July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Test

1. Wipe oil out of axle housing and carefully clean each tooth of the ring gear.
2. Apply gear marking compound sparingly to all ring gear teeth using a medium stiff brush.
3. Apply a load until a torque of 54-68 Nm (40-50 ft. lbs.) is required to turn the pinion.

A test made without loading the gears will not give a satisfactory pattern. Turn the companion flange with a wrench so that the ring. gear rotates one full revolution. Then reverse the rotation so that the ring gear rotates one revolution in the opposite direction. Excessive turning of the ring gear is not recommended.








4. Observe the pattern on the ring gear teeth and compare with the images shown.
