hola,
 I've just noticed that when the rear wheels of the van are off the ground they've got maybe 1/16" or 1/8" of play at the outer edge - like the wheel bearings are loose. They don't make any noise, though. Is this something I should worry about? I've got an extra set of bearings, but would rather not have to deal with it at this point, if I don't have to. 

Thanks,
 Jeff
