An axle seal is presented. The axle seal is disposed about an automotive axle at the automotive differential to prevent leakage of lubricant from the differential. The axle seal comprises a rigid cylindrical body member having outer grooves receptive to o-ring seals to provide a seal between the differential and the body member which is mounted within an opening of the differential. The axle is attached to the differential and passes through an opening in the body member. The body member is chamfered at the opening to direct the axle to the center line during assembly. A step defining a recessed portion is formed within the opening of the body member where inner seals are disposed. The inner seals provide a seal between the axle and the body member and allow significant angular displacement of the axle from the center line without compromising the integrity of the seal between the body member and the axle or between the body member and the differential. The inner seals comprise two spaced apart seals bonded to a sleeve disposed in the recessed portion of the body member. Each seal tapers in thickness from the body member to a central opening, this opening being smaller in diameter than the axle passing therethrough to provide the necessary sealing tension.
