The short version
- A 2004 Chevy Astro front wheel bearing is the 2WD hub 515044. All wheel drive vans from 2003 to 2005 use one of three handed listings instead.
- The rear axle bearing is 513067 across all three model years. It is axle bearing territory, not a wheel hub.
- All wheel drive fronts are handed. The catalogs carry three listings split across the driver side and passenger side.
- Earlier Astro vans before 2003 use different front hubs. Those numbers live on the main Astro wheel bearing page.
Chevy built the Astro through the 2003 to 2005 model years with two different front ends. A 2WD van uses one hub number every year, while an all wheel drive van splits into handed listings. Sorting out a 2004 Chevy Astro front wheel bearing starts with the drivetrain.
Astro wheel bearing numbers, 2003 to 2005
The 2WD front hub is 515044 for all three years. Nothing about it changes by year.
All wheel drive vans use handed front hubs instead. A 2004 Chevy Astro front wheel bearing order on an AWD van needs the side confirmed first.

An all wheel drive Astro front hub is not one part number. It is three, split across the driver side and passenger side.
Name the side before ordering. Match the number the old part carries rather than guessing from position.
This page covers the 2003-2005 Chevy Astro: 2003, 2004, 2005. Other years live on the main Astro wheel bearing page.
Year by year
2003, 2004 and 2005 share every row on this page. A 2004 Chevy Astro front wheel bearing matches 2003 and 2005 on a 2WD van: 515044. AWD vans use the same three handed listings across all three years.
The rear axle bearing, 513067, does not change across the run either.
2WD versus AWD up front
The Astro’s front end changes with drivetrain, not model year. That is why drivetrain matters more than the calendar here. A 2WD van never uses the AWD listings, and an AWD van never uses 515044.
The rear stays an axle bearing on every configuration. That is a different repair than a wheel hub; see axle bearing versus wheel bearing.
Diagnosing a Chevy Astro wheel bearing
- Listen for a hum that shifts with speed. A worn hub often gets louder as speed climbs. The tone can change again in a turn.
- Check for play at the wheel. With the van safely supported, grab the tire top and bottom and rock it. See how to check a wheel bearing for the full method.
- Confirm the drivetrain first. A 2WD van needs 515044. An AWD van needs the handed listing for the noisy side.
- Rule out tires before condemning the hub. Cupped or unevenly worn tires can mimic a bearing hum; see tire noise or wheel bearing.
- Note which wheel changes the sound in a turn. A bearing that gets louder turning away from the bad side points to that wheel; see wheel bearing noise in a turn.
Common questions
What wheel bearing does a 2004 Chevy Astro need up front?
A 2004 Chevy Astro front wheel bearing is 515044 on a 2WD van. An all wheel drive van uses one of three handed listings instead: 515091, 515092 or 515093.
Is the 2003 Astro front hub the same as 2005?
Yes. The front hub numbers are identical across 2003, 2004 and 2005 for a given drivetrain.
Why are there three numbers for one AWD front end?
The catalogs split the AWD front hub by side instead of printing one universal listing. The driver side and passenger side each carry their own number among the three.
Is the Astro rear a hub assembly or an axle bearing?
It is an axle bearing, part 513067. That is a different kind of repair than a wheel hub.
Do 2WD and AWD Astro vans share any front part?
No. A 2WD van uses 515044 and an AWD van uses the handed listings; the two never overlap.
