Operation Nissan Almera new generation (G15) in Russian road conditions often leads to accelerated wear of the suspension, especially in the rear. You may notice that the car has become lower at the rear, the ground clearance has changed, or an unpleasant knocking sound has appeared when driving over bumps. These symptoms indicate that rear springs have lost their elastic properties and require immediate replacement to restore comfort and safety of control.
Many owners Nissan Almera G15s are faced with the fact that factory parts have a life that does not always meet expectations, especially when using the machine for transporting goods or operating in rural areas. Rear suspension sag not only worsens the appearance, but also changes the wheel alignment geometry, which leads to uneven tire wear. In this article we will look in detail at how to carry out your own replacing rear springswithout resorting to expensive services.
Diagnosis and causes of sagging rear suspension
Before you start purchasing spare parts and dismantling components, you need to make sure that the problem is elastic elements pendants. Owners often confuse sagging with wear on shock absorbers, although these parts work in pairs and influence each other. If Nissan Almera The G15 looks "squat" from the rear, check the height of the bead over the wheel on a flat surface.
The main reasons for spring failure are related to cyclic loads and corrosion. Winter use, the use of reagents and constant driving on bad roads lead to the metal becoming tired. Microcracks in coils, the springs eventually turn into complete destruction, which can happen suddenly even when moving in a straight line. It's also worth noting that the original springs on this model are sometimes undersized for harsh conditions.
- 🔍 Visual inspection of the coils for rust and paint chips.
- 📏 Rear body height measurement and comparison with factory standards.
- 🚗 Test drive: no suspension breakdowns or extraneous sounds.
If you notice that the spring is broken or has an obvious bend, the operation of the vehicle becomes dangerous. Loss of elasticity leads to the fact that the shock absorber begins to work in abnormal mode, quickly collapsing itself and affecting the suspension arms. You should not delay repairs, as the cost of replacing one suspension unit may be higher than the cost of the spring.
⚠️ Attention: Operating a car with a damaged spring coil is strictly prohibited, as sharp edges can damage brake hoses or wiring.
Selection of spare parts: Original or analogues?
Spare parts market for Nissan Almera The G15 offers many options, from dealer originals to budget counterparts. The choice depends on your budget and driving style. Original spring (article 54025-1HC0A) provides factory rigidity, but many owners complain about its insufficient durability. Often original parts become unusable after 80-100 thousand kilometers.
Alternative manufacturers offer reinforced options that can last longer. Brands like KYB, KYB Excel-G or Febi often have improved anti-corrosion treatment and higher rigidity. Reinforced springs Great for those who frequently carry passengers or luggage, but they can make the ride rougher when the car is empty. It is important to choose a part that suits your operating style.
- 💰 Original: Perfect match, but often more expensive and less durable.
- 🛠 Analogs (KYB, Lemforder): Good value for money, often improved geometry.
- 🚛 Reinforced options (Mando, GABRIEL): For severe conditions, but higher suspension stiffness.
When purchasing, be sure to check for a protective coating. A quality spring should be covered epoxy enamel or a polymer that prevents corrosion. If you see obvious casting defects or an uneven surface, it is better to refuse the purchase. It is also worth paying attention to kits that include boots and compression buffers, since replacing them when dismantling the springs is mandatory to preserve the life of the suspension.

Necessary tools and workplace preparation
To carry out work on replacing the rear springs with Nissan Almera G15 you will need a standard set of automotive tools. Without special equipment and jack coping with the task will be extremely difficult and unsafe. Make sure you have sturdy stands under the body, as relying solely on the jack's hydraulics is not acceptable when working under the vehicle.
The key is to have a spring puller as they are under significant tension. Attempting to remove the upper support bearing without compressing the spring may result in personal injury or parts failure. Special puller allows you to safely compress the coil and release the fastening unit. Also, be sure to prepare a penetrating lubricant (WD-40 or equivalent) to treat threaded connections that often stick.
- 🔧 Set of socket heads (12, 14, 17, 19 mm) and ratchet.
- 🔨 Hammer and pry bar for breaking stuck bolts.
- 🏗 Spring remover (required!) and jack with stands.
It is best to work on a level surface or in a viewing hole. Raise the rear of the car, place it on stands and remove the wheels. This will provide access to the upper shock absorber mounts, which are located in the luggage compartment. Cleaning the fastening zones from dirt and rust before starting work will greatly simplify the dismantling process.
☑️ Preparing to replace springs
Step-by-step instructions for dismantling and installation
The replacement process begins by accessing the top of the shock absorber. Open the trunk and remove the plastic trim to gain access to the stem nut. Unscrew the top nut, holding the rod from turning with a 6 mm wrench. Upper support is now free, but the spring is still compressed under the weight of the machine.
Move to the bottom of the pendant. Loosen the bolt securing the lower arm to the shock absorber. Use penetrating lubricant, if the connection fails. Disconnect the ABS sensor if it is attached to the shock absorber to avoid damaging the wiring during removal. Lower the jack under the lever so that the spring is slightly relieved, and carefully remove the shock absorber along with the spring.
Place a spring remover on a workbench and compress it until the tension on the supports disappears. After this, you can remove the upper support and separate the shock absorber from the spring. Inspect the Buffer compression and boot - if they are worn out, replace them with new ones. Install the new spring in the correct orientation (usually the outermost coil should be turned to the side). Reassemble the assembly in the reverse order, remembering to tighten all bolts to the required torque.
