Abstract
A wheel end assembly is provided which facilitates maintenance of the wheel end assembly, and further provides a more secure bearing housing. The spindle is caused to rotate with the drive axle, and is in turn connected to drive a wheel hub. In other features, a housing mounts a bearing cup structure which surrounds the spindle, and has a piloting land for positioning a brake torque plate or a spider, along with the bearing cup. A tone wheel is sandwiched between two nuts, and is caused to rotate with the spindle. The tone wheel includes a tab extending into an opening on the washer such that the washer rotates with the tone wheel. The overall assembly facilitates maintenance and assembly, and provides a more secure environment for the bearing structure.
