Front strut <em>Nissan Almera Classic</em>: how to diagnose, select and replace

Nissan Almera Classic (also known as Nissan Sunny B10 in some markets) is one of the most popular sedans in the budget segment, which is still actively used due to its simplicity of design and availability of spare parts. However, the front suspension, namely front struts, is one of the most vulnerable points of this car. Wear on shock absorbers and support bearings appears after 80–100 thousand km, and on Russian roads this period is reduced to 60–70 thousand km.

In this article we will analyze all aspects of working with the front struts Almera Classic: from fault diagnosis to self-replacement. You will learn which racks are best to choose (original, analogues or sports versions), how to check their condition without a lift, and which hidden problems may arise during replacement - for example, corrosion of fasteners or wear of silent blocks of levers, which are often overlooked.

The material will be useful to both beginners and experienced car owners: there are no template tips here, only specific information on Almera Classic taking into account its design features (for example, compatibility of racks with Nissan Sunny And Samsung SM3).

Front pillar design Nissan Almera Classic: what's inside?

Front suspension Almera Classic built according to the classical scheme MacPherson - this means that the stand performs two functions: shock absorber (vibration damping) and load-bearing element (supports body weight). Unlike a multi-link suspension, there is no separate upper arm - its role is played by the strut itself, along with support bearing.

Main components of the front strut Almera Classic:

• 🔧 Shock absorber — hydraulic or gas-oil (depending on modification). The original racks use ATF oil with additives for stable operation at low temperatures.
• 🌀 Spring - twisted, with variable pitch for progressive stiffness. On Almera Classic springs were installed 5–6 turns (depending on the year of manufacture).
• 🔄 Support bearing — allows the rack to rotate when the steering wheel is turned. B Almera Classic bearing is used ball type (not roller!), which is important when choosing a spare part.
• 🛠️ Compression buffer - a rubber or polyurethane damper that prevents metal from hitting metal when the rack is fully compressed.
• 🔩 Fasteners — two bolts at the bottom (to the steering knuckle) and three nuts at the top (to the body cup). On cars older than 2010, the upper mounting studs often rust - this requires additional treatment with WD-40 or replacement of the studs.

Feature Almera Classic: left and right side racks interchangeable (symmetrical), but when replacing it is recommended to install them in pairs to avoid imbalance of the suspension. It is also worth considering that on vehicles with ABS The wheel speed sensor is attached to the rack - it can be easily damaged when dismantling.

Why racks Almera Classic do they break down faster than other cars?

The main reason is a design feature: the springs here are shorter than those of competitors (for example, Toyota Corolla E12), due to which the load on the shock absorber is distributed unevenly. In addition, the original struts use softer oil, which quickly loses its properties with frequent trips on rough roads. Another factor is poor anti-corrosion treatment of fasteners, which leads to “sticking” of nuts and bolts.

Signs of faulty front struts: how to diagnose without a service station

Worn out struts Nissan Almera Classic manifest themselves differently, but there are 5 Key Symptomsthat cannot be ignored:

1. Deterioration in handling — the car “floats” on the road, especially at speeds above 80 km/h. When turning the steering wheel sharply you feel delayed reaction.
2. Increased braking distance — the struts affect the downforce of the wheels. If the car nods when braking, this is a sign loss of damping properties shock absorber
3. Uneven tire wear — “bald patches” appear on the inside or outside of the tread. This is due to a violation of the wheel alignment due to a sagging strut.
4. Knocks when driving over bumps - most often caused by wear and tear support bearing or compression buffer. On Almera Classic The knock may come from the steering wheel.
5. Oil leaks on the rack — if the shock absorber “sweats” or there are obvious traces of oil, it’s time to change it. Original racks Nissan rarely leak, but inexpensive analogues (for example, Fenox or Patron) can start leaking after 20 thousand km.

For quick check of racks Almera Classic without lift:

1. Press the car fender and release it quickly. If the body does more than 1–2 fluctuations, the stand is faulty.
2. Rock the car up and down by the front fender. Play or creaking will indicate wear of the support bearing.
3. Check the springs for cracks or corrosion - this is critical for Almera Classic, since rust weakens the metal.

