Operation of the sedan Nissan Almera new generation (G15 body) leads to changes in suspension characteristics over time. The rear beam, although reliable, experiences enormous loads, especially if the car is used in a taxi or for transporting goods. In this context, springs become a key element determining driving comfort and safety.
Timely diagnosis and replacement rear springs allow you to avoid destruction of shock absorbers, wheel alignment violations and loss of controllability. Many owners ignore body sagging until they hear a characteristic knocking sound or notice uneven tire wear, which ultimately results in much more expensive repairs.
Design features of the Almera G15 rear suspension
In design Nissan Almera The G15 uses a semi-independent rear suspension based on a torsion beam. This solution was not chosen by the engineers by chance: it provides high reliability and ease of maintenance at a reasonable cost. The springs in this scheme perform the function of an elastic element that perceives vertical vibrations from road unevenness.
A special feature of the G15 is that the spring and shock absorber work in tandem, but do not have a common mounting axis in the upper part (the shock absorber is mounted separately). Rear springs here they have progressive stiffness, which allows the car to maintain a smooth ride when empty and rigidity when fully loaded with passengers or luggage.
It is important to understand that the suspension geometry is strictly tied to the spring height. Any deviation from the factory parameters changes the installation angle of the beam, which directly affects controllability. If you notice that the rear of the car has sagged by more than 15-20 mm relative to the norm, you need to check the condition of the elastic elements.
Signs of wear and need for replacement
Determine wear rear springs visually is not always easy, since they are hidden under arches and can be covered with dirt. However, there are indirect signs that should alert the owner. This is a change in ground clearance, the appearance of rolls in corners and knocking in the rear when driving over uneven surfaces.
The most obvious indicator is uneven tire wear. If the spring has lost its properties, the wheel begins to work abnormally, which leads to “wave-like” abrasion of the tread. In addition, shock absorbers begin to work at the limit, which leads to their rapid failure.
Another warning sign is the change in ride height when fully loaded. If, when loading the trunk, the rear axle drops almost to the bump stops, it means that the spring is “tired” and cannot maintain the calculated stiffness. In this case, replacement rear springs is a mandatory procedure.
Review of original components and analogues
When choosing spare parts for Nissan Almera G15 is worth considering two main ways: buying the original or high-quality analogues. Original springs are marked with a code 54020-1HF0A (for the standard version) or have other indices depending on the sales market and year of manufacture. They guarantee full compliance with factory specifications.
However, the market offers many alternatives from brands that specialize in suspension. Manufacturers like KYB, Febest or Mapco often offer products with improved characteristics or a more affordable price. It is important to choose products that have been certified and have positive reviews from other users.
There is also a category of springs with increased rigidity, which are often installed by owners who use the car in taxi mode. Such products allow better load bearing, but can reduce comfort when the car is empty. Deciding to install reinforced springs, it should be taken into account that this will change the behavior of the car on the road.
- Original (Nissan)
- Premium analogue (KYB, Lemforder)
- Budget analogue (Febest, Patron)
- Reinforced springs (for taxis)

⚠️ Attention: Do not buy springs without packaging and labeling. Often, Chinese fakes are sold under the guise of the original, which can burst after just a few thousand kilometers, especially in winter conditions.
The process of diagnostics and preparation for replacement
Before proceeding with dismantling, it is necessary to correctly assess the current state of the suspension. Raise the vehicle on a lift or use secure trestle stands to gain access to the rear beam. Visually inspect the springs for cracks, chipped enamel, or signs of corrosion that could cause the metal to rupture.
Measure the distance from the center of the wheel to the bottom edge of the arch on both sides of the car. The difference should not exceed 10-15 mm. If there is subsidence on one side (obvious), this indicates a loss of elasticity in this particular spring, even if visually it looks intact.
Don't forget to check the status shock absorbers and silent blocks of the beam. It often happens that after replacing the springs, the old shock absorbers begin to knock, because they are not designed for the new load or are simply worn out. Comprehensive suspension repairs are always more economical in the long run.
