Nissan Bluebird is a legendary sedan that has gained popularity due to its reliability and unpretentiousness. However, even such machines have weak points, and one of them is hub unit. Wear of the hub or its bearing can lead to dangerous consequences: from increased noise to complete loss of control at speed. In this article we will look at how to correctly diagnose a malfunction, choose a quality part and replace it without errors.

Feature Bluebird (especially models U13, U14, U15) - the design of the front and rear suspension, where the hub is integrated with the bearing into a single unit. This simplifies replacement, but requires precise selection of spare parts. We have collected current article numbers of original and analog parts, as well as step-by-step instructions with nuances that are not written about in standard manuals.

Signs of a bad Nissan Bluebird hub

The first symptoms of a hub problem are often ignored until they become critical. Here are the key signals you shouldn't miss:

  • 🔊 Hum or howl on the wheel side, increasing at speeds above 60 km/h. The sound may disappear when turning (for example, when turning left, the right hub makes noise and vice versa).
  • 🔄 Wheel play, which is felt when swinging it with your hands in a vertical plane (checked on a jack).
  • 🚗 Vibration on the steering wheel or body, especially when braking - this may indicate deformation of the hub or wear of the bearing seat.
  • 🔥 Wheel overheating after the trip (you can feel it with your hand - carefully!). Indicates a seized bearing.

On Nissan Bluebird U14 with ABS, a faulty hub can cause false activation of the ABS sensor (the light on the dash lights up). This is due to the fact that the sensor reads pulses from the hub gear, and when it beats, the signal becomes unstable.

⚠️ Attention: If while driving there is metallic grinding - This is a sign of complete destruction of the bearing. It is strictly prohibited to operate the car in this condition: the wheel may jam!

For an accurate diagnosis, use mechanic's stethoscope or a long screwdriver: attach its metal end to the hub and the handle to your ear. This way, even a faint bearing hum can be heard at an early stage.

Original articles and hub analogues for Bluebird

Selection of hub for Nissan Bluebird depends on the generation, drive type and the presence of ABS. Below is a table with original articles and proven analogues:

Model Position Original article Analogs (brand + article) Note
U13 (1987–1991) Front (without ABS) 40520-40X00 SKF VKB 3535, NSK 40BWD02 Suitable for versions with engines CA18i, SR20Di
U14 (1991–1996) Front (with ABS) 40520-40X05 NTN 512078, Febi 22610 Complete with ABS sensor
U15 (1996–2001) Rear 40530-4M000 Koyo DAC40720038, SNR R154.50 Only for all-wheel drive versions Attesa E-TS

When choosing an analogue, pay attention to:

  • 🔧 Availability of ABS sensor (if it is in the original, it should be in the replacement).
  • 📏 Bore hole size - for U14 with engine SR20DE it may differ from versions with GA16DE.
  • 🔄 Bearing type: ball or roller (indicated in the catalogue).
⚠️ Attention: Cheap hubs without a brand (for example, "no-name" from China) often have misalignment of seating surfaces, which leads to wheel runout after 10–15 thousand km. Savings of 2–3 thousand rubles will result in repeated repairs.

Check the package before purchasing: the box should contain a hub, a bearing (if not pressed in), a retaining ring and, if necessary, an ABS sensor. For example, at Febi 22610 The sensor comes separately - its article number 22611.

Step-by-step replacement of the Nissan Bluebird hub

Replacing the hub with Bluebird requires a minimum set of tools, but there are nuances depending on the generation of the model. Let's look at the process using an example U14 (the most common option).

Required tools:

  • 🔧 Spanners for 17, 19, 22 and 30 mm.
  • 🔨 Wheel bearing remover (or press).
  • 🔩 12mm socket for brake caliper bolts.
  • 🛠 Hammer and wooden spacer (for knocking out the hub).
  • 🧲 Torque wrench (for tightening the hub nut with a torque of 180–220 Nm).

Work order:

  1. Jack up the car, remove the wheel and brake disc. On models with ABS, disconnect the sensor connector.
  2. Unscrew the hub nut (it is tightened with a large torque - you may need an extension for the wrench).
  3. Remove the caliper by hanging it on a wire (do not let it hang on the hose!).
  4. Press out the hub using a puller or carefully knock it out with a hammer through a wooden spacer.
  5. Install the new hub, having first cleaned the seat from rust and dirt. Use copper grease for bolts.
  6. Tighten the hub nut with a torque wrench (the torque is indicated in the manual for your model).

Check the integrity of the bearing boot|

Apply a thin layer of lubricant to the seat|

Make sure the ABS sensor (if equipped) is oriented correctly|

Tighten the hub nut in 2 stages: first until it stops, then to the required torque-->

On U13 And U15 The process is similar, but there are differences:

  • On U13 The steering knuckle may need to be removed.
  • On U15 with QR25DE the hub is secured with 4 bolts (instead of 3 on U14).
💡

If the hub does not press out, heat it with a hair dryer to 100–120°C - the metal will expand and the part will move. Do not use open flame (such as a gas torch) as this will damage the bearing boot.

