Parts for your 2001 Nissan Serena-Wheel hubs

2001 Nissan Serena wheel hubs: what they do and how to look after them

Wheel hubs are absolutely fitted to the 2001 Nissan Serena (C24). This is confirmed by the Nissan Serena C24 Factory Service Manual—see the Front Axle (FA) and Rear Axle (RA) sections—and the Nissan FAST electronic parts catalogue, which both show front hub-and-bearing units in the steering knuckles and rear hub assemblies (with ABS tone rings where equipped). These technical sources make it clear the Serena relies on wheel hubs as the mounting point for each wheel and brake disc/drum, and to support the integrated wheel bearings.

On a 2001 Serena, the wheel hub’s job is pretty straightforward but critical. Up front, the hub sits through the wheel bearing in the knuckle, splined to the driveshaft to transmit torque to the wheel. At the rear, the hub assembly supports the wheel and brake hardware, and on ABS models carries the tone ring that lets the ABS sensor read wheel speed. The hub keeps everything running straight and smooth, so the van tracks properly and doesn’t chew out tyres or make a racket on the motorway.

Good servicing practice for Serena wheel hubs focuses on inspection and correct fastener torque, rather than routine replacement. During scheduled services, technicians should:

• Spin and feel for roughness or notchiness at each wheel, and listen for rumbling that changes with road speed.
• Check for play by rocking the wheel at 12 and 6 o’clock, any looseness needs investigating.
• Inspect ABS sensor gaps and tone rings for rust, cracks or missing teeth if an ABS light is on.
• Look for weeping or contamination at bearing seals and any heat discolouration on the hub.

When replacement is needed, it’s best practice to do the job by the book: support the knuckle properly, press bearings squarely (where applicable), and always torque the axle/hub fasteners to the specification in the Nissan FSM. Replace single-use parts such as staked axle nuts and any cotter pins. Avoid water blasting directly at bearing seals and don’t hang brake callipers or the driveshaft by their hoses/boots. Quality hub and bearing components make a noticeable difference to cabin noise and tyre life, so owners of high-kilometre Serenas will appreciate the payoff in quieter, safer touring.

Popular questions about 2001 Nissan Serena wheel hubs

How can someone tell if a Serena hub or bearing is failing?
Common signs include a humming or growling that gets louder with road speed, a grinding feel when spinning the wheel off the ground, and play at the rim when rocked top-to-bottom. On ABS-equipped vans, a cracked tone ring or noisy bearing may trigger the ABS light or cause pulsing at low speeds.

Are the front and rear hubs the same on a 2001 Serena?
No. The fronts are part of the driven assembly with a splined centre for the driveshaft and are pressed into or supported by the front bearing and knuckle. The rears are non-driven on most models and may be a bolt-on hub unit. ABS tone ring and sensor arrangements also differ front to rear per the FSM and parts catalogue.

Can the bearing be replaced separately, or does the whole hub need changing?
Up front, the bearing is typically a press-fit in the knuckle with the hub installed through it, so the bearing can be replaced separately with the right tools. At the rear, many Serena variants use a hub assembly with an integrated bearing, making it a bolt-off, bolt-on unit. Always follow the C24 FSM procedure for the specific axle type.
