The short version
- Every Hummer wheel bearing story is a GM truck story: the H2 rides Tahoe hardware, the H3 rides Colorado hardware.
- H2 fronts: 515058 for 2003 to 2007, then a 2008 to 2009 listing the catalog itself prints two ways.
- H3 fronts: one number listed as 515093 in the applications and 515094 in the index, another recorded conflict.
- The military-derived H1 is serviceable at every geared hub and belongs to specialists.
Hummers look like nothing else on the road and bolt together like everything else in the GM catalog. The bearing chart underneath the attitude is plain truck hardware, with two catalog quirks worth knowing.
H2: the Tahoe in armor
A 2003 to 2007 H2 Hummer wheel bearing up front is the 515058 hub, straight from the full-size GM family.
For 2008 to 2009 the same catalog prints 515098 in its application pages and 515099 in its new-items index. Match your old part or the VIN.

H3: the Colorado underneath
The H3 shares its bones with the Colorado and Canyon, down to the 513067 rear axle bearing it also shares with the TrailBlazer family. Its front conflict resolves the usual way: the number stamped on your old hub outranks any list.
Off-road weight is the duty cycle
An H2 at full send is everything a bearing hates at once: maximum weight, shock loads and submersion.
Owners who actually wheel these treat front hubs as inspection items after every wet trip.
Water’s slow damage is on the water page, and weight’s role on the vehicle weight page.
Diagnosing a Hummer wheel bearing
- Match the old part’s number on any late H2 or H3 front, given the recorded conflicts.
- Weave at speed and place the hum.
- Rock each wheel at twelve and six.
- A rear H3 howl is the axle, not a hub.
- Ask about water history on any used example.
The routine is on the checking page, axle work on the axle bearing page.
Common questions
Which Hummer wheel bearing fits my H3 front?
The applications say 515093, the index says 515094. Your old hub’s stamping settles it.
And my 2005 H2?
515058, the full-size GM family hub of that era.
Why does one catalog give two answers?
Index rows drift against application pages; we record both rather than guess. It happens more than the industry admits.
What about the H1?
Geared hubs, serviceable everything, and a specialist ecosystem of its own beyond this site’s catalogs.
Do I need a press?
Not for H2 or H3 fronts. The H3 rear axle bearings, yes, or a shop.
