Parts for your 2002 Nissan Pulsar-Wheel hubs

2002 Nissan Pulsar (N16) wheel hubs: what they do and when to replace them

Technical sources including the Nissan Pulsar N16 Factory Service Manual (Front/Rear Axle and Brake sections), the Nissan FAST parts catalogue, and common OE supplier listings (NTN/NSK/Timken) confirm the 2002 Nissan Pulsar is fitted with wheel hubs. Up front, the hub runs with a sealed, pressed-in bearing in the steering knuckle. At the rear, most drum-brake versions use an integrated hub-and-bearing unit, while disc-brake/ABS variants use a bolt-on hub assembly. So wheel hubs are absolutely relevant to the 2002 Pulsar.

On this model, the wheel hub is the solid mounting point for the wheel and brake rotor/drum, houses the wheel studs, and supports a sealed bearing so the wheel spins freely. On ABS-equipped cars, the hub or bearing also carries a tone ring that the sensor reads for wheel speed. A healthy hub keeps things smooth, quiet, and safe, reducing vibration and helping tyres and brakes wear evenly.

• Tell-tale signs it’s time: a humming or growling that rises with speed, ABS warning lamp, play at the wheel when rocked at 12/6 o’clock, uneven brake pad/shoe wear, or a hot hub after a short drive.
• Inspection tips during routine servicing (tyre rotations, brake work): spin each wheel and listen for roughness, check for free play, inspect studs and nuts, and look for damage to the ABS wiring at the hub.

The hubs and bearings on the N16 are sealed units, so there’s no periodic greasing. When worn or noisy, replacement is the fix. Front hubs typically require a press to swap the bearing in the knuckle, rear hub units are generally bolt-off/bolt-on. Always match parts to build date, stud pattern, and ABS configuration.

1. Use quality hub/bearing assemblies and new hardware (hub nut, split pin, dust cap) where specified.
2. Torque the axle/hub nut and wheel nuts to the factory specs with a calibrated torque wrench.
3. Avoid striking the new hub through the centre, press or pull using the correct adapters.
4. After fitting, clear any ABS faults and road-test for noise. No wheel alignment is usually needed unless strut-to-knuckle bolts were loosened.

As a rule of thumb, have the hubs checked at each brake service or every 20,000–30,000 kilometres. That keeps the Pulsar quiet, safe, and sweet to drive—and helps it sail through a WOF or roadworthy.

Popular question: Do 2002 Nissan Pulsars have serviceable wheel bearings or sealed hub units?
They’re sealed. The front uses a sealed bearing pressed into the knuckle with a separate hub, and the rear is typically an integrated hub-and-bearing assembly. There’s no greasing, when worn, they’re replaced.

Popular question: How can someone tell a Pulsar hub is failing?
Listen for a speed-related hum that changes when cornering, feel for play at the wheel, and watch for an ABS light or brake pull. A hot hub after a short drive is another giveaway.

Popular question: Is a wheel alignment needed after replacing a front hub?
Usually not, because the hub and bearing sit in the knuckle. If the strut-to-knuckle bolts are loosened or the subframe moved, then an alignment is a good idea.
