The short version
- The 2001 LeSabre wheel bearing is the trap year: first design cars take 513121, second design cars take 513179.
- Before that it is tidy: 513087 for 1992 to 1999 with ABS, 513121 for 2000.
- Rears simplified to 512003 from 2000 on; 1990s cars with ABS use 513062.
- Nearly every number is shared with the Park Avenue.
General Motors changed the front hub design on this car in the middle of 2001 without changing anything a buyer could see. That single decision causes most of the wrong orders on this vehicle.
The mid-2001 design split
A 2001 LeSabre wheel bearing is 513121 if the car was built as a first design, 513179 if second design.
The year on the title cannot answer this. Pull your old hub and match it, or run the VIN at a parts counter before ordering.
From 2002 through 2005 every car takes 513179, and 2000 cars all take 513121. Only 2001 straddles the line.

1991 has its own oddity
The 1991 front is listed by spline count, with 27-spline cars taking the 513016-K kit rather than the later hub.
If you own one of these, count the splines on the old unit before buying anything.
One family of parts across big Buicks
The Park Avenue tracks the LeSabre almost number for number, and the same 513121 and 513179 pair runs through Cadillacs and other GM full-size cars of the era. Searching by the number instead of the model opens up far more listings.
The related LaCrosse that replaced this car has its own page, and the make overview is on the Buick page.
Diagnosing a LeSabre wheel bearing
- Identify the design on any 2001 car before ordering, by old part or VIN.
- Weave at highway speed and note which way the drone follows weight.
- Rock the wheel at twelve and six.
- Watch the dashboard, since a worn hub can trip the ABS light through its sensor.
- Check both sides, as these cars rack up highway miles evenly.
The routine is on the checking page, and the dashboard behavior is on the ABS light page.
Common questions
Which LeSabre wheel bearing fits a 2001?
Either 513121 or 513179 depending on build. Match the old part or run the VIN. The title year cannot tell you.
Are these bolt-on hubs?
Yes, front and rear on the years covered here. No press work.
Can I use Park Avenue listings?
Almost always. The two cars share this hardware year by year.
What about a 1991 car?
Check the spline count first. The 27-spline front takes a kit, not the later hub.
My car has no ABS. Does it matter?
On early 1990s cars yes, the hubs differ. From the late 1990s the listings converge.
Should the sensor come with the hub?
On ABS cars the sensor is part of the assembly, which is exactly why a worn bearing can light the dash. That link is explained on the hub sensor page.
