Swivel leak but no play?

Whereabouts are you located. It doesn't say on your profile.

I'm in goudhurst in Kent, i've got an exploded diagram of the hub now and can see what you mean
I'm going to buy the hub tool anyway so I can have a decent look at the condition of the various bearings and seals etc properly. So i'll just replace the king pin bearings and shaft seal, but have a look at the wheel bearings and other seals.

Cheers!

By the way, what oil type goes in the axles?
