I thought bearing but brake drum would have been letting you know, certainly looks like a bent axle as I now see its both wheels shown..... if it is a new axle will be needed along with U bolts for springs ...................... be most interesting to see some pics of underneath.
Only way to find out is to lift it as stated above..........................
When ever you jack up an axle always put a jack stand under the draw bar or hook onto the tug as the jockey can move and the van fall off the jack.
