vice Procedure
Wheel End Lubrication
Before operating the axle, the wheel hub cavities and bearings must be lubricated to prevent failure. When wheel ends are
serviced, follow
Spicer’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 Ends with an oil fill hole proceed as follows: (Fig. 1)
1. Rotate the wheel end hub until the oil fill hole is up.
2. Remove the oil fill plug.
3. Pour 1/2 pint of axle sump lubricant into each hub through the wheel end fill hole.
4. Install oil fill plug and tighten to specified torque.
