Changing Differential Lubrication
Draining
Drain when the lube is at normal operating
temperature. It will run freely and minimize the
time necessary to fully drain the axle.
1. Make sure the drain plug is at the bottom
most position on the axle being serviced.
2. Unscrew the magnetic drain plug and allow
the lube to drain into a suitable container.
3. Clean the drain plug.
4. Install drain plug and O-Ring (WR10 and
12) or sealant (WR3, 5 and 7).
IMPORTANT: Used lubricants are dangerous
environmental pollutants. Dispose of all
lubricants properly.
Filling
1. Remove the filler hole plug from the front of
the planetary gear housing. Make sure that
the filler hole is in a horizontal line with the
center of the wheel hub.
2. Fill the wheel hub with approved lubricant
until level with the bottom of the filler hole.
3. Install fill plug and O-Ring (WR10 and 12)
or sealant (WR3, 5 and 7).
