An axle assembly having a constant shaft disposed at least partially through a bearing hub assembly. The constant shaft defines a fluid conduit therethrough. A steering knuckle is disposed at least partially about the constant shaft. The axle assembly may include a bearing spacer disposed about the constant shaft, the bearing spacer being disposed at least partially axially between the bearing hub assembly and the steering knuckle. Additionally, a first rotary seal and a second rotary seal may be disposed radially between the bearing spacer and the constant shaft. The first and second rotary seals may at least partially define a fluid chamber in fluid communication with the constant shaft fluid conduit. Further, a port may be disposed through the bearing spacer, wherein the port is in fluid communication with the fluid chamber.
