Home › Vehicles › Infiniti › Infiniti FX35
The short version
- The rear FX35 wheel bearing is catalog-solid: the 541002 hub for 2003 to 2009, FX35 and FX45 alike.
- The front splits by drivetrain: rear wheel drive takes 513334, all wheel drive takes the HA590125 hub.
- That AWD front serves half the Infiniti range, from G35x to M and EX, so listings run deep.
- A sports crossover on staggered tires eats fronts, and tire roar imitates the symptom perfectly.
Infiniti built the FX as a sports car on stilts, and the bearing bill follows the concept. The weight of an SUV, the cornering loads of a sedan, and wide tires shouting over the evidence.
Rear first, because it is simple
Both catalog sources list the rear FX35 wheel bearing as the 541002 bolt-on hub, 2003 through 2009, covering the FX45 too.
One number, both engines, no qualifiers.

The AWD front that serves everything
The HA590125 all wheel drive front also fits the G35x, EX35, M35x and more, which keeps prices honest for a luxury part.
The related sedan is covered on the G35 page.
Wide tires muddy the diagnosis
Staggered performance rubber drones louder as it wears than most bearings do, and FX owners replace good hubs chasing tire noise every day. Weave at speed: only the bearing changes its note with cornering load.
The separation method is on the tire noise page.
Both ends bolt on
No press work on this vehicle. Fronts and rears are complete hub assemblies, so the fight is rust in the hub bore rather than press tonnage. The make overview is on the Infiniti page.
Diagnosing an FX35 wheel bearing
- Confirm the drivetrain before ordering a front.
- Weave at highway speed and note whether the drone answers load.
- Rule the tires out first, especially with staggered fitments.
- Rock each wheel at twelve and six.
- Check the Q-family listings when pricing an AWD front.
The routine is on the checking page.
Common questions
Which FX35 wheel bearing fits the front?
513334 with rear wheel drive, HA590125 with all wheel drive. The drivetrain decides it.
Is the FX45 different?
No. The V8 car shares these numbers year for year.
Do I need a press?
No. Every corner is a bolt-on hub assembly.
Why does my new bearing still hum?
Odds are it was the tires all along. Wide performance rubber is this vehicle’s great imitator.
What about the 2009 onward FX?
The AWD front carries on; other corners shift with the refresh. Match a late truck by VIN.
Do these fail early?
Earlier than gentler SUVs, yes. Weight plus grip is a bearing tax, and the fronts pay it first.