Which racks to choose for Nissan Almera Classic: original vs analogues

Selection of racks for Almera Classic Depends on budget and driving style. Original racks Nissan (article 54300-9M000 for the left/right side) are expensive (from 8-10 thousand rubles per piece), but guarantee factory specifications. However, there are worthy analogues on the market, which sometimes exceed the original in terms of resource.

Comparison table of popular options:

Manufacturer	Article	Type	Average price (pieces)	Resource (thousand km)	Features
Nissan (original)	54300-9M000	Oily	8 000–10 000 ₽	80–100	Soft operation, but sensitive to low temperatures
Kayaba (KYB)	334302	Gas-oil	5 500–6 500 ₽	100–120	Stiffer than the original, better for aggressive driving
Monroe	37169	Oily	4 500–5 500 ₽	70–90	Budget analogue, close to the original in terms of comfort
Bilstein	19-135437	Gas	7 000–8 500 ₽	120+	Sporty stiffness, suitable for tuning
Fenox	A23020C3	Oily	2 500–3 500 ₽	40–60	Low resource, often leaks

Recommendations for selection:

• 🚗 For city driving: Monroe or original Nissan — optimal balance of comfort and price.
• 🏁 For a sporty style: Bilstein or Kayaba — better handling, but tougher.
• 💰 Budget option: Fenox or Patron, but be prepared to replace it after 30–40 thousand km.

Important: When purchasing racks, check compatibility with the year of manufacture Almera Classic. For example, model racks 2006–2008 may not fit cars 2012–2013 due to changes in the support bearing mounting.

Step-by-step replacement of the front strut Nissan Almera Classic with your own hands

Replacing the rack with Almera Classic - a task of medium difficulty, but requires care. Main difficulties: stuck bolts (especially the lower mount to the steering knuckle) and high tension spring (risk of injury!). Below are step-by-step instructions taking into account the nuances of this model.

Required tools:

• 🔧 Set of heads (10, 12, 14, 17, 19 mm) and collars.
• 🔨 Hammer and chisel (for unscrewing stuck nuts).
• 🔩 Clamps for compressing springs (required!).
• 🛠️ WD-40 or similar penetrating lubricant.
• 🔧 Torque wrench (for tightening with the correct torque).

Work order:

1. Preparation:
   • Secure the car on a flat surface, place supports under the rear wheels.
   • Loosen the wheel nuts, but do not remove it completely.
   • Apply WD-40 to all threaded connections (especially the lower strut bolt).
2. Removing the old rack:
   • Jack up the car and remove the wheel.
   • Unscrew the two bolts securing the rack to steering knuckle (19 mm wrench). If the bolts are stuck, use a chisel and hammer.
   • Unscrew the three nuts of the upper pillar mounting in the engine compartment (12 mm wrench).
   • Remove the strut assembly with the spring.
3. Disassembly and replacement:
   • Place the stand in a vice and compress the spring with clamps.
   • Unscrew the shock absorber rod nut (17 mm wrench), holding the rod with a hexagon.
   • Remove the support bearing, spring and compression buffer. Check status spring cups - on Almera Classic it often rusts.
   • Transfer the parts to the new rack in reverse order.
4. Installation and tightening:
   • Reinstall the stand and tighten the bottom bolts to torque. 80–100 Nm.
   • Tighten the top nuts to torque 20–25 Nm (do not overtighten!).
   • After replacement, be sure to do wheel alignment - even if you didn't touch the levers.

⚠️ Attention: on Almera Classic after 2010 they often break down top mounting studs racks when unscrewing. If the stud has turned, it will have to be drilled out and a new thread cut. To avoid this, before unscrewing the nut, put two wrenches on the stud and hold it from turning.

Common mistakes when replacing racks and how to avoid them

Even experienced craftsmen make mistakes when working with suspension Almera Classic. Here are the most common:

1. Incorrect spring compression:

   If the clamps are installed asymmetrically, the spring may “shoot” during disassembly. On Almera Classic the spring has asymmetrical winding - squeeze it evenly on both sides.

2. Ignoring the support bearing:

   Many people change only the strut, leaving the old bearing. This leads to knocking sound when turning the steering wheel already after 10–15 thousand km. Supporter on Almera Classic It is inexpensive (about 1,000 ₽), but replacing it requires care.

3. Retightening the top nuts:

   If you tighten the nuts securing the strut to the body to a torque greater than 25 Nm, the support bearing will begin to “creak”. Use a torque wrench!

