DRIVESHAFT
Greasable slip joints and universal joints of the drive shaft should be
lubricated periodically.
Use a good quality lithium-soap base or equivalent extreme pressure (E.P.)
grease: NLGI Grade 2.
For towing guidelines and returning a towed vehicle to service see page
163.
U-JOINTS
The slip joints and universal joints of the drive shaft should be lubricated
according to Recommended Maintenance Schedules, pages 315-342.
Use a good quality lithium-soap base or equivalent extreme pressure (E.P.)
grease: NLGI Grade 2.
Improper lubrication of U-joints can cause them to fail prematurely.
The driveshaft could separate from the vehicle and result in an injury
accident and/or vehicle damage. Make sure lubricant is purged at
all four ends of each U-joint and loosen caps if necessary. Also,
regularly inspect U-joints for excessive wear or movement and repair
or replace as necessary.
