maintenance tables. Failure to do so could result
in axle damage.
Detroit Axles
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.
2. Clean the oil fill plug and the area around it, then
remove the plug from the oil fill hole. See
Fig. 1.
CAUTION
Be careful when draining the axle oil. It may be
very hot, and could cause personal injury if it con-
tacts the skin.
3. Place a drain pan under the rear axle drain plug.
Drain the oil when it is warm. At this tempera-
ture, the oil will run more freely and ensure that
the axle is flushed.
4. Clean the fill and drain plugs as follows. Change
them if necessary.
4.1 For magnetic plugs, use a piece of key
stock or any other convenient steel slug
to short the two magnetic poles and divert
the magnetic field.
4.2 Clean away the collected material depos-
ited on each pole. Magnets will rapidly
lose their effectiveness as collected mate-
rial bridges the gap between the two
poles.
4.3 Inspect the drain plug for large quantities
of metal particles.
4.4 After cleaning, install the drain plug(s)
and tighten to 30 lbf·ft (41 N·m).
NOTE: Some Detroit axles have a small tapped
and plugged hole near and below the housing
oil fill hole. This smaller hole is for a lubricant
temperature indicator only, and should not be
used as a fill or level hole.
5. Fill the axle with the recommended lubricant as
follows. See
Table 1 for approved axle lubricants
and Table 2 for lubricant capacities.
5.1 With the vehicle on a level surface, fill the
axle through the oil fill hole. Lubricant
should be level with the bottom of the oil
fill hole.
5.2 Check the fluid level; see
Fig. 4.
5.3 Install and tighten the fill plug 30 lbf·ft (41
N·m).
Meritor Axles
IMPORTANT: If using synthetic lubricant, the
lubricant change interval is extended to 100,000
miles (160 000 km). On axles with a pump and
filter system, the filter change interval is 100,000
miles (160 000 km).
1. Park the vehicle on level ground, apply the park-
ing brakes, and chock the front tires.
NOTE: Some Meritor axles have a small tapped
and plugged hole near and below the housing
lubricant fill hole. This smaller hole is for a lubri-
cant temperature indicator only, and should not
be used as a fill or level hole.
2. Clean the area around the fill plug, then remove
the fill plug.
3. Place a drain pan under the drain plug, then re-
move the drain plug from the bottom of the hous-
ing. Completely drain the lubricant while the unit
is warm, to allow the lubricant to drain faster.
On tandem-drive axles, it is also necessary to
remove the plug at the bottom of the interaxle
differential housing to drain that lubricant.
4. If equipped with an oil pump, replace the filter.
NOTE: There may be about one pint (0.5 L)
of lubricant remaining in the filter.
4.1 Remove the axle oil filter using a suitable
filter strap wrench (see Fig. 5) and dis-
card it.
4.2 Using recommended drive axle lubricant
(see
Table 3), coat the face of the gasket
on the new oil filter.
4.3 Install the filter over the adapter, and
tighten the filter one full turn after the
gasket contacts the base; do not
overtighten.
5. Clean the fill and drain plugs as follows. Change
them if necessary.
5.1 For magnetic plugs, use a piece of key
stock or any other convenient steel slug
