Many sedan owners Nissan Almera Classic pay maximum attention to the appearance of the body, the condition of the interior and the operation of the engine, completely ignoring the lower part of the car. However, it is the underbody and suspension that are the foundation that determines handling, comfort and safety when driving on Russian roads. Despite the fact that the model is considered budget-friendly and simple, its bottom design has its own unique features that every car owner should study.
Visual inspection from below allows you to identify corrosion in the early stages and assess wear of elements pendants and check the integrity of the fuel lines. Often, problems with handling or extraneous sounds arise precisely because of hidden defects that can only be noticed when lifting the car onto a lift or inspection hole. Ignoring this aspect of maintenance can result in costly repairs.
In this article we will analyze the device in detail Almera Classic below, paying attention to key nodes, typical “diseases” and recommendations for protection. You will learn what to look for when buying a used one and how to extend the life of the bottom in a hostile environment.
Design features of the front suspension
Front Nissan Almera Classic equipped with classic McPherson, which is standard for cars in this class. The design is simple, but provides a decent balance between comfort and handling. The shock-absorbing struts here are non-separable, which simplifies the design, but complicates repairs if they fail.
The strut is attached from above to the body through a support bearing, and from below to the steering knuckle through ball joints. It is important to regularly check the condition of the shock absorber boots, as their damage leads to rapid failure of the entire strut. Anthers protect the stem from dirt and moisture, and replacing them costs a penny, but saving here is unacceptable.
The suspension arms are made of steel and have spherical joints. When inspecting from below, pay attention to the presence of cracks on the levers and the condition of the silent blocks. The destruction of rubber-metal joints leads to backlash, which is felt when driving over uneven surfaces and worsens directional stability.
Particular attention should be paid anti-roll bar. Its bushings and struts (bones) are consumables and require replacement every 30-50 thousand kilometers, depending on operating conditions. If you hear a knocking sound when passing speed bumps, the problem most often lies here.
Rear suspension and its operation
In the back Nissan Almera Classic a semi-independent type beam is installed, which is typical for many budget sedans. This design is highly reliable and unpretentious. Shock absorbers are located separately from the springs, which simplifies their diagnosis and replacement.
One of the weak points of the rear beam is the corrosion of the shock absorber mounts. Often the rubber bands of the upper mounts rot, and the shock absorber begins to dangle, making characteristic sounds. Regular inspection of these components will help avoid loss of controllability on the rear axle.
The rear suspension springs can lose their elasticity over time, which leads to the car sagging. This is especially noticeable if the machine is often used with a full load. Springs It is also worth inspecting for cracks, especially in the lower turns.
The silent blocks of the rear beam connecting it to the body are also subject to wear. When they are destroyed, a noticeable play appears, which can lead to deformation of the body during sudden maneuvers. Replacing these elements requires special pressing equipment.

Exhaust system
Exhaust system Almera Classic consists of a downpipe, catalytic converter, middle section and muffler. The system is attached to the body through rubber hangers, which dry out and tear over time. This causes the muffler to hit the underbody, creating a loud noise and damaging the insulation.
The catalytic converter is located immediately after the exhaust pipe. Its condition directly affects the environmental friendliness of the exhaust and engine performance. When the catalyst fails, an error often occurs in the oxygen sensor, which requires replacing or reflashing the ECU.
It is important to check the tightness of pipe connections. Exhaust gas leaks in the manifold or downpipe area are hazardous to health, as carbon monoxide can enter the cabin through the vents. Tightness systems are a safety issue, not just an environmental issue.
Exhaust system rust is a common occurrence, especially around welds. If you see through corrosion, it is better not to delay replacement, since a pipe rupture can occur at any time, especially when driving over uneven surfaces.
Fuel system and protection elements
Fuel tank Nissan Almera Classic located under the rear seat and attached to the bottom with metal clamps. When inspecting from below, you need to make sure there are no fuel leaks and the integrity of the fuel lines. Fuel pipes run along the bottom and are protected by plastic covers, which are often damaged by stones.
The fine fuel filter is built into the fuel pump, so access to it from below is limited. However, it is important to monitor the condition of the fuel tank, as it is susceptible to corrosion. The inside of the tank may be covered with rust, which clogs the filter.
The engine oil pan is the most vulnerable element when driving off-road. As standard, the crankcase guard is often missing or made of thin plastic that does not withstand impacts. Metal protection crankcase is a mandatory accessory for Russian conditions.
It is also worth paying attention to the condition of the fuel tank fastenings. Rubber suspensions lose elasticity over time, and the tank begins to wobble, which can lead to breakage of fuel lines during strong shaking.

Typical corrosion problems and how to fix them
Corrosion is the main enemy of any car, and Almera Classic no exception. Thresholds, arches and the bottom are especially vulnerable in places where dirt and moisture accumulate. Corrosion often starts from the inside and may not be noticed from the outside until the metal becomes loose.
