ABSTRACT:
A seal is provided on a slinger for a pinion shaft in an axle housing. The seal provides sealing contact at a location between the bearing cage and the slinger. The slinger prevents relatively large dirt, stones, and debris particles from reaching an inner oil seal. The seal on the slinger prevents smaller particles from reaching the oil seal. Several embodiments of the seal are disclosed.
