The short version
- A 2003 Buick LeSabre wheel bearing is 513179 in front, the same number used from 2002 through 2005.
- 2000 and part of 2001 use an older front number, 513121, before a mid cycle design change.
- The rear number never changes across this generation: 512003 covers every LeSabre from 2000 to 2005.
- 2001 is a split year with two front designs on record, so match the number the old part carries.
From 2000 to 2005, Buick built the LeSabre around two different front wheel bearing designs. A 2003 Buick LeSabre wheel bearing is the newer number, 513179, but some 2001 cars still carry the older part. The rear stayed one number for the whole run.

This page covers the 2000-2005 Buick LeSabre: 2000, 2001, 2002, 2003, 2004, 2005. Other years live on the main LeSabre wheel bearing page.
Some 2001 LeSabres carry the older front, 513121. Others carry the newer front, 513179. The catalogs list both for the same model year, so match the number the old part carries rather than guessing by date.
Year by year
2000 LeSabres take the older front number, 513121. The rear, 512003, is already the same part used all the way through 2005.
2001 is the split year. Some cars still carry the first design, 513121, and others carry the new front, 513179. Match the number the old part carries before ordering.
2002 through 2005 settle on the newer front. A 2003 Buick LeSabre wheel bearing, along with every year through 2005, is 513179. The rear stays 512003 for these four years too.
Why 2001 is the pivot year
The front design changed mid cycle in 2001, not at a clean model year boundary. Matching the old part matters more than trusting the calendar here.
Earlier LeSabres, from 1992 to 1999, use entirely different front and rear numbers. Those years are not covered on this page.
Diagnosing a 2000-2005 Buick LeSabre wheel bearing
- Identify the front design first. A 2001 LeSabre could carry either 513121 or 513179, so check the old part before ordering a replacement.
- Listen for the noise pattern. A worn bearing usually hums or growls and gets louder with speed. Noise that shifts in turns often points at the bearing over other suspects.
- Rule out the tires first. Cupped or unevenly worn tires can mimic a bearing hum. Separating tire noise from bearing noise saves an unnecessary parts order.
- Check for play and roughness. With the wheel off the ground, rock it at 12 and 6 o’clock, then spin it by hand. A full bearing check walkthrough covers both tests.
- Watch for a dash light. A failing hub can also trip an ABS or traction light. How a bad bearing sets off the ABS light explains why.
Common questions
What wheel bearing does a 2003 Buick LeSabre use?
A 2003 Buick LeSabre wheel bearing is 513179 in front and 512003 in the rear. Both numbers hold from 2002 through 2005.
What wheel bearing does a 2000 LeSabre use?
A 2000 LeSabre uses 513121 in front and 512003 in the rear. The front number changed the following year, mid cycle.
Why do some 2001 LeSabres use a different front number?
Buick changed the front design partway through the 2001 model year. The catalogs record both 513121 and 513179 for that year, so the old part decides which one fits.
Do older LeSabres use these same numbers?
No. LeSabres from 1992 to 1999 use different front and rear numbers, and those are not listed on this page.
Does the rear wheel bearing ever change on this generation?
No. The rear number, 512003, stays the same for every LeSabre from 2000 through 2005, regardless of the front design.
