SKF BR930081 Wheel Bearing Hub Assembly

SKF BR930081 is an X-Tracker high performance wheel bearing and hub assembly built for front and rear applications on select Cadillac STS and Cadillac CTS models. Its double row angular contact ball bearing design increases load capacity and hub stiffness for more consistent handling and braking under demanding driving conditions.

Key Features

• Double row angular contact ball bearing arrangement for increased bearing capacity
• Hub stiffness improved by 50 percent versus a original tapered bearing hub
• Designed for stable braking and handling performance
• Triangular flange shape with a 5.728 flange diameter
• Brake pilot diameter: 2.781; hub pilot diameter: 3.596; inside diameter: 1.328
• Fits 2003-2007 Cadillac CTS, rear
• Fits 2005-2011 Cadillac STS, front, X-Tracker; w/o HD Package
• Fits 2005-2011 Cadillac STS, rear, X-Tracker; 5 Stud Hub

Detailed Description

SKF BR930081 is engineered as a wheel bearing and hub assembly for Cadillac CTS and Cadillac STS fitments that require precise hub support and consistent rotational control. The X-Tracker design uses a double row angular contact ball bearing layout to increase capacity while improving stiffness, which helps maintain braking feel and steering response in demanding service. This part cross-references Monroe Shocks & Struts (e.g., 25693148) for the same application. SKF BR930081 is a direct-fit option for 2003-2007 Cadillac CTS rear applications and 2005-2011 Cadillac STS front and rear applications listed above.

Common Problems This Part Can Address

• Wheel bearing noise such as humming, growling, or rumbling
• Excessive hub play or looseness at the wheel
• Uneven braking feel caused by worn hub support
• Vibration or instability from a deteriorated bearing assembly
• Reduced steering precision from worn rear or front hub components

Installation Notes and Tips

Confirm the vehicle position and notes before ordering: 2005-2011 Cadillac STS front applications require the X-Tracker version without the HD Package, while rear applications require the 5 stud hub configuration. Verify flange shape, pilot diameters, and mounting dimensions against the removed part before installation. Clean the mounting surface and inspect adjacent suspension and brake components for wear that could affect hub performance.

Quality Assurance

SKF has supplied engineered drivetrain and wheel-end components for more than 100 years, and this hub assembly is manufactured to SKF quality standards for long service life and safety.
