Many owners Nissan Almera Classic encounter an unpleasant phenomenon when, after a short mileage, the car begins to shake at idle, and when you press the gas sharply, strong shocks are felt in the body. Often, inexperienced car owners try to look for the cause in the ignition system or fuel equipment, spending money on unnecessary spare parts, although the root of the problem lies much deeper and simpler.
The essence of the problem lies in destruction engine mounts — special dampers that hold the power unit and dampen its vibrations. On model with engine Q12 With a volume of 1.6 liters, these elements experience enormous loads due to the specific design of the suspension and the nature of the engine’s operation. Ignoring this malfunction can lead to expensive transmission repairs or ruptured cooling system hoses.
In this article, we will analyze in detail which supports fail most often, how to independently diagnose them without a lift, and how much a high-quality replacement costs. You will learn why cheap analogues can last only a couple of months and how to choose the right spare parts for the long-term operation of your car.
Design features of engine mounts on Nissan Almera Classic
Power unit mounting system Nissan Almera Classic has its own unique features that distinguish it from many other cars in the budget segment. The classic three-point mounting scheme is used here, where the two front mounts take the main load during starts and braking, and the rear mount (often called the “bone”) keeps the engine from moving backwards.
The main problem with the design is that the rubber from which the dampers are made loses its elastic properties over time. Under the influence of temperature changes, oil and road chemicals, the material begins to crack and crumble. Hydraulic cushion engine, which is installed on some versions, contains a special liquid inside to better dampen vibrations, and its rupture leads to the immediate appearance of severe shaking.
It is important to understand that Nissan Almera Classic There is no way to easily adjust the rigidity of the supports. If the rubber element is deformed, it is impossible to restore it - a complete replacement of the unit is required. A special feature of the front supports is the presence of a metal base, which is attached to the body, and a rubber part connected to the engine bracket.
Many owners wonder why original spare parts last less than expected. The fact is that the factory engine mounts They have balanced rigidity, which is comfortable for the city, but wears out quickly with aggressive driving or frequent slipping. For more severe operating conditions, you often have to look for reinforced analogues or change the kit more often.
Diagnostics of faults: how to understand that it is time to change pillows
You can determine the wear of the supports not only by visual signs, but also by the characteristic sensations during movement. The first and most reliable symptom is the appearance of strong vibration on the steering wheel and pedals when the engine is running in idle mode, especially if you are standing at a traffic light in D (Drive) with the air conditioner on.
When suddenly starting from a stop or braking, the engine may make a sharp jerk, which feels like a blow to the body. In such cases, a dull metallic knock is often heard under the hood. If you hear a creaking or clicking sound from under the hood when you press the gas, this is a sure sign that the rubber part of the support destroyed and metal rubs against metal.
A visual inspection requires an inspection hole or lift. You need to carefully inspect each support for rubber breaks, housing subsidence, or hydraulic fluid leaks. Sometimes the detachment occurs not in the center, but along the edge of the fastener, which makes diagnosis more difficult without the use of a special flashlight.
There is a simple verification method that you can do yourself. Stop the engine, open the hood and have a helper take the wheel. Shift into gear and step on the gas while holding the brake. At this moment, watch the engine: if it jumps more than 1-2 centimeters relative to its normal position, it means the pillow can't handle it with load.
⚠️ Attention: When diagnosing with an assistant, be extremely careful. Make sure the vehicle is securely in place with the handbrake on and in
PorNbefore starting the test to prevent accidental movement of the machine.

Step-by-step instructions for replacing the front supports
Replacing front engine mounts with Nissan Almera Classic - the task is doable even in a garage, but it requires a jack and support, since the engine will need to be lifted a little to remove the load from the mounts. The process begins with preparing the car: turn off the engine, open the hood and disconnect the negative battery terminal for safety.
The first step is to remove the decorative plastic engine protection and, if necessary, part of the air intake to gain free access to the upper part of the supports. You will need a set of wrenches, including a socket for 14 and 17, as well as a wrench to create force, since the bolts often stick.
First, loosen the bolts securing the support to the body, but do not unscrew them completely. Then place a jack under the engine sump (be sure to use a wooden plank to avoid damaging the crankcase) and lift the engine slightly so that the weight does not put pressure on the old support. Now you can completely unscrew the bolts and remove the old part.
Installation of the new support is carried out in the reverse order. It is important not to tighten the body bolts immediately until the engine is lowered to its normal position. First, tighten them by hand, lower the jack, let the engine sit in a new place, and only after that do the final tightening with the required force.
☑️ Preparation for replacing supports
Selection of spare parts: original versus analogues
There is a huge selection of options on the auto parts market for Nissan Almera Classic, and it’s easy for a beginner to get confused about brands. Original pillows have a catalog number starting with the prefix 11201 or 11202, and are usually supplied in original Nissan packaging. They provide the perfect balance of comfort and durability, but are often overpriced due to dealer markups.
The most popular analogues are brands Febest and 555. Products Febest often offers softer tires, which is comfortable for the city, but can wear out faster during aggressive driving. Brands 555 and Patron offer stiffer solutions that can withstand greater loads but transmit more vibrations into the cabin.
