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
Checking
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.
3. Clean the fill plug and the area surrounding the
fill plug on the side of the axle carrier. Remove
the plug. Check lubricant level when the axle is
cold, or near room temperature. See
Fig. 1 and
Fig. 2 .
NOTE: Some 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.
4. Check that the lubricant is level with the bottom
of the fill hole. See
Fig. 3 . If low, check for oil
leaks, and correct as needed. Add oil to the level
of the fill plug, using the lubricant in
Table 1 for
Detroit axles or Table 2 for Meritor axles.
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.
5. Install the oil fill plug and tighten it 30 lbf·ft (41
N·m) for Detroit axles or 35 lbf·ft (47 N·m) for
Meritor axles.
IMPORTANT: Always check the axle breather
whenever checking the lubricant level. Check
the breather more frequently under adverse op-
erating conditions.
6. Check the axle housing breather. Make sure that
it is open and unclogged. If the breather is
plugged or damaged, clean or replace it as
needed.
