The short version
- The 2006 Cadillac STS wheel bearing lineup runs the full 2005 to 2011 span. AWD fronts use 513238, RWD fronts split into 513197 (6 stud) or 512246 (5 stud), and rears split into 512243 (6 stud) or 512223 (5 stud).
- Stud count decides the RWD numbers on both ends. Count studs before ordering rather than guessing from the year.
- 2008 to 2010 AWD cars built with Brembo brakes fall outside the 513238 listing. The catalogs carry no separate number for that combination.
- The AWD front row stops at 2010. The RWD and rear rows run through 2011.
This page covers the 2005 through 2011 Cadillac STS, a single production run with no separate generation pages to sort through. The 2006 Cadillac STS wheel bearing sits in the middle of that run. Its number is picked the same way as any other year, by drivetrain first and stud count second.
The core numbers
A 2006 Cadillac STS wheel bearing order comes down to two questions. Is the car AWD or RWD, and does the hub carry 5 studs or 6.
AWD fronts are one listing, 513238, with an exception for Brembo brakes from 2008 to 2010. RWD fronts and both rear positions split into a 5 stud group and a 6 stud group. The two groups never cross.

This page covers the 2005-2011 Cadillac STS: 2005, 2006, 2007, 2008, 2009, 2010, 2011. Other years live on the main STS wheel bearing page.
Count the wheel studs before ordering a front or rear hub for any RWD STS. The lineup splits into a 6 stud group, 513197 front and 512243 rear, and a 5 stud group, 512246 front and 512223 rear. The wrong stud count will not bolt on.
AWD cars from 2008 to 2010 with Brembo brakes fall outside the 513238 listing entirely. Match the number the old part carries or run the VIN.
Year by year
2005 to 2007: the Brembo split has not started yet. Every AWD car in these years uses 513238 without exception, and RWD fronts and rears already follow the stud count split. The 2006 Cadillac STS wheel bearing question resolves the same way as 2005 and 2007.
2008 to 2010: AWD fronts still use 513238, unless the car carries Brembo brakes. In that case the catalogs stop short, so match the part to the old one or confirm by VIN. RWD fronts and rears keep following the stud count split through this stretch.
2011: the AWD front row ends at 2010, so this year runs on the RWD and rear rows only. Front is 513197 or 512246 by stud count. Rear is 512243 or 512223 by the same rule.
Drivetrain and stud count across the platform
The STS shared its front hub logic with other Cadillac sedans that offered both AWD and RWD. That is why the split by drive type matters more here than the model year. Stud count is a separate variable, tied to the wheel and brake package rather than the calendar.
Diagnosing a Cadillac STS wheel bearing
- Note where the noise changes. A worn hub usually gets louder in a turn that loads the bad side. See turning noise notes for the pattern.
- Rule out the tires first. Cupped or unevenly worn tires can hum in a way that mimics a bearing at highway speed. See tire noise or wheel bearing.
- Jack up each corner and check for play. Grip the tire at 12 and 6 o’clock and rock it. A worn hub moves in a way a tire or ball joint problem will not.
- Confirm drivetrain before ordering anything. AWD and RWD STS models use different front listings.
- Count the studs on the hub face. That number decides between the 513197/512243 pair and the 512246/512223 pair.
Common questions
What wheel bearing does a 2006 Cadillac STS use?
A 2006 Cadillac STS wheel bearing order depends on drivetrain and stud count. AWD front is 513238, RWD front is 513197 (6 stud) or 512246 (5 stud). The rear is 512243 (6 stud) or 512223 (5 stud).
What wheel bearing fits a 2011 Cadillac STS?
2011 falls after the AWD front row ends, so this year runs on the RWD and rear rows only. Front is 513197 or 512246 by stud count. Rear is 512243 or 512223 by the same split.
Why doesn’t the AWD front number cover my 2009 STS with Brembo brakes?
The 513238 listing excludes 2008 to 2010 AWD cars built with Brembo brakes. The catalogs carry no separate number for that combination. Match the number the old part carries or confirm the fitment by VIN.
How do I know if my STS is 5 stud or 6 stud?
Count the studs on the hub face with the wheel off. That single count decides between the 513197/512243 pair and the 512246/512223 pair.
Are the STS front and rear bearings press in units or bolt on hubs?
Every listing on this page is a bolt on hub assembly, front and rear, AWD and RWD alike. None of these positions use a separate press in bearing and seal.
