Abstract: A universal joint seal is disclosed for sealingly engaging the trunnion and the bearing cup of a Cardan type universal joint cross member. The seal has three sealing lips, one of which sealingly engages the spaced apart bearing surfaces of the trunnion and the bearing cup. That one sealing lip, in addition, resiliently engages the ends of the needle bearings contained within the cup to prevent their accidental dislocation.
