Side Diff Hub Bolt Walkabout

["Mark Gehlhausen" <Gehl@sphinx.crane.navy.mil>]

Paul et al,
These bolts, as I remember are socket cap screws?  Mine always would 
work loose due to vibration.  I never found any factory gasket at that
face, so out came the read end oil and the bolts loosened to the 
point of falling out.  Might this be your scenario too?  Mark
