The short version
- A 2004 Ford F350 wheel bearing depends on rear wheel count and ABS type. Single rear wheel trucks with 4 wheel ABS use 515056 that year.
- Dual rear wheel trucks with 4 wheel ABS use 515057 from 2003 on. Rear wheel ABS trucks keep 515021 across the whole 2000 to 2004 span.
- 1999 is a build date minefield. Three front positions change mid year, all near the same March line.
- 2WD trucks stay serviceable throughout. The rear splits by axle, a 10.5 inch ring gear or a Spicer 80.
Six model years of Ford F350 pickups hinge on ABS type as much as rear wheel count. This page covers 1999 through 2004 Super Duty F350 trucks, the generation before the 2005 redesign. A 2004 Ford F350 wheel bearing question always starts with rear wheel count and ABS type before any number gets quoted.
Ford F350 wheel bearing numbers by configuration
The same truck with rear wheel ABS instead uses 515021, unchanged since 2000.
Dual rear wheel trucks with 4 wheel ABS use 515057 from 2003 on, after 515025 covered 2000 through 2002.

This page covers the 1999-2004 Ford F350: 1999, 2000, 2001, 2002, 2003, 2004. Other years live on the main Ford F350 wheel bearing page.
1999 is a build date minefield. Three front positions split near the same March 1999 line, and the catalogs print overlapping dates on either side of it.
ABS type decides the single rear wheel number every year after that, not just the calendar.
Year by year
1999 splits by build date on three positions. Early trucks carry 515075, 515076, or 515077 by configuration, and later trucks move to the numbers that run through the early 2000s. The catalogs print overlapping March dates for the split, so a truck built that month should be matched off the old part.
2000 through 2002 settles into one number per configuration: 515020 for 4 wheel ABS, 515021 for rear wheel ABS, and 515025 on dual rear wheel trucks.
2003 and 2004 bring a new number on 4 wheel ABS trucks. A 2004 Ford F350 wheel bearing is 515056 on single rear wheel trucks, or 515057 on dual rear wheel trucks.
ABS type matters as much as the year
This F350 follows the 1992-1997 F350, where the whole truck ran one serviceable set. Hub assemblies and ABS splits only start with this generation.
The next chapter, the 2005-2010 F350, carries its own separate numbers.
Rear wheel count and ABS type decide the front number here, not just the year printed on the door.
Diagnosing a Ford F350 wheel bearing
- Rule out the tires first. Uneven wear can sound like a bad bearing. Compare against tire noise or wheel bearing symptoms.
- Check for play. Jack up the wheel and rock it at twelve and six. See how to check a wheel bearing for the full steps.
- Watch the ABS light. A failing hub with a built in sensor ring can trip the ABS light before it gets loud.
- Confirm rear wheel count first. Single or dual rear wheels split almost every number on this truck. Check that before checking ABS type.
- Know the rear is different. The rear axle is axle bearing work, split by ring gear size, not a front hub swap.
