The short version
- 2004-2007 QX56 front hub assembly is SP500701; 2008-2009 trucks switch to SP500703, a mid-run change.
- Rear hub assembly is SP500702 for the 2004-2009 run, no split.
- The 2011-2013 QX56 wheel bearing resolves too: 515127 front, 541016 rear, both bolt-on hub assemblies.
- A 2014 or newer QX56 wheel bearing is a different generation and sits past the catalogs; match by VIN.
Infiniti built the QX56 as a badge engineered twin to the Nissan Armada, sharing everything from frame to hub. This three ton family truck does not go easy on its corners.
A gap in the middle of its production run looked permanent for a while. Newer catalog data closes most of it.
Front and rear numbers by era
Front hub assembly is SP500701 for 2004-2007, then SP500703 for 2008-2009.
Rear hub assembly is SP500702 across the 2004-2009 run.
The 2011-2013 truck resolves after all
An earlier read on this truck found no listing for the 2011-2013 QX56 wheel bearing and called that generation undocumented.
Newer catalog data prints both a front and a rear hub assembly for that truck, 515127 and 541016, so the earlier finding predates the fuller picture.

Every model year this chart resolves: 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 and 2013. A 2014 or newer QX56 sits past the catalogs and goes by the old part or the VIN.
Infiniti renamed the truck QX80 for 2014, and that newer truck runs its own separate hub listings.
Do not carry a QX80 number back onto a 2011-2013 QX56 listing, or a QX56 number forward onto a 2014 or newer truck. The two generations do not share this chart.
The chart carries parallel listings for the same corners. The SP series numbers and the 515 and 541 series numbers both print for the 2004-2010 truck, so match the number the old part carries.
Lookups run through the cross reference page.
Same truck as the Armada
The QX56 is a dressed up Nissan Armada, and the two share every hub number on this chart. Cross-shopping Armada listings prices every corner of a QX56 wheel bearing job, or get a baseline on the quote page.
Infiniti changed little beyond trim and badges against the Nissan version.
The underlying hardware stayed identical through the 2004-2009 run, and the same pattern carries into the 2011-2013 numbers.
A truck that works its bearings hard
At close to three tons loaded, the QX56 leans on its front and rear hubs more than a car based crossover does. Towing and full passenger loads add steady stress that a lighter vehicle never sees.
A pothole hit at that weight does more damage too, covered generally on the pothole page.
A hub that starts humming after a rough road is worth checking soon rather than waiting for it to get louder.
Diagnosing a QX56 wheel bearing
- Listen under load. A failing QX56 wheel bearing often gets louder when the truck is loaded or towing.
- Compare front and rear. Note which end the noise favors before ordering a hub assembly.
- Rock the wheel by hand. Play at nine and three o’clock means a worn hub assembly. See how to check a wheel bearing for the steps.
- Rule out tires first. Tire noise stays constant regardless of steering input, unlike a bad bearing.
- Match the year before ordering. Confirm whether the truck falls in the 2004-2009 span or the 2011-2013 span before buying a hub.
