This page covers the 1999-2005 Pontiac Grand Am: 1999, 2000, 2001, 2002, 2003, 2004, 2005. Other years live on the main Grand Am wheel bearing page.
GT models in 1999 and 2000 take 512152 in the rear. Every other trim in those two years takes 512003 instead. From 2001 that split disappears, so check the trim badge only on the earliest cars.
Year by year
1999 and 2000 split the rear by trim. GT models take 512152, and every other trim takes 512003. The front, 513137, is already the same number used all the way through 2005.
2001 through 2005 settle on one rear number, 512152, for every trim. A 2004 Pontiac Grand Am wheel bearing, like every year in this stretch, needs no trim check at all.
Earlier Grand Ams are a different lookup
Grand Ams built through 1998 use entirely different front and rear numbers. Those earlier years are not covered on this page.
This page only applies to 1999 through 2005, the span where 513137 and the rear numbers above are documented.
Diagnosing a 1999-2005 Pontiac Grand Am wheel bearing
- Confirm the trim on early cars. On a 1999 or 2000 model, check whether the car is a GT before ordering the rear.
- 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.
