Rear wheel/trailing arm bearing question Options

[SKL1]

Pressed new bearings into the rear trailing arms of the '73 2.0 I'm restoring, and am using OEM 914/6 trailing arms, hubs, etc.

Both bearings pressed in pretty easily after having them in the freezer overnight. When pressing in the hubs, one went in smoothly, though the second one kind of hung up about half way in, and when pushing more, the inner race in the bearings (after the split in the middle) split and the bearing almost came apart. Or I should I say basically did come apart. With the hub pushed in, the whole thing was wobbling, essentially ruining a NEW bearing (IMG:style_emoticons/default/sad.gif)

Any suggestions as to what we might have done wrong, before I attempt to try this again with a NEW bearing (IMG:style_emoticons/default/headbang.gif)

TIA.
