Absence of the three wheel mounting studs and positioning the hub in this direction allows the bearing splitter to be installed behind the flange in the next step.
Install the Bearing Splitter (2), Special Tool 1130, between the hub and the bearing retainer plate as shown. Hand tighten the nuts to hold bearing splitter in place on knuckle.
