Detailed Product Description

The Timken SP500702 wheel bearing and hub assembly is a critical component in the driveline and axles category, specifically designed for driven axles on select Nissan and INFINITI models. This assembly features a 32-spline interface that ensures a secure connection to the axle shaft, while the 6 wheel studs provide a stable mounting surface for the wheel. The flange includes 4 bolt holes arranged on a 5.5-inch bolt circle diameter, matching factory specifications for the Armada, Pathfinder Armada, and QX56.

Precision measurements such as the 3.059-inch wheel pilot diameter and 3.230-inch brake pilot diameter ensure proper alignment of wheels and brake components, reducing vibration and wear. The hub pilot diameter of 3.500 inches centers the hub accurately on the axle, contributing to smooth rotation and extended bearing life. The flange diameter and offset are engineered to maintain correct wheel positioning relative to the suspension and brake system.
