Lubrication
Lubrication for Universal Joints
Spicer recommends the following requirements be met for
any grease used to service most vehicular and industrial
applications and all auxiliary driveshaft applications:
• Use a good quality E.P. (extreme pressure) grease
(Timken Test Load - 50 lbs. / 23 kg. minimum), and
that
• Meets N.L.G.I. (National Lubricating Grease Insti-
tute) Grade 2 specifications, and has an
• Operating range of +325° F to -10° F (163° C to -
23° C), which is
• Compatible with commonly used multi-purpose
greases. For information about grease compatibility,
see the Grease Compatibility section below. Consult
your local grease source for greases that meet these
specifications.
Note: There are instances when special lubrication is required
due to original-equipment manufacturer specifications
or customer requests. The lubrication recommendations
listed in this manual are authorized by Spicer Driveshaft
engineering. Any alternate greases or lubrication proce-
dures are the responsibility of the user.
Grease Compatibility
To help reduce the effects of incompatible greases, be sure to
thoroughly purge all four bearing seals on each universal joint
with the new grease. Purge seals until the fresh grease is visi-
ble on the outside of all four bearing seals. It is recom-
mended that all purged grease be wiped clean to prevent
discharge into the general environment. Contact your local
grease supplier for grease compatibility information.
Lubrication Procedure for Universal Joints
Please refer to the Lubrication information in the Component
Safety section.
Required Materials:
• N.L.G.I. Grade-2, E.P. Grease
• Grease gun
May Need If Bearing(s) Will Not Purge:
• C-Clamp
• New straps
• New bolts
1. Use the proper grease to purge all four seals of each
universal joint. This flushes abrasive contaminants
from each bearing assembly and assures all four
bearings are filled. Purge the seals. Spicer seals are
made to be purged. Make sure fresh grease is evi-
dent at all four universal joint bearing seals.
2. If any of the seals fail to purge, try to push the drive-
shaft away from the seal that will not purge, while
applying grease gun pressure. There will occasion-
ally be one or more bearing assemblies that will not
purge.
