Component Safety
Driveline
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.
Reassembly of a driveline out of original phase can cause
vibration and failure of the driveline and attaching compo-
nents. Driveline failure can result in separation of the driveline
from the vehicle, resulting in property damage, serious per-
sonal injury, or death.
Driveshaft assemblies can weigh in excess of 100 pounds (46
kilograms). Be sure to use proper lifting techniques when
handling driveshafts. More than one person may be needed
when handling driveshaft assemblies.
Never heat components, never use sledge hammers, and
never use floor jacks to disassemble driveshafts. This can
result in damaged, weakened, or bent components.
End Fitting
A loose end-fitting can result in driveline failure, which can in
turn lead to separation of the driveline from the vehicle. A sep-
arated driveline can lead to property damage, serious per-
sonal injury, or death.
Universal Joint
Excessive looseness across the end of universal joint bearing
cup assemblies can cause imbalance or vibration in the drive-
shaft assembly. Imbalance or vibration can cause component
wear, which can result in separation of the driveline. A sepa-
rated driveline can lead to property damage, serious personal
injury, or death.
DO NOT reuse bolts or use inferior grade bolts. Reuse of bolts
and/or use of inferior grade bolts can cause driveline failure,
which can result in separation of the driveline from the vehi-
cle. A separated driveline can result in property damage, seri-
ous personal injury, or death.
Failure to torque bolts to specification can cause driveline fail-
ure, which can result in separation of the driveline from the
vehicle. A separated driveline can result in property damage,
serious personal injury, or death.
Use a journal locator to avoid nicking journal cross trunnions
or damaging oil seal slingers.
If a bearing assembly or journal cross is worn or damaged,
the universal joint assembly must be replaced.
Be sure the snap rings are properly seated in the snap ring
grooves.
Slip Member
Excessive radial looseness in the slip member assembly can
cause imbalance or vibration in the driveshaft. Imbalance or
vibration can cause components to wear, which in turn can
result in separation of the driveline from the vehicle. A sepa-
rated driveline can cause property damage, serious personal
injury or death.
Yoke (Includes Slip Yoke, Yoke Shaft, and Tube
Yoke)
A loose or damaged slip yoke seal allows contaminants to
invade the slip member assembly. Invasion of contaminants
into the slip member assembly can degrade the grease, and
damage slip member components, which can result in drive-
line separation. 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 separa-
tion of the driveline from the vehicle. A separated driveline can
result in property damage, serious personal injury, or death.
Yoke shaft assemblies can weigh in excess of 50 pounds
(23 kilograms). Be sure to use proper lifting techniques when
handling yoke shafts.
