Rear shock absorbers Nissan Almera G15 - one of the key elements of the suspension, on which not only comfort, but also control safety depends. Over time, they wear out: knocking noises appear, handling on uneven surfaces deteriorates, and the car begins to “sag” under load. If you notice these signs, it's time to think about replacement. A car service center will charge from 3 to 6 thousand rubles for such work, but if you have the tools and minimal skills, you can do it yourself, saving time and money.
In this article we will analyze the entire process from A to Z: how to choose high-quality shock absorbers for Almera G15, what tools are needed, how to properly remove old parts and install new ones, and what to pay attention to so as not to repeat typical mistakes. We took into account all the design nuances of this particular model - from fastening features to recommendations for running in after replacement. If you've never done suspension repair, don't worry: our guide is designed for beginners, but will also be useful for experienced car owners.
Signs of wear on the rear shock absorbers on a Nissan Almera G15
The first question that owners have is: how do you know when it’s time to change the shock absorbers? On Almera G15 (especially after 80–100 thousand km), wear symptoms appear gradually, and many attribute them to “road features.” However, ignoring them is dangerous - it directly affects the braking distance and stability of the car.
The main signs that the rear shock absorbers are out of order:
- 🔊 Knocks or squeaks in the rear of the body when driving over bumps (even small ones). Most often heard from the trunk.
- 🌊 "Rocking" of the body after overcoming speed bumps or potholes, the car cannot stabilize for a long time.
- 📉 Rear sag when loading the trunk or passengers (it is visually noticeable that the ground clearance has decreased).
- 🚗 Deterioration in handling at speed: the car “floats” along the lane, especially in crosswinds.
- 💧 Oil leaks on the shock absorber body (visible upon inspection - if the rod is wet, the part is definitely faulty).
On Almera G15 With a mileage of more than 120 thousand km, shock absorbers often “die” in pairs - if one fails, the second is most likely also on the verge. It is recommended to change them at the same timeto avoid imbalance in the suspension. You can check the condition with a simple test: press firmly on the rear bumper and release. If the body makes more than 1-2 vibrations, it’s time to change the shock absorbers.
⚠️ Attention: On Nissan Almera G15 With ABS, faulty shock absorbers can cause false alarms when braking on rough roads. This is due to changes in suspension geometry and wheel sensors.
Which shock absorbers to choose for Nissan Almera G15: original vs analogues
Selecting spare parts is half the success. On Almera G15 (2012–2018) two types of shock absorbers were installed: oil (softer, cheaper) and gas-oil (harder, but more durable). Original parts from Nissan have the following article numbers:
- 📦 Oil:
56210-BM40A(right) and56211-BM40A(left). - 💨 Gas-oil:
56210-4M50AAnd56211-4M50A.
However, the original is not always justified - its price starts from 4-5 thousand rubles per piece. As an alternative, you can consider proven analogues:
| Brand | Article | Type | Price (per piece), ₽ | Features |
|---|---|---|---|---|
| KYB | 343283 / 343284 |
Gas-oil | 3 200–3 800 | Stiffer than the original, but more durable. Popular among taxi drivers. |
| Monroe | G4486 / G4487 |
Gas-oil | 3 500–4 000 | Softer KYB, good price/quality balance. |
| Sachs | 315 384 / 315 385 |
Oily | 2 800–3 300 | Budget option, suitable for a quiet ride. |
| Boge | 23-T1-033 / 23-T1-034 |
Gas-oil | 3 900–4 500 | Premium segment, resource up to 150 thousand km. |
When choosing, pay attention to rigidity: if you drive mostly around the city, oil shock absorbers (Sachs) will be more comfortable. For an aggressive driving style or bad roads, it is better to take gas-oil ones (KYB or Boge). On Almera G15 with the 1.6 (K4M) engine, the rear suspension is initially softer than on the 1.5 (H4M) version - this should be taken into account when selecting.

Tools and materials for replacing rear shock absorbers
To change shock absorbers to Nissan Almera G15 do it yourself, you will need a standard set of tools, but there are also several specific devices. Without them, the process may be delayed or even become impossible.
Required tool:
- 🔧 Set of sockets and keys:
10 mm,12 mm,14 mm,17 mm,19 mm(preferably with a ratchet). - 🔩 Extension and universal joint for heads (for access to the upper mount).
- 🛠️ Shock absorber spring remover (required! Without it, removing the spring is dangerous).
- 🔨 Hammer and chisel (may be needed to unscrew stuck nuts).
- 🧲 Torque wrench (for proper tightening of fasteners).
- 🔧 Socket wrench on
6 mm(for the rod locking bolt).
Additional materials:
- 🛢️ WD-40 or similar penetrating lubricant (for treating rusty joints).
- 🧴 Graphite or copper grease (for processing the threads of new shock absorbers).
