The short version
- The 2004 Ford Expedition wheel bearing front hub is 515042 on 2WD trucks or 515043 on 4WD trucks, the only split across all four years.
- This generation moved to an independent rear, and the catalogs do not carry a documented rear hub row for these years.
- Match the old part or confirm the rear by VIN, since no number is listed here for that end.
- Drivetrain is the only question at the front. The model year does not change which number applies.
2003 through 2006 is a short four-year window for this Expedition body before its next update. A 2004 Ford Expedition wheel bearing front order comes down to one question: two-wheel drive or four-wheel drive. The rear moved to an independent setup, but no catalog row documents its number here.

This page covers the 2003-2006 Ford Expedition: 2003, 2004, 2005, 2006. Other years live on the main Ford Expedition wheel bearing page.
This Expedition generation moved to an independent rear, away from the solid axle of the trucks before it. The catalogs do not carry a rear hub row for 2003 through 2006.
A 2004 Ford Expedition wheel bearing rear order has to start from the old part or a VIN lookup rather than a catalog number.
Year by year
2003 through 2006 share one front pair the whole way. 2WD trucks use 515042 and 4WD trucks use 515043, with no year splitting either number further.
The rear stays undocumented for all four years. Every rear order on this generation is a match-the-old-part job rather than a lookup.
An independent rear without a documented number
Earlier Expeditions rode a solid rear axle, the kind covered by axle bearing service rather than a hub swap. This 2003-2006 body switched to an independent rear, a real change in how the wheel is supported.
That change did not bring a documented rear hub row with it. A rear order on this generation depends on the old part or the VIN, not a chart.
Diagnosing a 2003-2006 Ford Expedition wheel bearing
- Confirm 2WD or 4WD first. That single question decides the front hub, 515042 or 515043.
- Jack up the wheel and check for play. Looseness in the hub means replacement. See how to check a wheel bearing.
- Match the rear to the old part. No catalog row documents the rear on this generation, so bring the old part or confirm by VIN.
- Watch the ABS light along with the noise. A failing hub can trip the light as its sensor wears. See a bad bearing and the ABS light.
- Rule out tire noise before ordering. Uneven wear can mimic a bearing hum at speed. See tire noise or wheel bearing.
Common questions
What wheel bearing does a 2004 Ford Expedition use?
A 2004 Ford Expedition wheel bearing front hub is 515042 on 2WD trucks or 515043 on 4WD trucks. The rear has no documented number; match the old part or confirm by VIN.
What wheel bearing does a 2006 Ford Expedition use?
The 2006 Expedition uses the same front pair as the rest of this generation, 515042 or 515043 by drivetrain. The rear is still undocumented for this year.
Why isn’t there a rear wheel bearing number for this truck?
The catalogs simply do not carry a documented row for the rear on this generation. That does not mean the part cannot be sourced, only that it has to be matched rather than looked up.
Does 2WD or 4WD change the rear number too?
Not that the catalogs document. The drivetrain split only applies to the front hub here; the rear has no listed number either way.
Is the rear on this Expedition a solid axle?
No. This generation moved to an independent rear. That is a different design from the solid axle used on earlier Expeditions, even though no catalog number documents it here.
