A wheel spindle flange (and the like) has stud holes with soft surface hardness formed therein which permit non-rotational splines, studs and the like to be press-fitted therein with minimal press force at a centered press zone established between intentionally formed and dimensioned counterbores within the flange to minimize flange distortion and lateral run out of the spindle.

Method and apparatus for wheel spindles and the like with improved LRO

A wheel bearing assembly for supporting a wheel is provided. The assembly includes a spindle defining a rotational axis and a support member for supporting the spindle. A wheel hub has a flange for securing the wheel thereto. The wheel hub is supported on the spindle and is rotatable about the rotational axis. A bearing assembly has first and second bearing members in spaced relationship from one another with a plurality of bearings interposed between the bearing members to permit relative rotation between the bearing members about the rotational axis. The first bearing member is arranged adjacent to the spindle and the second bearing member is arranged adjacent to either the wheel hub or the support member. An inner surface of the first bearing member has an annular counterbore. The spindle is deformed into the counterbore to axially secure the first bearing member to the spindle and prevent relative rotation between the spindle and the first bearing member about the rotational axis. This minimizes both axial bearing length and spindle member distortion.
