No lubricant on wheel fasteners.  I'm dealing with some wheel issues
on a non-vanagon and was doing a lot of research.  I learned this
along the way.  I have lubed some long ago in the past and not had
anything bad happen, but will not do it again.  Saw a photo of an
alloy wheel cracked where the lubricated fastener reached specified
torque after very much more tighter than without lubricant.  With the
reduced friction, it keeps turning and turning before hitting the
torque value on the wrench.
