Spicer Life Series™ Driveshaft Installation 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 driveshaft
from falling, causing injury and/or damage during
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.
Reassembly of a driveline out of original phase can cause
vibration and failure of the driveline and attaching compo-
nents. Failure of a driveline can result in separation of
driveline from the vehicle, which can result in property
damage, serious personal injury or death.
Rotating bearing cup assemblies can result in yoke cross
hole wear and distortion. Distorted yokes can result in sep-
aration of the driveline from the vehicle.
Reuse of spring tab bolts or failure to properly tighten
spring tab bolts to required specifications can cause the
drivline to loosen and separate from the vehicle.
Failure to torque the midship nut to required specifications
can cause driveline failure, which can result in separation
of the driveline from the vehicle.
Reuse of boot clamps or failure to properly tighten boot
clamps to required specifications could allow intrusion of
contaminants onto slip member and can cause driveline
failure, which can result in separation of driveline from the
vehicle.
Attaching or entangling support straps to fuel, oil or brake
lines or wiring can result in their damage. Damaged fuel,
oil or brake lines or wiring can result in failure of the vehi-
cle.
Improperly seated bearing cup assemblies can cause drive-
line failure, which can result in separation of the driveline
from the vehicle.
Failure to install new stamped straps and new bolts and to
torque bolts to specification can cause driveline failure,
which can result in separation of the driveline from the
vehicle.
Installation of a driveline out of original phase can cause
vibration and failure of the driveline and attaching compo-
nents. Failure of a driveline can result in separation of the
driveline from the vehicle.
