Inspection
Spicer 10 Series™ Driveshafts should be carefully inspected
at recommended original-equipment manufacturer’s service
intervals and/or at Spicer recommended lubrication intervals
as shown in the Lubrication section on page 11.
End Fitting Inspection
This information refers to axle, transmission, transfer case,
and center bearing end fittings. Please refer to the End Fitting
information in Component Safety on page 2.
1. Visually inspect all end-fitting retaining nuts or bolts
for any gaps or looseness between mating surfaces.
If gaps are present, consult transmission, axle, or
transfer case original-equipment manufacturer’s ser-
vice and maintenance manual for proper fastener
specifications. If looseness is evident between the
nut, yoke, or center bearing, take the driveshaft to a
qualified driveshaft facility for further inspection and
repair.
2. Check all end fittings for looseness. Grasp the end
fitting with both hands and try to move it vertically
and horizontally to feel any looseness.
3. Grasp the end fitting with both hands and rotate left
to right, feeling for play and backlash. There should
not be any movement in the end fittings relative to
the output or input shafts to which they are con-
nected. If looseness is evident, consult transmission,
axle, or transfer case original-equipment manufac-
turer’s service and maintenance manuals for proper
end fitting to shaft specifications.
4. Visually inspect for:
• damaged half round bearing straps
• loose bearing strap bolts
• loose companion flange bolts and nuts
• damaged or worn tangs on end fittings
• damaged or missing snap rings
• rotating bearing cups
If any of these conditions are present, component replace-
ment is necessary. Refer to the original-equipment manufac-
turer’s recommendations for removal instructions.
