The short version
- 2001 Infiniti QX4 front wheel bearings are fully serviceable. The set is inner set SET37, outer cone and cup LM300849-LM300811, and seal 710072.
- The rear uses inner bearing assembly 516005 and seal 710176. Those listings hold for the whole 1997 to 2003 run.
- A 2WD QX4 arrived in 2001 and shares every one of these listings with the 4WD truck.
- Nothing on the QX4 front or rear is a hub assembly; every listing here is a serviceable part.
Infiniti sold the QX4 from 1997 through 2003 with serviceable bearings at both ends, never a sealed hub. 2001 Infiniti QX4 front wheel bearings are the same SET37 inner set, outer cone and cup, and seal used on every year of this truck. The rear matches that pattern with its own serviceable parts.

Nothing about the drivetrain changes the part numbers on this generation.
This page covers the 1997-2003 Infiniti QX4: 1997, 1998, 1999, 2000, 2001, 2002, 2003. Other years live on the main QX4 wheel bearing page.
Year by year
Every year from 1997 through 2003 uses the same five listings, front and rear alike. 2001 Infiniti QX4 front wheel bearings are identical to the front bearings on a 1997 or 2003 truck. The 2WD version joins the lineup that same year with the same listings.
Nothing changes by year on this truck. The only distinction worth tracking is that the 2WD variant did not exist before 2001.
Serviceable at both ends
The QX4 never moved to a sealed hub during this run. That means repacking is the normal service at both the front and rear. Getting preload and end play right after service matters as much as using the correct part numbers.
Serviceable bearings on a mid-size SUV this old are less common than they once were.
Diagnosing an Infiniti QX4 wheel bearing
- Check for grease around the hub. A failing seal on a serviceable bearing often leaves grease on the wheel or backing plate.
- Feel for play with the wheel off the ground. Rock the tire top and bottom with the truck safely supported; see how to check a wheel bearing.
- Listen for a hum that changes in a turn. A bearing that gets louder turning one way usually points to that side; see wheel bearing noise in a turn.
- Rule out tire wear. Cupped or unevenly worn tires can sound like a bearing at speed; see tire noise or wheel bearing.
- Recheck preload after any service. A serviceable bearing set too tight or too loose will fail again regardless of part quality.
