Rear suspension spring on a car Nissan Almera Classic performs a critical function, ensuring not only a comfortable ride, but also safe driving. This element is a key link in the system responsible for holding the body at the desired height and dampening vibrations from uneven road surfaces. When a spring fails, the suspension loses its shock-absorbing properties, which leads to sharp impacts on the body and disruption of the geometry of the chassis.
Sedan owners often encounter the problem of the rear axle sagging or a characteristic knocking sound when passing speed bumps. These symptoms indicate that spring life exhausted and the part requires immediate replacement. Ignoring such signs can lead to more serious damage to shock absorbers and stabilizer struts, as well as to an increase in braking distance.
Timely diagnosis and replacement rear springs will return the car to factory handling characteristics and maintain balance between the front and rear axles. In this article we will analyze in detail how to choose the right spare part, what nuances exist during installation and how to avoid typical mistakes made by beginners in suspension repair.
Rear suspension design and the role of springs
Rear suspension Nissan Almera Classic built according to the classic semi-independent beam design, where the spring works in tandem with a hydraulic shock absorber. The main purpose of the spring is to perceive vertical loads and maintain the static height of the body. Without a working spring, the shock absorber will not be able to effectively dampen vibrations, since it will not have a fulcrum for compression and rebound.
It is important to understand that the spring is made of high-strength spring steel, which is subjected to cyclic compression and tension loads. Over time, the metal gets tired, loses its elastic properties and begins to deform irreversibly. That's why spring stiffness decreases over time, which leads to the car sagging even when the trunk is lightly loaded.
Structurally, the spring has a variable pitch of coils, which allows for a soft ride when the car is empty and rigidity when fully loaded. Violation of the integrity of the turns or metal corrosion significantly reduces the service life of the part. The use of springs with reduced stiffness is strictly prohibited for the standard version of Almera Classic, as this will disrupt the kinematics of the beam.
Signs of wear and troubleshooting
It is possible to determine that a spring has become unusable by a number of external and internal signs that become noticeable during vehicle operation. The most obvious symptom is visual sagging of the rear end, where the clearance between the tire and arch becomes uneven or too small.
In addition, it is worth paying attention to the behavior of the car on the road. If you feel that the car has become “rolly”, sways after driving over bumps, or you hear a dull knock when the suspension is compressed, this is a sure sign of problems. Often a knocking sound occurs because the spring has lost its elasticity and the shock absorber begins to operate in rebound mode, hitting the body.
- 🚗 Noticeable subsidence of the rear bumper relative to the wheel arch.
- 🔊 The appearance of extraneous sounds (knocking, creaking) when driving over uneven surfaces.
- ⚖️ Wheel alignment violation due to changes in rear axle clearance.
- 💔 Rapid wear of shock absorbers and rubber bushings.
In some cases, the spring may not visually sag, but have microcracks that lead to sudden destruction. Regular inspection of the suspension on a pit or lift allows you to identify traces of corrosion and chipped paint on the coils, which are harbingers of failure. Do not wait until the part is completely destroyed, as this may damage the brake hoses or wiring.

Review of manufacturers and selection of analogues
When choosing new springs for Nissan Almera Classic The car owner is faced with the question: should he install the original or turn to high-quality analogues? Original spare parts are marked with the manufacturer's code and guarantee full compliance with factory parameters, but their price is often inflated, and availability in warehouses is not always stable.
The market offers many proven brands that produce spare parts that are not inferior to the original in quality and service life. Such manufacturers include Kayaba, Kyowa, Mapco and Febi Bilstein. These companies use the same heat treatment technologies for steel and apply protective coatings to ensure the longevity of the part.
It is important to avoid buying springs from little-known Chinese brands, as they often have low stiffness and quickly lose elasticity. When purchasing, be sure to check the labeling and packaging, as counterfeits are quite common. Spring code must meet the specifications for your model and year of vehicle.
| Manufacturer | Standard size | Approximate resource (km) | Features |
|---|---|---|---|
| Nissan (OEM) | Original | 150 000+ | Perfect compatibility, high price |
| Kayaba | Ultra Super Coil | 120 000+ | Excellent value for money |
| Mapco | 69588 | 100 000+ | Good rigidity, affordable price |
| Febi Bilstein | 32145 | 110 000+ | European quality, strict control |
⚠️ Attention: Do not buy springs “by eye” without checking the car’s VIN code. Different configurations of Almera Classic may have springs with different stiffness depending on engine size and year of manufacture.
