Rear wheel play 12/6 no play 3/9 - bearing?
What's to check?
Read about the oval bearing housing from smacking on the nut what a 12-6 and a 3-9 caliper measurement confirm this?

I would hope the bearing would be the weak part and wear first, well before the casting. I say you have to pull the bearings and do a measure with a nice caliper before installing new bearings. My guess is the outer bearing will be worn. I changed my bearings a few years back and had this exact issue and bearings fixed it for me. They are tricky to install, and there are many threads on how to do it. I have a huge 3/4" snap on torque wrench for the 46mm nut so I have no experience hitting the axle nut with a huge hammer and the empi tool.
Bearing housings are available now if you do have the worst case scenario. Good luck.

You want a breaker bar to remove this, not a torque wrench

If you can take it out for a drive and check the bearing play again when it's still warm, this will give you a better idea of their condition. The axle bearings on these vans are designated as C3 Clearance Bearings, which means that they have 'Greater Than Normal' clearance between the races than you'd find in a standard bearing, to account for thermal expansion as a result of the bearing getting hot through use. So, you should expect to see some play when the bearings are cold.

I should have elaborated, I have the snap-on detachable head and I have the really long breaker bar attachment for removal, yes. I only torque during reassembly.

Yeah, but I'd expect even play all around when cold... What about the difference in 12/6 vs 3/9

Absolutely - I wouldn't rule that out, but a lot of owners, and a fair number of mechanics, don't realise that the bearings are designed to have some play in when cold, and so it's worth reiterating the need to check what they're like when warm before making a decision to replace.

They tend to wear vertically as they carry the load.

Ok, how do I test that and what ever else is testable? Is there a bearing/hub testing FAQ I missed? (I know there are many threads on bearings/hubs but none of them I remember having testing procedures.)
Got it off!
There was 12/6 play and 6/3 firmness with -
the wheel on
on the drum with the wheel off
with the drum off
on the axle stub with the spindle?/lug stud carrier

"pull bearing" - inside or outside (or both)?
any tricks to keep alignment (12/6) on it coming out or just mark it some way?