☑️ Preparing to replace springs
Step-by-step instructions for replacing rear springs
Replacement rear springs on Nissan Almera G15 is a labor-intensive process that requires special tools. You will definitely need spring ties, since dismantling them without compression is impossible and extremely dangerous. It is better to do the work on a pit or a lift.
First you need to unscrew the lower shock absorber mounting bolt that connects it to the beam. This will release the beam, but the spring will still be compressed. Carefully lower the beam, using a jack underneath it to take the load off the spring. Now you can use the ties to compress the spring until it comes out of the seat freely.
After removing the old spring, thoroughly clean the seats on the body and beam from dirt and rust. Install the new spring, making sure it is oriented correctly (direction of coils and stop pads). Unlock the ties slowly and evenly, making sure the spring snaps into place.
Return the beam to its original position and tighten the lower shock absorber bolt to the recommended torque. Don't forget to reinstall the rubber buffers and boots if they were removed. After assembly, be sure to check how the spring sits in the socket and make sure that it is not warped.
What happens if you don't use zip ties?
Attempting to remove a spring without special ties may cause it to fly out with tremendous force, which can result in serious injury or damage to the tool. Metal under load is like a compressed trap spring.
After replacing the springs on one side of the car, it is recommended to replace them on the second side, even if the second side looks normal. This will ensure symmetrical suspension operation and predictable behavior of the car on the road. Different rigidity along the axles can lead to the rear end skidding during sudden maneuvers.
Replacing springs should always be done in pairs on the same axis to maintain suspension symmetry and control safety.
Nuances of operation and expert advice
After installing new rear springs the car may behave differently, especially if parts from a different configuration or with increased rigidity were installed. In the first few hundred kilometers, try to avoid sudden maneuvers and driving through deep potholes at high speed, allowing the suspension to adapt.
Check the condition of the springs regularly, especially after the winter period. The use of deicing agents accelerates metal corrosion, which can lead to the formation of cracks. Applying a special anti-corrosion compound to the springs can extend their service life by several years.
If you frequently transport heavy loads, consider installing auxiliary springs or air bags. They are installed inside the main springs and help maintain ground clearance when fully loaded, unloading the main suspension components and extending their life.
⚠️ Attention: It is strictly forbidden to weld springs if they break or shorten them to lower the body! This violates the design characteristics of the metal, and such a spring can burst at any moment, leading to loss of control.
Correct selection and quality installation rear springs - a guarantee of not only comfort, but also the safety of you and your passengers. Do not skimp on critical suspension elements and entrust the work to professionals if you are not confident in your abilities. A high-quality suspension is a guarantee that your Nissan Almera G15 will serve you long and reliably.
Before starting work, be sure to go to the service center and find out the exact spring part number under the VIN code of your car, as there may be differences depending on the year of manufacture and the market.
Frequently asked questions (FAQ)
Is it possible to replace just one spring?
Technically this is possible, but it is highly not recommended. Different spring stiffnesses along the axles will lead to imbalance in the suspension, uneven tire wear and poor handling. Always replace springs in pairs.
How to distinguish a taxi spring from a regular one?
Typically, reinforced springs have a higher coil section and are marked with a special color or sticker. They can also have a greater free height. Check with the seller about the purpose of the part before purchasing.
Do I need to do a wheel alignment after replacing the springs?
Yes, since replacing the springs changes the suspension geometry and ground clearance, the wheel alignment angles may be off. To ensure stable straight-line movement and uniform wear of rubber, wheel alignment is necessary.
What is the service life of the rear springs on the Almere G15?
On average, original springs last 100-150 thousand kilometers. However, the service life depends on operating conditions: the quality of roads, frequency of cargo transportation and climatic conditions can significantly shorten this period.
⚠️ Attention: Never attempt to replace a spring without the use of professional ties and safety ropes, as the risk of serious injury if the spring comes off is extremely high!
