Many owners Nissan Almera Classic encounter a problem when the hood no longer holds in the open position. This occurs due to failure of standard springs or gas stops. This situation creates serious discomfort when servicing the car under the hood, since you have to constantly hold the cover with your hand or look for a foreign stick to fix it.
The hood lift system in this model often causes complaints even at the stage of purchasing a new car, but the problem gets worse with mileage. Gas struts are a critical hood suspension element for safety and ease of use. If you notice that the mechanism has stopped working correctly, do not delay repairs for a long time to avoid the risk of the hood falling on your head.
Why do standard Nissan Almera Classic stops fail?
Factory shock absorbers on model Nissan Almera Classic often have a resource that does not exceed 3-4 years of active operation. The main reason for premature failure is poor-quality rod sealing and the use of cheap gas mixtures inside the cylinder. At low temperatures, the viscosity of the oil changes, which leads to loss of seal tightness.
In addition, external factors influence wear: dust, dirt and road reagents that get on the rod. Scratches on the rod the rubber seal is instantly destroyed and gas begins to escape from the chamber. Owners often ignore the first signs of sagging until the hood completely stops holding the load.
Another factor is improper compression force. Sometimes the manufacturer sets the stops with insufficient force for a heavy hood. Insufficient pressure in the gas chamber does not allow keeping the lid in the upper position, especially in winter.
Criteria for selecting high-quality analogues
When selecting a replacement, it is important to pay attention to the compression force, which is measured in Newtons (N). For Nissan Almera Classic The optimal range is considered to be from 400 to 500 N. Stops that are too weak will not lift the hood, and stops that are too strong can damage the hinges when opening or create a risk of injury if closed accidentally.
There are many manufacturers offering products to the secondary market. Some brands have proven themselves to be reliable, while others produce low quality products. When choosing, pay attention to the presence of a warranty card and quality certificates.
- 🔍 Check the labeling on the body of the stop - it should be clear and not wear off over time.
- 🛡️ Check availability protective cover on the rod, which prevents dirt from entering.
- 📏 Check the length in compressed and decompressed state with original parameters.
Particular attention should be paid to brands specializing in gas-filled products. Well-known manufacturers such as Stabilus or JS Asakashi, usually offer a longer lifespan, but may cost more.

Preparing for DIY replacement
Replacing the stops is a procedure that can be performed independently in a garage or even on the street. The main requirement is the presence of free space and the absence of drafts that could interfere with work. You don't need sophisticated equipment, just a basic set of tools.
Before starting work, it is necessary to securely fix the hood in the open position. Use the stop that you remove last, or a special clamp. Security When working with the hood, it comes first, as sudden closing can lead to serious hand injuries.
You will need the following tools and materials to carry out the work:
- 🔧 Thin drill or a screwdriver for removing the ball joint retainers.
- 🧤 Gloves to protect hands from dirt and sharp edges.
- 🧴 Lubrication such as WD-40 or lithol for treating fastening points.
It is recommended to replace two stops at once, even if the second one is still holding the hood. This will ensure uniform load distribution and synchronous operation of the mechanism in the future.
☑️ Preparation for replacement
Step-by-step replacement instructions
The dismantling process begins with disconnecting the ball ends from the brackets. In most cases, plastic clips are used, which need to be carefully pryed off with a screwdriver. Do not use excessive force to avoid breaking the fragile plastic of the mount.
After removing the old element, it is necessary to clean the seats from rust and dirt. Apply lubricant to the brackets so that the new stops will attach easily. Clean contacts guarantees the durability of the fastening and the absence of backlash.
Installing a new stop occurs in the reverse order. Pay attention to the installation direction: usually the ball end should face down, but this depends on the specific batch and design. Press the latch until it clicks to make sure the connection is secure.
What to do if the latch is broken?
If the plastic retainer is cracked, do not attempt to glue it back together. Use thin wire or a tie for temporary fixation, but it is better to immediately replace the fastener with a new one or use a universal set of fasteners.
After installing both stops, check their operation. The hood should rise and fall smoothly, holding at any point with a light touch. If the hood drops too quickly, the stops may be too weak.
Typical errors during operation and repair
One of the most common mistakes is incorrect installation of stops. Many car owners confuse the upper and lower fastenings, which leads to the fact that the hood does not open at all or gets stuck in the middle of the move. Correct orientation rod and cylinder are critical to the operation of the mechanism.
It is also unacceptable to use stops from other car models without checking their characteristics. Even visually identical products may have a different compression force or length. This may lead to deformation of the hood hinges or the inability to open it.
Ignoring periodic lubrication of ball joints will also shorten the life of the mechanism. Dust and dirt act as an abrasive, quickly erasing friction surfaces. Regular maintenance extends the life not only of the stops, but also of the hinges themselves.
Before installing new stops, check to see if the hood is misaligned relative to the body. If the hood is distorted, the stops will work under increased load and quickly fail.
Comparison table of popular stop models
For clarity, let’s compare the characteristics of the most popular analogues available on the Russian market. This will help you make an informed choice when purchasing spare parts for Nissan Almera Classic.
| Brand | Force (Newton) | Compressed length (mm) | Service life (approx.) |
|---|---|---|---|
| Stabilus (Original) | 450 | 335 | 5-7 years |
| JS Asakashi | 430 | 335 | 3-5 years |
| Chinese analogues | 300-400 | 330-340 | 1-2 years |
| ProSport | 480 | 338 | 4-6 years |
⚠️ Attention: When buying cheap Chinese analogues, you often encounter a discrepancy between the declared effort and the real one. Such a stop may not raise the hood in cold weather or, conversely, tilt it back too sharply.
⚠️ Attention: Never attempt to disassemble or charge the gas strut yourself.. This is a sealed, high-pressure system that, if damaged, could result in an explosion and serious injury to the eyes or skin.
Troubleshooting hood hinge problems
Sometimes the problem is not the stops themselves, but the worn hinges. If the hinges have significant play, the hood will sag, and even new stops will not be able to compensate for this defect. In this case, adjustment or replacement of the hinges themselves is required.
The hood is adjusted by loosening the hinge bolts and moving them. This allows you to even out the gaps and change the angle of inclination. Fine tuning reduces the load on gas shock absorbers and extends their service life.
In advanced cases, when the metal of the hinges is deformed or rotten, the only solution is to completely replace them. This is a more labor-intensive procedure that requires dismantling the engine compartment trim, but it is necessary for the safe operation of the vehicle.
Replacing hood stops is not just a cosmetic repair, but a safety issue. Reliable shock absorbers prevent accidental closure of the hood during engine maintenance.
How to check the hood stop without tools?
Lift the hood with your hands and release. If it lowers on its own, the stops are worn. You can also try rocking the hood up and down: if you feel play or “failure” in a certain position, it means the gas has left the chamber.
Can springs be used instead of gas stops?
Theoretically possible, but not recommended for Nissan Almera Classic. The springs create a sudden load and can deform the hood. In addition, they operate less smoothly and often create strange sounds when moving.
How long does it take to replace stops?
If you have the tools and minimal experience, the procedure takes from 15 to 30 minutes. The main thing is to take your time when dismantling the plastic fasteners, so as not to damage the fasteners.
What to do if the stop does not hold the hood after replacement?
First, check that the installation is correct: you may have mixed up the left and right stops or put the clamp on incorrectly. If the installation is correct, you may have received a defective copy - contact the seller for a replacement.
