Detailed Product Description

The Timken 513061 wheel bearing and hub assembly is designed specifically for driven axle applications in Chevrolet Blazer, GMC Jimmy, Oldsmobile Bravada, and related models such as the S10, S10 Blazer, S15 Jimmy, and Sonoma. This assembly features a 27-spline shaft interface that ensures a secure connection to the drivetrain, while the 3-bolt flange design provides a stable mounting surface. The 5-wheel stud configuration supports standard wheel attachment, maintaining proper wheel alignment and safety.

Precision in pilot diameters is critical for proper fitment: the wheel pilot diameter measures 2.760 inches (70.10 mm), and the brake pilot diameter is 2.780 inches (70.60 mm), both ensuring compatibility with wheel and brake components. The hub pilot diameter of 3.209 inches (81.50 mm) centers the hub accurately on the axle shaft. Flange offset and diameter measurements are engineered to maintain correct wheel positioning relative to the suspension and brake system.
