Parts for your 2012 Nissan Pulsar-Wheel hubs

2012 Nissan Pulsar wheel hubs

Wheel hubs are absolutely used on the 2012 Nissan Pulsar. Technical references that confirm this include the Nissan Factory Service Manual for the B17/C12 series (2012–2013), where Section FAX (Front Axle) and RAX (Rear Axle) describe the front wheel hub and bearing unit and the rear hub assembly for both disc and drum variants. Industry data sources such as Autodata/HaynesPro also list a bolt-on front hub with integrated bearing and ABS encoder for these models, and the Nissan EPC/FAST parts catalogue groups the front hub/bearing under 40202 and the rear hub/bearing under 43202. So, wheel hubs are relevant, fitted, and serviceable items on this vehicle.

On a 2012 Pulsar, the wheel hub assembly is the bit that the wheel bolts to via studs, housing a sealed bearing that lets the wheel spin smoothly and accurately. It also provides the mounting face for the brake rotor or drum and, on ABS-equipped cars, carries the encoder tone ring the sensor reads for wheel speed. Precise hub performance is what keeps the ride quiet, the steering true, and the ABS/traction control happy.

These hubs are sealed units, so there’s no greasing or bearing adjustment during routine servicing. Instead, the smart play is regular inspection. At each service, a technician should check for bearing play, roughness or droning noises on a road test, uneven tyre wear, and any ABS warning lights. Many Pulsars will see 100,000–200,000 km before any hub attention is needed, but that depends on road conditions and wheel impacts.

• Tell‑tale signs: humming that rises with speed, a growl while cornering, ABS faults, vibration, or heat at the hub.
• Checks: spin and feel for roughness, rock the wheel at 12/6 o’clock for play, scan for ABS codes.

When replacement’s due, the hub/bearing is swapped as an assembly. Correct torque on the axle/hub nut and the wheel nuts is critical, and any one‑time‑use nuts or bolts should be renewed per the factory manual. Avoid hammering on the hub face to protect the bearing and ABS encoder. If the knuckle-to-strut bolts are loosened, a wheel alignment is a good idea afterwards. Quality aftermarket or genuine assemblies tend to last longer and run quieter.

To extend hub life, keep wheel nuts torqued properly, rotate tyres on schedule, and avoid kerb hits and deep potholes. If a hub is noisy, it’s best sorted sooner rather than later—driving on a failing bearing can escalate to brake, ABS, and tyre issues.

Popular questions about 2012 Nissan Pulsar wheel hubs

How long do the factory wheel hub bearings usually last?
Most Pulsar hubs run a long innings—often 100,000 to 200,000 km—depending on road quality, wheel impacts, tyre size, and load. Cars doing lots of motorway kilometres on smooth roads usually see the best life. Once noise or play turns up, replacement is the fix.

Can the Pulsar’s wheel hubs be re‑greased or adjusted?
No. They’re sealed, maintenance‑free units. If a bearing becomes noisy, rough, or loose, the complete hub assembly is replaced. Regular inspections and correct wheel nut torque help them last.

Should both front or both rear hubs be replaced together?
Not necessarily. It’s fine to replace only the faulty side, but it’s sensible to assess the opposite side for noise or play at the same time. If the other side is close to the end of its life, doing both can save a second visit.
