Thanks J-Mech,
I've changed more than a dozen wheel bearings on cars and trucks, but they usually have a snap ring. This casing doesn't, and I just want to be sure I'm pressing from the correct spot. I don't have a camera to send a pic, but the casing has a large flange on one side with a ring that protrudes equally on both sides. Do i press from the side with the ribs or the other side? Also, exactly what portion are I pressing - the inner bearing part or the outer protruding ring?
Sorry for the long winded reply, but I gotta get this right

Cheers,
Jeff
