Nissan Almera Classic (known in some markets as Nissan Sunny or Samsung SM3) is one of the most popular sedans in the budget segment, but even it has its weaknesses. One of them is rear strut supports, which wear out over time, leading to knocks, vibrations and poor handling. In this article we will look at how to diagnose a malfunction, which supports to choose for replacement, and why original parts from Nissan with article number 54510-4M000 often counterfeited - and how to check it.

Rear pillars in Almera Classic (body B10, 2006–2012) work in harsh conditions: constant loads from the weight of luggage, rough roads and metal corrosion. The shock absorber mounts (or “cushions”) dampen vibrations, but over time the rubber cracks and the metal elements rust. If you ignore the problem, the consequences can be serious - from damping fluid leakage to destruction of fastenings and loss of control of the car at high speed.

Symptoms of a faulty rear strut support

The first symptoms of bearing wear are often confused with shock absorber or suspension problems. However, there are key signs that directly indicate support bearings or rubber dampers:

  • 🔊 Knocking or squeaking in the rear of the body when driving over bumps (even at low speed). The sound often radiates into the trunk or back seat.
  • 🚗 Pulling the car to the side when braking or accelerating, especially if the rear wheels are at different angles.
  • 🔄 Body "bouncing" after hitting a bump - a sign that the support does not firmly fix the rack.
  • 💧 Visible cracks or tears on the rubber part of the support (can be seen by removing the protective cap in the trunk).

If at least two of these symptoms occur simultaneously, the probability of bearing wear is 80–90%. For accurate diagnosis it is enough swing the car by the rear bumper — if a dull knock is heard and the body continues to sway for more than 1–2 seconds, the supports require replacement.

⚠️ Attention: Do not confuse the knocking of supports with play in the silent blocks of the rear beam! To eliminate the second problem, check the beam on the lift - if there is play, it will be visible when the wheel is rocked manually.
📊 How often do you check the condition of your car's suspension?
  • Every 10,000 km
  • Once a year
  • Only when knocking occurs
  • Never checked

Which rear strut mounts are suitable for Nissan Almera Classic

There are three types of supports on the market for Almera Classic (B10):

  1. Original (Nissan 54510-4M000 or 54510-4M001) - the most reliable, but expensive (from 2,500 rubles per piece). Suitable for all modifications, including 1.6 And 1.4.
  2. Premium analogues from KYB (SM5048), Monroe or Sachs — high-quality rubber and metal, price 1,800–2,200 rubles.
  3. Budget analogues from Febi, TRW or Sidem - cheaper (1,200–1,500 rubles), but the resource is 30–40% lower.

Important: supports for Almera Classic And Nissan Sunny (Korean assembly) interchangeable, but there are nuances with fastenings. For example, on some versions SM3 supports are used with reinforced flange - their article number 54510-4M010.

Brand Article Price (for 1 piece), rub. Features
Nissan (original) 54510-4M000 2 500–3 000 Rubber with graphite impregnation, metal with anti-corrosion coating
KYB SM5048 1 900–2 200 Reinforced support bearing, suitable for harsh conditions
Monroe 904546 1 800–2 000 Soft rubber, transmits less vibration to the body
Febi 22610 1 200–1 400 Budget option, resource ~50,000 km

When choosing, pay attention to country of origin: original supports Nissan for Almera Classic were issued in Japan (labeling Made in Japan), and analogues - in Korea or Taiwan. Counterfeits often come from China without markings - they are given away by the low quality of the rubber (smells of chemicals) and the lack of a protective film on the metal.

💡

Before buying, check the support for weight - the original weighs ~1.2 kg, and fakes are often 200-300 grams lighter due to thin metal.

Step-by-step instructions for replacing the rear strut support

You can do the replacement yourself if you have one. jack, spring ties and socket set. Working time: 2–3 hours for both racks. Important: replace supports in pairs, even if the second one is “still normal”, this will prevent the suspension from becoming unbalanced.

Remove the trunk trim and gain access to the upper nuts of the struts|Jack up the rear and remove the wheel|Loosen the lower mount of the strut (17 mm nut)|Install the spring ties before disassembling|Prepare new mounts and thread lubricant-->

Step 1. Dismantling the old support

  1. Remove the plastic trim in the trunk (it is secured with 4 clips). Underneath you will see three 14 mm nuts, with which the support is attached to the body.
  2. Loosen the nuts (do not remove completely!), then jack up the car and remove the wheel.
  3. Unscrew the lower fastening of the rack to the beam (nut on 17 mm and bolt on 19 mm). Use WD-40 if the threads are stuck.
  4. Carefully remove the stand from its seat and remove it along with the spring.

Step 2. Disassembling the rack and replacing the support

Here you will need spring ties (rent from a car service center if you don’t have your own). Algorithm:

  1. Place the ties on the spring and compress it until a gap appears between the coils.
  2. Unscrew the central nut of the shock absorber rod (the wrench is on 22 mm, hold the rod with a hexagon on 6 mm).
  3. Remove the old support, clean the seat from dirt and rust.
  4. Install the new support, observing the orientation (the arrow on the body should point up).
  5. Tighten the stem nut firmly 40–50 Nm (do not overtighten!).

Step 3. Assembly and testing

After installing the new support:

  • Smoothly release the spring ties.
  • Place the stand in place, tighten the lower fastening (tightening torque - 80–100 Nm).
  • Tighten the nuts of the upper support mounting to the body (25–30 Nm).
  • Pump the rack 3-4 times (press the bumper and release sharply) until the support “settles”.
⚠️ Attention: If after replacement there is squeaking sound when turning the steering wheelMost likely, you have overtightened the shock absorber rod nut. Loosen it 1/4 turn and check again.
What to do if the spring is not compressed by the ties?

