Here's the specs for the Dana 60 rear axle for the van.
Dana 60 van axle specs.jpg
The hub nut is a ratcheting affair on the Sterling axles used on the SRW pickups. They use a "click" method of adjustment, but the Dana axle is apparently different. Couldn't find the actual hub removal instructions in the service CD for the van.
On both axles, the wheel bearings get packed with grease, but are actually lubed by the axle lubricant, with the grease just for initial lubrication.
Hope that helps.
