So I took the tires and brake drums off and the play at the axle flange is clearer;
The passenger side end-play (in/out) is maybe 1/16", and there is some play in the bearing, less than 1/32" I'd say. The gap where the drive shaft enters the bearing plate is dry and clean.
The driver's side is very different. Same end-play, but much more play fore/aft and up/down at the bearing, nearly 1/16". The gap where the shaft enters the bearing plate is wet with oil, not dripping exactly but close.
I checked the oil in the diff case and it is both clean and full.
So I will now read the FSM about axle bearing replacements, they may have tolerances for the bearing play, but I bet it's less than my 1/32" to 1/16" .
I appreciate both of your opinions on bearing type John and Mike, thanks for keeping it respectful, I'll replace both sides with the type that works for me.
I'll check for comments and get back here with any issues.
