Car suspension Nissan Almera experiences enormous loads, especially on domestic roads. One of the weakest and at the same time critical points of the design is the front shock absorber strut. When you notice extraneous knocks when driving over speed bumps or feel that the steering wheel has begun to “float”, the problem most often lies in the wear of this unit. Ignoring these symptoms can lead to accelerated tire wear, broken control arms, and even loss of control at high speeds.
The process of replacing the front strut with Nissan Almera does not require super-complex equipment, but it is painstaking and requires strict adherence to the sequence of actions. Many owners try to save money by changing only bushings or anthers, but complex replacement an assembled unit or with a spring transfer often turns out to be a more reliable and safe solution. In this article we will look at all the nuances: from choosing high-quality spare parts to the intricacies of tightening bolts.
Symptoms of malfunction and diagnosis of the rack
You can determine that it’s time to change the front struts by a number of characteristic signs that appear both while driving and during visual inspection. The most obvious signal is a knocking or dull metallic impact in the area of the front wheels when driving over uneven surfaces. Often owners Nissan Almera These sounds are confused with a malfunction of the levers or silent blocks, so it is important to conduct a thorough diagnosis.
The second important symptom is deterioration in controllability. The car begins to “nod off” when braking, there is a strong roll in corners, and the steering wheel can give off excess vibration to your hands. It is also worth paying attention to the appearance of the shock absorbers: the presence of oil leaks on the strut body is a clear sign that O-rings they have lost their tightness and the unit requires replacement.
Sometimes the problem can be hidden and the knocking noise is only heard under certain conditions. In such cases, a simple test will help: press firmly on the front of the body above the wheel and release sharply. If the car makes more than one oscillation up and down, it means that the strut does not dampen the inertia of the spring and shock-absorbing properties completely lost.
⚠️ Attention: Do not try to drive with completely “dead” struts, even if the knocking seems quiet. This increases braking distance and can lead to skidding on wet roads, which is especially dangerous for front-wheel drive sedans such as Nissan Almera.
Selection of spare parts: original or analogues?
Spare parts market for Nissan Almera offers a huge range of options, which often confuses owners. Original from Nissan (part number usually starts with 54006) provides maximum comfort and resource, but is quite expensive. Many owners choose proven analogues that offer excellent value for money.
Among the popular brands that have proven themselves well on models Nissan, we can highlight Kayaba (KYB), Sachs and Monroe. These manufacturers often supply their products on an assembly line, so their racks are almost as good as the originals. However, you should be careful with cheap Chinese analogues, which can fail after 10-15 thousand kilometers.
When choosing, it is important to decide on the type of replacement: change only the shock absorber itself or buy an assembled strut. The assembled kit includes a spring, support, bearing and boot. This greatly simplifies the work, since disassembling the spring on the stand is not required. If you are changing the rack yourself without special equipment, the option assembled - the only right decision.
Below is a comparison table of popular brands for Nissan Almera G15:
| Brand | Product type | Indicative resource | Features |

Necessary tools and preparation
Before starting work, it is necessary to prepare the workplace and tools. To replace the front strut with Nissan Almera you will need a standard set of wrenches, a ratchet with extensions and sockets. The 17, 19, 21 and 24 mm heads are critical, as these are where the main suspension components are tightened.
Pay special attention wheel stoppers and a jack. The car must be securely fixed on stands (“goats”), since working under the car on one jack is strictly prohibited. You will also need a special spring puller if you plan to change only the shock absorber. If you are purchasing a complete strut, this tool is not needed, but it may be useful for replacing the support bearings.
Don't forget about penetrating lubricant (such as WD-40 or equivalent), which must be used to treat all threaded connections at least 15-20 minutes before unscrewing. The bolts that secure the strut to the steering knuckle often become tightly stuck due to road chemicals and dirt.
☑️ Preparing to replace the rack
Step-by-step instructions for dismantling
We begin the process by lifting the car and removing the front wheel. Inspect the mounting area: you need to unscrew the nuts that secure the bottom of the strut to the steering knuckle. Typically these are two bolts that can be hidden under the splash guard. Use a 19 mm or 21 mm socket, depending on the year of manufacture Nissan Almera.
Next, we move on to the upper part of the rack, which is attached to the body through a glass in the engine compartment. Open the hood and locate the three shock absorber mounting nuts on the body glass. It is better to unscrew them when the wheel is under load so that the spring does not “shoot out”, but when using the rack assembly this moment is less critical. It is recommended to loosen the nuts and then completely unscrew them after dismantling the lower part.
The most difficult step is disconnecting the strut from the steering knuckle. If the bolts do not fit, do not use excessive force to avoid stripping the threads. Use a special lever puller or tap the knuckle eye with a hammer (not the bolt thread!). After removing the bottom bolts, the rack should come out of the seat freely.
What to do if the bolts are stuck?
If the bolts attaching to the knuckle do not unscrew, try heating them with a blowtorch or a hair dryer. Sometimes the “blow” method helps: apply a strong blow with a hammer through the spacer towards the bolt to break the oxidation layer. As a last resort, you can use a hydraulic puller.
