Spicer Life Series™ Inspection Warnings and Cautions
Before You Get Started
1. ALWAYS wear safety glasses when performing
maintenance or service. Failure to wear safety
glasses can result in personal injury and/or partial or
complete vision loss.
2. NEVER go under a vehicle while the engine is run-
ning. Be sure the vehicle's engine is off, and keys are
removed from ignition.
3. NEVER go under or work on a vehicle that is not on a
level or flat surface.
4. NEVER work on a driveshaft without blocking the
vehicle's wheels and releasing all parking brakes.
See warning below.
5. NEVER lift a vehicle without the appropriate weight-
rated, vehicle-support equipment.
6. NEVER REMOVE a driveshaft from the vehicle with-
out keeping the vehicle's transmission in neutral.
See above warning.
7. CAUTION – Spicer Life Series™ driveshaft assem-
blies can weigh in excess of 100 pounds (46 kilo-
grams). Be sure to use proper lifting techniques
when handling Spicer Life Series™ driveshafts. More
than one person may be needed when handling
driveshaft assemblies.
8. ALWAYS use support straps to prevent the drive-
shaft from falling, causing injury and/or damage dur-
ing the loosening or removal of any driveshaft
hardware.
9. NEVER heat components or use sledgehammers or
floor jacks to remove the driveshaft from vehicle.
Note: For driveshaft applications that have pillow blocks,
dampers, parking brakes or retarders, refer to these
component manufacturers' or the original equipment
vehicle manufacturers' service manuals for proper pro-
cedures.
Driveline
WARNING: Failure to replace damaged driveline components
can cause driveline failure, which can result in separation of
the driveline from the vehicle. A separated driveline can result
in property damage, serious personal injury, or death.
WARNING: Reassembly of a driveline out of original phase
can cause vibration and failure of the drivline and attaching
components.
WARNING: Driveshaft assemblies can weigh in excess of 100
pounds(46 kilograms). Be sure to use proper lifting tech-
niques when handling driveshafts. More than one person
may be needed when handling driveshaft assemblies.
WARNING: Never heat components, never use sledge ham-
mers, and never use floor jacks to disassemble driveshafts.
This can result in damaged, weekened, or bent components.
End Fitting
WARNING: A loose end-fitting can result in driveline failure,
which can in turn lead to separation of the driveline from the
vehicle. A separated driveline can lead to property damage,
serious personal injury, or death.
Universal Joint
WARNING: Excessive looseness across the end of universal
joint bearing cup assemblies can cause imbalance or vibration
in the driveshaft assembly. Imbalance or vibration can cause
component wear, which can result in separation of the driv-
line.
WARNING: DO NOT reuse bolts or use inferior grade bolts.
Reuse of bolts and/or use of inferior bolts can cause driveline
failure, which can result in separation of the drivline from the
vehicle.
WARNING: Failure to torque bolts to specification can cause
driveline failure, which can result in separation of the driveline
from the vehicle.
CAUTION: Use a journal locator to avoid nicking journal cross
trunnions or damaging oil seal slingers.
CAUTION: If a bearing assembly or journal cross is worn or
damaged, the universal joint assembly must be replaced.
CAUTION: Be sure the snap rings are properly seated in the
snap ring grooves.
