Stop in for a cup of coffee

Could use some help on the Heep's drivetrain.
There's no spec in the FSM, but Timken says that .021" axle movement is OK. Large AMC 20, no adjusterment.
Left side measured .014 and the right .018"
Pull 'em and get new bearings on them? Right brake shows something is seeped. It's not on the lining but could be axle grease?

Diff itself looked really nice. Didn't seem to be any play to speak of. Not that I know what I'm doing here. Just tried to move the unit with a pry bar.

That reminds me, I gotta pull my dana 60 back apart. I forgot to put the spider gear shims in when I rebuilt it. :BangHead::BangHead::BangHead::BangHead::BangHead:
