1. Park the vehicle on level ground, set the parking
brakes, and chock the tires.
IMPORTANT: Oil level must be checked at each
M1 interval on Meritor axles.
2. 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.
NOTE: Some Meritor 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.
3. Check that the lubricant is level with the bottom
of the fill hole. See
Fig. 2 . If low, check for oil
leaks, and correct as needed.
4. Install and tighten the fill plug 35 lbf·ft (47 N·m).
IMPORTANT: Always check the axle breather
whenever checking lubricant level. Check the
breather more frequently under adverse operat-
ing conditions.
5. Check the axle housing breather. Make sure that
it is open and unclogged. See
Fig. 7 . If the
breather is plugged or damaged, clean or re-
place it as needed.
6. On non-drive axles using oil-lubricated wheel
bearings, check the oil level at the wheels, and
add oil if low. Use the same lubricant recom-
mended for the drive axle.
NOTE: When adding to or checking the oil level,
make certain the hub cap and plug are clean
before removing the plug; this will minimize the
possibility of dirt and road grime entering the
assembly.

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 level ground, set the parking
brakes, and chock the tires.
2. If the vehicle has just been driven, allow a few
minutes for the lubricant to settle.
3. Clean the oil fill plug and the area surrounding it.
See
Fig. 8 . Remove the plug from the fill hole (or
standpipe, if installed in the oil fill hole).
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, or the top of
the standpipe opening.
