# Wheel bearing assemblies and vehicles

## Abstract

A wheel bearing assembly is provided. The wheel bearing assembly includes an outer ring, a wheel hub rotating relative to the outer ring, the wheel hub including a hub flange, an inboard surface of the hub flange facing an outboard surface of the outer ring and spaced a gap apart from the outboard surface of the outer ring in an axial direction, a plurality of rolling elements rotatably coupling the outer ring and the wheel hub, a first spacer disposed between the inboard surface of the hub flange and the outboard surface of the outer ring, and a second spacer disposed between the first spacer and the outboard surface of the outer ring. At least a portion of the first spacer and at least a portion of the second spacer are disposed in the gap.
