outside temperatures above 70°F (21°C) and
at wide-open throttle for long periods above
45 mph (72 km/h), change non-synthetic rear
axle fluid every 3,000 mi (4,800 km) or three
months, whichever comes first. This interval
can be waived if the axle is filled with

Axle Maintenance
Change the axle fluid anytime an axle is
submerged in water.
