Support bearings Nissan Almera Classic: diagnostics, selection and replacement

Nissan Almera Classic (also known as N16 or B10 in some markets) is a reliable sedan, but even it has its weaknesses. One of them is **support bearings of the front struts**, which wear out after 80-120 thousand kilometers. Their malfunction is manifested by knocking, vibration on the steering wheel and deterioration in controllability. In this article, we will look at how to recognize the problem in time, what spare parts to choose and how to replace the bearings yourself - with nuances that are not written about in standard manuals.

Feature Almera Classic is that the journal bearings here are integrated into the **strut journal bearing** (often referred to as the “post”). This simplifies the design, but complicates diagnostics: knocking can be masked as wear of racks or silent blocks. We have collected symptoms that accurately indicate the bearing, and not neighboring components, and added unique testing techniques without disassembling the suspension.

Signs of faulty support bearings on a Nissan Almera Classic

The first signal is a **knock in the front suspension** when driving over bumps at low speed (for example, speed bumps). Unlike worn struts, which “rattle” on large holes, support bearings emit sharp metallic clicks. Important nuance: on Almera Classic The knock often comes from the steering wheel and not from the wheel arches.

Other symptoms:

• 🔧 Creaking sound when turning the steering wheel in place - indicates destruction of the bearing cage.
• 🚗 Steering wheel vibration at a speed of 60–80 km/h, even on a flat road.
• 🔄 Deterioration of self-centering steering wheel after turns (the car “floats” in a straight line).
• 💥 Crunching sound when rocking the car behind the wing - a sign of critical wear.

On Almera Classic with a mileage of over 100 thousand km, the knocking of the support bearings is often confused with wear ball joints or steering tips. To eliminate the error, use the test: press the brake when driving over uneven surfaces. If the knocking noise disappears, the support bearings are to blame (when braking, the load is redistributed and the play in the bearing temporarily disappears).

⚠️ Attention: If you ignore the knocking of the bearings, this will lead to the destruction of the bearing cup and damage to the shock absorber rod. On Almera Classic this is fraught with oil leakage from the rack and the need to replace the entire assembly (price - from 8,000 ₽ per side).

Which support bearings are suitable for Nissan Almera Classic (N16)

On Almera Classic (2006–2012) two types of support bearings were installed depending on the year of manufacture and configuration:

• 🔹 Before 2009: the bearing is integrated into the strut support (original article number - 54303-4M000). Substitutes: KYB SM5336, SASIC 2005017.
• 🔹 After 2009: separate bearing (article - 54303-4M001). Analogues: SKF VKBA 3603, FEBEST BPC-016.

Important: on machines with ABS And ESP (configurations Comfort And Luxury) the supports are distinguished by reinforced fastenings. When purchasing, check for the tag «ABS» on the packaging. Counterfeits often do not have this marking, but are externally identical to the original.

Brand	Article	Price (for 1 piece), ₽	Features
Nissan (original)	54303-4M001	3 200–4 500	Complete with dust cover and fasteners
KYB	SM5336	2 100–2 800	Reinforced bearing, suitable for harsh conditions
SKF	VKBA 3603	1 800–2 300	Best price/quality ratio
FEBEST	BPC-016	1 200–1 600	Budget option, resource ~50 thousand km

Tip: When replacing support bearings with Almera Classic be sure to check the condition of the **compression progress buffer** (article no. 54320-4M000). It often cracks and causes knocking noises that are mistakenly attributed to bearings.

Diagnostics of support bearings without disassembly

To confirm bearing wear without removing struts, use these methods:

1. Sway test: open the hood, place your hand on the top of the pillar and sharply rock the car up and down. Play or clicking is a sign of wear.
2. Checking on turns: With the car parked, turn the steering wheel left and right. Squeaking or resistance - the bearing requires replacement.
3. Visual inspection: Shine a flashlight through the cracks in the support - if rusty deposits or cracks in the rubber are visible, the part needs to be replaced.

On Almera Classic There is a specific symptom: when driving on a gravel road, the knocking of the support supports is synchronized with the rotation of the wheels (the frequency increases with increasing speed). This helps distinguish them from knocking stabilizer or leverage.

What happens if you drive with a broken support bearing?

On Almera Classic, a worn bearing leads to:

- uneven wear of tires (especially the inner edge);

- increased braking distance due to play in the suspension;

- the risk of the shock absorber rod “shooting out” during a strong impact (for example, on a bump).

Step-by-step instructions for replacing support bearings

To work you will need:

• 🔧 Set of heads (10, 12, 14, 17 mm) and collars.
• 🔧 Special puller for strut springs (required!).
• 🔧 Torque wrench (nut tightening torque - 50–60 Nm).
• 🔧 WD-40 or a similar composition for unscrewing stuck nuts.

