Nissan Almera Classic (also known as Nissan Almera N16 or Samsung SM3 in some countries) is a reliable sedan, but over time even its suspension requires attention. The rear shock absorbers on this model wear out 80–120 thousand km, and their malfunction is manifested not only by discomfort, but also by deterioration in controllability. If you notice that the car “sags” on bumps, the suspension knocks, or the rear end sways after overcoming bumps, it’s time to think about replacing it.

In this article we will look at step by step process for replacing rear shock absorbers on Almera Classic (body B10/N16), including the selection of spare parts, the necessary tools and common mistakes. The instructions are suitable for both owners with minimal repair experience and those who prefer to do everything themselves. We will pay special attention unique nuances of this model - for example, fixing the shock absorber to the body and working with springs without ties.

Signs of wear on the rear shock absorbers on a Nissan Almera Classic

The first symptoms of a malfunction often go unnoticed, especially if wear occurs gradually. However, ignoring them is dangerous: non-functioning shock absorbers increase braking distance, worsen road grip and increase the risk of aquaplaning. Here are the key signs that it's time to replace your rear struts:

  • 🔧 Shock loads when driving over even small bumps, it feels as if the car is “punching” the suspension.
  • 🌊 Body rocking after overcoming speed bumps or potholes (more than 2-3 vibrations).
  • 💧 Oil leaks on the shock absorber body - evidence of loss of tightness.
  • 🚗 Uneven rear tire wear (especially along the inner or outer edge).
  • 🔊 Knocks or squeaks in the rear suspension area when driving over uneven surfaces.

On Almera Classic rear shock absorbers often “die” before the front ones due to the characteristics of load distribution (especially if the car often carries passengers or cargo). You can check their condition yourself: press firmly on the rear bumper and release. If the body oscillates more than 1-2 times, the shock absorbers are not doing their job.

⚠️ Attention: On models with a mileage of more than 150 thousand km, it is recommended to check the condition of the shock absorbers simultaneously support cups, anthers And fenders. Their wear accelerates the failure of new racks.

Which shock absorbers should I choose for Nissan Almera Classic?

There are three types of parts on the market: oil, gas-oil And gas. For Almera Classic (especially in Russian conditions) the optimal choice is gas-oil. They combine the softness of oil ones and the reliability of gas ones, withstand temperature changes better and rarely “break through” on uneven surfaces.

Original shock absorbers from Nissan have an article number 54300-4M000 (right) and 54301-4M000 (left), but they are often overpriced. Alternatives from trusted brands:

Brand Article (right/left) Type Average price, rub. Features
Kayaba (KYB) 343309 / 343310 Gas-oil 2 800–3 500 Stiffer than the original, but more durable. Suitable for aggressive riding.
Monroe G4502 / G4503 Gas-oil 3 200–4 000 Soft, comfortable for the city. Often installed on a conveyor.
Sachs 315 383 / 315 384 Gas 4 500–5 200 Sporty rigidity, minimal roll in corners.
Boge 23-0546 / 23-0547 Oily 2 500–3 000 A budget option for a quiet ride. Doesn't like frost.

When choosing, pay attention to rod length And body diameter - they must match the original. On Almera Classic Counterfeit brands are common KYB And Monroe, so buy only from authorized dealers or trusted sellers. Also check the contents: the box should contain boot, bumper And fastening nut.

Tools and materials for replacement

To work, you will need a standard set of tools, but there are also specific devices. Without them, the process may be delayed or result in damage to parts. Here's the full list:

  • 🔧 Jack And supports (or a lift) - be sure to fix the machine on a flat surface!
  • 🔨 Head set (10, 12, 14, 17, 19 mm) and extension cord for working in hard-to-reach places.
  • 🔩 21 mm socket wrench — to unscrew the shock absorber rod nut (often sticks).
  • 🛠️ Spring ties - if you plan to remove the springs (on Almera Classic you can do without them, but for beginners it’s better to play it safe).
  • 🧲 Magnetic pen or tweezers - for removing small parts (for example, washers).
  • 🧴 WD-40 or similar - for processing rusted connections.
  • 🔧 Torque wrench — for correct tightening of the nuts (tightening torque, see below).

Also prepare new nuts and bolts (especially if the old ones are rusty) and rubber bushings (article 54520-4M000). On Almera Classic The bushings of the lower shock absorber mount often wear out - replacing them will extend the life of the new strut.

💡

Before starting work, take photographs of the location of all bolts and nuts on the phone. This will help avoid confusion during assembly, especially if this is your first time replacing shock absorbers.

Step-by-step instructions for replacing rear shock absorbers

Replacement process Nissan Almera Classic takes about 2-3 hours (if there is no serious corrosion). It is better to carry out work in a garage or on an overpass. Follow this algorithm:

  1. Preparing the car. Jack up the rear of the car and place supports under the sills. Remove the rear wheels. Be sure to block the front wheels with chocks!

  2. Removing the old shock absorber.

    • Unscrew bottom bolt attaching the shock absorber to the lever (17 mm head).
    • Remove in the cabin plastic plug above the upper support mount (under the rear seat).
    • Unscrew rod nut (21 mm wrench), holding the rod from turning with a 6 mm hexagon.
    • Pull the shock absorber down through the wheel arch.

