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 en-
gine 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 Level
Check
NOTICE
Failure to keep the rear axle filled to the proper
level with the recommended lubricant can result in
rear axle damage.
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.
2. If the vehicle has just been driven, allow a few
minutes for the lubricant to settle.
NOTE: Some Detroit and Meritor axles have a
small tapped and plugged hole located below
the housing oil fill hole. This smaller hole is for
the lubricant temperature sensor only and must
not be used as a fill or level hole.
3. Clean the oil fill hole plug (located in the carrier
or the side of the axle housing) and the area sur-
rounding it, then remove the plug.
For Detroit axles, see Fig. 1 ; for Meritor axles,
see Fig. 2 ; for Dana Spicer axles, see Fig. 3 .
IMPORTANT: A lubricant level close enough to
be seen or touched is not sufficient. It must be
level with the bottom of the fill hole.
4. Check the level of the lubricant. The lubricant
must be level with the bottom of the oil fill hole.
See
Fig. 4 . If low, add lubricant.
For Detroit axles, see Table 1 for approved axle
lubricants and Table 2 for lubricant capacities.
For Meritor axles, see Table 3 for approved axle
lubricants, and Table 4 or Table 5 for axle ca-
pacities.
