Why King Subaru XP flange bearings do not have locating lugs?
In order to prevent a oil leak path, therefore lowering oil pressure, the lug has been removed from the King thrust bearings for the Subaru EJ, FA/FB engines. Symmetrical thrust bearings do not need a locating lug for exact placement because the flanges do this automatically.
