Per page 3-60 in the 1999 Mopar service manual, here's the "Trak-Lok Test:"
After cautions about raising both rear wheels when turning with engine,
yada, yada, yada, it states that you can test the diff w/o removing from
vehicle, here goes...
1. place blocks under both front wheels.
2. raise ONE rear wheel off ground.
3. engine off, trans in neutral, parking brake off, no dragging of brakes.
4. remove wheel and attach tool #6790 which is just an attachment
allowing a torque wrench to attach to the hub via three lug nuts (to avoid
breaking one if used on just one and to center torque wrench in center of
hub for accuracy).
5. use torque wrench to rotate wheel.
6. If rotating torque is less than 22Nm/30 ft.lbs. or more than
271Nm/200 ft. lbs. on either wheel, the unit should be serviced.
Hope this helps.
