⚠️ Attention: Replacing rear shock absorbers with Nissan Almera N16 requires the use of a torque wrench, since tightening the rod nut without fixing the rotation will lead to rapid destruction of the support bearing and the appearance of squeaks.
Suspension repair is not just a replacement of worn parts, but an opportunity to return the car to factory handling and comfort characteristics. On Nissan Almera N16 The rear suspension is made using a semi-independent beam design, where shock absorbers play a critical role in damping vibrations. Many owners put off visiting a service station, attributing the knocking noise to the age of the road, but ignoring the problem leads to accelerated wear of the springs and body.
Timely replacement rear pillars prevents loss of wheel traction on uneven surfaces, which directly affects safety. If you hear characteristic sounds when passing speed bumps or notice that the car has become worse in maintaining its trajectory in turns, suspension diagnostics should be carried out immediately.
Diagnostics and signs of shock absorber wear
Determine the need to replace the rear struts with Nissan Almera N16 This is possible not only by sounds, but also by the behavior of the car in motion. The most obvious signal is the appearance of a knocking sound, which intensifies when driving over uneven surfaces. This sound occurs because shock absorbing insert lost its properties and stopped dampening the vibrations of the spring, which is why metal hits metal.
⚠️ Attention: If during a visual inspection you find oil leaks on the shock absorber body, this is a sign of seal depressurization. Driving with such parts is dangerous, as the damping efficiency drops significantly.
The second important sign is increased body roll when cornering or a “rolling” feeling after pressing the brake. The car may behave erratically, especially at speeds above 60 km/h. It is also worth paying attention to uneven tire wear. If the tread wears off on one side of the wheel faster than the other, this may indicate a bad tire. hydraulic damper.
- 🔊 The appearance of dull knocks or squeaks when driving over uneven surfaces.
- 🎢 Excessive “rocking” of the body after pressing the brake or when turning.
- 💧 Visible traces of oil on the shock absorber body below the boot.
- 🚗 Increased braking distance and instability of control at high speed.
Selection of quality spare parts: brands and articles
When choosing spare parts for Nissan Almera N16 It is important to understand the difference between original parts and high-quality analogues. Official original from Nissan is usually expensive, but guarantees exact compliance with factory specifications. However, there are many proven manufacturers on the market offering products that are not inferior to, and sometimes even superior to, the original in terms of service life.
For rear struts for this model, German brands have proven themselves to be excellent, such as Kayaba (Excel-G or New SR series) and Sachs. These manufacturers use quality materials and technology to ensure long service life even under harsh operating conditions. Japanese analogues from Monroe are also a worthy choice for those who value comfort.
- 🇯🇵 Kayaba - market leader, ideal balance of price and quality (Excel-G for comfort, New SR for sport).
- 🇩🇪 Sachs - a premium German version that provides a high smooth ride.
- 🇫🇷 Monroe — reliable shock absorbers with good adaptation to Russian roads.
- 🇨🇳 ASVA - a budget option, but with an unpredictable resource, suitable only for temporary driving.
It is important to consider that not only the shock absorber itself is often replaced on the rear axle, but also the support cups, boots and compression buffers. Components from the manufacturer Febi or SWAG will help extend the life of new racks. Do not skimp on these little things, as replacing them requires repeated removal of the unit, which will increase the cost of work in the future.
Necessary tools and preparation for work
To replace the rear struts yourself, you will need a standard set of tools, but there are nuances that will simplify the process. You will need 14mm, 17mm, 19mm and 21mm spanners and a torque wrench for final tightening. It is necessary to have a jack and reliable stands, since working under a car without insurance is prohibited by safety regulations.
⚠️ Attention: Before starting work, be sure to secure the car on the handbrake and place wheel chocks under the front wheels. The rear beam has significant weight, and if it is not secured correctly, it can fall off the jack.
Pay special attention to the wrench for fixing the shock absorber rod. On Nissan Almera N16 The rod has a 6mm or 7mm hex key, but sometimes it rotates and a special hex wrench with a long lever is required. If you do not have such a tool, you can use a vice or a gas wrench, but this must be done very carefully so as not to damage the threads of the rod.
☑️ Preparing to replace the rear struts
It is also recommended to prepare a penetrating lubricant (such as WD-40 or Liqui Moly), since the fastening nuts often stick to the body. Treat them in advance to avoid thread stripping or bolt breakage when unscrewing. If you plan to change the springs, stock up on spring ties - without them, replacement is impossible.
Step-by-step instructions for removal and installation
The replacement process begins with lifting the car and removing the wheel. After this, you need to find the lower shock absorber mount, which is a bolt that goes through the beam eye and the bottom of the strut. Unscrew the nut of this bolt and knock it out using a pry bar or hammer.
Next you need to go to the trunk of the car. Remove the plastic trunk trim to gain access to the top of the shock absorber. There you will see two nuts securing the upper support to the body. Unscrew them with a 14 or 17 mm wrench. It is important to hold the shock absorber rod from below so that it does not rotate along with the nut.

- Sachs (Germany)
- Monroe (France)
- Original Nissan
After unscrewing the top nuts, carefully remove the post from the beam eye. If it does not come out, you may need to jack up the beam slightly to reduce the spring tension, but this must be done very carefully so as not to damage the body or brake cables.
