U-joints and driveshafts
should be inspected every time
a vehicle comes in for scheduled

U-Joints
The slip joints and universal joints of
the drive shaft should be lubricated
according to
Preventive Maintenance
Schedule on
page 5-12.
Use a
good quality lithium-soap-base
or equivalent extreme pressure (E.P.)
grease: NLGI Grade 2.
Use only
Spicer Driveshaft approved
lubricants when greasing Spicer SPL
U-joints.
For SPL170XL
and SPL250XL, the
U-joint lube interval changes after the
initial lube at 350,000 miles. After
the rst lube interval, the U-joint
needs lubrication every 150,000 miles.
Inspection of the U-joints is the same
regardless of when the U-joint grease
interval occurs.
WARNING!
Improper lubrication of U-joints can
cause them to fail prematurely. The
driveshaft could separate from the ve
-
hicle and result in an accident. Make
sure lubricant is purged at all four ends
of each U-joint and loosen caps if nec
-
essary. Also, regularly inspect U-joints
for excessive wear or movement, and
repair or replace as necessary. Fail
-
ure to comply may result in death,
personal injury, equipment or property
damage.
