Second try as the reprevious one came to my account with a body of

        Well, there is another not-so-pretty test... Jack up one of the rear
wheels under the swing arm with a trolley floor jack. Put a small log in
front of one of one of the front wheels. Try to drive over it very slowly in
low gear. If you make, you VC works, if not, it doesn't ;)
        Like I said, it's the not-so-pretty test and you could screw up the
rear end - there is a good possibly that the trolley jack could get stuck in
a crack in whatever surface you are preforming the test. If you don't get the
jack in line with the direction of motion, it may slip out from under the
rear wheel and damage something in the area (like a drive shaft or a brake
line). But it is the only test I have seen that will simulate the back end
losing traction (well, I suppose it doesn't really simulate it) and the log
provides resistance to verify that the VC itself is locking and that the
forward or reverse motion is not being transmitted through the VCs seals
(the torque at which these things slip is in the archives I believe - I
could be confusing this with the torque needed to overcome the resistance
introduced by the final drive seals in both the front and rear diffs when
performing the front tire rotation test). It was suggested by another list
member who name escapes me as I wouldn't have thought of doing this.
