ABSTRACT OF THE DISCLOSURE An internal seal is provided for a universal joint, which seal is more effective in retaining lubricant and in preventing the ingress of water and contaminants. More specifically, the universal joint includes a cross having a body and trunnions extending therefrom. Each trunnion is received in a bearing cup having an open end with an internal annular shoulder near the open end. The universal joint seal comprises a resilient sealing member having at least two inner circular lips which engage the trunnion near the cross body and at least two outer circular lips which engage the internal surface of the bearing cup between the open end and the annular shoulder. The sealing member further includes an additional lip which engages the annular shoulder and a spaced additional lip or ridge which engages the body of the cross adjacent trunnion. The latter two lips serve to position the sealing member with respect to the cross and bearing cup with the sealing member being substan- tially enclosed by the bearing cup, which minimizes the possi- bility of damage to the sealing member. The internal universal joint seal provides a total of at least three seals between the sealing member and the cross and also between the sealing member and the cup to contain lubricant in the cup and to prevent the ingress of water and contaminant. In one form, the sealing member also has a longer lip which extends over upper ends of needle bearings located between the trunnion and cup to aid in retaining the needle bearings in place when the cup is separated from the trunnion.