Typical replacement mistakes and how to avoid them

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

  1. Over-tightening or under-tightening of the hub nut. On Bluebird U14 the tightening torque should be 180–200 Nm for the front axle and 120–150 Nm for the back. Excessive torque leads to premature wear of the bearing, and insufficient tightening leads to backlash.
  2. Ignoring the condition of the brake disc. If the disc has a runout of more than 0.15 mm, it needs to be sharpened or replaced. Otherwise, the vibration will be transferred to the new hub.
  3. Lack of lubrication on the seating surfaces. Without it, the hub may “stick” to the fist, and the next time it is replaced it will have to be cut off.
  4. Incorrect installation of the ABS sensor. If the gap between the sensor and the ring gear exceeds 1 mm, the system will generate an error.

Another common problem is dirt getting into the bearing when replacing. To avoid this:

  • Work in a clean room (not outdoors).
  • Do not place the new hub on the ground.
  • Wipe the seat before installation degreaser.
What happens if you don't replace the hub on time?

If the bearing is completely destroyed, the wheel may jam at speed, which will lead to loss of control. On Nissan Bluebird With front-wheel drive this is especially dangerous, since the load on the hub is higher than on rear-wheel drive models. In addition, a worn hub accelerates the destruction of the CV joint and brake disc.—>

How to extend the life of the hub

Average wheel bearing life is Bluebird - 100–150 thousand km, but with proper operation this period can be increased to 200 thousand km. Here's what you need for this:

  • 🚿 Avoid deep puddles. Water entering the bearing accelerates corrosion and washes away the lubricant. If you were unable to avoid a puddle, after driving, slow down several times to warm up and dry the unit.
  • 🔧 Check wheel play every 20 thousand km. Even a small gap (0.5 mm) is a reason for diagnosis.
  • 🛑 Don't brake suddenly at high speeds. This creates shock loads on the hub, especially on U15 with heavy engine QR25DE.
  • 🔄 Lubricate the seat every time you replace pads or discs. Use copper paste, not graphite grease.

On vehicles with ABS, monitor the condition of the sensor and its wiring. Contact oxidation or wire breakage can lead to false alarms of the system, which indirectly affects hub wear (due to uneven braking).

Cost of work and spare parts: where is it cheaper?

Hub replacement price Nissan Bluebird varies by region and type of service. Below are the estimated prices for 2026:

Service/Part Cost (RUB) Note
Original hub (front, with ABS) 8 000 – 12 000 Article 40520-40X05
Analogue (SKF, NSK, NTN) 4 500 – 7 000 The quality is not inferior to the original
Hub replacement (service station) 2 500 – 4 000 Excluding ABS diagnostics
Bearing puller (rent) 500 – 1 000 Many services are provided for free

Replacing it yourself will cost less, but will require tools. If it is not there, it is more profitable to contact the service. For example, in Moscow and St. Petersburg the average price of work is 3,500 rub. for one side, and in the regions - 2,000–2,500 rub.

Where to buy spare parts?

  • 🏬 Official dealers - guarantee of original parts, but the price is 20-30% higher.
  • 🌍 Online stores (Exist, Autodoc, Emex) - a wide selection of analogues, often with discounts.
  • 🔧 Showdown - option for rare models (for example, Bluebird U13), but there is a risk of running into a worn part.
⚠️ Attention: When purchasing a disassembled hub, be sure to check condition of the bearing seat — often there is a working there that is not visible to the naked eye. Use dial indicator to measure runout.

Frequently asked questions about Nissan Bluebird hubs

Is it possible to drive with a humming hub?

For a short time (up to 500–1000 km) - yes, but only if the hum has appeared recently and there is no play. At the same time, avoid speeds above 80 km/h and sudden maneuvers. If the sound is accompanied by vibration or grinding, the movement is dangerous - the bearing may collapse at any moment.

How to distinguish a fake hub from the original?

Original hubs Nissan have:

  • Clearly marked with the article number and manufacturer's logo (for example, NTN or KOYO).
  • Even color without streaks or chips.
  • The bearing boot is made of high-quality rubber (does not harden in the cold).
  • Complete with instructions and warranty card.

Counterfeits are often lighter in weight and have rougher metal finishes.

Do I need to replace the hub as a pair?

Not necessary if the other side is in good condition. However, if the car’s mileage exceeds 150 thousand km, it is recommended to replace both hubs - most likely, the second one is also worn out, it just doesn’t make noise yet. Exception - Bluebird U15 with all-wheel drive: here the load is distributed more evenly, and replacement with a pair is not so critical.

What should I do if there is still a hum after replacing the hub?

The reasons may be as follows:

  1. Incorrect tightening of the hub nut (overtightened or undertightened).
  2. The bearing boot was damaged during installation.
  3. Worn CV joint (symptoms similar to hub noise).
  4. Defective new part (occurs from non-brand manufacturers).

It is necessary to remove the hub again and check all the elements.

Is it possible to restore a wheel bearing?

Technically, yes - the bearing can be disassembled, washed, and replaced with grease and seals. However, in practice this is not practical:

  • The cost of the work will exceed the price of a new bearing.
  • The quality of the restoration will be lower than the original.
  • Risk of repeated failure after 10–20 thousand km.

The exception is rare models (for example, Bluebird 910), where original spare parts are difficult to find.