Tools and preparation for replacement
The process of replacing rear springs requires a certain set of tools and precautions, since the work involves high spring compression. You will need a jack, car stands, a set of wrenches and sockets, and a special spring puller or vice.
Before starting work, it is necessary to securely fix the car on a flat surface and apply the handbrake. Remove the wheel and unscrew the lower bolt securing the shock absorber to the beam. After this, carefully lower the beam so that the spring weakens, but does not fly out with force.
- 🔧 Socket wrenches and sockets for 14, 17, 19 mm.
- 🏗️ Hydraulic jack and two safety stands.
- 🔨 Hammer and pry bar for dismantling rusty connections.
- 🛡️ Rust remover and WD-40 lubricant.
If you are not experienced with springs, it is highly recommended to use special couplers. This will allow you to safely compress the coils before unscrewing the shock mount, eliminating the risk of injury. Never attempt to remove a spring by simply unscrewing the bolts without first relieving the tension.
☑️ Preparing to replace springs
Step-by-step instructions for replacing a spring
The first step is to remove the wheel and unscrew the lower bolt securing the shock absorber to the rear beam. Use penetrating lubricant if the bolt is stuck and give it time to penetrate the threads. Carefully lower the beam using a jack, controlling the tension of the spring.
Next, you need to remove the spring from its seat. If it is stuck due to corrosion, you can gently tap the coils with a rubber hammer, but do not turn them by force. Install the new springs, making sure that they are seated correctly in the rubber pads and are not displaced relative to the axis.
Raise the beam until the shock absorber is installed and tighten the bottom bolt to the recommended torque. Check the condition of the upper shock absorber mounting in the arch, if necessary, replace the support bearings and rubber bushings. Bolt tightening should be done with the car suspended, when the wheels touch the ground, so as not to twist the rubber elements.
⚠️ Caution: Never tighten the shock absorber bolt to the beam while the vehicle is on the ground unless the spring is already installed or compressed. This may cause the threads to strip or the bolt to break.
What to do if the spring is stuck in the seat?
If the spring does not come out of the groove, do not use excessive force. Use a pry bar to lightly move the beam to the side to make room for the coil. Heating the contact area of the spring with a blowtorch often helps (be careful with the rubber!).
After installing both springs, check the body height on both sides. It should be symmetrical. If the difference is more than 10-15 mm, this may indicate an installation error or a defect in the new part. Carry out a test drive to ensure there are no knocking noises and normal suspension behavior.
Before installing new springs, lubricate the rubber pads with silicone grease. This will prevent them from drying out prematurely and will reduce the risk of squeaks when the suspension is operating.
Installation nuances and common mistakes
One of the most common mistakes is installing a spring without checking the rubber supports. Old cushions often become hard and brittle, and when a new spring is installed, they may simply crumble under the load. Always replace the rubber elements along with the springs to ensure the durability of the repair.
The second common mistake is ignoring the tightening torque of bolts. A tightening that is too weak will cause the bolt to unscrew and the beam will fall, while a tightening that is too strong will cause the threads in the aluminum to break or the shock absorber ear to deform. Use a torque wrench for precise fixation.
It is also important to orient the spring correctly. On some models, the coils have different pitches or end shapes, and installing them the wrong way around can cause the suspension to malfunction and cause the vehicle to sag. Refer to the markings or diagram from the catalog during installation.
- 🔍 Always replace rubber spring cushions along with the springs themselves.
- ⚙️ Use a torque wrench to tighten the bolts.
- 🔄 Check the condition of the shock absorbers before installing new springs.
Replacing springs should be done in pairs on one axle to avoid body distortion and uneven tire wear.
Cost of work and economic feasibility
The cost of replacing rear springs consists of the price of spare parts and service work. On average, a set of two good quality springs will cost from 3,000 to 6,000 rubles, depending on the manufacturer. Replacement work in the service usually costs from 1,500 to 3,000 rubles per axle.
Doing the work yourself allows you to save on labor costs, but requires tools and time. If you do not have experience, it is better to entrust the work to professionals to avoid mistakes that can cost more than the replacement itself. Remember that suspension is a safety issue.
Investment in quality springs pays off in ride comfort and reduced costs for repairs of other suspension components. Saving on cheap analogues often leads to the need for repeated repairs after just a few thousand kilometers. Build quality plays a decisive role in the durability of the chassis.
