Safety
Lubrication (When Applicable)
A missing, loose, or fractured grease zerk (nipple) fitting or
plug eliminates the ability to lubricate the universal joint.
Improper or inadequate lubrication 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.
Improper lubrication techniques 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.
A missing, loose, damaged, or fractured plug or grease zerk
(nipple) fitting can allow contaminants to invade the universal
joint. Invasion of contaminants into the universal joint can
degrade grease and cause universal joint damage, which can
result in separation of the driveline from the vehicle. A sepa-
rated driveline can result in property damage, serious per-
sonal injury, or death.
Incompatible greases that are applied to universal joints and/
or slip members can result in driveline failure and can result in
separation of the driveline from the vehicle. A separated drive-
line can result in property damage, serious personal injury, or
death.
Hand tightening of grease zerk (nipple) fittings or plugs is
NOT recommended. Failure to torque grease zerk (nipple) fit-
tings to specifications can result in separation of the driveline
from the vehicle. A separated driveline can cause property
damage, serious personal injury, or death.
In cold temperatures, be sure to drive the vehicle immediately
after lubrication. This activates the slip spline and removes
excess grease. Failure to do so could cause excess grease to
stiffen in the cold weather and force the plug out. The end of
the spline would then be open to collect contaminants and
cause the spline to wear and/or seize.
All slip yoke and universal joint seals should be completely
purged.
