DIFFERENTIAL ADJUSTMENT
While holding rear wheels with your hands, use your right thumb
and index finger to try and rotate the spur gear. The spur gear
should be very difficult to rotate. If you can rotate it easily, then
tighten the #4185 11/32" nut at the end of the axle, a little at a
time, until the spur gear is difficult to rotate.
