WARNING! Improper lubrication of U–joints can
cause them to fail prematurely. The driveshaft
could separate from the vehicle and result in an
accident causing death, injury or vehicle dam-
age. Make sure lubricant is purged at all four
ends of each U–joint and loosen caps if neces-
sary. Also, regularly inspect U–joints for exces-
sive wear or movement, and repair or replace as
necessary.
