Replacing shock absorbers with Nissan Almera Classic - a task that sooner or later faces every owner of this popular sedan. Despite the reputation of a reliable car, the suspension requires attention after 80-100 thousand km, and in Russian road conditions this period is often reduced to 60-70 thousand km. Unlike more modern models Almera, the classic version (N16) has a simple design, which allows you to replace it yourself with a minimum set of tools.

In this article, we will analyze not only the step-by-step process of replacing front and rear shock absorbers, but also tell you how to choose the right spare parts, avoid common mistakes and extend the life of the new suspension. We will pay special attention to the nuances that are often missed in standard instructions: for example, why a knock may appear after replacement, how to check the functionality of the racks without removing them, and when replacement is really required support bearings or anthers.

Signs of shock absorber wear: when is it time to change?

The first symptoms of faulty shock absorbers on Almera Classic often go unnoticed, since the deterioration in controllability occurs gradually. However, ignoring problems leads to accelerated wear of other suspension elements - from step bearings to ball joints. Pay attention to the following signals:

  • 🚗 Increased braking distance — worn shock absorbers reduce the grip of the wheels on the road, especially on uneven surfaces.
  • 🌀 "Sagging" of the body When braking or accelerating sharply, the front or rear of the car noticeably “bites.”
  • 💦 Oil stains on the strut body - a sign of oil seal destruction and leakage of working fluid.
  • 🔊 Knocks or squeaks when driving over speed bumps - they often indicate wear on the bushings or supports.
  • 🌪️ Body rocking after hitting a bump (more than 2-3 vibrations) - a clear sign of loss of damping properties.

For an accurate diagnosis, use swing test: Press firmly on the car fender and release. If the body oscillates more than 1-2 times, the shock absorber requires replacement. On Almera Classic with mileage over 100 thousand km it is also recommended to check spring condition - they can sag or burst, which increases the load on the racks.

⚠️ Attention: If, after replacing the shock absorbers, a knock appears in the front, check the tightening torque of the upper strut nut (should be 40-50 Nm) and the condition support bearing. On N16 it often fails at the same time as the struts.
📊 How often do you check the condition of the suspension?
  • Every 10 thousand km
  • Once a year
  • Only when knocking occurs
  • Never

Choice of shock absorbers: original vs analogues

On Nissan Almera Classic (N16) two types of shock absorbers were installed: oil (softer, cheaper) and gas-oil (harder, but more durable). Original spare parts from Nissan have articles:

  • 📌 Front left: 54300-4M000 (oil) / 54300-4M001 (gas-oil)
  • 📌 Front right: 54301-4M000 / 54301-4M001
  • 📌 Rear: 54500-4M000 (pair set)

Among analogues, brands that have proven themselves well are:

Brand Type Article (front) Article (rear) Average price, rub.
Kayaba (KYB) Gas-oil 334306 / 334307 344379 3 200–4 500
Monroe Oily G4487 / G4488 G4490 2 800–3 800
Sachs Gas-oil 313 503 / 313 504 313 505 4 000–5 500
BOGE Oily 10-041296 / 10-041297 10-041298 3 500–4 200

Critical error: shock absorbers from Almera N15 or G15 cannot be installed on the Almera Classic N16 - they have a different stroke length and mounting, which will lead to a violation of the suspension geometry. Also avoid cheap Chinese analogues (for example, Febi or TRW in the low price segment) - their resource rarely exceeds 20-30 thousand km.

When choosing, consider your driving style:

- Oil-based ones are suitable for urban use Monroe or BOGE — they are softer and quieter.

- For aggressive driving or bad roads, gas-oil ones are better KYB or Sachs — they are tougher, but they hold the road more accurately.

- If you are planning to install spacers to increase ground clearance, choose shock absorbers with increased travel (for example, KYB Excel-G).

