1. If NoSPIN® installed differential, check the petroleun based oil or syntetic oil, in the minimum interval of the 40.000
miles (64.000 km) or maximum interval of the 50.000 miles (80.000 km).
2. For continuous cycle operations, check the oil level every 1.000 miles (1.600 km). Add the type and amount of suit-
able oil to it.
3. This interval applies to approved semi-synthetic and synthetic oils only. For a list of approved extended-drain axle
oils, see the TP-9539, Approved Rear Drive Axle Lubricants. To obtain this publication, see the Service Notes page
on the front inside cover of this manual.
