Operation Nissan Almera Classic in Russian road conditions it often leads to premature wear of suspension elements. One of the most common problems faced by owners of this model is the failure of the front strut support bearings. This is a critical component that connects the shock absorber to the car body, and its failure directly affects handling and driving safety.
Ignoring the symptoms of a malfunction can lead to destruction of the shock absorber itself, deformation of the body cup and the appearance of extraneous noise that is difficult to eliminate without repair. In this article we will look in detail at how to properly diagnose, what tools you will need and how to replace them yourself. support bearing, saving on car service costs.
The replacement process requires certain skills in working with tools and an understanding of suspension design. However, following a clear algorithm of actions, you can do this work in a garage. It is important to approach the issue responsibly, since incorrect installation can lead to rapid re-wear of parts or problems with wheel alignment.
Symptoms of malfunction and diagnostics of the unit
Determine what support bearing requires replacement, based on a number of characteristic symptoms that appear when the car is moving. The most obvious sign is a knocking or squeaking noise from the front end, especially when going over bumps or turning the steering wheel. The sound is often heard even with the windows closed and can be localized in the area of the arch or engine compartment.
When turning the steering wheel at a standstill or at low speed, you may feel jerking or hear clicking noises. This occurs due to the fact that a failed bearing no longer ensures smooth rotation of the strut relative to the body. It is also worth paying attention to how the car behaves when braking: if the car starts to pull to the side, this may be an indirect sign of a problem with the suspension.
For an accurate diagnosis, it is not necessary to immediately disassemble the suspension. A visual inspection and test drive can be carried out. Have a helper turn the steering wheel while you listen from the wheel arches. If the knocking coincides with turning, the problem is almost certainly in the support assembly. Nissan Almera Classic has a specific front suspension design, where the load on these bearings is distributed unevenly, which accelerates their wear.
Selection of spare parts and necessary tools
Before starting work, it is necessary to prepare a high-quality set of spare parts. They are presented on the market as original parts from Nissan, as well as many analogues from trusted manufacturers. The original has a high resource, but costs much more. Among analogues, brands that specialize in suspension parts are often chosen, as they offer the best price-quality ratio.
In addition to the bearings themselves, it is strongly recommended to replace the shock absorber boot and bump stop, as they often wear out simultaneously. It is also worth checking the condition of the suspension spring: if it has traces of corrosion or cracks, it is also better to replace it. Ignoring these little things can lead to the fact that after a short time you will have to disassemble the suspension again.
To complete the work, you will need a set of tools, including a jack, supports, wrenches and specialized equipment. Without a compressor with a spring separator, it is almost impossible to remove the strut without the risk of injury or damage to parts. You will also need 12, 14, 17, 19 and 24 millimeter wrenches, as well as sockets with extensions.

Step-by-step replacement instructions
We begin the process by preparing the car. Install Nissan Almera Classic on a level surface, apply the handbrake and chock the rear wheels. Open the hood and unscrew the nuts securing the upper support to the body. There are usually three of them, and they are located under a plastic cap in the engine compartment. If the nuts are stuck, use a penetrating lubricant and give it time to work.
Then raise the front of the car using a jack and place it on secure stands. Remove the wheel. Now you need to unscrew the bolts securing the strut to the steering knuckle. They may be stuck, so carefully tap them with a hammer through a wooden spacer to avoid damaging the threads. After unscrewing the bolts, the strut should freely move away from the fist.
Remove the strut assembly from the engine compartment and move to a workbench. Here you use a separator to compress the spring. Compress the spring evenly on both sides until it releases the top support. This is a critical moment that requires the utmost caution. If the spring comes off, it could cause serious injury or damage to the tool.
☑️ Preparation for dismantling the rack
Remove the old support and bearing. Clean the spring seat from dirt and rust. Install new support bearing, making sure it is oriented correctly relative to the rack body. Then reassemble the assembly in reverse order, compressing the spring to the desired size. It is important that the spring fits into its seats without distortion.
⚠️ Attention: When tightening the shock absorber rod nut, use a second wrench to prevent the rod itself from turning. If the rod starts to rotate with the nut, you can damage the threads or the shock absorber itself.
The nuances of tightening the mounting bolts to the steering knuckle
The bolts securing the strut to the steering knuckle need to be tightened only when the vehicle is on its wheels under load. If you tighten them by weight, the rubber bushings can twist, which will lead to rapid wear and squeaking when driving.
After assembly, install the rack back onto the vehicle. Secure it to the steering knuckle, but do not tighten the bolts all the way. Lower the vehicle to the ground to allow the suspension to accept the load before fully tightening all fasteners. This will ensure the correct position of the bushings and extend the life of the unit.
Suspension fasteners should only be tightened under load when the vehicle is on its wheels to avoid distortion of the rubber elements.

