Block the front tires, put the tranny in neutral, put the tcase in 2wd, jack 1 rear tire off the ground (both tires, if it has a spool or is welded in the rear), spin the rear tire exactly 2 revolutions while counting the revolutions of the rear driveshaft.
A little over 4 1/4 revs=4.30s.
A little over 4 1/2 revs=4.62s.
A little over 4 3/4 revs=4.88s.
A little over 5 revs=5.12s.
A little over 5 1/4 revs=5.38s.
A little over 5 1/2 revs=5.62s
A little over 5 3/4 revs=5.83s
