Parts for your 2019 Nissan Pathfinder-Wheel hubs

2019 Nissan Pathfinder wheel hubs — what they do and how to look after them

Wheel hubs are absolutely fitted to the 2019 Nissan Pathfinder (R52). The Nissan Factory Service Manual for the R52 platform (sections FAX – Front Axle and RAX – Rear Axle) details the front and rear wheel hub and bearing assemblies, and the Nissan electronic parts catalog lists complete hub units for this model (part numbers vary by VIN and drivetrain). These technical sources confirm the Pathfinder uses bolt-on, sealed hub-and-bearing assemblies with integrated wheel studs and ABS encoder functionality.

On a 2019 Pathfinder, each wheel hub supports the vehicle’s weight via a sealed bearing, provides the mounting face for the brake rotor and wheel, and keeps everything running true. On AWD variants, the hub is splined to the CV axle and retained by a large axle nut. The ABS system reads wheel speed from an encoder built into the hub/bearing, so a failing hub can also trigger ABS or stability control warnings. In short, the hub is the bit that lets the wheel spin smoothly and safely while keeping brake and suspension geometry happy.

They’re sealed-for-life units, so there’s no greasing or adjustment. During routine servicing, a tech should check for play at 12 and 6 o’clock, listen for a dull roar or growl that gets louder above 40–80 km/h, spin the wheel for roughness, and look for ABS warnings or uneven tyre wear. Avoid blasting the hub area with high-pressure washers and don’t hang a brake calliper off the hose during brake work.

• Replace the hub if there’s measurable play, roughness, rumbling, or ABS faults traced to the encoder/sensor ring.
• Front hubs are bolted to the knuckle, AWD models also have a staked axle nut. Follow FSM torque specs and use a new axle nut where specified.
• Unplug the wheel-speed sensor carefully, don’t twist or pry on the sensor head.
• Corrosion can seize hubs in the knuckle—use penetrant and correct pullers rather than hammering the CV or bearing.
• If the knuckle is loosened, get a wheel alignment check. Retorque wheel nuts after 50–100 km.

There’s no fixed replacement interval—inspect at every service and act on noise or play early to protect tyres, brakes, and driveline components. Quality, OE-spec hub assemblies keep the Pathfinder quiet, sure-footed, and safe on Aussie and Kiwi roads.

How can someone tell if a 2019 Pathfinder wheel hub is failing?

Typical signs are a humming or growling noise that changes with road speed (not engine revs), play when rocking the wheel at 12 and 6 o’clock, steering vibration, uneven tyre wear, or an ABS/vehicle dynamics warning. A quiet test drive on smooth tarmac helps pinpoint the noisy corner.

Does a wheel alignment need to be done after a hub replacement?

The hub itself doesn’t change alignment, but if the knuckle bolts are loosened or the strut is disturbed, an alignment check is smart. Even when everything’s kept intact, many shops recommend a quick alignment check to confirm camber and toe are still within spec.

Should both hubs be replaced at the same time?

It isn’t mandatory. Replace the proven faulty side. That said, on higher-kilometre Pathfinders, the opposite side may not be far behind, so owners sometimes choose to do hubs in axle pairs to save labour and a second visit.
