Car rear suspension Nissan Almera plays a critical role in ensuring comfort and safety on the road. It is the rear springs that take the brunt of the impact when driving over uneven surfaces, and also keep the body in a horizontal position when loading the trunk. Over time, the elastic elements lose their properties, which leads to sagging of the stern and deterioration in controllability.
Owners of sedans and hatchbacks are often faced with the need to replace these parts. Spring article may vary depending on the year of manufacture and engine type, so it is important to select original spare parts or high-quality analogues. Ignoring suspension problems can lead to accelerated wear of shock absorbers and other chassis components.
Signs of wear and the need for diagnostics
You can understand that the springs have failed by a number of characteristic symptoms that appear even with low mileage. Often the driver notices that the rear of the car has become lower, especially if the car is loaded with passengers or cargo. This is the first sign that the metal is tired and has lost its original rigidity.
In addition to visual subsidence, problems are signaled by changes in the carβs behavior on the road. Excessive rolls appear in turns, and when braking, the stern begins to βdiveβ too much. If you hear characteristic knocks or squeaks from the rear when passing speed bumps, this is a reason to urgently check the suspension.
- π Visual subsidence of the body at the rear relative to the front.
- π The appearance of extraneous sounds (knocking, creaking) in the rear axle.
- π Deterioration of exchange rate stability and increased roll.
- βοΈ Rapid wear of shock absorbers and silent blocks due to uneven load.
Often the problem is masked and appears only when the interior is fully loaded. In such situations suspension sagging becomes critical, the wheel may lose contact with the road or rest against the arch. This is dangerous because it reduces the effectiveness of braking and maneuvering.
β οΈ Attention: Operating a car with sagging springs is strictly prohibited when driving on uneven roads. This can lead to destruction of shock absorbers and failure of the rear brake mechanisms due to geometry violations.
Sometimes the cause of knocking is not the spring itself, but its support or insulator. However, if the metal has cracks or chips, replacement of elements is inevitable. Diagnostics should be carried out on a lift, where a specialist will be able to see hidden defects that are inaccessible during a visual inspection on the ground.
Original spare parts and proven analogues
When choosing new springs for Nissan Almera (G15 or N16), it is important to decide between original parts and high-quality substitutes. Original products from Nissan guarantee compliance with factory specifications, but are much more expensive than analogues. Their catalog numbers often change depending on the market.
There are many manufacturers on the market offering a worthy alternative. Brands like Kayaba, Mapco or Febi have established themselves as reliable suppliers of chassis. However, when purchasing analogues, you must carefully check the consistency of the spring stiffness and height so as not to upset the balance of the suspension.
- β Original (Nissan) - perfect match of geometry and resource, high price.
- π§ Analogues (Kayaba, KYB) - excellent balance of price and quality, often used in services.
- π° Budget brands β suitable for temporary use, but require frequent replacement.
- π« Reconditioned springs - are highly not recommended, since the metal is already fatigued.
It is important to note that the springs for the version with air conditioning or all-wheel drive may differ from the standard equipment. A mistake in choosing will lead to the car driving too hard or, conversely, floating on the road. Catalog number you need to check with the VIN code of your car in the dealer database.

Using the wrong part number may result in the spring simply not fitting into place or having a different compression height. In some cases, it is necessary to replace not only the springs, but also the upper supports to ensure a tight fit.
β οΈ Attention: Never install springs from different modifications on the same axle. A difference in hardness of even 10% can lead to disruption of the ESP system and unstable vehicle behavior.
When purchasing, be sure to inspect the part for manufacturing defects. The paint should be applied evenly, without smudges or chips, as this is the first place where corrosion begins. Factory markings on the coils must be clear and readable, this is a guarantee of the authenticity of the part.
Tools and preparation for replacement
Replacing rear springs is a job that requires some physical strength and specialized tools. Carrying out the procedure yourself is possible in a garage with a pit, but it is better to use a lift to ensure safety. You will need jacks, support stands and a set of wrenches.
Pay special attention to spring compression. Without a special tightening tool, removing it from the shock absorber is extremely dangerous, since the accumulated energy can lead to injury. Use only secure ties designed for suspension work and wear safety glasses.
- π οΈ Set of socket heads and ratchet wrench (main size 12, 14, 17, 19 mm).
- π¨ Hammer and pry bar for pressing levers and racks.
- 𧴠Penetrating lubricant (WD-40 or equivalent) for treating soured bolts.
- π Special spring ties (a must for safety).