After the bottom bolts are unscrewed, carefully remove the strut from the arch. Be careful not to damage the brake hose and ABS wiring that may be located nearby. If you are replacing the entire strut assembly, you can immediately throw the old assembly into the trash after first checking the condition of the brake pads and discs.
⚠️ Attention: When removing the spring (if you are changing only the shock absorber), use special ties. A spring under load has tremendous energy, and accidental compression can cause serious injury or property damage.
Installation of a new rack and final operations
Before installing the new strut assembly, check the condition of the support bearing and boot. If you purchased a complete kit, these parts are already installed. If you are replacing only the shock absorber, transfer the old spring to the new strut using special couplers, and make sure that the spring is seated correctly.
Install the new strut into the engine compartment and tighten the three upper nuts securing it to the body cup. Then insert the bottom of the strut into the steering knuckle and install the new bolts. It is important to use new bolts, since they are often disposable (with break-off heads or special threads). Tighten all connections to the torque recommended by the manufacturer.
The ideal moment to finally tighten the bolts is when the car is on its wheels on a level surface. In this position, the suspension is in working position, and the rubber silent blocks will not twist after installation. This will extend the life of the suspension elements and prevent squeaks.
Before final tightening the bolts securing the strut to the knuckle, ask an assistant to shake the steering wheel left and right to make sure that the steering rack and tips are not jammed and there is no excess stress in the nodes.
Wheel alignment and operation check
After replacing the front strut with Nissan Almera it is necessary to complete the procedure wheel alignment. Any intervention in the suspension geometry changes the wheel alignment angles. If you ignore this step, you will quickly “eat up” the new tires, and the car will pull to the side when driving in a straight line.
It is important to note that on some models Nissan Camber adjustment may be limited by standard bolts. In this case, it may be necessary to install adjusting bolts or eccentric washers for fine adjustment. Make sure that the technician at the stand knows the specifics of your body and suspension.
Once all work is completed and angles are adjusted, test drive. Pay attention to the behavior of the steering wheel, the absence of knocks and the smoothness of the ride. If you feel vibration in the steering wheel or uneven braking, return to the dealership to have the tightening and alignment rechecked.
Replacing the A-pillar is not only about eliminating the knock, but also about restoring driving safety. Always perform a wheel alignment after tampering with the suspension.
Common mistakes when replacing
Despite its apparent simplicity, beginners often make mistakes that can lead to repeated repairs in a short time. One of the most common problems is improper tightening of the strut-to-knuckle bolts. If you tighten them in the raised state, when lowering the car, the rubber bushings will be twisted, which will lead to their rapid destruction.
Another mistake is using old nuts and bolts. The threads on these elements often become deformed, and repeated use may cause the nut to unscrew itself during movement. Also, do not neglect cleaning the seats from rust and dirt before installing a new part, as this can disrupt contact and cause corrosion.
Sometimes owners forget to check the condition of other suspension elements. A replaced strut with more rigidity may reveal hidden defects in the arms or tie rod ends that were previously masked by shock absorber wear. Therefore, when replacing a strut, it is recommended to conduct a full diagnosis of the chassis.
⚠️ Caution: Never use a hammer to drive strut bolts directly into the threads or head of the bolt. This distorts the metal and the bolt may become stuck or break when tightened again.
FAQ: Frequently asked questions
How long does it take to replace a front strut on a Nissan Almera?
For an experienced technician, replacing one stand assembly takes about 40-60 minutes. If you are doing this yourself for the first time, allow 1.5-2 hours on each side, as you will have to deal with stuck bolts and study the instructions.
Is it possible to change racks one at a time?
Technically it is possible, but experts strongly recommend changing the struts in pairs (both front or both rear). Wear always occurs evenly, and if one strut is worn out, the second is most likely in the same condition. Different suspension stiffness can worsen handling.
Do I need to do a wheel alignment after replacement?
Yes, definitely. Replacing the strut changes the suspension geometry, and without adjusting the wheel alignment angles, you risk quickly ruining the new tires and having handling problems.
Which is better: a complete strut or just a shock absorber?
To replace it yourself without a special stand, it is definitely better to take the rack assembly. This eliminates the risk of injury when compressing the spring and saves time on disassembling the unit. If you are a professional and have a tool, you can only buy a shock absorber.
How often do you need to replace the front struts on a Nissan Almera?
The average service life of original struts is 80-100 thousand kilometers, but this depends on the quality of the roads and driving style. When the first signs of knocking or oil leaks appear, the inspection should be carried out immediately.
Why is the new strut knocking?
If the knocking noise appears immediately after replacement, check the tightness of the bolts. Often the reason is that the bolts were not tightened under load. There may also be a defect in the new part or a lack of lubrication at the points where the spring contacts the support.
Regular monitoring of the suspension condition and timely replacement of worn parts is the key to safe and comfortable driving on your Nissan Almera. Don't put off repairs until the car becomes undriveable. Correctly selected spare parts and high-quality installation will restore your confidence on the road and extend the life of your entire car.
