Nissan 22401-CK81B: explanation, where it is installed and how to choose the right replacement

If you encounter a part number 22401-CK81B in the catalog Nissan, then most likely we are talking about a suspension component - most often it is shock absorber strut support (or part thereof) for the front axle. This part is critical for safety and comfort: it dampens vibrations transmitted from the wheel to the body and fixes the position of the shock absorber. Support wear is manifested by knocking in the suspension, deterioration in handling, and even uneven tire wear.

But there is a nuance: the same article 22401-CK81B may indicate other elements depending on the model Nissan. For example, in some versions X-Trail T31 or Qashqai J10 hiding under this number upper spring cup or even support bearing. In order not to make a mistake with a purchase, you need to know for sure Vehicle VIN or year of manufacture - this will help clarify the applicability of the part through catalogs Nissan Parts or ETKA.

What does article number 22401-CK81B mean: decoding the code

Number 22401-CK81B consists of several parts, each of which carries information about the part:

• 🔢 22401 — base code of a group of parts. In case Nissan this usually points to elements front suspension (supports, cups, bearings).
• 🅱️ CK81B - suffix defining specific modification details. The letters and numbers here encode applicability to models, materials and even supplier (e.g. Kayaba or Tokico).
• 📌 Last letter (B) may indicate a revision of a part—for example, a changed design or material to improve reliability.

Important: Nissan Often there are “mirror” articles for the left and right sides. For example, for a rack support, the right side might have the suffix -CK81B, and the left one - -CK80B. Always check the installation side when ordering!

What Nissan models fits 22401-CK81B?

Part with article number 22401-CK81B most common in the following models:

Model Nissan	Years of manufacture	Note
Qashqai J10	2006–2013	Front right strut support (for 1.6/2.0 engines)
X-Trail T31	2007–2013	Upper spring cup (complete with bearing)
Pathfinder R51	2005–2012	Strut support (front-wheel drive versions only)
Teana J32	2008–2013	Support bearing (less common, needs clarification)

⚠️ Attention: On Qashqai J11 (2014+) and X-Trail T32 (2014+) this article no longer fits - they use supports with a different fastening (for example, 22401-JM00A). Also, the part may differ depending on the type of drive (2WD/4WD) and engine.

To avoid the error, check compatibility via:

• 🔍 VIN decoder (for example, on the website Nissan or through the service VinDecoderz).
• 📋 Spare parts catalogs: Nissan EPC, Amayama, Exist.ru.
• 📸 Photo comparison: Ask the seller to send photos of the part from different angles and compare it with your old support.

Symptoms of mount failure 22401-CK81B

Wear on a strut support or bearing appears gradually, but ignoring the symptoms is dangerous - it can lead to the destruction of the strut or loss of control over the car. Basic "bells and whistles":

• 🔊 Knocking or squeaking when driving over bumps (especially at low speeds). The sound usually comes from under the hood from the direction of the problem pillar.
• 🚗 Deterioration in handling: the car “steers” to the side, the steering wheel becomes less informative.
• 🔄 Uneven tire wear (especially along the inner edge) due to wheel alignment violation.
• 💨 Vibrations on the steering wheel when driving on a flat road (indicates the destruction of the support bearing).

🔧 How to check the support yourself?

1. Open the hood and have a helper rock the car up and down by the front fender.
2. Place your hand on the strut support (it is located under the “glass” in the engine compartment).
3. If you feel play or hear a knock, the part must be replaced.

What happens if you drive with a broken support?

In addition to discomfort, a worn support leads to:

- **Loss of directional stability** at high speed (the car may “yaw”).

- **Damage to the shock absorber** - the strut begins to work at the wrong angle.

- **Spring break** - if the support is completely destroyed, the spring may jump out of the “glass”.

- **Emergency** during sudden braking or maneuvering (risk of the strut “collapsing”).

Analogs and substitutes: what to choose instead of the original?

