Introduction
Sedan rear suspension Nissan Almera The G15 generation experiences enormous loads, especially on Russian roads. Over time, the springs lose their elasticity, which leads to sagging of the body and a change in the camber angle of the wheels. Ignoring this problem can cause rapid wear of the shock absorbers and unstable behavior of the car on the track.
Replacement process rear springs requires not only the availability of tools, but also an understanding of the design features of the suspension. Unlike the front struts, the rear axle Nissan Almera has its own nuances of dismantling and installation that must be taken into account for safe operation.
Signs of wear and diagnostics
How to understand that the springs have exhausted their service life? The most obvious sign is the visual sagging of the rear of the car. If, when the trunk is fully loaded, the body touches the arches, and when the car is empty, the rear part looks “squat,” this is a sure sign of problems with elastic elements.
In addition, pay attention to the nature of the knocks when driving over uneven surfaces. If the shock absorbers are working properly, but the knocking noise persists, the problem lies in support cups or the springs themselves. Metal breaks, corrosion and deformation of coils are visible to the naked eye when the car is lifted on a lift or jack.
Sometimes drivers notice uneven tire wear. This happens because Nissan Almera G15 loses correct wheel alignment angles when the body sag. Timely replacement rear springs will return the car to factory suspension geometry parameters.
Selection of spare parts: Original or analogues?
The auto parts market offers a huge selection of springs for Nissan Almera. Original parts, as a rule, are marked according to the VIN code and provide maximum service life. However, their cost is often two to three times higher than similar products from third-party manufacturers.
Among the popular manufacturers of spare parts are: Kyb, Mapco and TRW. These brands produce parts that are equal in quality to the original, and sometimes even surpass it due to improved steel alloys. When choosing, it is important to pay attention to the color marking, which indicates the spring stiffness.
It is not recommended to buy springs secondhand or from disassembly, since their residual life is impossible to predict. Installed used items They can sag after just a couple of thousand kilometers, nullifying all repair efforts.

Necessary tools and preparation
To carry out the work, you will need a standard set of plumbing tools, but taking into account the specifics of the suspension. Availability required jack and support stands (goats), since working under the machine on one jack is strictly prohibited. You also cannot do without a spring remover if you plan to completely disassemble the rack, although in this case, most often you only need to lower the lever.
You will need 14, 17, 19 and 21 millimeter socket and socket wrenches. A penetrating lubricant is indispensable for treating rusty joints. WD-40 or similar composition. Don't forget to prepare mount and a hammer, since the seats often stick to the body.
Before starting work, make sure that the car is on a level surface. Secure the front wheels with wheel chocks. Loosen the rear wheel bolts before you raise the car.
☑️ Preparation for replacement
Step-by-step replacement instructions
The process begins by lifting the car and removing the rear wheels. Clean the shock absorber mounting area from dirt and rust to avoid the bolts jamming when unscrewing. Unscrew the lower bolt securing the shock absorber to suspension arm. This will require considerable effort, especially if the bolt has not been serviced for a long time.
After unscrewing the bottom bolt, carefully lower the shock absorber down. Be careful not to damage the brake hose and ABS wiring, if present. Now you can carefully pull the spring out of its seat. Often the spring sits tightly, and to remove it you will need to carefully pry it off pry bar.
Installing a new spring is carried out in the reverse order. Carefully check the alignment of the upper and lower ends of the spring with the seat cups. The spring should fit tightly, without distortion. After installation shock absorber tighten the bottom bolt to the required torque, which is usually about 120 Nm.
If the cable is too short, it may prevent the lever from lowering to the down position. In this case, you will need to loosen the cable tension on the regulator inside the cabin or under the bottom.
The nuances of installing a shock absorber
When installing a shock absorber, a problem often arises with the alignment of the bolt holes. Do not attempt to tighten the bolt with a pry bar as this may damage the threads. It's best to use a mandrel or gently jack the arm to line up the holes.
⚠️ Attention: Never unscrew the upper nut of the shock absorber rod while hanging, as this may damage the rod or shock absorber body. Always secure the stem with a special key or holder.
Before starting work, take a photograph of the location of the spring and its coils. This will help you install the new part correctly if you are unsure of the orientation of the ends.
Specifics of Nissan Almera G15 springs
Rear suspension feature Nissan Almera consists of using springs with a variable pitch of turns. This ensures a smooth ride when the car is empty and rigidity when fully loaded. When replacing, it is extremely important to select springs with similar characteristics, otherwise the suspension will become either too soft or too hard.
Springs are installed at the factory and are often color coded. For example, yellow could mean standard hardness, while green could mean enhanced hardness. When purchasing replacements analogues Be sure to check this parameter with the seller. A mismatch in stiffness will lead to rapid failure of new shock absorbers.
It is also worth noting that the rear springs are Nissan Almera G15 have special protection against corrosion, which can deteriorate over time. When installing new elements, it is recommended to check the condition of the protective covers and, if necessary, replace them to extend their service life springs.
| Parameter | Meaning |
|---|---|
| Suspension type | Semi-independent beam |
| Spring material | Carbon steel |
| Color coding | Yellow (standard) |
| Recommended tightening torque | 120 Nm (bottom bolt) |
| Service life | 80-120 thousand km |
⚠️ Attention: If you change only one spring, this may lead to body distortion and uneven tire wear. Springs should be replaced strictly in pairs on the same axis.
Common mistakes and how to avoid them
One of the most common mistakes is trying to tighten the lower shock absorber bolt without preloading the suspension. This creates preload, which leads to rapid destruction of silent blocks and support cups. Always lower the vehicle onto its wheels before final tightening of all fasteners.
Another mistake is using lubricant on threaded connections unnecessarily. Lubricant can cause the bolt to loosen due to vibration. If the bolts do not budge, use a penetrating lubricant, but during assembly it is better to use a thread locker, especially for bolts shock absorber.
Don't forget to check the status fenders and anthers. If they are torn or have lost elasticity, they must be replaced along with the springs. Ignoring this element will result in the shock absorber rod hitting the body, which will cause its rapid failure.
The final tightening of the suspension bolts should only be done after the vehicle is on its wheels and the suspension is under load.
FAQ: Frequently asked questions
Can springs from other Nissan models be installed?
No, install springs from other models, for example, from Nissan Tiida or Sentra, not recommended. Suspension geometry and spring rates may vary, leading to handling and comfort issues.
How long does it take to replace springs?
If you have experience and the right tools, replacing springs on one axis takes about 1.5–2 hours. If you are doing this for the first time, spend more time learning the nuances and dealing with stuck bolts.
Do I need to do a wheel alignment after replacement?
In suspension Nissan Almera G15 the rear beam does not have camber and toe adjustments. However, if replacing the springs has led to a change in ground clearance, it is recommended to check the wheel alignment angles to prevent uneven tire wear.
What to do if the spring is stuck in the cup?
Never try to knock out the spring coils with a hammer. Use a pry bar to gently pry, or lightly tap the cup itself with a hammer to knock off any rust. Sometimes heating the cup with a hair dryer to expand the metal helps.
Is it possible to install reinforced springs?
Reinforced springs can be installed if you often transport heavy loads. However, this will increase the stiffness of the suspension and reduce comfort when the car is empty. Make sure your shock absorbers are designed to handle stiffer springs.
