Front shock absorbers Nissan Almera G15 - a key element of the suspension, responsible for comfort, handling and safety. Over time, even original struts wear out and lose efficiency, and ignoring problems leads to accelerated wear of other parts: ball joints, silent blocks and even tires. In this article, we will look at how to identify a malfunction, which shock absorbers to choose for replacement, and what to consider during installation.

Model G15 (2012–2019) was equipped with different types of racks depending on the configuration and sales market. For example, European versions often had a firmer setting, while Asian versions often had a softer, comfort-oriented setting. This influences the choice of analogues: what is suitable for Almera from Thailand may not suit the owner of a Russian assembly. We analyzed reviews, tests and technical data to create a checklist for the right selection.

Signs of faulty front shock absorbers

The first symptoms of strut wear are often attributed to “road conditions” or “bad tires.” However, ignoring problems leads to deterioration of braking distance by 10–20% and an increased risk of aquaplaning. Pay attention to the following signals:

  • 🔴 Oil leaks on the rack body - a clear sign of depressurization. Even if the shock absorber is still “working”, its life is running out.
  • 🔴 Knock when driving over bumps (usually on small bumps). The sound may not come from the strut, but from the support bearing or spring - diagnostics are required.
  • 🔴 Body rocking after hitting an obstacle (more than 2–3 vibrations). A normal shock absorber absorbs energy in 1–1.5 cycles.
  • 🔴 Uneven tire wear - especially along the edges of the tread. This is a consequence of a broken wheel alignment due to “sagging” struts.

For an accurate check, use the “wiggle” method: press on the car’s fender and release quickly. If the body bounces more than once, the struts are faulty. Alternative test: acceleration to 60–80 km/h and hard braking. If the car nods, the shock absorbers cannot cope with the load.

⚠️ Attention: On Almera G15 with a mileage of >100 thousand km, a knock in the front suspension can mask wear on the silent blocks of the levers. Before replacing the struts, check the play in the ball joints and the condition of the rubber-to-metal joints.
📊 How often do you check the condition of your shock absorbers?
  • Every 20 thousand km
  • Once a year
  • Only when knocking occurs
  • Never checked

Which shock absorbers are suitable for Nissan Almera G15

Original stands for Almera G15 have articles:

  • 📌 Right post: 54300-BM400 or 54300-BM40A (depending on the year of manufacture).
  • 📌 Left post: 54301-BM400 or 54301-BM40A.

The cost of the original is from 8 to 12 thousand rubles per piece. However, many owners choose analogues from trusted brands, which often exceed factory ones in terms of service life.

Brand Article (right/left) Type Average price, rub. Features

Boge 1010 328066 / 1010 328067 Gas-oil 6 000–7 500 Good stability at high speeds, but a little noisier than competitors.

When choosing, consider your driving style:

  • 🚗 City/Road: Sachs or Monroe - soft, quiet, comfortable.
  • 🏁 Sport riding: KYB or Boge - tough, but precise.
  • 💰 Budget option: Febi (22703/22704) or TRW (JGM1041T).
⚠️ Attention: On Almera G15 with engine HR16DE (1.6 L) struts are shorter than on the version with K4M (1.6 l from Renault). Check compatibility by VIN code!
💡

When purchasing shock absorbers, check the package contents: the box should contain boots, bumpers and fastening nuts. Their absence is a sign of a fake or “economy” version.

Step-by-step instructions for replacing front shock absorbers

Replacing racks with Almera G15 requires a minimum set of tools and skills to work with the suspension. On average, the procedure takes 3–4 hours for a pair of shock absorbers. You will need:

  • 🔧 Jack and stops (or lift).
  • 🔧 Set of heads (10, 12, 14, 17, 19 mm) and collars.
  • 🔧 Spring remover (required!).
  • 🔧 Torque wrench (for tightening nuts with a torque of 50–60 N m).
  • 🔧 WD-40 or a similar composition for “stuck” bolts.

Loosen the wheel bolts (do not remove!)

Disconnect the battery terminal (to prevent the airbags from deploying)

Raise the machine and secure it on stands

Remove the wheel and clean the suspension elements from dirt -->

Step 1: Removing the old rack

Unscrew the shock absorber rod nut (you will need to hold the rod with a 6 or 7 mm wrench). Then disconnect the lower mount to the steering knuckle (2 x 17mm bolts). The upper nuts attaching to the body (3 pieces per 12 mm) are unscrewed from the engine compartment. Be careful: the spring is under tension!

Step 2. Disassemble the rack

Secure the post in a vice and compress the spring with a puller. Unscrew the rod nut, remove the support bearing, cup and spring. Inspect bumper and boot — at the slightest cracks, replace them.

Step 3. Installing a new shock absorber

Transfer the parts from the old strut to the new one (spring, cup, bearing). Make sure marks on the spring coincide with the grooves on the cup - this will prevent skewing. Reassemble the rack in reverse order, using a torque wrench to tighten the nuts.

Step 4. Installation on the car

Install the stand into place, starting with the top fasteners. Tighten the nuts first, then lower the car onto the wheels and finally tighten all connections with a force of 50–60 Nm. After replacement, be sure to perform wheel alignment - even if outwardly the wheels are straight.

What to do if the stem nut does not unscrew?

Use a penetrating lubricant (eg Liqui Moly LM-40) and give it time to act (10–15 minutes).

If the nut is “slipped”, try heating it with a hair dryer - the metal will expand and the connection will weaken.

As a last resort, carefully cut off the nut with a grinder, but be careful not to damage the threads on the rod.

