Universal Steer (Front) Wheel Seal 4.848in OD AutoMann - 181.370001A

Part number 181.370001A

Automann lists 181.370001A as an Automann National Type oil seal with a 3.500-inch shaft diameter, 4.848-inch O.D. and 0.925-inch width. Its source distinguishes steer from trailer/pusher/tag axle applications; those application lists are not combined into universal fitment, and National Type is not genuine National identity.