- 🧹 Rags and a metal brush (for cleaning seats).
- 🔋 Jack and stops (for lifting the car). A standard “bottle” jack from the trunk will also work, but it is better to use a rolling one.
If you don't have a spring puller, don't try to get by without it — a compressed spring can cause serious injury if uncontrolled. Such a tool can be rented at a car service center or purchased (costs from 1,500 rubles).
Before starting work, take a photo of the location of all fasteners and wires under the hood - this will help avoid confusion during assembly, especially if this is your first time replacing shock absorbers.
Step-by-step instructions: how to remove old shock absorbers
The process of replacing rear shock absorbers with Nissan Almera G15 can be divided into two stages: dismantling old parts and installing new ones. Let's start with the first one. Important: it is better to carry out work on a flat surface (garage or overpass) and with an assistant - some operations are difficult to perform alone.
Step 1: Preparing the machine
- Secure the front wheels with chocks and engage first gear (or “P” on automatic transmission).
- Loosen the rear wheel nuts, but do not remove them completely.
- Raise the rear of the car with a jack and place it on reliable supports (for example, wooden blocks). Never work under a machine that is supported only by a jack!
- Remove the rear wheels.
Step 2. Removing the shock absorber
- 🔧 Unscrew the two nuts securing the shock absorber to lower arm (key to
17 mm). They can be very tight - use an extension and a lever. - 🔩 In the cabin, under the back seat, find upper shock absorber mount. To access it, you will have to remove the trunk trim (it is held on by plastic clips).
- 🔄 Unscrew the three nuts of the upper fastening (the key is on
12 mm). This is where the gimbal joint comes in handy - space is limited. - 🧲 Carefully remove the shock absorber along with the spring. Be careful - the spring is under tension!
Step 3. Disassembling the shock absorber
- 🛠️ Install the shock absorber into the spring remover and compress the spring until the tension is released.
- 🔧 Unscrew the rod nut (key on
6 mm) and disassemble the assembly. Inspect the spring, support bearing and boot - if they are worn, they also need to be replaced.
Springs are free of dirt and rust|
Support bearings checked for play|
The boots and bumpers are intact (no cracks)|
The threads on the new shock absorbers are lubricated with graphite grease -->
⚠️ Attention: On Almera G15 When removing the shock absorber, the brake hose may get in the way. Do not pull on it - disconnect the hose attachment to the shock absorber (usually a plastic clamp).
Installing new shock absorbers: nuances and typical mistakes
Assembling the unit with a new shock absorber is a critical step. Here it is important not only to correctly tighten all the fasteners, but also to take into account several specific points characteristic of Nissan Almera G15.
Step 1. Assembling the shock absorber and spring
- 🔄 Install a new spring on the shock absorber, after compressing it in the puller. Make sure the lower coil of the spring fell into the groove on the shock absorber body - otherwise there will be a distortion.
- 🧲 Put on the boot and bump stop (if they come separately). On some shock absorbers (for example, KYB) the bump stop is already installed.
- 🔧 Tighten the rod nut, but do not tighten it completely - you will do this after installation on the machine.
Step 2. Installing the shock absorber on the car
- 🚗 Carefully insert the shock absorber into the seat, aligning the lower mount with the lever. Tighten the nuts
17 mmpreliminary (you will do the final tightening after lowering the machine). - 🔩 In the interior, align the upper mount with the body and tighten the three nuts
12 mm. Make sure the shock absorber is not distorted. - 🔧 Tighten the shock absorber rod nut (tightening torque -
40–50 Nm).
Typical installation errors:
- ❌ Incorrect spring orientation: If the top coil does not fit into the groove on the body, the shock absorber will knock.
- ❌ Nut tightening: this can lead to shearing of threads or deformation of the rubber bushings.
- ❌ Forgot about the brake hose: If you do not secure it back, it may rub against the spring.
After installing both shock absorbers, lower the car and press firmly on the rear of the body several times to settle the springs. Only after this can all fasteners be finally tightened to the recommended torque:
- Bottom mount:
80–100 Nm. - Top mount:
20–25 Nm.
After replacing the shock absorbers with Almera G15 Be sure to check the wheel alignment of the rear wheels. Even if the geometry is not broken, it is better to play it safe - it will take 20 minutes and save tires.
Run-in and check after replacement
New shock absorbers, especially gas-oil ones, require running-in. In the first 100–200 km they may work a little harder than usual - this is normal. However, there are a few points worth paying attention to:
What to check after replacement:
- 🔊 No knocking when driving over uneven surfaces. If they appear, check the tightness of the fasteners.
- 🚗 Machine stability at speed: after 80 km/h there should be no “yaw” in the lane.
- 📉 Body height: the rear should be flush with the front (with the trunk empty).
- 💧 No smudges on new shock absorbers (especially if they are oil-based).