Before starting work, be sure to place wheel chocks under the wheels. If you are working in a pit, make sure the vehicle is securely supported. Removing wheels must be done taking into account that the vehicle will be jacked up, so tighten the wheel bolts after placing it on the ground.
βοΈ Preparing to replace springs
Step-by-step replacement instructions
The replacement process begins with removing the wheel and disconnecting the brake hose from the bracket that is attached to the shock absorber. This must be done so that the hose does not stretch when the spring is compressed. Carefully unscrew the fastening bolt and secure the hose to the body using a plastic clamp.
Next, you need to unscrew the lower bolt securing the shock absorber to the steering knuckle or lever. Depending on the model, this may be one or two bolts. Use penetrating lubricant in advance if the bolts are stuck. After unscrewing, carefully lower the shock absorber down.
Now you can move on to compressing the spring. Install the ties on opposite turns and smoothly compress the spring until the tension in the upper mount disappears. This is a critical moment that requires extreme caution.
Unscrew the nut of the upper shock absorber rod and remove the spring together with the shock absorber (or separately, depending on the design). Replace the boot and bumper with new ones if they are worn out. Install the new spring, making sure its lower end is properly seated in the body cup.
Assembly is carried out in reverse order. It is important to remember to tighten the shock absorber mounting bolts to the recommended torque. After installing the spring, make sure that it is not twisted and that the gaps between the coils are even.
What to do if the bottom mounting bolt does not come off?
If the bolt is stuck, do not try to remove it with great force, so as not to break the thread in the lever. Use a quality penetrating compound, heat the bolt with a torch and try to break it off with an impact wrench. As a last resort, you can cut off the bolt with a grinder and replace it with a new one with a sleeve.
β οΈ Attention: When tightening the bolt securing the shock absorber to the lever, it is necessary to keep the rod from turning with a hexagon. Otherwise, you may damage the threads or break the bolt head.
Correct installation of the spring requires the mandatory replacement of the boot and bump stop, since the old parts have already lost their elasticity and can damage the new spring from the inside.
Features of adjustment and wheel alignment
After replacing the springs, the suspension geometry inevitably changes as the body height is restored to the factory level. This means that wheel alignment may be affected. In most cases for Nissan Almera a wheel alignment procedure is required.
Ignoring this step will result in rapid, uneven tire wear and poor handling. The car may begin to βpullβ to the side or wobble when driving in a straight line. Wheel alignment angles must be set with high accuracy.
- π Checking the camber and toe angles is mandatory after replacing the springs.
- π Tire wear on the outside or inside is a sign of geometry violation.
- π Steering wheel movement away from straight-line movement indicates problems with camber.
In some cases, if the springs were selected incorrectly or installed incorrectly, adjustment may not be possible. This indicates that the parts are of incorrect height or rigidity. Service center with modern equipment will be able to accurately determine the cause of deviations.
It is also worth checking the condition of the suspension arms. If the control arm bushings are worn out, replacing the springs alone will not solve the controllability problem. Comprehensive suspension repair always gives better results than spot replacement of individual components.
After replacing the springs and wheel alignment, it is recommended to drive 500-1000 km and re-check the tightness of the suspension bolts, as they may loosen a little during the running-in period.
Frequently asked questions (FAQ)
Is it possible to change springs one at a time?
It is recommended to change springs only in pairs on one axis. If one spring has sagged, the second one is most likely also in a worn state. Installing a new spring on one side will upset the balance of the suspension, which will lead to body distortion and accelerated wear of the shock absorbers.
What is the service life of the rear springs of Nissan Almera?
The average service life of rear springs is from 100,000 to 150,000 kilometers. However, depending on operating conditions (bad roads, overloads), the service life may be reduced to 60,000 km. Focus on the condition of the part, not just the mileage.
Why did the new spring sag immediately after installation?
This may be a sign of a defect or the use of a low-quality analogue. It is also possible that the technology was violated during installation, and the spring did not sit in its normal place. In rare cases, this occurs due to incompatibility with other suspension elements.
Do I need to unload the suspension when replacing?
Yes, when replacing springs, the shock absorber must be in a compressed state to relieve the load. However, to safely remove the spring, it must be tightened with a special tool. Working in weight without the support of a lever is unacceptable, as this may lead to the part falling.
Does replacing springs affect the car's ground clearance?
Yes, replacing worn springs with new ones will restore the factory ground clearance. If you install reinforced springs, the ground clearance will increase, which may require wheel alignment correction and re-flashing of body level sensors (if any).
