3680-12 Specifications
Application: GM STS AWD | Bore ID: 1.181" (30 mm) | Center to Base: 1.043" | Type: Rubber-isolated center support bearing
The Cadillac STS AWD uses a distinct 1.043" center-to-base height for the propshaft center bearing -- an application-specific dimension that does not round to 1.000" or 1.125". This precision makes the 3680-12 very specific to the STS AWD application and highlights a critical measurement rule: always measure the removed bearing with a digital caliper, never estimate from appearance or round to the nearest standard value.
The STS AWD propshaft routes through a compact tunnel with limited vertical clearance. The 1.043" drop positions the bearing at the exact propshaft centerline for this architecture. GM OEM part numbers in the 12471752 or 88951975 series may apply to the STS AWD; confirm via the GM GMPD catalog using your VIN and drivetrain code before ordering.
