Rear shock absorbers Nissan Almera G15 - a critical element of the suspension, on which not only comfort, but also control safety depends. Unlike front struts, rear shock absorbers are often left unattended until they begin to “ask for replacement” with obvious knocking or deterioration in handling. However, their condition cannot be ignored: worn dampers increase the braking distance, provoke “yaw” on uneven surfaces and accelerate the wear of other suspension parts.
In this article we will look at everything you need to know about rear shock absorbers. Almera G15: how to recognize a malfunction, which brands and models to choose for replacement, how to carry out the work yourself (with step-by-step instructions and nuances), and we will also give recommendations for extending the service life. We will place special emphasis on typical mistakes when replacing, which lead to rapid failure of new shock absorbers.
Signs of bad rear shock absorbers: when is it time to change them?
Rear shock absorbers Almera G15 wear out gradually, and many drivers get used to the deterioration of the car's behavior. However, there are clear symptoms that indicate the need for diagnosis:
- 🚗 Increased braking distance — the car “nods off” when braking sharply, the rear part rises.
- 🌀 Body rocking after driving over bumps (more than 2-3 vibrations).
- 💥 Knocks or squeaks in the rear suspension area, especially on small bumps.
- 🛣️ Deterioration in handling at high speed: the car “floats” along the lane, reacts to gusts of wind.
- 🔧 Oil leaks on the shock absorber body (visible during visual inspection).
One of the simplest tests is swing check. Click on the rear bumper Almera G15 from top to bottom and release. If the body oscillates more than 1-2 times, the shock absorbers have lost their effectiveness. Also note Uneven rear tire wear - This is an indirect sign of problems with damping.
⚠️ Attention: If after replacing the shock absorbers the car has become “harder”, this is not always a defect. New dampers (especially gas-oil ones) work tighter for the first 500–1000 km until they “grind in.” But if the rigidity persists longer, check the correct installation or the quality of the parts.
- Every 20,000 km
- Once a year
- Only when problems arise
- Never checked
Which rear shock absorbers are suitable for Nissan Almera G15: comparison of brands and models
On Almera G15 (2012–2019) shock absorbers with the following parameters were installed:
- 📏 Compressed length: ~380 mm
- 📏 Unfolded length: ~580–600 mm
- 🔩 Mounting type: bottom - eye (Ø 12 mm), top - threaded rod M12×1.25

Original shock absorbers from Nissan have an article number 56210-BM400 (right) and 56211-BM400 (left), but their price often forces owners to look for analogues. The table below contains proven analogues from leading brands:
| Brand | Article | Type | Average price (per piece) | Features |
|---|---|---|---|---|
| KYB | 344383 / 344384 |
Gas-oil | 3 500–4 200 ₽ | Stiffer than the original, long service life, popular for sport riding |
| Monroe | G4486 / G4487 |
Gas-oil | 3 200–3 800 ₽ | Softer KYB, good price/quality balance |
| Sachs | 315 382 / 315 383 |
Oily | 2 800–3 400 ₽ | Comfortable, but less durable during aggressive driving |
| Boge | SNR 3061 / SNR 3062 |
Gas-oil | 3 600–4 100 ₽ | Good stability at high speeds, rarely leaks |
When choosing, pay attention to shock absorber type:
- 💧 Oily (Sachs, Delphi) - softer, more comfortable on bad roads, but overheat under prolonged loads.
- ⚡ Gas-oil (KYB, Monroe) - stiffer, hold the road better, but may seem “oaky” on small irregularities.
A critical point for Almera G15: if the car often drives with a loaded trunk or passengers, gas-oil shock absorbers will last longer, since they “sag” less under load.
Step-by-step instructions for replacing rear shock absorbers with Nissan Almera G15
Replacing rear shock absorbers with Almera G15 easier than front struts, but requires care. To work you will need:
- 🔧 A set of sockets and keys (required)
12 mm,14 mm,17 mm). - 🔩 Spring remover (if you disassemble the shock absorber separately from the spring).
- 🛠️ WD-40 or similar penetrating lubricant.
- 🔥 Flashlight (lighting the rear suspension is often difficult).
Important: Replace in pairs - even if one shock absorber is “alive”, the second is already worn out. Different stiffness on the right and left worsens handling.

Step 1: Removing the old shock absorber
1. Remove the wheel and bend the plastic wheel arch liner (if necessary).
2. Unscrew the lower shock absorber mount (nut 17 mm on the finger). You may need to hold your finger with the key 14 mm from the reverse side.
3. In the trunk, remove the plastic plug above the shock absorber (pry it off with a screwdriver). Unscrew the top nut (12 mm) - an extension cord with a cardan will come in handy here.
4. Remove the shock absorber along with the spring (if they are not dismountable).
Step 2: Installing a New Shock Absorber
1. If the shock absorber is separate from the spring, assemble the assembly using a puller. Make sure the rubber gaskets are in the correct position!
2. Install the new shock absorber into place, starting with the top mount. Do not tighten the nut all the way.
3. Align the lower pin with the bracket and secure with a nut.
4. Tighten all fasteners only after lowering the car onto its wheels (otherwise the spring will be under tension).
⚠️ Attention: If during assembly you hear a metallic grinding sound in the area of the upper support, immediately disassemble the assembly - most likely, the rubber bushing is installed crookedly or is missing. This will lead to play and rapid wear of the new shock absorber.