Original support Nissan with article number 22401-CK81B costs from 4,000 to 7,000 rubles (depending on the supplier). However, there are high-quality analogues on the market, which are often not inferior in terms of resource, but are 30–50% cheaper. Best replacement brands:

Brand	Article	Price (≈)	Features
Kayaba (KYB)	SM5400	3 200 ₽	Japanese quality, bearing included
Tokico	GS-54001	3 800 ₽	Original supplier for Nissan, resource 100+ thousand km
Febi	22401	2 900 ₽	German brand, good price/quality ratio
Sasic	2005400	2 500 ₽	Budget option, but the bearing is rather weak

⚠️ Attention: When purchasing an analogue, pay attention to:

• 🔄 Availability of bearing — in some sets it comes separately (for example, 40520-CK800 for Qashqai).
• 📦 Completeness: The original often comes with mounting bolts, but the analogues do not.
• 🏭 Country of manufacture — avoid “no-name” brands from China (the service life of such supports rarely exceeds 30 thousand km).

Step-by-step instructions for replacing support 22401-CK81B

Replacing a strut support is a moderately difficult task. If you have a tool and an inspection hole (or a lift), you can do it in 2–3 hours. You will need:

• 🔧 A set of sockets and keys (required for “17”, “19” and “21”).
• 🔩 Clamps for springs (or a special puller).
• 🛠️ WD-40 or similar penetrating lubricant.
• 🔴 Jack and stops (if there is no hole).

📌 Work order:

Disconnect the battery (remove the negative terminal)|Loosen the wheel nuts (car on the ground)|Raise the car and remove the wheel|Clean the threaded connections from dirt-->

1. Removing the stand:
   • Unscrew the shock absorber rod nut (you will need a "17" wrench and a hexagon to fix the rod).
   • Disconnect the brake hose from the bracket on the rack.
   • Unscrew the two bolts securing the strut to the steering knuckle (key set to “19”).
2. Disassembling the rack:
   • Clamp the spring with clamps (observe safety precautions!).
   • Remove the top stem nut and dismantle the support.
3. Installing a new support:
   • Check the condition of the bearing (replace if necessary).
   • Install the new support, observing the assembly order (the spring must fit into the grooves of the cup).

⚠️ Critical points:

• 🔴 Do not use a percussion instrument when unscrewing the nuts, this can damage the threads on the shock absorber rod.
• 🔄 After replacement, be sure to do a wheel alignment - even if outwardly the wheels are straight.
• 🔧 Tightening the rod nuts Perform only with a loaded suspension (the machine must be on wheels).

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes that shorten the service life of a new support. Here are the most common:

• 🔩 Not tightening the nuts - leads to play and repeated knocking. Solution: use a torque wrench (tightening torque for Qashqai - 45–55 Nm).
• 🔄 Mixed up sides — the left and right supports may differ in design. Solution: check the marks on the parts.
• 💥 Boot damage during installation - this will lead to dirt getting into the bearing. Solution: Lubricate the boot with silicone grease before assembly.
• 🚗 Ignoring wheel alignment - even a minimal shift in angles will affect handling. Solution: visit the stand immediately after replacement.

🔧 Advice from the experts: If you are replacing a mount on a car older than 10 years, inspect other suspension components:

• 🔍 Shock absorbers — if they “leaked”, it’s time to change them too.
• 🔄 Ball joints — the play in them will increase the load on the new supports.
• 🛡️ Silent blocks of levers - cracks or peeling of rubber indicate the need for replacement.

FAQ: Answers to frequently asked questions about 22401-CK81B

Is it possible to drive with a knocking strut support?

Short-term (up to 1-2 weeks) - yes, but it’s not worth the risk. Collapse of the support can lead to loss of control, especially on uneven roads. At the first sign of a malfunction (knocking, vibration), sign up for diagnostics.

How to distinguish an original support from a fake?

Original part Nissan has:

• Clear markings 22401-CK81B (no extraneous characters).
• An even weld seam on the cup (counterfeits are often curved or have sagging marks).
• Bearing with logo NTN or Koyo (on analogues it may be nameless).

Buy only from authorized dealers or trusted suppliers (for example, Exist.ru, Amayama).

Do I need to replace the supports in pairs?

Not required, but recommended. If one support is worn out, the second is usually also close to its limit state. Replacing them in pairs will ensure uniform operation of the suspension and eliminate the need for repeated repairs after 20–30 thousand km.

How long does the 22401-CK81B rack support last?

Service life depends on operating conditions:

• 🌆 City mode (flat roads): 80–120 thousand km.
• 🏔️ Off-road driving: 50–80 thousand km.
• ❄️ Operation in aggressive climates (salt, temperature changes): 60–90 thousand km.

Regular washing of the suspension and careful driving will extend the life of the part.