Necessary tools and preparation for replacement

To replace shock absorbers yourself Almera Classic you will need:

Spring puller (required!)|Jack and stops (minimum lifting capacity 2 tons)|Socket wrenches 17, 19, 21 mm|Socket 12 mm for stabilizer link|Torque wrench (for tightening with the correct torque)|WD-40 or equivalent for loosening stuck nuts|Hammer and chisel (in case of problems with bolts)-->

Before starting work, complete the following steps:

  1. Place the car on a level surface, tighten the handbrake and place chocks under the rear wheels.
  2. Loosen the wheel nuts before jacking up - this will prevent the bolts from turning.
  3. Treat all threaded connections (especially the upper strut nut and hub bolts) with WD-40 1-2 hours before starting work.
  4. If you change the front struts, be sure to disconnect the negative terminal of the battery - this will prevent the airbag from triggering if it is accidentally closed (on the N16, the impact sensors are located next to the pillars).
⚠️ Attention: Never use “homemade” type spring ties (for example, made from wire or cable). On Almera Classic The spring compression force exceeds 200 kg - when the tie comes off, injuries are inevitable. Use only professional ties with a screw mechanism.

If you are planning a replacement rear shock absorbers, please note that on N16 they are attached not only to the body, but also to rear suspension beam. To access the bottom bolt, you will need to remove the wheel and bend the guard. Also prepare new mounting bushings (article 54528-4M000) - they often wear out and cause knocking noises.

Step-by-step replacement of front shock absorbers

The process of replacing the front struts with Almera Classic takes 2-3 hours (both sides). Follow the instructions:

  1. Removing the stand:

    Raise the car on a jack and remove the wheel. Unscrew the two bolts securing the rack to steering knuckle (19 mm wrench). Then unscrew the nut stabilizer links (12 mm wrench) and three nuts securing the strut to the body (12 mm wrench). Lower the jack and the strut will come out along with the spring.

  2. Disassembling the rack:

    Place the stand in a vice and compress the spring with zip ties until a gap appears between the coils. Unscrew the top nut (21 mm wrench) and disassemble the assembly. Please note the condition support bearing (article 54340-4M000) - if it plays or creaks, replace it.

  3. Installing a new rack:

    Transfer all the parts (spring, cup, boot) to the new strut. Tighten the top nut to torque 40-50 Nm. Install the rack into place, starting with the attachment to the body. Do not tighten the bolts completely until the car is lowered onto the wheels!

  4. Completion:

    After installing the wheel, lower the vehicle and pump up the racks — Press the wing sharply 3-5 times. Then tighten all bolts to the correct torque (see table below).

element Tightening torque, Nm
Upper strut nut 40–50
Bolts for fastening to the steering knuckle 80–100
Stabilizer link nut 40–50
Bolts securing the strut to the body 20–25
💡

If the spring does not fit straight into the cup when assembling the post, use a rubber mallet to adjust the position. Do not apply excessive force as this may damage the spring coils.

Replacing rear shock absorbers: nuances and mistakes

Rear shock absorbers Almera Classic They are easier to change than the front ones, but they have their own characteristics. The main difficulty is access to the bottom bolt, which often sticks to the beam. Work order:

  1. Lift the rear of the car and remove the wheel. Unscrew the two bolts securing the shock absorber to the body (14 mm wrench).
  2. Loosen the bottom bolt (17 mm wrench), but do not unscrew it completely - first support the shock absorber with your hand so that it does not fall.
  3. Remove the shock absorber and check the condition bushings And compression progress buffer (article 54529-4M000). If worn, replace them.
  4. Install the new shock absorber, starting with the lower mount. Tighten the bolts only after the vehicle is lowered onto its wheels.

Typical mistakes when replacing rear struts:

- Ignoring bushings - they wear out faster than shock absorbers and cause knocking.

- Incorrect tightening - the bottom bolt must be tightened to a torque 80-100 Nm, otherwise it will unscrew itself.

- No pumping — new shock absorbers need to be pumped before installation (fully compress and release the rod 5-6 times).

What happens if you don't bleed the shock absorbers?

Unbleeded struts may have air pockets, which leads to uneven operation (one side is stiffer than the other), poor handling, and premature failure. On the Almera Classic this is especially noticeable when passing speed bumps - the car will “bounce”.

Wheel alignment adjustment after replacement

After replacing the shock absorbers with Nissan Almera Classic necessarily needs to be checked and adjusted wheel alignment. Even if you haven't touched the tie rods or control arms, the new struts change the suspension geometry. Adjustment features:

  • 🔧 On N16 the camber is adjustable eccentric bolts on the rack (front wheels). The rear wheels are not adjustable - there is a fixed angle.
  • 📏 Normal angle values for Almera Classic:
    • Front wheel camber: -0°30' ± 30'
    • Front wheel alignment: 0° ± 10' (or 0–2 mm according to the bench scale)
  • ⚠️ If after replacing the struts the car pulls to the side, check:
    • Correct installation step bearing (it should be oriented with the label facing up).
    • Condition steering tips And traction - they could wear out in parallel with the racks.