  3. Installing a new shock absorber.

    • Transfer spring And support cup from the old shock absorber to a new one (if you didn’t buy a kit).
    • Reinstall the shock absorber starting from top mount.
    • Tighten the stem nut previously (make the final tightening after lowering the machine!).
    • Attach the bottom bolt and tighten it to torque 80–100 Nm.

  • Checking and fine-tuning. Make sure all nuts are tight and there is no play. Lower the car and push the rear firmly a few times to help the shock absorbers settle.

    • ☑️ Checklist before assembly

    Done: 0 / 4

    On Almera Classic there is often a problem with stuck rod nut. If it does not unscrew, try the following methods:

    • Process WD-40 and wait 10–15 minutes.
    • Use impact wrench or hammer with chisel (carefully!).
    • Heat the nut construction hairdryer (do not overheat - the rubber of the support may be damaged).
    ⚠️ Attention: Do not use grinder for cutting the rod nut! This can damage the threads on the rod and the new shock absorber will have to be replaced. If the nut does not budge, contact service.

    Typical replacement mistakes and how to avoid them

    Even experienced car owners sometimes make mistakes that lead to quick shock absorber failure or deterioration in handling. Here are the most common mistakes on Nissan Almera Classic:

    • 🔧 Incorrect tightening of nuts. Shock absorber rod nut cannot be tightened by weight - only after the car is on wheels! Otherwise, the spring will be skewed and the shock absorber will quickly wear out.
    • 🔄 Confused right/left shock absorbers. On Almera Classic they are visually similar, but have different rigidity. The right one is usually marked with the letter R, left - L.
    • 🚫 Ignoring bushings. Old rubber bushings on the lower mount often crack. Replacing them costs a penny, but extends the life of the shock absorber.
    • 🔩 Using old nuts/bolts. Rusted or deformed fasteners may break when tightened. Always take new ones!
    • 🔊 No pumping of shock absorbers. Before installing a new gas-oil shock absorber, you need to pump up (compress/uncompress 5-6 times), otherwise it will quickly fail.

    Another common mistake is incorrect installation of the bump stop. It must be put on the stem before installing the shock absorber in the back! If you forget to do this, you will have to disassemble everything again.

    What happens if you don't change shock absorbers on time?

    Worn shock absorbers increase braking distance by 20–30%, reduce traction when cornering and increase the risk of skidding. In addition, other suspension elements suffer: wheel bearings, silent blocks and ball joints. In critical cases, the shock absorber rod may rupture, leading to loss of control.

    Bleeding shock absorbers before installation

    Gas-oil and gas shock absorbers before installation definitely need to upgrade. This removes air from the working chamber and prevents premature wear. On Almera Classic the procedure looks like this:

    1. Keep the shock absorber vertically (stock up).
    2. Squeeze it smoothly until it stops and hold it in this position for 2-3 seconds.
    3. Slowly return to starting position.
    4. Repeat 5-6 times.
    5. After pumping, the shock absorber should move smoothly, without jerking.

    If the shock absorber “jams” or moves with force, it is defective. Don't install it! Also check if oil leaks on the case - this is a sign of a manufacturing defect.

    💡

    Bleeding shock absorbers is a mandatory step! Without it, a new shock absorber may fail after 10–15 thousand km.

    Wheel alignment adjustment after replacement

    On Nissan Almera Classic replacing rear shock absorbers does not require mandatory wheel alignment adjustment, since they do not affect the wheel alignment angles. However, there are nuances:

    • If you were filming suspension arms or silent blocks, adjustment required.
    • After replacing shock absorbers, check axis longitudinal tilt (caster). On Almera Classic it must be within -1° ± 30'.
    • If you notice that the car is “pulling” to the side, do body geometry check — the symmetry of the suspension may be broken.

    For an accurate diagnosis, visit a wheel alignment stand. The cost of checking is about 500–800 rubles, but it is cheaper than repairing the suspension due to incorrect angles.

    FAQ: Frequently asked questions about replacing rear 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 “live”, it is already worn out, and the difference in stiffness will lead to uneven tire wear and deterioration in controllability. Swap in pairs!

    How long do shock absorbers last on Almera Classic?

    The period depends on the operating conditions:

    • City riding: 80–100 thousand km.
    • Aggressive driving/bad roads: 50–70 thousand km.
    • Gas-oil shock absorbers (KYB, Monroe) last longer than oil ones by 20–30%.

    Do the springs and shock absorbers need to be replaced?

    If the springs didn't sag (the distance between the turns is the same) and there are no cracks - no need to change. However, on cars older than 10 years, the springs often lose their elasticity, which accelerates the wear of new shock absorbers.

    What to do if after replacement the car has become harder?

    This is normal for new shock absorbers (especially gas-oil ones). They will “grind” through 200–300 km. If the hardness has not decreased, check:

    • Correct installation fenders And anthers.
    • Condition support bearings (on Almera Classic they often wear out at the same time as the shock absorbers).

    Is it possible to drive with faulty rear shock absorbers?

    Technically yes, but it's dangerous:

    • The braking distance increases by 20–30%.
    • Increased risk aquaplaning on a wet road.
    • Wear accelerates tires, wheel bearings And silent blocks.

    At the first sign of trouble, replace the shock absorbers!