If you have installed gas-oil shock absorbers (KYB or Boge), the first 500 km they will be tougher than the original ones. This is not a defect - it’s just that the new part has not yet broken in. To speed up the process, you can drive along a dirt road or speed bump at low speed.
When to go for diagnostics:
- If after replacement the car “pulls” to the side when driving in a straight line.
- If there is uneven wear on the rear tires.
- If the shock absorbers start knocking after 1–2 thousand km (possibly defective or incorrect installation).
What should I do if a knocking noise appears after replacing the shock absorbers?
Knocking can occur for several reasons:
1. **Loose fastenings** - check the tightening torque of the nuts (especially the upper fastening).
2. **Worn bushings** - If you haven't replaced the rubber bushings in the upper or lower mount, they may be loose.
3. **The spring does not fit into the groove** - remove the shock absorber and check the position of the lower coil of the spring.
4. **Defective shock absorber** - if the knocking sound is metallic and radiates into the body, the shock absorber itself may be faulty (for example, a valve is broken).
Replacement cost: do it yourself vs auto service
If you decide to change shock absorbers to Nissan Almera G15 in service, the final price will depend on several factors: the type of shock absorbers, the region and the level of the service station. Let's figure out how much replacement will cost in different options.
Self-replacement:
- 🛠️ Shock absorbers: from 6,000 to 12,000 ₽ (per pair, depending on the brand).
- 🔧 Additional spare parts: support bearings (500 ₽ each), boots (300 ₽ each), bushings (200 ₽ each). Total: ~2,000 ₽.
- 🛢️ Consumables: WD-40, lubricant - up to 500 ₽.
- 🔨 Tool: if you buy a spring puller - from 1,500 ₽ (can be rented).
Total: 8 000–15 000 ₽ (depending on the selected spare parts).
Replacement at a car service:
- 🏢 Cost of work: from 3,000 to 6,000 ₽ (per couple).
- 🛠️ Spare parts: the same prices, but the service can charge 10-20% for the “selection service”.
- 🔧 Additional services: wheel alignment (from 1,000 ₽), suspension diagnostics (from 500 ₽).
Total: 12 000–20 000 ₽.
It is most profitable to order spare parts yourself (for example, through Exist or Autodoc), and do the work yourself. However, if you do not have experience or tools, it is better to trust a trusted service - mistakes when replacing shock absorbers can be more expensive.
Savings on support bearings or bushings when replacing shock absorbers is false. These parts wear out at approximately the same rate, and if they are not replaced, after 20–30 thousand km you will have to disassemble the suspension again.
FAQ: Frequently asked questions about replacing rear shock absorbers on a Nissan Almera G15
Is it possible to change shock absorbers one at a time, or only in pairs?
It is recommended to replace shock absorbers in pairs, even if the second one is still “alive”. On Almera G15 Different stiffness of the left and right shock absorbers leads to an imbalance in the suspension, which worsens handling and accelerates wear of the second shock absorber. An exception is if one shock absorber is new (recently replaced), and the second one fails due to mechanical damage (for example, breakdown).
What is the service life of shock absorbers on Almera G15?
Service life depends on operating conditions:
- 🏙️ City (asphalt): 80–120 thousand km.
- 🛣️ Mixed cycle (city + highway): 60–100 thousand km.
- 🏔️ Bad roads (dirt roads, potholes): 40–60 thousand km.
Gas-oil shock absorbers (KYB, Boge) last 20–30% longer than oil-based ones (Sachs).
Is it necessary to do a wheel alignment after replacing shock absorbers?
On Almera G15 replacing rear shock absorbers no effect on the wheel alignment angles (camber and toe), since they are not adjustable. However, if you notice that the car is pulling to the side or there is uneven tire wear, it is worth checking the suspension geometry - perhaps the problem is in the arms or silent blocks.
Is it possible to drive with a broken shock absorber?
Technically possible, but highly undesirable. Consequences:
- ⚠️ Increase in braking distance by 10–20% (due to body “pecks”).
- ⚠️ Risk of damage to other suspension elements (springs, levers).
- ⚠️ Deterioration in controllability at speed (the car may “sway” when overtaking).
- ⚠️ Uneven tire wear (you will have to change them ahead of schedule).
If the shock absorber is leaking but still holds pressure, you can go to the service center. If it is completely out of order (the rod moves freely), driving is dangerous.
What is the difference between shock absorbers for Almera G15 1.5 and 1.6?
Structurally, shock absorbers for Almera G15 with engines 1.5 (H4M) And 1.6 (K4M) identical in fastenings and dimensions. However, there is a nuance: version 1.6 is 50–70 kg heavier, so the factory shock absorbers are a little stiffer. If you are installing non-original parts, you can choose universal parts (for example, KYB 343283/343284), but for 1.6 it is better to take gas-oil ones - they cope better with the load.
