Detailed Product Description

The MPA Electrical WH512365 wheel bearing and hub assembly is a new, high-quality component designed to replace worn or damaged hubs on select Lexus and Toyota vehicles. Its 26-spline design ensures a secure connection to the axle shaft, while the trapezoid flange shape with four bolt holes provides a stable mounting surface. The flange diameter measures 5.965 inches with a 2.56-inch offset, matching OEM specifications for proper fitment. This assembly supports an encoder-type ABS system, allowing integration with your vehicle's anti-lock braking without including the sensor itself. The included gasket or seal helps prevent contamination and maintain bearing integrity. With five M12 x 1.5 wheel studs and a 3.42-inch hub pilot diameter, this hub assembly offers precise wheel alignment and secure attachment. Constructed from steel, it provides durability and resistance to wear under normal driving conditions.
