A drive axle joint seal sock for extending the operation of the joint seal and protecting the joint seal against high heat conditions. The sock comprises an elongate cylindrical housing having an aperture at each end and formed of a heat-resistant material. Clamping structure, such as adjustable clamping rings, extend about each aperture and clamp the sock about the drive axle shaft and the joint, respectively.