4. They forget about the compression buffer:

   On Almera Classic the buffer often “sticks” to the shock absorber rod. If it is not replaced, a metallic sound will be heard when the strut is fully compressed.

5. They don't check the silent blocks of the levers:

   Worn front arm silent blocks (54503-9M000) accelerate the wear of new struts. Check their play before installing the rack.

⚠️ Attention: if after replacing the racks Almera Classic appeared squeal when turning steering wheelMost likely, you have overtightened the shock absorber rod nut or installed the support bearing incorrectly. You'll have to disassemble the stand again.

Is it worth replacing the racks in pairs? Arguments for and against

The debate about whether it is necessary to change racks in pairs continues among owners Almera Classic. Let's look at the arguments:

Reasons to change in pairs:

• 🔄 Uniform behavior of the car: Even if one strut is fine, the difference in rigidity will cause the car to pull to the side.
• 🛠️ Save time: If one rack is worn out, the second one will soon fail. It's better to do everything at once.
• 💰 Discounts on work: Many service stations give a discount when replacing a pair of racks.

When to replace one rack:

• 🚗 If the second rack is almost new (less than 20 thousand km).
• 💥 If the malfunction is caused by mechanical damage (for example, an impact during an accident).
• 🔧If you are using repair kit (replacing only the shock absorber, not the entire strut assembly).

On Almera Classic there is a nuance: if one strut is leaking and the second is dry, but has a mileage of more than 80 thousand km, it is better to replace both. The point is that the oil in the shock absorbers is getting old even without visible leaks, and after 10–15 thousand km the second strut will also fail.

Caring for racks: how to extend their service life

Rack life Nissan Almera Classic depends not only on the quality of spare parts, but also on operating conditions. Here 5 rulesthat will help extend the life of the suspension:

1. Avoid sharp impacts:

   When driving through speed bumps or potholes, slow down in advance. A sharp impact can damage the shock absorber seals.

2. Wash your pendant in winter:

   Salt and reagents corrode the anthers of the racks. Once a month, wash the wheel arches and struts with water under pressure.

3. Check the anthers:

   On Almera Classic the anthers often crack. If the boot is torn, dirt will get into the shock absorber and it will fail within 5-10 thousand km.

4. Monitor your tire pressure:

   Underinflated tires increase the load on the racks. Optimal pressure for Almera Classic: 2.0–2.2 bar.

5. Don't overload the car:

   Maximum front axle load - 850 kg. Exceeding the weight by 20% reduces the service life of the racks by 2 times.

⚠️ Attention: If you often drive on dirt roads, install protective covers on racks (for example, from KYB). They prevent sand from getting into the shock absorber seals.

FAQ: Frequently asked questions about racks Nissan Almera Classic

Is it possible to drive if the strut is leaking but not knocking?

A shock absorber leak means that oil comes out of the working chamber and the strut loses its damping properties. Even if there is no knock, handling deteriorates and braking distance increases. It is recommended to replace the stand within 1-2 weeks.

Which struts fit from other cars to Almera Classic?

On Almera Classic (B10) suitable racks from:

• Nissan Sunny B10 (complete analogue);
• Samsung SM3 (Korean version Almera Classic);
• Renault Scala (first generation, but the top mount needs improvement).

Racks from Nissan Almera N16 don't fit - another design.

Do I need to do a wheel alignment after replacing the struts?

Required, even if you didn't touch the levers. New struts can change the suspension height, which will affect the camber and toe angles. On Almera Classic disruption of the camber leads to uneven tire wear already after 5 thousand km.

What happens if you don't change the support bearing?

A worn out support leads to:

• Knock when turning the steering wheel;
• Vibrations in the steering wheel at speeds above 60 km/h;
• Accelerated wear of the struts (due to spring misalignment).

On Almera Classic A support bearing costs about 1,000 rubles - replacing it is cheaper than repairing the consequences.

Is it possible to restore the racks? Almera Classic?

Theoretically yes: some workshops offer bulkhead struts (oil change, seals, valves). However for Almera Classic this is rarely justified:

• The cost of restoration is 3,000–4,000 RUR per rack (it’s cheaper to buy a new one Monroe);
• The quality of refurbished racks is unpredictable;
• There is usually no guarantee for such work.

Exception - sports racks (For example, KYB or Bilstein), which can be sorted out using repair kits.
