 Let me see if I under stand this "sure Grip" thingy... The right rear wheel
is the "power wheel" and the left rear only "locks" when the right side
slips. Correct? So if this is true, why would the left side "lock" under
this condition?? >>

With the sure-grip in place, it tries to make both wheels turn at the same
speed (of course it is not 100% effective at doing this). An extreme case of
this would be a "spool" rear end, where both axles are truly locked together.
 When going around a turn, something has to give. Theorhetically, the inside
wheel would lift (hop) and spin in a tigt turn. It is also possible that the
outside wheel is hopping slightly, and is also slipping against the pavement.
 A good way to test for proper operation is to make a tight turn in reverse
(the truck moving backwards). This creates the maximum difference in speed
of the rear wheels.

I agree that something doesn't seem quite right with your particular
sure-grip. When mine was new, I could hear some clutch chatter in the rear
end, and occasionally the inside rear tire would hop a little, but it never
spun the outside tire.
