Detailed Description

Part number 103000 is a GSP wheel bearing and hub assembly engineered for rear service on 1991-2002 Saturn SL, SL1, and SL2, plus 1991-1992 Saturn SC, 1993-2002 Saturn SC1 and SC2, 1993-1999 Saturn SW1, and 1993-2001 Saturn SW2. The Gen 3 ball bearing construction supports a compact hub design, while the 4-stud, 100 mm bolt pattern and 57 mm pilot diameter define the mounting interface. This Saturn wheel bearing and hub assembly is a practical OE-style replacement when the original hub shows wear or mounting issues.

This part cross-references SKF BR930053 and Timken 512000 for the same application.

What It Is Used For

• Restoring a worn rear wheel hub assembly.
• Addressing wheel looseness or bearing noise.
• Replacing damaged wheel studs or hub mounting surfaces.
• Correcting fitment issues related to hub wear.

Installation Notes and Tips

Confirm rear fitment by year, model, and hub dimensions before installation. Match the bolt circle diameter, pilot diameter, flange offset, and stud count to the original part. Because ABS is listed as no, verify the vehicles brake and hub configuration before ordering.
