Rear wheel bearings on front wheel drive vans are much like front wheel bearings before front wheel drive.
You have an inner and outer bearing with a nut and lock washer.
After the bearings are packed with grease, you tighten down the axle nut until snug then back it off a notch. Then put the lock washer or lock ring on. Some have a cotter pin to hold the nut in place.
The wheel should spin with no drag from the bearings.

There is a little difference between the front and rear. The days of packing wheel bearing is almost over. The front bearing you have to pull the hub and change to bearing. The rear wheel you have to change out the hub bearing and all. The front is a sealed bearing and not serviceable. Please rate my answer so I am rewarded points for it.

A Front Wheel Drive Vehicle Can Have Two Types Of Rear Wheel Bearings: Serviceable Bearings, Or Nonserviceable, Sealed Bearings. When Sealed Bearings Fail, The Bolts Holding The Bearing And Hub To The Axel Or Control Arm Must Be Removed. When Installing The New Bearing Assembly, Torque The Bolts To Specifications.Some Manufacturers require The Use Of New Fasteners When Rear Bearings And Hubs Are Replaced.

When A Serviceable Wheel Bearing Is Used, The Bearing Can Be Disassembled And Packed With Grease.It Is Serviced Like A Front Wheel Bearing On A Rear-wheel-Drive-Car.

You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.