If the spring does not give in even with the maximum tightening force, try the following methods:

1. Treat the spring coils with WD-40 - sometimes rust interferes with compression.

2. Use hydraulic couplers (they are more powerful than mechanical ones).

3. As a last resort, contact a service center - they have special devices for “stubborn” springs.

NEVER try to compress a spring without ties (for example, with a rope or cable) - this is dangerous!

Common mistakes when replacing supports and how to avoid them

Even experienced car owners make mistakes that lead to knock again or rapid wear of new supports. Here are the most common:

  • 🔧 Reusing old nuts and bolts — the threads on them are often worn out, which leads to backlash. Always use new fasteners.
  • 🔩 Incorrect tightening — if you overtighten the rod nut, the support bearing will quickly fail. The tightening torque should be 40–50 Nm.
  • 🚫 Ignoring shock absorber check — if the rack leaks or does not hold pressure, the new support will last a maximum of 10–15 thousand km.
  • 🔄 Replacing only one support - this upsets the balance of the suspension and accelerates wear of the second strut.

Another typical problem is incompatibility of supports with shock absorbers. For example, if you installed racks KYB Excel-G, and the supports were taken from Febi, the rubber may not withstand the load due to different hardness. Always check directory compatibility:

1. The condition of the rubber bushings in the lower rack mount.

2. Play in the silent blocks of the rear beam.

3. Spring integrity (cracks or corrosion).-->

Support life: when to change and how to extend the service life

Average service life of rear strut supports Nissan Almera Classic — 80,000–120,000 km, but it greatly depends on the operating conditions:

  • 🛣️ Bad roads — potholes and speed bumps reduce the service life to 50–60 thousand km.
  • 🌧️ Humid climate — corrosion of metal parts accelerates wear of rubber.
  • ⚖️ Vehicle overload — if you often carry heavy loads, the supports wear out 30% faster.

To extend the life of supports:

  1. Every 10,000 km check their condition (a visual inspection through the hatch in the trunk is sufficient).
  2. After washing a car in winter blow with compressed air support seats - this will prevent moisture accumulation.
  3. Use silicone grease for rubber parts (eg LIQUI MOLY Silicon-Fett), but do not overdo it - excess attracts dirt.

If you do a lot of off-road driving, consider installing supports with reinforced bearing (For example, KYB SM5048). They are 20–30% more expensive, but can withstand loads 1.5 times higher than standard ones.

Alternative solutions: repair vs replacement

Some car owners are trying repair supports instead of replacement. This is possible, but only in two cases:

  1. Cracks in rubber - can be sealed with a special sealant for rubber (for example, Loctite 406), but this is a temporary solution (will last ~10,000 km).
  2. Support bearing wear — it can be replaced separately (article no. 54510-4M005), if the support body is intact.

However repairs are justified only in 20% of cases:

  • ✅ If the support is rare and is not on sale (relevant for Almera Classic early releases).
  • ✅ If the budget is very limited, and the car is used sporadically.
  • ❌ If the rubber has delaminated or the metal has rusted, repairs are useless.

The cost of a new bearing is ~500 rubles, but the work to replace it will cost 1,500–2,000 rub. (you need to disassemble the stand). Most often it is cheaper to buy a new support.

💡

Repairing the support makes sense only as temporary measure. After 5–10 thousand km the problem will return, and the risk of the support coming off while driving will increase 3 times.

FAQ: Frequently asked questions about rear strut supports

Is it possible to drive with knocking supports? What are the consequences?

Short-term (1-2 weeks) - yes, but the risks are serious:

  • Accelerated wear of shock absorbers (up to 50% reduction in service life).
  • Destruction of support seats in the body (welding repairs will be required).
  • Loss of controllability at speeds above 80 km/h (the car may “yaw”).

If the support falls apart while driving, the strut breaks through the body - repairs will cost 15,000–20,000 rub.

How to distinguish an original support from a fake?

Original (Nissan 54510-4M000) has:

  • Logo Nissan and labeling Made in Japan on the body.
  • The rubber is black with a matte tint (for fakes it is shiny).
  • Metal elements with zinc coating (do not rust when scratched).
  • Comes with protective cap with logo.

Counterfeits are often sold without packaging or in plastic bags.

Is it necessary to do a wheel alignment after replacing the bearings?

No, replacement of supports no effect on the wheel alignment angles, since they are not adjustable on the rear axle Almera Classic. However, if you notice that the car is “pulling” to the side, check:

  • Tire pressure (must be the same).
  • Condition of the rear brakes (a jammed caliper can drag the car).
  • Wheel balancing.
Can the supports be replaced without spring ties?

Theoretically yes, but this extremely dangerous. The spring is under enormous tension - if it comes off, it can cause serious injury. Alternative methods:

  • Use cable ties (less reliable, but better than nothing).
  • Contact the service center - they have pneumatic ties.
  • Remove the stand assembly and take it to a workshop for disassembly.

Never try to hold the spring with your hands or rope!

Which supports are better - original or KYB?

Comparison:

Criterion Nissan (original) KYB (SM5048)
Resource 100–120 thousand km 90–110 thousand km
Price 2,500–3,000 rub. 1,900–2,200 rub.
Hardness Softer, better for comfort Stiffer, better for sporty riding
Bearing reliability Standard Reinforced (withstands heavy loads)

Conclusion: If you drive carefully on good roads, take the original. If you often load your car or drive off-road - KYB preferable.
