to secure the car in a raised state.
- 🔧 A set of socket and open-end wrenches (including extensions).
- 🛠 Puller for suspension springs (required!).
- 💨 Balloon wrench and jack.
- 🌊 Penetrating lubricant (WD-40) for treating rusty threaded connections.
Before starting work, it is recommended to treat all fastening bolts with penetrating lubricant and wait 10-15 minutes. This will make unscrewing them much easier, especially if the car was operated in winter using reagents. Also prepare a place to store the removed parts so that nothing is lost.
☑️ Preparation for replacing the support
Step-by-step replacement instructions
The replacement process begins with dismantling the wheel and removing the hub. Unscrew the hub mounting nut and remove the caliper, hanging it on a wire so as not to damage the brake hose. After this, unscrew the bolts securing the strut to the steering knuckle and remove the shock absorber from the eye.
The most important step is removing the spring from the shock absorber. Use a puller to compress the spring, then remove the shock absorber rod nut. Important: do not release the spring remover until the new support is fully installed. After removing the old support, clean the rod of dirt and rust so that the new part will sit smoothly.
Install the new support, ensuring the correct position of the bearing relative to the vehicle body. Typically, the mark on the support should face forward or toward the wheel, depending on the model. Reassemble the assembly in reverse order, tightening the stem nut to the recommended torque.
⚠️ Warning: Never try to compress the spring with a screwdriver or hammer! This may cause injury and damage to the spring. Use only a professional puller and wear safety glasses.
Features of tightening the rod nut
The shock absorber rod nut should only be tightened after the mount is installed on the vehicle and the wheel is lowered to the ground. If you tighten it by weight, when driving, additional stress will arise in the rubber part of the support, which will lead to its rapid failure.
Installation features and adjustment
After installing new supports, you need to check that they are installed correctly. Make sure that the spring sits in its seats without distortion. Any displacement of the spring can lead to it jumping off during movement, which is extremely dangerous.
All suspension bolts must be tightened to a specific torque. For Nissan Almera Classic The tightening torque for the shock absorber rod nut is usually approx. 60-70 Nm, and the bolts securing the strut to the steering knuckle - 100-120 Nm. Use a torque wrench for precise work.
After replacing the supports, be sure to perform a wheel alignment. Even the slightest displacement of the suspension elements can disrupt the wheel alignment angles, which will lead to rapid tire wear and deterioration in handling. Do not neglect this step, as it guarantees safe operation.
Correctly tightening the shock absorber rod nut only after lowering the wheel to the ground is the key to the long life of the new support.
Common mistakes when replacing
Many car owners make common mistakes when trying to save time or money. One of the most common mistakes is replacing only one support. If one is worn out, it means that the second one is in the same condition and will soon fail. It is better to change a pair at once so that the suspension works symmetrically.
Another mistake is using old bolts and nuts. The suspension fasteners are subjected to enormous loads, and during dismantling the threads are often stretched or the head is cut off. Installing new fasteners is a guarantee of the reliability of your repair.
You should also avoid installing supports without checking the bearing. Sometimes the bearing is included with the support separately, and it must be installed correctly. If the bearing is installed misaligned, it will quickly sour and begin to make noise.
Before starting work, take a photograph of the location of the marks on the old supports and springs - this will help to correctly install the new parts without errors in orientation.
⚠️ Attention: Do not use an impact wrench to unscrew the shock absorber rod nut! The rod may spin along with the nut, which will damage the threads and make it impossible to install a new part.
Diagnostics and condition monitoring
Even after a successful replacement, it is important to periodically check the condition of the suspension. Regular inspection will allow you to notice signs of wear in time and prevent serious damage. Owners Nissan Almera Classic It is recommended to check the supports every 15-20 thousand kilometers.
Pay attention to any unusual sounds when driving on uneven roads. If you hear new knocks or squeaks, do not delay diagnosis. Identifying the problem early will save you money and stress in the future.
It is also useful to check the condition of the rubber support elements visually. Cracks, tears or traces of oil on the rubber indicate that the part requires replacement. Do not wait until the support is completely destroyed, as this may damage the body shell.
