All Spicer Carrier Type
axles are identified with
a manufacturing date (1) and Bill of Material number (2) stamped on the
right or left hand tube on driving axles. The Bill of
Material number may also be found on the carrier in some models as
shown in illustration (2A). For independent
front suspension (IFS) axles, the B/M number may be located at one of
three locations: 1). A vertically
positioned tag near the center of the right hand side support arm, 2)
stamped into the left hand side support arm
(opposite end of the camber adjuster), or 3) stamped into the "nose
end" of the axle carrier. The location of
the information will depend on the manufacturing date of the axle.
The axle model number
will be cast into one of the webs as shown (3),
or it can be on the nose.
Each axle contains a gear
ratio tag (4), and if the axle is equipped
with a limited slip differential, it will have a tag specifying the
type of limited slip lubricant to be used (5).
