Drive Axle Breather Check

4700 mm 35.03.001

Axle breathers must NOT be clogged. Whenever the axle lubricant level is checked, be sure the axle breather is also checked. If operating under adverse conditions, check the breathers more often. If the breather is damaged or plugged, have it cleaned or replaced. For the location of the breather on Detroit axles, see Fig. ; for Meritor axles, see Fig. ; and for Dana Spicer axles, see Fig..
