Differential Fluid Maintenance
DIFFERENTIAL FLUID
MAINTENANCECONDITION / CONCERN:
The service information and owners manual do not show a service interval for the 7.6, 8.6, 9.5, 9.75, 10.5, and 11.5 inch rear axles with or without G80 (locking differential).
RECOMMENDATION / INSTRUCTIONS:
These axles do not need to be serviced under normal operation due to the synthetic fluid that is used from the manufacturer.
