Jack up one rear wheel [chalk the other one well] put the car in top gear
and use the starting handle to bring the engine to top dead center. Watch
the timing marks. Mark the bottom center of the tire while holding the wheel
back against the transmission backlash. Turn the engine over two complete
turns to exactly T.D.C. again and holding the wheel back against the
backlash once more, see how far the wheel has rotated. If you have a 3.89:1
diff. the wheel should have done just over one complete turn and if you have
a 4.22:1 diff it should have done less than one turn.
Hope this helps
Russ
