Spicer Single Speed Axle - Service Manual - Manual (Page 26)

SECTION 4
SPECIFICATIONS
DIFFERENTIAL LUBRICATION
It is not our intent to recommend any particular brand or make of lubricant for the Spicer hypoid axle. However, an S.A.E.
8OW-90 multi-purpose gear lubricant meeting Mil. Spec. L-2105C, and suitable for 1 A.P.I. Service Classification GL5, is
suggested as a minimum requirement.
IMPORTANT
Motor vehicles are operated under various requirements, conditions, and environments. This manual specifies
the minimum requirements that the lubricants should meet. However, it is recommended that the lubricants
specified by the vehicle manufacturer be used. They may provide additional lubricating characteristics which may
be required for your vehicle’s operation. Contact your local service dealer or refer to your owner’s manual for
obtaining the proper lubricant specification.
AXLE LUBRICANT CHANGE SCHEDULE
The following schedule is a suggested lubricant change schedule. Lubricant in your vehicle may require more frequent
changes depending upon the environment in which it is operated in. Contact your local service dealer or refer to your
owner’s manual for obtaining the proper lubricant change schedule for your vehicle.
Drain lubricant at first oil change and refill with specified lubricant. FOR NORMAL ON HIGHWAY USE, change
lubricant every 100,000 miles or 24 months, whichever comes first. FOR OFF HIGHWAY, SANDY, DUSTY, OR WET
CONDITIONS, change lubricant every 25,000 miles or 6 months, whichever comes first.
Lubricant may be drained by removing the carrier cover plate. This also allows for visual inspection of the internal
components. Follow the service procedure in the manual for reassembly of the cover plate.
WHEEL BEARING LUBRICATION
Wheel bearings are lubricated by packing with grease. For grease packing it is recommended that a 2 N.L.G.I. No. 2
lithium EP grease suitable for automotive wheel bearings be used. Contact your local vehicle service dealer or refer to
your owner’s manual for obtaining the proper lubricant specification, and maintenance schedule.
SUBMERSION OR DEEP WATER FORDING
If the vehicle is exposed to water deep enough to cover the hubs, it is recommended that the wheel ends be diassembled
and inspected for water damage and/or contamination.
In the event the carrier housing should become submerged in water, particularly if over the breather, it is recommended
that the hypoid gear lubricant be drained and internal parts be inspected for water damage and/or contamination.
Clean, examine, and replace damaged parts if necessary, prior to assembling the housing cover and refilling with the
specified hypoid lubricant.
NOTE
If the hubs are exposed to deep water, it is possible that the water could enter the carrier at the point the axle
shaft enters the tube in the wheel end. This could also necessitate the draining of the hypoid lubricant as described
above.
It is recommended that whenever bearings are removed, they be replaced with new ones, regardless of
mileage.
