For n o r m a l service, periodic f l u i d level checks are
not required. W h e n the vehicle is serviced for other
reasons, however, the exterior surfaces o f the axle as-
sembly should be inspected for evidence o f gear o i l
leakage. Perform a f l u i d level check t o confirm sus-

Confirmed leakage should be repaired as soon as pos-
sible.
