ABSTRACT OF THE DISCLOSURE A universal joint seal is provided for a universal joint, which seal is more effective in retaining lubricant and in pre- venting the ingress of water and contaminants, particularly when engaging surfaces which tend to be rough. In a specific form, the universal joint includes a cross having a body and trunnions extending therefrom with an annular shoulder and an adjacent surface of circular cross section at the juncture of said body and each of said trunnions. The bearing cup has an open end which receives the trunnion and can have an annular groove adjacent the open end. The universal joint seal comprises a resilient sealing member having at least two circular lips which engage the annular shoulder of the cross and at least one addi- tional lip which engages the adjacent surface of the cross. The sealing member also has at least one lip which engages the open end of the cup and additional lips which engage the groove portion of the cup. Thus, at least three seals are provided between the seal and the cross and between the seal and the cup to contain lubricant in the cup and to prevent the ingress of water and con- taminants.
