The short version

  • An F-350 wheel bearing splits on single or dual rear wheels. That changes the front part even though the difference sits at the back.
  • Four wheel drive is a hub assembly. Two wheel drive runs a serviceable bearing and seal for most of this truck’s life.
  • The rear axle bearing is a solid axle part in the housing, not a hub. The catalogs stop documenting it after 2008 or 2009.
  • Counting the rear tires and confirming the drivetrain narrows the front fastest. Most people skip that step.

It seems backwards that the rear configuration decides the front part on an F-350. The reason is simple. Dually trucks carry a higher rated front axle, and that changes the hub.

Two wheel drive trucks are a separate story, one this page did not previously cover. They use a serviceable bearing and seal at the front for most of the run, not a hub assembly.

Single or dual rear wheels

Count the rear tires first

On 2011 to 2016 four wheel drive trucks, 515130 is cited for single rear wheels. 515131 covers dual rear wheels in those same years.

Both are front parts. The rear configuration is what separates them, not anything about the front axle itself.

The extended axle question, and the years before it

2008 to 2010 splits further, and 1996 to 2004 splits by ABS and hub style

2008 to 2010 four wheel drive trucks are cited with 515082 for trucks without the extended axle. 515116 covers dual rear wheel trucks with the extended axle. 515081 covers single rear wheel trucks from 2005 to 2010.

Before that generation, 1999 to 2004 four wheel drive splits by single or dual rear wheels and by ABS type. One 1999 changeover also splits by a March build date. 1996 and 1997 use an older serviceable design entirely.

That build date split inside 1999 is easy to miss. A truck built before late March that year takes a different number than one built after.

Both cover the same fitment. Only the build date tells them apart.

Two wheel drive was missing here, and it is not simple either

2WD ran a serviceable front end long after 4WD moved to a hub

Two wheel drive F-350s used a Twin I-Beam axle with a serviceable tapered bearing set from 1996 through 2007. A Mono Beam axle option ran alongside it from 1999, with its own hub bearing numbers.

From 2008 the front moves to separate inner and outer bearing and seal listings. That pattern continues to the end of this span.

A 2WD F-350 does not use the dual or single rear wheel hub numbers above. Those apply to four wheel drive trucks only.

The rear axle bearing is a different job than the wheel bearing

Solid axle means a bearing in the housing, not a hub

The rear on this truck is a solid, full floating axle. The bearing sits inside the axle housing rather than bolting to the outside as a hub does.

The difference between that arrangement and a hub assembly is worth understanding before ordering. It is covered on the axle bearing page.

The catalogs that document this rear bearing stop cold after 2008 or 2009. Front coverage reaches much further than that.

That gap is real, and it is called out plainly in the table below.

F-350 wheel bearing part numbers

Catalog verified. Four wheel drive front is a hub assembly throughout. Two wheel drive front is a serviceable bearing and seal until 2008, then a bearing and seal listed separately. Rear is an axle bearing in the housing.

The rear axle bearing gap is real, not an oversight

Front coverage on this truck runs the full 1996 to 2019 span, for both drivetrains. The rear axle bearing is a different story entirely.

The catalogs that document a rear number stop at 2008 or 2009. From 2010 to 2019, matching the old part or the VIN is the honest answer.

Guessing at a number that does not exist in print helps no one.

What these trucks actually do

A one ton truck that never tows is rare. Towing defines hub life here more than mileage does.

A fifth wheel or gooseneck puts its pin weight over the rear axle, which is what the design expects. A conventional hitch puts the weight behind the axle instead, levering load onto the front.

Impact damage from a pothole or a curb strike works the same way here as on any truck. It is on the pothole page.

The cost is not the part

Heavy duty front hubs cost more than passenger car units, but the bigger difference is labor. Corroded fasteners on a truck this size take real time.

Budget for the labor rather than shopping the part down. A written number on the quote is worth confirming against the table above before the work starts.

Diagnosing an F-350 wheel bearing

  1. Confirm the drivetrain before anything else, since 2WD and 4WD do not share a front design.
  2. Count the rear tires and check the axle option on a 4WD truck.
  3. Weave at road speed and note the loaded side.
  4. Rock the wheel at twelve and six, expecting a stiff feel on a truck this size.
  5. Compare hub heat across the front axle after towing.

The full checking process is on the checking page, and separating it from tire noise is on the tire noise page.

Common questions

Why does the rear axle change an F-350 wheel bearing at the front?

Dually trucks carry a higher rated front axle. That changes the front hub even though the rear is what differs.

Is my truck two wheel drive or four wheel drive under the hood?

Confirm before ordering. The two drivetrains use entirely different front designs on this truck, not just different numbers.

Why is there no rear number listed after 2009?

The catalogs behind this table stop documenting the rear axle bearing there. Matching the old part or the VIN is the honest path for a newer truck.

Is the rear a hub like the front?

No. It is a bearing built into the solid axle housing, which is a different job than a bolt on hub.

Do I need a press?

The four wheel drive F-350 wheel bearing is bolt on. The two wheel drive serviceable bearing and the rear axle bearing both need proper tools and a fight with corroded fasteners.

About this page

Wheel Bearing Editorial Team The Wheel Bearing Editorial Team researches, builds and edits wheelbearing.net. Every part number on the site is transcribed from manufacturer and distributor catalogs (Moog, Timken, SKF, National, BCA/NTN) rather than generated, and every vehicle page is checked against the catalog rows before it goes live. When two catalogs disagree, the page shows both readings and tells you to match the old part or the VIN. More about how this site is built.
