Checking the Axle Breather

sb mm 35.04.001

The axle housing breather must remain unobstructed. Whenever the axle lubricant level is checked, also check that the axle breather is open. Check more often under poor operating conditions. If the breather is plugged, clean or replace it as needed.

For component locations on a Detroit axle, see Fig.. Meritor axles are shown in Fig. and see Fig..
