The short version
- The 2005 Trailblazer wheel bearing is one front hub number, 513188, used across the entire 2002-2009 run.
- No year, trim, or engine splits this front hub. It is the same part start to finish.
- The rear rides on a solid axle, so rear noise means axle-bearing work, not a hub order.
- One number covers eight model years with no exceptions in the front hub catalog.
The 2002 through 2009 Chevy Trailblazer covers eight model years on a single front hub number. A 2005 Trailblazer wheel bearing order is 513188, whether the truck is a base LS or an SS. The rear sits on a solid axle, so this page carries no rear hub number.

513188 covers the front hub for all eight years, with no split by trim, engine, or option package.
The rear rides on a solid axle. A rear rumble on this truck is axle-bearing work, not a hub replacement; see axle bearing versus wheel bearing.
Year by year
2002 through 2009 form one unbroken stretch. Every Trailblazer built across those eight years takes the same front hub.
A 2005 Trailblazer wheel bearing and a 2002 one are the identical part, 513188. Nothing about trim, engine, or year moves the number at any point in the run.
One hub number for the whole body
513188 is the only front hub listed for this generation, holding for all eight years without a change. Nothing in the catalogs splits it by trim, engine, or option package.
This front position is a bolt-on hub assembly, and many of these units come with the ABS sensor built in. Confirm that before ordering; see hub assembly and ABS sensor.
Diagnosing a 2002-2009 Chevy Trailblazer wheel bearing
- Confirm the noise is coming from the front. The rear on this truck is a solid axle, so rear symptoms point to axle-bearing work instead.
- Jack up the front wheel and check for play. Grab the tire at 12 and 6 and rock it; any looseness means the hub is worn. See how to check a wheel bearing.
- Listen for a hum that grows with speed. A failing front hub usually gets louder the faster the truck goes.
- Watch the ABS light along with the noise. A worn hub sensor can trip the light early. See a bad bearing and the ABS light.
- Rule out tire wear before ordering a hub. Cupped tires can mimic a bearing hum at highway speed. See tire noise or wheel bearing.
