Drive Axle Lubrication Procedure

Drain Axle Sump
1. Before draining, lubricant temperature must be
between 60° and 120° F [15.5° and 48.8° C].
2. Put drain pan under drain plug located on the
underside of the axle housing.
3. Unscrew magnetic drain plug and drain the lubri-
cant.
4. Inspect plug for large quantities of metal particles.
If present, inspect entire unit.
Fill Axle Sump (and Wheel Ends, if necessary)
Note: If wheel ends were removed, they must be filled with
the same lubricant as the axle sump.
1. Wipe clean all internal cavities or the hubs.
2. Lubricate the wheel bearings using the same lubri-
cant as in the housing.
Note: Do not use wheel bearing grease.
3. Fill inner hub cavities before installing onto axle
housing spindles.
4. If the hub has a fill hole, add 1.5 pints [0.7 liters].
5. If hub does not have a fill hole, raise the opposite
axle end 8 in. [203 mm] for at least 1 minute.
6. If the wheel ends were filled by jacking up the axle
ends, recheck the main sump and top off if neces-
sary until oil reaches the bottom of the fill hole.
