Rear Axle Lubrication

The ability of any axle to deliver quiet, trouble-free operation over a period of years is largely dependent upon the use of good quality gear lubricants. To insure long life for gears and bearings, use only specified hypoid gear lubricants. Dana and Ford axles use different lubricants as follows:

^ Ford requires ESP-M2C154-A (EOAZ-1 9580-AA)

^ Dana requires ESW-M2C105-A (C6AZ-19580-E)

Draining Dana Axles

Dana axles do not have a drain plug. The cover should be loosened and removed from the housing to allow drainage. The RTV Sealer must be removed from the cover and axle housing. Reseal with Silicone Rubber, E7TZ-1 9562-A ESL-M4G273-A or equivalent.

Filling Ford Axle

The filler hole is in the carrier casting. Fill to the bottom of the hole with the exception of Bronco.

To check these axles for proper lubricant level, the filler plug should be backed out slowly. If seepage occurs around the threads of the plug, immediately turn the plug back in to avoid any drainage. This condition indicates that the specified amount of lubricant is in the axle.

NOTE: The Bronco lube level may be 6.3 mm (1/4 inch) below the filler hole. It is not necessary to fill above this level.

Dana Front and Rear Axles

Fill the axle through the cover filler hole until oil flows from the bottom of the hole. After filling the axle with the specified amount of lubricant, install the oil filler hole plug.
