Parts for your 2020 Nissan Serena-Wheel bearings

2020 Nissan Serena wheel bearings — what they do and when to replace them

Referencing Nissan’s C27 Serena Electronic Service Manual (Front Axle/Rear Axle sections) and Nissan’s FAST parts catalogue listings for “Hub &, Bearing Assembly – Front/Rear Wheel”, the 2020 Serena is fitted with sealed, integrated wheel bearings (hub units) at all four corners, so wheel-bearings are absolutely relevant service items on this model.

On the 2020 Nissan Serena, the wheel bearings are built into the wheel hub assemblies. Their job is simple but vital: let the wheels spin smoothly with minimal drag while carrying the weight of the people-mover, coping with cornering loads, braking forces and, on e-POWER and FWD variants, drive torque as well. These are modern, sealed “unitised” bearings (a third‑generation hub style widely documented by bearing makers like NTN/NSK), so there’s no routine greasing, when worn, the whole hub and bearing assembly is replaced.

Owners will often first notice a tired bearing as a road-speed hum or growl that gets louder when loading that corner (gentle lane changes are a giveaway). Because the Serena’s hubs use an integrated encoder ring for ABS/vehicle stability systems, a failing bearing can also cause an intermittent ABS or stability control light. Left too long, play can develop, leading to uneven tyre wear and vague steering feel.

• Typical signs it’s time to act:
  • Droning or rumbling that rises with speed and changes when turning
  • ABS or traction control warnings without a clear sensor fault
  • Disc brake pads rubbing inconsistently or heat on one corner
  • Noticeable play when rocking the wheel at 12 and 6 o’clock

As part of regular servicing, a quick road test and a spin-check on a hoist every 20,000 km is smart. There’s no maintenance to do inside the hub, but keeping tyres correctly inflated, avoiding potholes, and washing off coastal salt helps bearings live longer in Aussie and Kiwi conditions.

• Replacement tips owners should know:
  • Hubs are replaced as complete units, quality OEM-spec parts are worth it
  • The axle/hub nut is single-use and must be torqued to the factory spec
  • Clean the knuckle face before fitting so the hub seats dead flat
  • Wheel alignment may be needed if the knuckle was disturbed
  • No need to do both sides unless diagnostics suggest wear on each

Expect 1–2 hours per side in labour depending on corrosion and access. A tidy test drive afterwards to check for noise and an ABS scan to clear any stored faults rounds out the job.

FAQs

How long do 2020 Nissan Serena wheel bearings usually last?
Most Serena hub bearings will see 100,000–200,000 km, but life varies with loads, road quality, wheel/tyre choices, and coastal exposure. Potholes, heavy family or shuttle duty, and oversized wheels can shorten their lifespan.

Is it safe to drive with a noisy wheel bearing?
It’ll usually get louder before it fails, but driving on a noisy bearing isn’t recommended. Heat and play can escalate quickly, risking ABS sensor issues, uneven braking, and in extreme cases hub damage.

Do I need a wheel alignment after replacing a Serena hub?
If the steering knuckle was removed or shifted, getting an alignment is a good idea. If the hub was swapped without disturbing suspension geometry, alignment may not change, but a quick check is cheap insurance.