⚠️ Attention: When using a spring puller, make sure that the jaws are symmetrically positioned to avoid distortion and sudden breakage of the tool.
How to determine the correct spring orientation?
The rear spring of the Nissan Almera G15 usually has a marking or color mark. The lower coil often has a smaller pitch, and it is this that should be installed in the lower cup. If the spring is upside down, it may jump out when the suspension is operating, causing an accident.
After installing the spring on the car, before tightening the bolts completely, you need to make sure that the spring is seated in its seats. Raise the arm with a jack, simulating the weight of the car, and tighten the lower shock absorber bolt. Bolt tightening under load it will prevent their rapid unscrewing and destruction of silent blocks. Tighten the upper stem nut to the torque recommended by the manufacturer.
Before tightening the lower shock absorber mounting bolt, make sure that the splined portion of the shaft does not have any burrs that could interfere with proper installation and cause play.
Torque table and specifications
Maintaining the correct tightening torques is the key to long service life of the suspension. Under-tightened bolts can lead to destruction of elements, and over-twisted ones can lead to thread failure or deformation of parts. Below is a table with recommended values for Nissan Almera G15.
| Fastening element | Tightening torque (Nm) | Note |
|---|---|---|
| Shock absorber rod nut | 45 - 50 | Hold the stem with a hexagon |
| Bottom mounting bolt | 130 - 140 | Tighten under load |
| Bracket bolt | 80 - 90 | Mounting to body |
| Lever axle nut | 105 - 115 | Check after mileage |
The use of a torque wrench during assembly is a prerequisite for professional repairs. Conventional ratchets do not provide precise force control. Tightening control It is recommended to carry out 500-1000 km after replacement, since new suspension elements may “settle” a little and weaken the connection.
Correct tightening of the shock absorber mounting bolts under load (when the wheel is lowered to the ground or the lever is suspended) is critical to the life of the silent blocks.
After replacement: wheel alignment and test drive
After replacing the springs, the suspension geometry may change as the body height returns to factory values. This inevitably affects wheel alignment angles. Wheel alignment This must be done, otherwise you will quickly “eat up” the rubber. On Nissan Almera G15 rear wheel camber adjustment is often limited, but checking the caster and toe angles is mandatory.
The first kilometers after the replacement should be spent in a quiet mode. Avoid sudden braking, deep potholes and high speeds. Checking work suspension on uneven surfaces will help identify possible errors during assembly, such as misaligned springs or poorly tightened bolts. If you hear knocking or squeaking noises, return to diagnostics immediately.
- 🛣 Drive 500 km and check the tightness of all bolts.
- 📐 Make a wheel alignment at a specialized stand.
- 👂 Listen to the sounds when driving over uneven surfaces.
If you choose reinforced springs, be prepared for the fact that ride comfort may drop slightly on poor asphalt. However, the stability of the car when turning and transporting cargo will increase significantly. Carefully monitor the condition of the suspension in the future, as replacing one spring often reveals wear on other elements.
What should I do if after replacement the car becomes stiffer?
This is a normal reaction when installing new springs, especially if they are reinforced. After 1000-2000 km, the suspension will “get used to” a little, and the stiffness will become more comfortable. If vibrations are excessive, check that the compression buffers are installed correctly.
Frequent mistakes and expert advice
One of the most common mistakes is replacing only one spring. Even if the second one looks intact, it has already exhausted its service life and has similar wear and tear. Replacement by pair guarantees equal rigidity along the axles and safe behavior of the car on the road. The difference in stiffness can lead to instability when braking.
Ignoring the condition of support bearings and buffers also leads to rapid failure of new springs. If the support does not rotate or the buffer is stiff, the new spring will work under extreme conditions. Complex replacement The entire set (spring, boot, buffer, support) saves time and money in the long run.
⚠️ Caution: Do not attempt to use a sledgehammer to remove jammed shock absorber bolts, as this may damage the body or deform the arms.
Remember that Nissan Almera The G15 has a rear suspension design where the spring and shock absorber are separate but operate as a single unit. Any error in installation may result in loss of control. If you are not confident in your abilities, it is better to entrust the work to professionals, but knowledge of the process will help you control the quality of the repair.
Questions and answers (FAQ)
How long does it take to replace rear springs?
With experience and the right tools, replacing springs on both sides takes 2 to 3 hours. If this is your first time doing this, allow 4-5 hours for the work, as stuck bolts may require additional processing time.
Do I need to do a wheel alignment after replacing the springs?
Yes, definitely. Replacing springs changes the body height and wheel alignment angles. Without wheel alignment correction, you risk quickly wearing out the tires and deteriorating the car's handling.
Is it possible to install reinforced springs on the Nissan Almera G15?
Yes, you can. Heavy-duty springs (such as from Koni or specialist tuning brands) increase load capacity and stability, but stiffen the suspension. Make sure they are compatible with your body type.
How often should rear springs be replaced?
The average life of springs is 100,000 - 150,000 km, but in bad road conditions this period can be reduced to 60,000 km. Check their condition regularly at every oil change.
What happens if you don't replace a broken spring?
Driving with a broken spring is dangerous: the sharp edges can cut the brake hose, causing brake failure. The suspension geometry is also disrupted, which can lead to loss of control.
