Lubrication
Change Lube
Drain
1. Drain when the lube is at normal operating tempera-
ture. It will run freely and minimize the time neces-
sary to fully drain the axle, this insures the axle is
flushed. Drain into suitable container with lube at
normal operating temperature. Inspect drain plug for
excessive metal particle accumulation symptomatic
of extreme wear. Clean and replace plug after drain-
ing
2. Unscrew the magnetic drain plug on the underside of
the axle housing and allow the lube to drain into a
suitable container.
Note: Dispose of all used lubricants properly by following dis-
posal methods approved for mineral or synthetic based
oils.
3. After initial oil change, inspect drain plug for large
quantities of metal particles. These are signs of dam-
age or extreme wear in the axle. Clean the drain plug
and replace it after the lube has drained completely.
Inspect breather for clogging or corrosion. Clean or
replace as necessary.
Note: After initial lube change, the entire unit should be
inspected if excessive particle accumulation is observed.
Fill
1. With vehicle on level ground, remove the filler hole
plug from the axle housing cover and fill the axle
with approved lubricant until level with the bottom of
the hole.
2. If wheel ends were removed, follow instructions in
wheel end servicing section.
Always use the filler hole as the final reference. If lube is level
with the bottom of the hole, the axle is properly filled.
Note: Lube fill capacities (see chart) are basic guidelines and
will vary based on the angle the axle is installed in a par-
ticular chassis. Torque fill plug to 40–60 lbs. ft. (54–82
N•m).
TIP: The axle can be filled through the axle housing breather
hole. Fill until lube level is even with the bottom of filler hole in
axle housing rear cover.
Axles installed at angles exceeding 6° or operated regularly on
grades exceeding 12% may require stand-pipes to allow
proper fill levels. For specific information, contact Axle &
Brake Engineering Department.
