Detailed Product Description

The Timken HA590165 wheel bearing and hub assembly is a critical component in the driveline and axle system, specifically designed for driven axles on compatible Lexus, Scion, and Toyota vehicles. This assembly features a 26-spline interface that ensures a secure connection to the axle shaft, while the 5 wheel studs provide a stable mounting surface for the wheel. The flange includes 4 bolt holes arranged on a 114.3 mm bolt circle diameter, matching factory specifications for proper installation.

Precision measurements such as the 60.00 mm wheel pilot diameter and 62.00 mm brake pilot diameter help maintain correct wheel and brake rotor alignment, reducing vibration and wear. The 90.00 mm hub pilot diameter centers the hub assembly accurately on the axle, and the 47.50 mm flange offset ensures the wheel sits in the correct position relative to the suspension and brake components.
