A highly compact wheel end (A) for an automotive vehicle includes a housing ( 2 ), a hub ( 4 ) having a hollow spindle ( 18 ) that projects into the housing, and an antifriction bearing ( 6 ) located between the housing and the hub spindle. The housing is configured for attachment to a suspension system component (C), whereas the hub has a drive flange ( 14 ) for securement of a road wheel (B) The bearing includes an inboard inner race ( 32 ) that fits around the hub spindle and has a recess ( 40 ) that at least partially receives a formed end ( 26 ) at the end of the spindle. In addition, the wheel end has a coupler ring ( 8 ) that fits into the inboard end of the spindle and is provided with an enlarged end ( 52, 86 ) that projects a short distance from the end of the spindle where it is provided with an external spline ( 54, 88 ) for engagement with a slidable clutch ring ( 66, 90 ).
