- Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
- Clean the fill plug and the area around it. In the axle
housing rear cover, remove the plug from the oil fill hole (or standpipe,
if installed in the oil fill hole). See Fig..

- Place a drain pan under the rear axle drain plug. See Fig.. Drain the oil at normal operating temperature, 150 to 200°F (65 to 93°C). At this temperature, the oil will run more freely and ensure that the axle is flushed.
- At each axle oil change, remove and clean the magnetic
strainer, if equipped. See Fig..

- Remove the magnetic strainer from the power divider cover.
Warning: Always wear eye protection when using compressed air to clean parts, as flying debris could cause permanent damage to unprotected eyes. Do not point the air stream in the direction of other persons.
- Wash the strainer in solvent, and blow it dry with compressed air to remove oil and metal particles.
- Install and tighten the magnetic strainer 40 to 60 lbf·ft (54 to 81 N·m).
-
- Clean the fill and drain plugs. Change them if necessary.
- For magnetic plugs, use a piece of key stock or any other convenient steel slug to short the two magnetic poles and divert the magnetic field.
- Clean away the collected material deposited on each pole. Magnets will rapidly lose their effectiveness as collected material bridges the gap between the two poles.
- After the first oil is changed, inspect the drain plug each time for large quantities of metal particles.
- After cleaning, install the drain plug(s) and tighten to 40 to 60 lbf·ft (54 to 81 N·m).
- Fill the axle with the recommended lubricant. See Table. for recommended
drive axle lubricants, and Table. for drive
axle lubricant capacities.

- Quantities listed are approximate. Fill axle until lubricant is level with bottom of fill hole with vehicle on level ground.
- Add 2 pints (1 L) of additional lubricant to the power divider.
Table 3, Dana Spicer Drive Axle Lubricant Capacities
- Fill the axle through the oil fill hole or standpipe opening.
Lubricant should be level with the bottom of the oil fill hole, or
the top of the standpipe opening. To check fluid level, see Fig..
-
Correct (lube level at bottom of fill hole)

- Install and tighten the fill plug 40 to 60 lbf·ft (54 to 81 N·m).
Important: The use of friction modifiers is not approved in Dana drive axles.
Note: Some tandem drive axles are equipped with a cylindrical magnetic strainer, located below the lube pump on the front of the power divider cover. All rear axles are fitted with magnetic drain and fill plugs.
Note: Some Dana Spicer axles have a small tapped and plugged hole near and below the housing oil fill hole. This smaller hole is for a lubricant temperature indicator only, and should not be used as a fill or level hole.
