Spicer Life Series™ Driveshaft Removal 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 out of vehicle during the removal
and installation process.
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.
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, which can result in property damage, serious personal
injury or death.
DO NOT reuse bearing retainer bolts, stamped straps,
stamped strap bolts, damaged bearing retainers, or use
inferior grade bolts. Reuse of bearing retainer bolts,
stamped straps, stamped strap bolts, damaged bearing
retainers or the use of inferior grade bolts can cause drive-
line failure, which can result in separation of driveline from
the vehicle. A separated driveline can result in property
damage, serious personal injury or death.
DO NOT deform yoke cross holes by removing excessive
metal. Raised metal or deformed yoke cross holes can be a
cause of cross and bearing failure, which can result in sep-
aration of driveline from vehicle. A separated driveline can
result in property damage, serious personal injury or death.
DO NOT reuse flange bolts, washers or nuts or use inferior
grade bolts. Reuse of flange bolts, washers or nuts or use
of inferior grade bolts can cause driveline failure, which
can result in separation of driveline from the vehicle. A
separated driveline can result in property damage, serious
personal injury or death.
Driveshaft assemblies can weigh in excess of 100 pounds
(46 kilograms). Make sure to use proper lifting techniques
when handling driveshafts. More than one person may be
needed when handling driveshaft assemblies.
Hand tightening of grease zerk fittings or plugs is NOT rec-
ommended. Grease zerk fittings or plugs will eventually
vibrate loose and fall out of journal. Prolonged operation
with missing grease zerk fittings or plugs allows contami-
nants into the universal joint. Invasion of contaminatns into
the universal joint can degrade the lubricant and cause uni-
versal joint damage, which can result in separation of the
driveline from the vehicle. A separated driveline can result
in property damage, serious personal injury or death.
