My experience was:
1 fitting lying in the cup
1 fitting so loose there were one one thread holding it in.
No grease at all in all four hubs (other than assembly grease in the pre-packed bearings)
I used 1 full sized tube of grease the first time I greased them.
I think the dufus at the factory did not know they were the new "flow through" spindles. Someone must have just told him to screw on the zerk fittings and not knowing why he was doing it, just put them on hand tight.
My right front hub ran cool for the first time after I filled the hubs correctly.
My mistake was assuming:
1) The factory serviced the trailer prior to shipment
2) The dealer actually LOOKED that the hubs had been serviced as part of the dealer's acceptance inspection (I know it was "free" but jeeze they could have actually DONE one).
