35–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
When working on the vehicle, shut down the
engine or motor, set the parking brake, and chock
the tires. Before working under the vehicle, always
place jack stands under the frame rails to ensure
the vehicle cannot drop. Failure to follow these
steps could result in serious personal injury or
death.
35–01 Axle Lubricant and Filter
Change, and Magnetic
Strainer Cleaning
NOTICE
When operating under adverse conditions, it may
be necessary to change the axle lubricant at more
frequent intervals than listed in the scheduled
maintenance tables. Failure to do so could result
in axle damage.
For all axles, including tandem drive axles and two-
speed axles, perform the applicable procedures
under ’All Axle Models.’
All Axle Models
Detroit® eAxle
1. Park the vehicle on a level surface, shut down
the vehicle, and set the parking brake. Chock the
tires.
2. Clean the fill plug and the area around it. In the
axle housing rear cover, 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
contacts the skin.
3. Place a drain pan under the rear axle drain plug.
Drain the oil when it is warm. At this
temperature, the oil will run more freely and
ensure that the axle is flushed.
4. Clean the fill and drain plugs. 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
deposited on each pole. Magnets will
rapidly lose their effectiveness as
collected material bridges the gap
between the two poles.
4.3 After the first oil is changed, inspect the
drain plug each time for large quantities
of metal particles.
4.4 After cleaning, install the drain plug(s)
and tighten 30 lbf·ft (41 N·m).
5. Fill the axle with the recommended lubricant.
See
Table 1 for lubricant capacities.
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.
5.1 Fill the axle through the oil fill hole.
Lubricant should be level with the bottom
of the oil fill hole. To check fluid level, see
Fig. 2 .
IMPORTANT: Lubricant used in Detroit rear
axles must meet Mercedes-Benz
specification MB 235.31/Detroit Fluids
Specification (DFS) 93K219.03. For more
product information, see DDC-SVC-BRO-
0119 on the DTNA Connect Portal.
5.2 Install and tighten the fill plug 30 lbf·ft (41
N·m).
