Operation Nissan Almera generation G15 in Russian road conditions inevitably leads to suspension wear. The rear beam, although considered a fairly reliable unit, has its own weak points, among which shock absorber struts occupy a leading position. Their failure not only impairs ride comfort, but also significantly affects safety, increasing braking distance and worsening handling.
Many owners put off visiting a service center, attributing extraneous knocking noises to poor coverage, but delaying repairs can lead to the destruction of other elements of the chassis. Correct and timely replacing rear struts will allow you to return the car to its factory performance characteristics on the road and extend the life of the entire rear suspension.
In this article we will analyze in detail the symptoms of a malfunction, criteria for selecting quality spare parts and a step-by-step algorithm for self-replacement. You'll learn what tools you'll need, how to avoid common assembly mistakes, and why skimping on shock absorbers can result in serious financial losses in the future.
Symptoms of wear and diagnostics of suspension
Determine what shock absorbers on your Nissan Almera require replacement, based on a number of characteristic signs that become noticeable during active driving. The most obvious symptom is the appearance of dull knocks or knocks when driving over bumps, especially if they are repeated with each wheel or only at the rear when loading the trunk.
You should not ignore visual changes: if you notice oil smudges on the shock absorber body, this is a sure sign of a seal failure. Oil leak leads to a loss of viscosity of the working fluid and, as a consequence, to a complete failure of damping, which makes the strut “empty”.
It is important to pay attention to the car's behavior when cornering. If Nissan Almera G15 it begins to roll heavily to one side, and after passing an uneven surface the body continues to sway several times, this indicates a loss of damping properties. It is also worth checking the integrity of the anthers and bump stops, since their damage is often a harbinger of an imminent rod failure.
- The appearance of characteristic knocks and impacts from the rear when passing speed bumps
- Visually noticeable oil stains on the shock absorber body
- Increased body swing time after pressing the trunk
- Uneven wear of the rear tires and the appearance of “bumps” on the tread
⚠️ Attention: Driving with faulty shock absorbers can lead to loss of contact between the wheels and the road during heavy braking, which is critically dangerous on wet asphalt or ice.
Selection of spare parts: original or analogues?
When selecting components for pendants A dilemma arises: install original parts Nissan or trust proven analogues. Original racks are of guaranteed quality and exactly match factory specifications, but their cost is often inflated, and their service life does not always exceed high-quality analogues.
There are dozens of brands on the market offering products for Nissan Almera G15. Market leaders include Kayaba (KYB), Sachs, Monroe and Boge. These manufacturers use modern technology and materials, providing reliability comparable to the original, but often at a more attractive price.
When choosing, it is important to consider the operating conditions. If you often drive on rough roads, you should pay attention to reinforced shock absorbers or models with an increased service life. For quiet city driving, standard gas or oil struts are suitable, which will provide maximum comfort.
Never buy shock absorbers secondhand or without packaging, as the risk of running into a counterfeit or defective product is extremely high. Checking the markings and the presence of protective holograms on the packaging is a prerequisite before purchasing.
- Original: perfect match, but high price and risk of counterfeiting
- Kayaba (KYB): excellent balance between price and quality, a popular choice for Nissan
- Sachs: premium comfort, often installed at the factory, but more expensive than analogues
- Monroe: reliable and durable struts with good damping
- Original Nissan
- KYB (Kayaba)
- Sachs

Necessary tools and preparation
Before you start work, you need to prepare your workplace and tools. To replace rear struts with Nissan Almera you will need a standard mechanic's kit: a jack, support stands (goats) and a set of keys. Pay special attention to the strength of the jack, as it must support the weight of the rear of the car.
The key is to have a special tool to compress the springs. Without it, replacement is impossible, since the spring is under high pressure. Attempting to disassemble the rack without a puller may result in injury or damage to parts. Also, don't forget to use a penetrating lubricant like WD-40 to treat rusty nuts.
It is recommended to study the design of the rear beam in advance in order to understand the location of the fasteners. In some cases, the nuts may become stuck, so having a powerful wrench and extensions will greatly simplify the task. Also have a rag ready to remove dirt and oils.