Procedure:

1. Remove the wheel and unscrew the nut securing the strut to the steering knuckle (size - 17 mm). Do not disconnect the brake hose!
2. Unscrew the three nuts securing the support to the body (under the hood, size - 12 mm).
3. Remove the stand assembly. Attention: the spring is under high tension - use zip ties!
4. Compress the spring with zip ties, then unscrew the shock absorber rod nut (size - 14 mm).
5. Remove the old support with bearing and install the new one. Apply before assembly lithol to the bearing seat.

- Check the integrity of the strut boot

- Make sure that the spring is installed with the “bottom coil down”

- Tighten the shock absorber rod nut to a torque of 50 Nm

- Bleed the rack (compress/uncompress 5–6 times to distribute the oil) -->

Key point: on Almera Classic after replacing the bearings, be sure to check and, if necessary, adjust the **wheel alignment**. Even a small play in the bearing could throw off the settings, and after repair the angles often “go” into the minus.

⚠️ Attention: If during disassembly you find that the rubber part of the support has delaminated or cracked, replace the support assembly (part number 54300-4M000). Installing a new bearing in a worn support will lead to its rapid destruction.

Common replacement mistakes and how to avoid them

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

• ❌ Using a percussion instrument for unscrewing nuts. This deforms the shock absorber rod. Correct: 1-2 hours before work, treat the threads WD-40 and unscrew by hand.
• ❌ Incorrect spring installation. If you mix up the top/bottom, the coils will rub against the support cup, causing a squeak. On springs Almera Classic the lower turn is thinner than the upper one.
• ❌ Ignoring progress buffer check. A destroyed buffer gives the same symptoms as a worn bearing. Always inspect it for cracks.

Another typical problem is **tightening the rod nut**. On Almera Classic the tightening torque must be strictly 50–60 Nm. Exceeding will lead to difficult movement of the shock absorber and accelerated wear of the seals.

Is it worth changing the support bearings yourself?

Replacing support supports with Almera Classic refers to work of medium complexity. If you have experience in suspension repair and a special tool (spring ties), you can do it in 3–4 hours. However, there are nuances that make the task non-trivial:

• ⚙️ Stuck nuts - on machines older than 10 years, threaded connections often rust. It is difficult to unscrew them without a gas wrench or wrench.
• ⚙️ Risk of spring damage - if the tie is not tightened correctly, it can “shoot” and cause injury.
• ⚙️ The need to adjust the camber — without this, new bearings will last 2 times less.

The cost of work in the service is from 2,500 to 4,000 rubles per side (depending on the region). If you are not confident in your abilities, it is better to entrust the repair to professionals. However, if you have the tools and patience, replacing it yourself will save up to 50% of your budget.

Tip: If you decide to do the work yourself, take pictures of the location of all the parts before disassembling. On Almera Classic There are racks with different support fastenings (3 or 4 bolts), and it is easy to confuse them.

FAQ: Frequently asked questions about support bearings Nissan Almera Classic

Is it possible to drive with knocking support bearings?

Short-term (up to 1-2 weeks) - yes, but it’s not worth the risk. On Almera Classic a worn bearing leads to:

• accelerated wear of the shock absorber (oil leakage after 5–10 thousand km);
• loss of directional stability at speeds over 80 km/h;
• the risk of the rod being “pulled out” during a strong impact (for example, hitting a curb).

If the knocking has appeared recently, you can go to a service center, but avoid sudden maneuvers and high speeds.

How to distinguish the knock of a support bearing from the knock of a strut?

On Almera Classic there is a simple test:

1. When driving over uneven surfaces, slow down slightly. If the knocking noise disappears, the bearing is to blame (when braking, the load is redistributed and the play disappears).
2. If the knocking noise remains, the problem is in the rack or its mounting.

Also, support bearings knock more often low speed (up to 30 km/h), and the racks - on large bumps.

Do I need to replace the support bearings as a pair?

Not required, but recommended. On Almera Classic Bearings wear out at about the same rate, and if one fails, the second will soon require replacement. The exception is if the car was in an accident or drove for a long time with a broken suspension on one side.

Savings when replacing a pair:

• the service life of new bearings will be the same;
• you won’t have to pay for wheel alignment again;
• simplifies diagnostics in the future (both bearings are of the same age).

Which support bearings are better - original or analogues?

Original bearings (54303-4M001) last longer (100–150 thousand km), but they are often counterfeited. Among the analogues tested:

• SKF VKBA 3603 — resource 80–100 thousand km, best price/quality ratio;
• KYB SM5336 — reinforced design, suitable for aggressive driving;
• SASIC 2005017 — budget option (resource ~60 thousand km).

Avoid Brands FEBEST And TRIALLI — they have frequent cases of premature wear (20–30 thousand km).

What should I do if there is still a knocking noise after replacing the support bearings?

The reasons may be as follows:

1. The support mounting nuts are loose — check the tightening torque (50–60 Nm).
2. Worn compression stroke buffer — it had to be replaced along with the bearing.
3. Damaged spring - Inspect for cracks or deformations.
4. Play in silent blocks of levers - their resource for Almera Classic ~120 thousand km.

If the knock is metallic and radiates into the steering wheel, check tie rod ends And ball joints.
