1. Position dial indicator holder with dial indicator on axle housing so that probe of dial indicator is perpendicular to tooth flank.
2. Check the gear backlash by moving the ring gear to and fro.

   This procedure should be repeated on at least 4 positions on the circumference of the ring gear.

   The gear backlash is changed by replacing the shims between the axle housing and bearing. If a thinner shim is installed on one side, then a shim which is thicker to the same extent must be installed on the opposite side, in order to retain the bearing preload.
