Front hub <em>Nissan X-Trail T32</em>: how to select and replace without errors

Front hub Nissan X-Trail T32 (2013–2020) is a critical component on which not only ride comfort, but also safety depends. Bearing wear or damage to the hub itself is manifested by a hum, vibration on the steering wheel and uneven tire wear. However, many owners face problems when choosing spare parts: original articles 40520-4M00A (left) and 40520-4M00B (right) are expensive, and analogues from SKF, NTN or Febi differ in quality and resource.

In this article we will look at how to determine whether a hub is faulty, which part numbers are suitable for X-Trail T32 with different engines (including hybrid versions), and we will give step-by-step instructions for replacement, taking into account typical errors. You will also find out why hubs with ABS require special attention when installing the sensor and how to avoid premature failure of a new bearing.

Signs of a bad front hub: when is it time to replace it?

The first symptoms of a problem with the hub Nissan X-Trail T32 Often attributed to wheel imbalance or tire wear. However, ignoring them is dangerous: bearing destruction while driving can lead to wheel jamming. Pay attention to the following signals:

• 🔊 Hum or howl on the wheel side, increasing during acceleration. At an early stage, the noise may disappear when turning (for example, a hum on the right goes away when turning left - this indicates a right hub).
• 🚗 Vibration on the steering wheel or body, especially at speeds above 80 km/h. Often confused with imbalance, but vibration from the hub is more “ragged” and depends on the load on the wheel.
• 🔄 Wheel play when rocking in a vertical plane (checked on a jack). Even minimal play is a reason for replacement.
• 🔥 Hub overheating after the trip (you can check it with your hand by comparing the temperature of the wheels). A hot hub is a sign of a seized bearing.

On X-Trail T32 with the system ABS a faulty hub can cause the anti-lock braking system to malfunction: the light comes on ABS on the dashboard, or the brake pedal begins to “give” when braking hard. This is due to damage to the ABS sensor tone ring, which is often included with the hub.

⚠️ Attention: If on your X-Trail T32 alloy wheels with offset installed ET45, when the hub wears out, additional noise may appear due to changes in the wheel mounting geometry. Check the hub if a new sound appears after replacing tires or wheels.

Articles and analogues: what to choose for Nissan X-Trail T32

Original hubs from Nissan are supplied under article numbers:

• 🔧 Left (driver's side): 40520-4M00A
• 🔧 Right (passenger side): 40520-4M00B

They are suitable for all modifications T32 (2013–2020), including the 2017 restyling and hybrid versions. However, the price of the original starts from 8,000 rubles per piece, so many choose analogues. The table below shows verified brands and their articles:

When choosing an analogue, pay attention to:

1. Availability ABS tone ring (if your X-Trail equipped with this system). Some cheap analogues are supplied without it.
2. Bearing type: for T32 Only double row closed ball bearings are suitable (marking 2RS or LLU).
3. Complete set: the original set contains new hub mounting bolts (it is recommended to replace them).

Step-by-step replacement of the front hub: tools and nuances

Replacing the hub with Nissan X-Trail T32 requires a minimum set of tools, but there are several critical points. For example, When removing the drive shaft (CV joint), do not hit it with a hammer - this will damage the boot. It is also important to tighten the hub nut correctly: tightening torque - 180–200 Nm (for models with ABS - 220 Nm).

What you will need:

Jack and stops (or lift)|30mm and 32mm socket (for hub nut)|14mm and 17mm socket wrench|Bearing puller (or press)|Torque wrench|Hammer and wood spacer|WD-40 or equivalent for loosening stuck bolts-->

Work order:

1. Raise the car, remove the wheel and disconnect the sensor ABS (if any). Do not pull on the wires - only on the connector!
2. Unscrew the hub nut (force will be required - pre-process it WD-40 and use the lever).
3. Remove the brake caliper (hang it on a wire, do not leave it on the hose!) and the disc. On some versions T32 The disc may “stick” - carefully knock it down with a wooden mallet.
4. Disconnect the steering linkage and ball joint (a puller will be required).
5. Press the hub out of the steering knuckle. If the bearing is stuck, use a puller or press. Don't hit your fist with a hammer!
6. Install the new hub, observing the tightening torque. Tighten the hub nut only after the car is lowered to the ground (otherwise the bearing will quickly fail).

⚠️ Attention: On hybrid versions X-Trail T32 (for example, with an engine MR20DD + electric motor) when replacing the hub, it may be necessary to reset errors in the control unit VDC (stability control system). For this you need a diagnostic scanner, for example, Launch X431.

Typical replacement mistakes and how to avoid them

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

• 🔧 Retightening the hub nut. When the tightening torque is above 220 Nm, the bearing overheats and fails within 5–10 thousand km. Use a torque wrench!
• 🚫 Ignoring ABS Sensor. If the tone ring is damaged or installed crookedly, the system will malfunction. Check the gap between the sensor and the ring (should be 0.5–1 mm).
• 🔄 Reusing Old Bolts. The bolts securing the hub to the knuckle are disposable! When re-tightened, they stretch and do not provide the required torque.
• 🔥 Lack of lubrication on the seats. Before installing a new hub, apply a thin coat molybdenum grease to the seat in the fist. This will prevent corrosion and make future replacement easier.

Another common problem is incompatibility of hubs from different years of manufacture. For example, hubs for X-Trail T32 before restyling 2017 (with engines MR20DE) may not fit models after 2017 (with MR20DD), despite the same articles. Always check your vehicle's VIN number when ordering parts.

Hub with ABS vs. without ABS: what's the difference

On Nissan X-Trail T32 hubs are divided into two types:

1. With built-in ABS tone ring — installed on all trim levels with an anti-lock braking system (most cars on the market). The ring is a toothed ring that is read by a sensor.
2. No tone ring - rare, found on basic versions for some markets (for example, the Middle East). Such hubs are cheaper, but are incompatible with ABS.

Key differences:

If you buy a hub without ABS, and yours X-Trail T32 equipped with this system, you will have to either replace the sensor with a mechanical analogue (which is illegal in most countries), or look for an original spare part. Please note: on hybrid versions the sensor ABS is integrated into the regenerative braking system, and disabling it will lead to errors in the operation of the hybrid installation.

How long does a hub last? Nissan X-Trail T32?

The service life of the front hub depends on operating conditions, but on average:

• 🚗 Original hub: 100,000–150,000 km (with careful driving and no shocks).
• 🔧 High-quality analogues (SKF, NTN): 80,000–120,000 km.
• ⚠️ Budget analogues (Febi, no-name): 30,000–60,000 km (risk of premature failure).