Pay special attention to the suspension mounting points and exhaust system brackets. These elements experience constant vibration, which accelerates the destruction of the paintwork. Anti-corrosion treatment should be a regular procedure.
If you find pockets of rust, they must be immediately cleaned and treated with a rust converter. Ignoring the problem will lead to through holes, the repair of which will cost much more.
For prevention, it is recommended to use modern mastics and anti-gravel coatings. They create a protective barrier that prevents moisture and salt from reaching the metal.
Wear resistance table of main components
Below is a table showing the approximate service life of the main suspension components and underbody during operation in normal urban conditions. This data will help you plan preventive maintenance.
| Car assembly | Approximate resource (km) | Symptoms of wear | Recommendation |
|---|---|---|---|
| Front shock absorbers | 80 000 - 100 000 | Impacts, knocking, oil leaks | Replacement assembly |
| Rear shock absorbers | 100 000 - 120 000 | Knocking, body sagging | Replacement in pairs |
| Silent blocks of levers | 60 000 - 80 000 | Play, squeaks, uneven tire wear | Replacement or repair |
| Stabilizer links | 30 000 - 50 000 | Knock when driving over bumps | Replacement |
| CV boots | 20 000 - 40 000 | Loss of tightness, leakage of lubricant | Urgent replacement |
⚠️ Attention! If you notice oil leaks on your shock absorbers, do not delay replacing them. Operating with faulty shock absorbers increases braking distance and can lead to loss of control on wet roads.
What to do if corrosion is detected?
First, loose metal must be mechanically removed to a solid base. Then treat the surface with a rust converter, prime and paint. To enhance protection, you can apply mastic. Do not try to weld a through hole without preliminary preparation, as the metal around the hole will quickly burn through.
Recommendations for underbody protection
For maximum protection Nissan Almera Classic It is recommended to install a metal engine sump. The plastic protection that comes from the factory does not withstand impacts from large stones and does not protect against aggressive reagents. A metal sheet with a thickness of 2 mm will reliably cover the crankcase and gearbox.
Regular underbody washing in winter also plays an important role. Wash off salt and dirt, especially after driving on the highway, where the concentration of reagents is maximum. Use a pressure washer, but be careful not to damage the protective coatings.
After each wash, it is advisable to treat hard-to-reach areas with anti-corrosion compounds. This can be done using special sprayers or by visiting specialized services. Regularity — the key to a long life of the body.
Do not forget to inspect the condition of the plastic arch protection elements. If they are damaged, they must be replaced, since holes in the arches will allow water and dirt to enter the engine compartment and onto the body.
When installing metal crankcase protection, be sure to provide technological openings for access to the engine drain plug and oil filter. Otherwise, each maintenance will turn into a complex operation to dismantle the protection.
⚠️ Attention! Never use self-tapping screws to attach metal protection without rubber gaskets. Metal on metal is a guarantee that the protection will begin to creak and quickly rust at the attachment points due to electrochemical corrosion.
Comprehensive underbody protection includes the installation of a metal pan, regular anti-corrosion treatment and timely replacement of worn suspension elements.
Conclusion and final recommendations
Inspection Nissan Almera Classic below is not just a formality, but a necessity to extend the life of the car. The simple suspension design and availability of spare parts make this car easy to maintain, but only with regular condition monitoring.
Ignoring minor problems, such as a cracked boot or a weak muffler hanger, can lead to serious damage. Remember that prevention is always cheaper than repairs. Visit the service regularly or carry out the inspection yourself using a lift or pit.
By following these tips, you can keep your car in excellent condition and avoid unexpected expenses. Almera Classic deserves attention, and proper care of its lower part will guarantee reliability for many years.
How often should you inspect the underbody of your car?
It is recommended to carry out a visual inspection of the underbody and suspension at least once every 10,000 kilometers, as well as after each off-road trip or heavy rainfall.
What to do if severe corrosion is detected on the thresholds?
You need to contact a body repair specialist. Do-it-yourself welding often leads to metal deformation and further spread of rust. Requires complete cleaning, processing and restoration of geometry.
Is it possible to drive with faulty stabilizer links?
Technically possible, but highly not recommended. This worsens the car's handling, increases roll when cornering and creates additional stress on other suspension elements, accelerating their wear.
Which crankcase protection is better: steel or aluminum?
Steel protection is stronger and absorbs impacts better, but is heavier and susceptible to corrosion. Aluminum is lighter and does not rust, but can become deformed if subjected to a strong impact. For Almera Classic the optimal choice is steel with a thickness of 2 mm or more.
Where is the oil filter located on Nissan Almera Classic?
The oil filter is located at the bottom of the engine, on the front wheel side (usually on the right). It is accessible from below, but is often covered by a protective tray that must be removed or accessed through a service opening.
⚠️ Attention! When inspecting a vehicle on a lift, be sure to ensure that it is securely secured and that the locks are engaged. Working under a car without reliable fixation poses a mortal danger for the technician.
