Lubricate Wheel End
Before operating the axle, the wheel hub cavities and bear-
ings must be lubricated to prevent failure.
When wheel ends are serviced, follow Dana’s wheel end lubri-
cation procedure before operating the axle.
Dana axles may be equipped with either of two wheel end
designs:
• Wheel ends with an oil fill hole.
• Wheel ends without an oil fill hole.

through the wheel end fill hole.
10. Install oil fill plug and tighten to specified torque.
