Driveshaft Lubrication
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 damage.

Also, regularly inspect U–joints for excessive
wear or movement, and repair or replace as
necessary.
