Home › Vehicles › Hummer › Hummer H3 Wheel Bearing Part Numbers
The short version
- The catalogs disagree on the Hummer H3 wheel bearing front hub. Moog switches from 515093 to 515128 at 2009, National keeps 515093 through 2009, and Timken lists a separate SKU, SP550311, for the whole 2006-2009 span.
- Because the sources conflict right at 2009, confirm the front hub by build date or VIN. Do not guess from the model year alone.
- The H3T pickup variant (2009-2010) uses 515128, the same number Moog lists for the later SUV.
- The rear bearing is 513067 with seal 4762N, part of the same truck family used on the S10 and Trailblazer.
The H3’s front hub is one of the messiest lookups on the site. Three catalogs list three different answers, and none of them should be averaged into one.
H3 wheel bearing numbers at a glance
Moog splits the front Hummer H3 wheel bearing at 2009. It switches from 515093 to 515128, while National keeps 515093 all the way through 2009.
Timken lists a different part number entirely, SP550311, for the same 2006-2009 span. That is its own SKU for the same bearing class.

Lookups run through the cross reference page.
Do not average these numbers or pick one at random. Moog, National, and Timken disagree on both the part number and the year the front hub changes, right at the 2009 break.
Confirm the correct front hub by build date or VIN before ordering. Match whichever catalog the shop already stocks from rather than mixing sources.
Shared with the S10 and Trailblazer
The rear bearing, 513067 with seal 4762N, comes from the same truck family used on the Chevy S10 and the Chevrolet Trailblazer. GM carried the same truck platform lineage across all three.
That shared rear end is one of the few uncomplicated parts of the Hummer H3 wheel bearing picture. The front hub is where the catalogs disagree.
The H3T and the front differential set
The H3T pickup, sold for 2009 and 2010, uses the later 515128 front hub. That is the same number Moog lists for the SUV starting that year.
The 2006 model year also has its own front axle differential set, SET36, separate from the wheel hub numbers. Browse the rest of the lineup on the Hummer hub.
Diagnosing a Hummer H3 wheel bearing
- Listen for a rhythmic hum. A worn Hummer H3 wheel bearing produces a growl or hum that rises and falls with road speed.
- Check for a change in a turn. Bearing noise usually gets louder turning away from the bad side and quieter turning toward it.
- Jack up the corner and check for play. With the wheel off the ground, grab it at 12 and 6 o’clock and rock it. Looseness points to hub wear.
- Spin the wheel by hand. Roughness, grinding, or clicking while spinning free points to a damaged bearing race.
- Confirm the build date before ordering. Given the 2009 catalog disagreement, note the VIN and build date before buying, not just after diagnosing the noise.
Common questions
Why do three catalogs list different Hummer H3 wheel bearing numbers?
Moog, National, and Timken each cover the front hub differently around the 2009 model year. Moog and National disagree on the breakpoint year, and Timken uses its own SKU, SP550311, for the same bearing class.
Which number is correct for a 2009 H3?
The catalogs do not agree, so treat 2009 as a confirm by VIN or build date year rather than trusting either breakpoint blindly.
Does the H3T use a different front hub than the SUV?
Not for 2009-2010. Both the H3T and the SUV use 515128 under Moog’s numbering for those years.
What is the rear Hummer H3 wheel bearing part number?
513067 for the bearing, with seal 4762N, shared with the S10 and Trailblazer truck family.
Is there a separate part for the front differential?
Yes. The 2006 model year lists a front axle differential set, SET36, separate from the hub bearing numbers.