- Hydraulic or screw jack with sufficient safety margin
- Set of sockets: 12, 14, 17, 19 mm and keys of corresponding sizes
- Spring puller (required!) and pry bar for working with levers
- Penetrating lubricant, metal brush and personal protective equipment
☑️ Preparing to replace the rear struts
Step-by-step instructions for dismantling
It is better to start work with one wheel so that you can compare the process with the second side and not get confused in the details. Raise the rear of the car with a jack, place a reliable support under the body and remove the wheel. Thoroughly clean the upper support mounting area from dirt and rust to avoid jamming of the nuts.
First, unscrew the shock absorber rod nut located in the trunk. To do this, you will need to hold the rod from turning with a wrench or hexagon. After this, you can go to the bottom of the rack and unscrew the bolt securing it to the steering knuckle or beam.
Carefully remove the old post from the arch. If it gets stuck, use a pry bar to pry it up lightly, but avoid hitting it hard to avoid damaging the body parts. Pay attention to the condition of the spring cup and rubber gaskets, which often require replacement along with the strut.
After removing the strut, be sure to check the condition of the spring. If it is chipped, cracked, or clearly deformed, it will also need to be replaced. Try not to leave the spring in a compressed state without a shock absorber, as this can lead to rapid wear.
⚠️ Warning: Never attempt to unscrew the stem nut while the spring is in a compressed state without removing the strut - this may result in sudden rupture and injury.
Frequent problems during dismantling
Often the stem nut rotates along with the stem. In this case, use a hexagon of the appropriate size or a special key to fix the rod. If the lower mounting bolt is stuck, use heat and plenty of lubrication, but be careful not to damage the rubber elements.
Installation of new shock absorbers and assembly
Before installing the new strut, assemble it with a new spring and rubber elements. Use a spring remover to compress until the spring releases the shock absorber cup. Make sure that the spring sits evenly in its seats and is not distorted.
Place the assembled stand in place, making sure the top and bottom are in the correct position. Insert the rod into the eye in the trunk and tighten the nut. Then screw the bottom mount to the beam. Don't tighten the bolts all the way down right away - hand tighten them first to make sure the holes are aligned correctly.
Lower the vehicle to the ground so that the spring assumes its natural position under load. Only then perform the final tightening of all fasteners with the recommended torque. Tightening under load critical to the durability of rubber silent blocks.
Repeat the procedure for the second side, being careful to use the same tools and methods. After installing both shock absorbers, check the operation of the suspension by rocking the car several times. Make sure there is no extraneous noise and the suspension travel is free.
- Reassemble the strut with the new spring, using a puller to securely compress
- Install the stand by aligning the mounting holes and tightening all the nuts
- Lower the vehicle onto the wheels to tension the spring before final tightening.
- Check for distortions and extraneous noise after assembly
Replace the spring rubber gaskets and boots even if the old ones look intact - the old material loses its elasticity and can quickly collapse, which will lead to rod corrosion.
Typical errors and technical nuances
One of the most common mistakes is replacing only one shock absorber. Shock absorbers need to be replaced in pairs, since their wear occurs approximately the same. Installing a new strut on a worn second strut can lead to uneven load distribution and poor handling.
Incorrect tightening of the mounting bolts can also cause problems. If you tighten the nuts too tightly, the rubber bushings will quickly collapse, and if you tighten them too loosely, knocking and play will occur. Use a torque wrench to control the tightening torque to avoid mistakes.
Ignoring the condition of other suspension elements when replacing struts is another common mistake. Often worn struts mask problems with stabilizers or control arms. It is recommended to carry out a full diagnostic of the chassis before starting work, so as not to return to the same place in a month.
Shock absorbers should always be replaced in pairs on the same axle, even if one of them appears to be working, to maintain suspension balance and driving safety.
It is also worth remembering about proper storage of shock absorbers. Before installation, they should not be stored upside down, as this may allow air to enter the working chamber. Store the racks in an upright position as they will be installed on the vehicle.
| element | Recommended tightening torque (Nm) | Note |
|---|---|---|
| Shock absorber rod nut | 35–45 | Keep the rod from turning |
| Beam mounting bolt | 90–110 | Tighten after lowering the car |
| Spring fastening nut | By passport | Check the condition of the rubber bands |
| Stabilizer bolt | 20–25 | Check the condition of the bushings |
⚠️ Attention: Using an old set of springs with new shock absorbers is strictly not recommended, since a sagging spring will change the ground clearance and performance characteristics of the new strut.
