35–01 Axle Lubricant and Filter
Change, and Magnetic
Strainer Cleaning
(synthetic lubricant)
CAUTION
Failure to change the axle lubricant at more fre-
quent intervals, when adverse operating condi-
tions require, could result in axle damage.
NOTE: Axle lubricant change intervals are ex-
tended to 500,000 miles (800 000 km) on ve-
hicles equipped with a Meritor RT40–145P or
RT46–160P rear axle.
Dana Spicer
Dana Spicer does not recommend the use of friction
modifiers in any of their rear axles. Friction modifiers
should be used in Dana Spicer rear axles only if a
slip-stick condition is found, as described in the ve-
hicle driver’s manual. If you are experiencing a prob-
lem with a Dana Spicer rear axle, see Group 35 of
the
Century Class Trucks Workshop Manual .
1. Park the vehicle on level ground, apply the park-
ing brakes, and chock the tires.
2. Clean the area around, and including, the fill
plug. Remove the plug from the oil fill hole (or
standpipe if installed in the oil fill hole) located in
the axle housing rear cover. See
Fig. 1 .
3. Place a drain pan under the rear axle drain plug.
Remove the drain plug at the bottom of the axle
housing and allow sufficient time for all old lubri-
cant to run out. See
Fig. 1 .
4. On dual-drive axles, also remove the plug at the
bottom of the power divider to drain oil from the
power divider.
NOTE: Some dual-drive axles are equipped with
a cylindrical magnetic strainer, below the lube
pump on the front of the power divider cover,
that must be removed and cleaned at each axle
oil change. All rear axles are fitted with mag-
netic drain and fill plugs. See
Fig. 2 .
5. Remove and clean the magnetic strainer, if so
equipped.
5.1 Remove the magnetic strainer from the
power divider cover.
WARNING
Always wear eye protection when using com-
pressed air to clean parts, as flying debris could
