I tested my VC's resistance to turning movment today.  Jacked up one
front wheel, put torque wrench one lug nut, pointing directly at the
axis of rotation and turned--wheel would _START_ to rotate at 25 lbs
torque.
Would be interested in hearing other lister's experience.  Will be
replacing a different VC with a rebuilt one in another syncro I own.
Will post results of that test in a couple of weeks. HTH  Joel