Before installing a new shock absorber, clean the rod threads from dirt and apply a little graphite lubricant - this will make future replacement of the upper support easier.
Typical replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that shorten the life of new shock absorbers. Here are the most common:
- 🔧 Incorrect tightening of nuts — if you tighten the upper fastening, the rubber bushing will be deformed and play will appear. Optimal tightening torque:
25–30 Nmfor the top nut,80–100 Nmfor the bottom. - 🌀 Ignoring anthers — many people save on new boots, but old ones often crack and let dirt onto the stem.
- 🛑 Replacing only one shock absorber — different hardness on the right and left leads to uneven tire wear and deterioration of directional stability.
- 🔥 No pumping — new gas-oil shock absorbers (KYB, Monroe) need to be pumped before installation (sharply compressed/unclamped 5–6 times).
Another common problem is incompatibility with springs. For example, if you installed hard shock absorbers KYB, and the springs remain standard (soft), the suspension will “sag” under load. In this case, it is worth considering installing shortened springs (For example, H&R or Eibach), but this is already tuning that requires improvement.
What happens if you don’t bleed the shock absorber before installation?
An unpumped gas-oil shock absorber may have air pockets, due to which it will “fail” in the first hundreds of kilometers. This results in uneven wear and reduced damping efficiency. In the worst case, it can lead to oil leakage through the seals.
How to extend the life of rear shock absorbers: expert advice
The average life of the rear shock absorbers is Almera G15 - 80,000–120,000 km, but with proper operation they can be “stretched” up to 150,000 km. Here's what you need for this:
- 🛣️ Avoid sharp impacts — drive around potholes at speeds above 40 km/h, do not “land” from curbs.
- 🚗 Control your download — constant overload of the trunk (more than 200 kg) accelerates wear.
- 💧 Wash your pendant in winter — salt and reagents corrode the anthers and seals.
- 🔧 Check the fastenings — once every 20,000 km, tighten the shock absorber nuts (they may become loose due to vibrations).
Also note condition of other suspension elements:
- 🔄 Worn silent blocks rear beams increase the load on the shock absorbers.
- 🛞 Warped rims (especially after falling into holes) cause beating, which is transmitted to the dampers.
Regular suspension diagnostics (every 10,000 km) allows you to identify problems at an early stage and save on repairs. For example, replacing a boot for 500 ₽ is cheaper than a shock absorber for 4,000 ₽.
Is it worth installing non-original shock absorbers: pros and cons
Original shock absorbers Nissan for Almera G15 are expensive (from 5,000 ₽ per piece), so many people choose analogues. Let's consider their advantages and risks:
| Shock absorber type | Pros | Cons |
|---|---|---|
| Original | Guaranteed compatibility, softness, long service life | High price, not always available in stock |
| Premium analogues (KYB, Boge) | The best price/quality ratio, often exceeding the original in terms of resource | May be harsher (especially KYB) |
| Budget analogues (Fenox, Trialli) | Low price (from 1,500 ₽) | Short life (30,000–50,000 km), risk of leakage |
If you choose analogues, give preference to brands that supply parts to the assembly line Nissan (For example, KYB or Sachs). Avoid "no-name" manufacturers - their shock absorbers often have inappropriate oil viscosity, which leads to overheating and failure.
For those who want to improve handling, there is an installation option sports shock absorbers (For example, KYB Excel-G or Bilstein B4). They are stiffer, but hold the road better at high speeds. However, please note that this will require replacing springs to stiffer ones, otherwise the suspension will “sag”.
Frequently asked questions about rear shock absorbers Nissan Almera G15
Is it possible to drive if the rear shock absorber is leaking?
If the leak is small (a few drops), you can drive to the service station, but not more than 1,000–2,000 km. Severe leakage results in loss of damping, which is dangerous at high speeds. In addition, oil gets onto the brake pads and rotors, reducing their effectiveness.
Which brand of shock absorbers is the most reliable for Almera G15?
According to reviews from owners and craftsmen, the best options are:
- For comfort: Sachs or original Nissan.
- For durability: KYB or Boge.
- For budget: Monroe (good price/quality balance).
Is it necessary to do a wheel alignment after replacing shock absorbers?
On Almera G15 The rear wheels do not have camber/toe adjustment, so this procedure is not required. However, if you notice uneven tire wear after replacement, check the body geometry - the rear beam may be deformed.
Is it possible to restore old shock absorbers?
Theoretically, yes - some workshops offer a rebuild with replacement of seals and oil. However for Almera G15 this is rarely justified: the cost of restoration (2,000–3,000 rubles) is comparable to the price of a new budget shock absorber, and the service life after repair usually does not exceed 20,000–30,000 km.
Why did the car become lower after replacing the shock absorbers?
This is normal if you have installed gas-oil shock absorbers (KYB, Boge) - they have higher gas pressure, which causes the springs to compress more strongly. If the drawdown is critical (more than 2–3 cm), check:
- The springs are installed correctly (the sides are not mixed up).
- The condition of the springs - perhaps they are “tired” and require replacement.
