The short version
- A 2008 Hummer H3 wheel bearing front order depends on which catalog is open: Moog and National do not agree on when the number changes.
- National lists 515093 all the way through 2009, while Moog switches to 515128 at 2009 and keeps 515093 for 2007-2008.
- Timken sidesteps the dispute with its own SKU, SP550311, for 2006-2009.
- The rear is simple by comparison: bearing 513067 and seal 4762N cover 2006 through 2010.
Three catalogs, three different answers for one front hub. A 2008 Hummer H3 wheel bearing front order sits right in the middle of a real disagreement between Moog, National, and Timken about when the number changes. The rear, thankfully, does not have this problem.
The core numbers
Front hub 515093 covers 2006-2009 under National, and only 2007-2008 under Moog, which moves to 515128 for 2009-2010. Timken keeps its own number, SP550311, through 2009.
The rear bearing, 513067, and its seal, 4762N, run all five years without a catalog dispute.

This page covers the 2006-2010 Hummer H3: 2006, 2007, 2008, 2009, 2010. Other years live on the main Hummer H3 wheel bearing page.
The catalogs disagree on the front hub, and this is a genuine parallel listing situation, not a typo. National holds 515093 through 2009 while Moog switches to 515128 starting in 2009, and Timken lists SP550311 on its own.
Never treat these as interchangeable options to pick from freely. Match the number the old part carries, or confirm against the catalog you already trust for this truck.
Year by year
2006 adds a front axle differential set, SET36, on top of the front hub question, and the front hub itself is 515093 or SP550311 depending on catalog.
2007 and 2008 are the one stretch where National, Moog, and Timken line up: 515093 or SP550311, no split. 2009 reopens the dispute as Moog moves to 515128 while National keeps 515093 and Timken’s SP550311 window closes.
2010 settles on Moog’s 515128 alone, and a 2008 Hummer H3 wheel bearing job falls in the one stable stretch before the 2009 split. The rear bearing 513067 and seal 4762N never move across any of these years.
An H3T front hub with its own truck
The H3T pickup shares its 2009-2010 front hub number, 515128, with the H3 SUV covered here. That is stated plainly by the catalogs, not a guess about shared engineering.
Beyond that overlap, nothing here extends to the H3T’s own years or trims. This page covers the H3 SUV’s 2006-2010 range only.
Confirming drivetrain and axle hardware matters before any front order; see drive type and wheel bearings for how that check works.
Diagnosing a Hummer H3 wheel bearing
- Pull the old part number before ordering a replacement. Any 2008 Hummer H3 wheel bearing job, and especially a 2009 one, needs the old part to tell you which catalog family to match.
- Listen for a front growl that grows with speed. See wheel bearing noise in turns for how it typically presents.
- Rule out the tires first. See tire noise or wheel bearing for the difference between the two.
- Check for a rear ABS light alongside noise. See bad bearing and the ABS light for the pattern a failing rear bearing 513067 can trigger.
- Check for play with the wheel off the ground. Looseness at the front points at whichever hub number the truck currently carries.
Common questions
What wheel bearing does a 2008 Hummer H3 use?
A 2008 Hummer H3 wheel bearing job at the front uses 515093 under Moog or National, or SP550311 under Timken. This is the one stretch where the catalogs mostly agree.
What wheel bearing does a 2009 Hummer H3 use?
2009 is the disputed year: Moog lists 515128, National still lists 515093, and Timken’s SP550311 window ends here. Match the old part to know which one applies.
Why do the catalogs disagree on the front hub?
The catalogs simply do not line up on when the H3 front hub changed. Rather than guess, match the number stamped on the part being replaced.
Does the rear bearing have the same dispute?
No. The rear bearing, 513067, and its seal, 4762N, are consistent across every catalog and all five model years, 2006 through 2010.
What is the SET36 part from 2006?
SET36 is a front axle differential set listed only for the 2006 model year. It sits alongside the front hub question rather than replacing it.