The cost of wheel alignment adjustment at a service station for Almera Classic is 1,500–2,500 rubles. If you are doing the work yourself, use laser stand or cord method (less accurate, but suitable for preliminary testing).

💡

After replacing shock absorbers, avoid sharp maneuvers and high speeds during the first 100 km - the new struts should “get used to” the operating conditions.

Caring for a new suspension: how to extend its service life

To keep the shock absorbers on Almera Classic last longer, follow the recommendations:

  • 🚿 Suspension washing — in winter, clean the racks from salt and reagents at least once every 2 weeks. Use anti-corrosion compounds (For example, Molykote or Liqui Moly) for processing the rod.
  • 🛣️ Driving style — avoid sudden braking on speed bumps and overcoming potholes at high speed. On the N16, the optimal speed for uneven surfaces is no more than 20 km/h.
  • 🔧 Checking fasteners — every 10 thousand km, check the tightening torque of the strut bolts (especially the lower ones). Vibrations can weaken connections.
  • 🌡️ Temperature control — if the stand gets very hot (more than 60°C), this is a sign of a malfunction. Check the oil level (for oil shock absorbers).

Average life of shock absorbers for Almera Classic:

- Original oil ones: 60–80 thousand km.

- Gas-oil analogues (KYB, Sachs): 100–120 thousand km.

- Budget analogues: 30–50 thousand km.

⚠️ Attention: If after replacing the shock absorbers there is squeaking sound when turning the steering wheelmost likely the problem is support bearing or insufficient lubrication of the upper cup. On N16 this is a typical fault - the bearing requires replacement every 80-100 thousand km.

FAQ: Frequently asked questions about replacing shock absorbers

Is it possible to replace only one shock absorber if the second one is still normal?

Not recommended. Even if the second shock absorber is visually in good working order, its characteristics have already changed (wear of seals, loss of oil viscosity). Different stiffness of the struts will lead to poor handling and uneven tire wear. An exception is if the second shock absorber is new (mileage less than 10 thousand km).

Do the springs and shock absorbers need to be replaced?

Be sure to check the condition of the springs. On Almera Classic they often sag or burst after 150 thousand km. Signs of malfunction:

  • Visual sagging of the body (the gap between the wheel and the arch is less than 35 cm).
  • Cracks or corrosion on coils.
  • Uneven front/rear vehicle height.

If the springs are normal, they can be left, but be sure to check the rubber gaskets (article 54322-4M000 for the front ones, 54527-4M000 for the rear).

What gas is in gas-oil shock absorbers for Almera Classic?

In most gas-oil shock absorbers for Nissan Almera Classic (For example, KYB Excel-G or Sachs Super Touring) is used nitrogen at a pressure of 8–12 bar. This is an inert gas that prevents oil foaming and provides more stable operation under high loads. Unlike air, nitrogen does not oxidize the internal surfaces of the rack.

What should I do if a knocking noise appears after replacing the shock absorbers?

Knocking after replacement can have several reasons:

  1. Loose fasteners — check the tightening torque of all bolts (see table above).
  2. Support bearing wear - on N16 it often fails simultaneously with the racks. Check the play by shaking the strut by hand with the hood open.
  3. Damaged bushings — if the bushings of the rear shock absorbers have not been replaced, they may knock.
  4. Incorrect boot installation - if it is twisted or torn, this leads to dirt getting into the rack.

If the knocking noise does not go away, check step bearings And lever silent blocks - they could wear out in parallel.

Is it possible to restore old shock absorbers?

Theoretically yes, but in practice it is impractical. Recovery includes:

  • Replacing the oil seal and oil (for oil struts).
  • Checking the rod for wear and polishing.
  • Nitrogen filling (for gas-oil).

However, even after restoration, the service life of the strut will be no more than 20–30 thousand km, and the cost of work often exceeds the price of a new shock absorber in the budget segment. The exception is rare or expensive racks (for example, for sports modifications).
