Wheel End
Wheel End Lubrication Procedure
Before operating the axle, the wheel hub cavities and
bearings must be lubricated to prevent failure.
When wheel ends are serviced, follow Dana’s wheel end
lubrication procedure before operating the axle.
Spicer 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
Wheel End Lubrication Procedure
(with oil fill hole)
1. Rotate the wheel end hub until the oil fill hole is up.
2. Remove the oil fill plug.
3. Pour 0.5 pint [0.2 liter] of axle sump lubricant into
each hub through the wheel end fill hole.
4. Install oil fill plug and tighten to specified torque.
Wheel End Lubrication Procedure (without oil fill
hole)
1. With axle level and wheel ends assembled, add
lubricant through filler hole in axle housing cover
until fluid is level with the bottom of filler hole.
2. Raise the left side of the axle 6 in. [152 mm] or
more. Hold axle in this position for one minute.
3. Raise the right side of the axle 6 in. [152 mm] or
more. Hold axle in this position for one minute.
4. With axle on a level surface, add lubricant through
housing cover oil filler hole until fluid is level with
the bottom of the hole.
Note: Axles without wheel end fill holes require approxi-
mately 2.5 pints [1.2 liters] of additional lubricant to
bring the lubricant level even with the bottom of the fill
hole.
