©All limited slip and Traction-Lok axles use ESW-M2C-104-A lubricant (C6AZ-19580-C).

All conventional axles use ESW-M2C-105-A lubricant (C6AZ-19580-B).

©Approximate refill capacity-Actual lubricant capacities are determined
by
filling
to
bottom
of
filler hole.

©To check these axles, the plug should be backed
out
slowly.
If
seepage occurs around the threads, the plug should
be
turned back
in

immediately to avoid any drainage. This indicates that the specified amount
of
lubricant
is
present
in
the axle.
