Driveshaft Maintenance

The slip joints and universal joints of
the driveshaft should be lubricated
periodically.
Use a good quality lithium-soap-base
or equivalent extreme pressure (E.P.)
grease: NLGI Grade 2.
Dana SPL U-joints and driveshafts
should be inspected every time
a vehicle comes in for scheduled
maintenance (Refer to Spicer
Driveshaft service manual DSSM-0100
5
(3264-SPL) for detailed instructions).
Use only Spicer Driveshaft approved
lubricants when greasing Spicer SPL

U-joints.

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.
Y53-6060-1C1
For SPL170XL and SPL250XL, the
U-joint lube interval changes after the
initial lube at 350,000 miles. After
the first 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 happens.
WARNING!
Improper lubrication of U-joints can
cause them to fail prematurely. The
driveshaft could separate from the
vehicle and result in an accident.
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. Failure to comply
may result in death, personal injury,
equipment or property damage.