Common mistakes when doing DIY repairs
One of the most common mistakes is trying to replace only the bearing, leaving the old support. Over time, the rubber of the support hardens and cracks, losing its damping properties. Installing a new bearing in an old support will not give the full effect, and the knocking may return after a few thousand kilometers. Therefore, change the assembly.
Another mistake is improperly tightening the shock absorber rod nut. If you tighten it too loosely, the support will wobble, causing a knocking noise. If you overtighten, you can break the threads or crush the rubber part of the support. Use a torque wrench to ensure the exact tightening torque specified in the technical documentation.
Also, many people forget to check the condition of the spring cup on the body. If there is deep corrosion there, the new support may not fit tightly, resulting in play and noise. In such cases, the cup must be cleaned and treated with an anti-corrosion compound before installing a new part.

The importance of wheel alignment after replacement
After replacement support bearings and removal of suspension elements, the geometry of the front axle may change. Even if you tried to align the details as accurately as possible, microshifts are inevitable. Therefore, the wheel alignment procedure is mandatory after such repairs. Ignoring this step will result in uneven tire wear and poor handling.
On Nissan Almera Classic The camber and toe adjustment is carried out by changing the length of the steering rods and turning the lower arms (in some modifications). Professional equipment will allow you to accurately set the angles, ensuring straight movement of the car and long service life of the rubber.
If you notice that the steering wheel is crooked or the car pulls to the side even after replacing the bearings, this is a sure sign that the wheel alignment angles are broken. In this case, do not delay your visit to the wheel alignment service center, as driving with broken geometry is dangerous.
⚠️ Attention: Replacing support bearings without subsequent wheel alignment adjustment can lead to accelerated tire wear by up to 50% in the first 5,000 kilometers.
Before going to the wheel alignment stand, make sure that the tire pressure corresponds to the standard indicated on the sticker in the doorway. This is critical for measurement accuracy.
FAQ: Frequently asked questions
Is it possible to drive with a faulty support bearing?
Technically possible, but highly not recommended. Bearing wear results in shock loads on the body and strut, which can cause destruction of the shock absorber or deformation of the spring cup. In addition, it worsens the car's handling.
How long does it take to replace support bearings?
If you have a separator and experience working with suspension, replacing one strut takes about 40-60 minutes. It will take approximately 2-3 hours to completely replace both bearings with preparation and assembly. Without a separator, the time can increase significantly due to the need to look for alternative methods of compressing springs.
Do I need to replace both bearings at once?
Yes, it is highly recommended to replace them in pairs, even if the second one is not knocking yet. Parts wear out synchronously, and the old bearing may fail a short time after replacing the first one. This will also save time on re-disassembling the suspension.
Is it possible to replace just the bearing without changing the support?
This is theoretically possible, but in practice it is not recommended. The rubber part of the support loses its elasticity over time, and installing a new bearing in the old support will not give the desired effect. It is better to change the assembly to ensure the quality of the repair.
What tools are required to be replaced?
The most important tool is a separator (compressor) for compressing the springs. Without it, it is almost impossible to safely disassemble the rack. You will also need a standard set of wrenches, a jack, stands and penetrating lubricant for unscrewing stuck bolts.
