The short version
- A 2003 Cadillac CTS wheel bearing is documented by one catalog only: 513186 in front, 512223 in the rear. The fuller parallel listings do not start until 2004.
- From 2004 to 2007, non V cars have two catalog numbers per position. 513186 or 512246 in front, always matched by the old part rather than swapped freely.
- The CTS-V is its own car at both ends from 2004 on. It uses 513197 or HA590077 in front and 512249 or HA590082 in the rear.
- 2003 is the thin year in the catalogs, with only one listing reaching back that far.
Cadillac’s first CTS ran from 2003 to 2007, and the catalogs treat its debut year differently. A 2003 Cadillac CTS wheel bearing has only one documented listing per position. From 2004 on, the picture gets fuller and more complicated at once.

This page covers the 2003-2007 Cadillac CTS: 2003, 2004, 2005, 2006, 2007. Other years live on the main Cadillac CTS wheel bearing page.
CTS-V wheel bearings, front and rear, are only documented from 2004. A 2003 V still matches the non V listing until better information turns up.
From 2004 on, both the regular car and the V carry two parallel numbers per position. Match the number the old part carries rather than picking one at random. 513197 also shows up in listings for another Cadillac model, so order from this car’s own row.
Year by year
2003 is covered by a single listing at each position, 513186 in front and 512223 in the rear. The catalogs do not carry a CTS-V split back this far.
2004 opens up the full picture. Non V cars gain a second front listing, 512246, and the CTS-V gets its own numbers for the first time: 513197 or HA590077 in front, 512249 or HA590082 in the rear.
2005 through 2007 continue that same pattern with no further changes documented.
What changes when the V badge is on the car
The CTS-V is not a trim level as far as wheel bearings go. It is a separate parts list from 2004 forward, and that split carries into the next generation too on the 2008 to 2014 Cadillac CTS wheel bearing page.
Anyone working on a 2003 Cadillac CTS wheel bearing job should also confirm ABS equipment. A bad bearing tripping the ABS warning light shows up early on this platform’s hubs.
Diagnosing a Cadillac CTS wheel bearing
- Confirm CTS-V or standard first. The two share no wheel bearing numbers from 2004 on.
- On a 2003 car, use the single documented listing. There is no parallel number to compare against that early.
- Listen for a speed related growl. See how to check a wheel bearing for the basic routine.
- Check the noise in a turn. Wheel bearing noise on turns often shifts louder toward one side.
- Rule out the tires. Compare tire noise against a bad bearing before condemning the hub.
