The short version
- The 1999 to 2004 Oldsmobile Alero, including a 2003 Oldsmobile Alero wheel bearing job, uses one front hub number and one rear hub number for the entire run.
- Front hub bearing is 513137 and rear hub bearing is 512152, both bolt on assemblies, no trim splits.
- Six model years, one engine choice or another, and the numbers never move.
- The only real risk is being talked into a trim specific part that the catalogs do not actually list.
From 1999 to 2004, Oldsmobile built the Alero on one hub setup and left it alone. A 2003 Oldsmobile Alero wheel bearing order is as simple as this platform gets. Front and rear each carry a single number for all six years.
The Alero wheel bearing numbers at a glance
Both ends use bolt on hub bearing assemblies, not a press in ball design.
Every Alero built from 1999 through 2004 shares the same two numbers regardless of trim or engine.

This page covers the 1999-2004 Oldsmobile Alero: 1999, 2000, 2001, 2002, 2003, 2004. Other years live on the main Alero wheel bearing page.
This is the easy case: one number per end covers the whole generation. The real risk is overthinking it, or letting a counter person upsell a trim specific part that the catalogs never list in the first place.
A 2003 Oldsmobile Alero wheel bearing quote that names a different part number for a GLS or an SE is worth a second look before paying for it.
Year by year
Nothing splits this generation into eras. Every year from 1999 through 2004 uses 513137 up front and 512152 in back. A base coupe, a sedan, and a GLS all draw from the same two rows.
A 2003 Oldsmobile Alero wheel bearing order needs nothing extra beyond those two numbers, and neither does any other year in the run.
One hub setup for the whole generation
The Alero shared its era with other GM compacts, but this page only covers what the catalogs list for the Alero itself. Both ends are listed as hub bearings, one number each, for the whole run.
Because coverage is this uniform, most of the diagnostic work is just confirming which corner is actually bad before ordering.
Diagnosing an Oldsmobile Alero wheel bearing
- Note where the sound is loudest. A bearing hum usually tracks with road speed, not engine RPM.
- Listen through turns. A sound that grows in one direction and fades in the other points at a bearing over a tire.
- Jack up each corner. Rock the wheel at 12 and 6 for play, then check 3 and 9 for tie rod slack.
- Watch the dash. A wheel bearing failure can bring on an ABS light before any noise shows up.
- Confirm with a full walkthrough. A complete diagnostic guide separates bearing noise from suspension noise.
Common questions
What is the 2003 Oldsmobile Alero wheel bearing part number?
Front is 513137 and rear is 512152. Those two numbers cover the 2003 model and every other year from 1999 to 2004.
Does the 1999 Alero use a different wheel bearing than the 2004?
No. The 1999 and the 2004 use the identical front and rear numbers, with nothing changed in between.
Is the Alero wheel bearing a bolt on hub or a press in bearing?
Bolt on. Both the front and rear are complete hub bearing assemblies, so there is no press work needed.
Does trim level change the Alero wheel bearing part number?
No. The catalogs list one front and one rear number for every trim across all six years.
What causes wheel bearing noise on an Alero to sound like tire noise?
Both produce a hum that rises with speed. Checking how the sound behaves in a turn is the fastest way to tell them apart.
