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.