When choosing, you should pay attention to the integrity of the packaging and the quality of the rubber. If you see that the rubber on the sample in the box is already cracked or has an uneven surface, this is a reason to refuse the purchase. Hydraulic supports must be absolutely tight, without traces of oil or liquid leaks.
Some owners prefer to install reinforced mounts from brands that specialize in suspension tuning. Such parts often have a metal frame inside the rubber, which significantly increases their service life, but makes the ride harsher. This is a compromise solution for those who often drive on bad roads or carry heavy loads.
What are the dangers of installing cheap Chinese counterfeits?
Cheap fakes made from unknown raw materials can fall apart after just 1000 km. The rubber loses its elasticity, cracks and causes the engine to hit the body, which can damage the exhaust system mounts or cooling radiators.
Cost of work and common mistakes when replacing
If you decide to contact the service, the cost of replacing all four supports (two front, one rear and gearbox cushion) usually varies between 3,000–5,000 rubles, depending on the region and the status of the service station. This price includes labor, but not the cost of spare parts. If you change only the front supports, the price will be lower, but the efficiency will be less, since the load will be distributed unevenly.
Replacing it yourself can save a significant amount, but requires care. One of the most common mistakes is improperly tightening bolts. If they are tightened too much before the engine is lowered, the mount will be under constant tension and will quickly collapse. If you tighten it loosely, the engine will dangle, which will lead to vibrations.
Another common mistake is replacing only one pillow. If one of the supports collapses, it means that the others have also exhausted their service life. Replacement with a kit - this is the only right solution to avoid a second visit to the ski lift in a couple of months. Skimping on one part can lead to engine misalignment and damage to other components.
The table below shows approximate prices for popular spare parts options for front bearings:
| Manufacturer | Product type | Approximate price range (RUB) |
|---|---|---|
| Nissan (Original) | Front support | 4500 – 6000 |
| Febest | Front support | 1800 – 2500 |
| 555 | Front support | 1500 – 2200 |
| Patron | Front support | 1200 – 1800 |
⚠️ Warning: Do not attempt to use sealant or glue to repair cracks in the cushion rubber. This is ineffective and dangerous, since under load the glue will not withstand the tension, and the support will collapse at the most inopportune moment.
Before purchasing new supports, take photographs of the old bolts and fasteners so as not to mix them up during installation. Sometimes the bolts have different lengths or thread pitches, which is critical for secure fastening.
Care and prevention of destruction of supports
To extend the life of new supports, it is necessary to regularly inspect their condition, at least once every six months. Pay special attention to the condition of the rubber elements and the presence of oil leaks from the engine, since the technical fluid has an aggressive effect on the rubber, causing it to swell and destroy.
Avoid sudden starts and aggressive driving, especially in cold weather. In cold weather, rubber becomes harder and more fragile, and sudden jerks can lead to instant rupture of the damper. Allow the engine to warm up to operating temperature before accelerating vigorously.
Timely replacement of worn silent blocks of suspension arms also indirectly affects the service life of engine mounts. If the suspension has play, then all impacts from the road are transferred to the body and engine, increasing the load on the supports. Integrated approach to suspension maintenance will help save on replacing supports in the future.
Use only high-quality motor oils and ensure the tightness of engine gaskets. Oil leaks are the main enemy of rubber products. If you notice an oil stain on the cushion, immediately repair the cause of the leak and replace the damaged part, even if it appears intact.
Regular visual inspection and repair of oil leaks is the best way to prolong the life of your engine mounts and avoid costly transmission repairs.
FAQ: Frequently asked questions about engine mounts
Is it possible to drive with one broken engine mount?
Technically it is possible to drive, but it is highly not recommended. The engine will shift with each gear change and throttle application, which can cause hoses to break, radiator damage, or other mountings to fail. Vibration also has a destructive effect on body parts.
How long does it take to replace all the supports?
An experienced technician will spend about 1.5–2 hours replacing all engine and gearbox mounts. In garage conditions without experience, the process may take 3-4 hours, especially if the bolts are stuck and require pre-treatment with penetrating lubricant.
Is it necessary to do a wheel alignment after replacing the pillows?
No, replacing engine mounts does not affect wheel alignment. Wheel alignment is only required after work affecting suspension components such as control arms, stabilizer links or steering links.
Why did the vibration not disappear after replacing the pillows?
Vibration may persist if low-quality parts were installed, bolts were not tightened correctly, or if the problem lies in other components: exhaust manifold supports, transmission brackets, or flywheel imbalance.
⚠️ Attention: If vibration remains after replacing the supports, check the condition of the exhaust manifold supports. On Nissan Almera Classic they often fail before the engine mounts and create similar symptoms.
Can I use supports from Nissan Sunny or other models?
No, supports from other models, even if they look similar, may have different rigidity, height or mounting points. Installing unsuitable supports will cause the engine to skew and cause rapid failure. Use only parts designed specifically for Nissan Almera Classic with engine Q12.