Installing the new part is done in the reverse order. First, insert the rod into the body hole and tighten the top nuts, but not completely. Then lower the beam with a jack so that the rack eye is aligned with the hole in the body, and insert the lower bolt. The fasteners need to be tightened only when the car is standing on its wheels to avoid distortion of the rubber-metal bushings.
Important nuances of tightening and adjustment
The torque of the shock absorber rod nut is critical. If you tighten it too much without locking the rotation, the stem bushing may break. If you tighten it loosely, a knock will appear. The ideal option is to use a torque wrench and secure the rod with a hexagon. Tightening torque for Nissan Almera N16 Usually it is about 30-40 Nm, but it is better to clarify this value in the manual.
⚠️ Attention: Never tighten the lower nut securing the shock absorber to the beam until the vehicle is lowered to the ground. Rubber bushings must operate under load, otherwise they will quickly twist and fail.
It is also worth paying attention to the condition of the anthers and compression buffers. If they are torn or have lost elasticity, they must be replaced. Ignoring this step will result in dirt getting on the shock absorber rod, which will cause rapid oil seal wear and oil leakage.
- 🔧 Use a torque wrench to accurately tighten all fasteners.
- 🛡️ Be sure to replace the anthers and compression buffers along with the struts.
- ⚙️ Check the condition of the lower arm bushings when dismantling the strut.
- 🚫 Do not tighten the lower fastening all the way until the car is on wheels.
Comparison of shock absorber characteristics
To understand which shock absorber is best suited for your conditions, it is worth considering their technical features in the table. Differences can be not only in the brand, but also in the damping stiffness, which affects the behavior of the car on the road.
| Brand/Series | Hardness | Comfort | Resource | Features |
|---|---|---|---|---|
| Nissan (Original) | Average | High | Medium | Ideal balance for normal use |
| Kayaba Excel-G | Average | Medium | High | Classic gas shock absorber, reliable |
| Kayaba New SR | Increased | Below average | Very tall | For lovers of sporty driving and bad roads |
| Sachs Super Touring | Average | Very tall | High | Soft setting, maximum comfort |
| Monroe Reflex | Average | High | Medium | Good damping at high speed |
The choice depends on how you use the car. If you often drive around the city and like softness, then Sachs or the original will be the best choice. Better suited for bad roads and aggressive driving Kayaba New SR or Monroe. Remember that too hard a suspension can lead to destruction of body elements on bumps, and too soft a suspension can lead to rolls.
Why are shock absorbers replaced in pairs?
It is recommended to change shock absorbers on one axle in pairs, since the wear of the second strut is already close to critical. Different stiffness of the struts will lead to uneven weight distribution and poor handling, especially during emergency braking.
Common mistakes during repairs
Many car owners make mistakes when trying to save time or money. The most common mistake is replacing only one rack. This leads to an imbalance in the suspension, and the car begins to behave unpredictably. Always replace shock absorbers on one axle as a set.
Another mistake is using old springs with new shock absorbers. Springs sag over time and lose their elasticity. Installing a new strut on an old spring will not give the expected comfort effect and may cause the shock absorber to work at the limit of its capabilities, failing faster.
Before installing new struts, be sure to check the condition of the silent blocks of the rear beam. If they are torn, even new shock absorbers will not provide adequate smoothness and silence in the cabin.
Also, do not ignore checking other suspension elements. Often, a knocking noise that seems to be coming from the shock absorber is actually coming from worn out arms or the anti-roll bar. Carry out a complete diagnosis so as not to change parts in vain.
A high-quality replacement of the rear struts is impossible without checking the adjacent suspension elements and using the correct tool to tighten the fasteners.
Is it necessary to do a wheel alignment after replacing the rear struts?
On Nissan Almera N16 The rear suspension is a beam suspension, and the rear wheel alignment angles are not adjustable. Therefore, after replacing the rear shock absorbers, it is not necessary to do an alignment if the levers or beam were not affected. However, if you also changed the springs, or the beam was distorted, checking the angles will not be superfluous.
Is it possible to install gas shock absorbers instead of oil ones?
Yes, it is possible and necessary. Factory racks on Nissan Almera N16 They are often oil-filled or low-pressure gas-filled. Modern gas shock absorbers (for example, Kayaba Excel-G) provide better stability and durability, although they may be slightly stiffer. This is standard practice for suspension upgrades.
How to distinguish an original stand from a fake?
Original spare parts have clear markings, high-quality paint without smudges and smooth threads. Counterfeits often have crooked nameplates, cheap packaging and are lighter in weight. Also original from Nissan or Kayaba (as an OEM supplier) must have a protective case and a quality compression buffer included. Original shock absorbers always have a serial number, which can be verified by an authorized dealer.
How long does it take to replace rear struts?
An experienced technician will spend about 1.5–2 hours replacing a pair of rear struts. For a beginner, this process can take 3-4 hours, especially if the nuts are stuck and require prolonged treatment with penetrating lubricant. Having the right tool makes the job much faster.
What should I do if the shock absorber rod rotates when unscrewing?
If a standard hexagon does not hold, use a special vice with soft jaws or a gas wrench, holding the rod in a vice. You can also try to fix the rod by inserting a long bolt or hexagon into it through the hole in the rod, if the design allows it. The main thing is not to break the thread on the rod itself.