Common mistakes when replacing shock absorbers

Even experienced craftsmen sometimes make mistakes that lead to premature failure of racks or deterioration in controllability. Here are the most common:

  • 🔧 Incorrect tightening of nuts — overtightened connections deform the silent blocks, and weak ones lead to play. Always use a torque wrench!
  • 🔧 Ignoring the support bearing — its resource is comparable to that of a stand. If the bearing is worn out, the new shock absorber will last 2 times less.
  • 🔧 Installing the spring upside down - on Almera G15 The upper coil of the spring is narrower than the lower coil. Mixing up the sides will result in uneven stiffness.
  • 🔧 No bleeding of oil shock absorbers — before installation, they need to be fully compressed/uncompressed 3–5 times, otherwise failures in operation are possible.

Critical error: using struts from other Nissan models (for example, from Note or Tiida). Despite the external similarity, they have a different damping characteristic and rod length, which will lead to suspension imbalance.

One more nuance - quality of rubber elements. Cheap boots and bumpers crack after 10–15 thousand km, letting dirt into the strut. The optimal choice is kits from Corteco or Febi.

Comparison of oil and gas shock absorbers for Almera G15

The choice between oil and gas (or gas-oil) struts depends on operating conditions. Let's look at the pros and cons of each type:

Parameter Oil shock absorbers Gas/gas-oil
Comfort ⭐⭐⭐⭐⭐ (soft, absorbs small irregularities well) ⭐⭐⭐ (tougher, but more accurate)
Stability at speed ⭐⭐ (sway when turning) ⭐⭐⭐⭐⭐ (minimal rolls)
Resource 40–60 thousand km (sensitive to overheating) 80–120 thousand km (resistant to loads)
Price 20–30% cheaper More expensive, but justified for sporty driving
Noisiness Quiet May knock on small bumps

For most owners Almera G15 optimal choice - gas oil struts (For example, KYB Excel-G). They combine the comfort of oil and the reliability of gas. The exception is cars with mileage >150 thousand km: here it is better to install oil shock absorbers, since they are less demanding on the condition of the suspension.

💡

If you drive mainly around the city with an asphalt surface, oil struts will last longer than gas struts due to less heat.

When do you need to replace support bearings?

Support bearing on Almera G15 included in the design of the upper support of the rack. Its service life is 80–100 thousand km, but when driving on bad roads it fails earlier. Signs of malfunction:

  • 🔊 Crunching sound when turning the steering wheel (especially on site).
  • 🔊 Knock in the engine compartment when passing speed bumps.
  • 🔊 Vibration on the steering wheel when driving over uneven surfaces.

Replacing the bearing is possible separately from the stand, but requires complete disassembly of the support. The cost of the original bearing is about 2,500 rubles (54303-BM400). Analogues from SKF (VKBA 3560) or FAG will cost less (1,200–1,800 rubles), but are not inferior in quality.

When installing a new bearing:

  1. Check status rubber spacer between the support and the body - it should not be cracked.
  2. Apply grease (For example, Molykote G-4500) to the seat.
  3. Tighten the stem nut only after complete assembly of the rack, otherwise the bearing will be deformed.

Shock absorber maintenance: how to extend service life

Rack service life Almera G15 depends not only on the quality of the parts, but also on the operating conditions. The following measures will help extend their life by 20–30%:

  • 🛣️ Avoid sharp impacts about curbs or holes. Even one strong impact can damage the shock absorber valves.
  • 🚿 Wash your pendant in winter — salt and reagents destroy anthers and rubber seals.
  • 🔧 Check the tightness of the fasteners every 10 thousand km. Vibration can loosen the nuts.
  • 🔥 Don't overload the car. Exceeding the permissible weight (450 kg on the front axle) accelerates wear of the struts by 2–3 times.

Pay special attention anthers and bumpers. Their damage leads to dirt getting into the shock absorber and oil leakage. When inspecting, pay attention to:

  • 🔍 Cracks or tears in the rubber.
  • 🔍 Traces of oil on the stand body.
  • 🔍 Deformation of the bump stop (it must retain its “mushroom” shape).

If you often drive on dirt roads, install additional protective covers on racks (for example, from Husky Liners). They prevent abrasive wear from sand and stones.

FAQ: Frequently asked questions about Almera G15 front shock absorbers

Is it possible to install shock absorbers only in the front if the rear ones are still normal?

Not recommended. Different rigidity of the axle struts impairs handling, especially at high speeds. If budget is limited, replace at least a couple on one axle (left and right).

Which brand of shock absorbers is the most reliable for Almera G15?

According to test results and owner reviews, the best options are:

  1. KYB - for active driving.
  2. Sachs - for the city.
  3. Monroe - for comfort.

Original racks Nissan often inferior to analogues in terms of resource.

Is it necessary to do a wheel alignment after replacing shock absorbers?

Definitely! Even if you haven't touched the control arms or tie rods, a new strut may change your wheel alignment. A wheel alignment deviation of 0.5° accelerates tire wear by 20–30%.

Is it possible to restore old shock absorbers?

Theoretically, yes - some workshops offer to overhaul the struts and replace the seals and oil. However, on Almera G15 this is not economically feasible: the cost of restoration is comparable to the price of a new middle-class shock absorber (for example, Febi or TRW).

Why did the car become stiffer after replacing the struts?

Possible reasons:

  • Gas shock absorbers are installed instead of oil ones.
  • The support is incorrectly assembled (the bearing is overtightened).
  • The silent blocks of the levers are worn out (they transmit vibration to the body).

Check the tightness of all fasteners and the condition of the rubber-metal elements.
