DRIVE SHAFTS
SUP-YOKE LUBRICATION
When equipped with lube fittings, it is recom­
mended that the slip-yoke splines be lubricated at
the intervals described in the Maintenance Schedules
section of this Group. Refer to Group 16, Propeller
Shafts for proper service procedures.
LUBRICANT SPECIFICATION
Use Mopar, Multi-purpose Grease or any lubricate
that is identified as NLGI GC-LB lubricant.
RUBBER AND PLASTIC HOSES/TUBING
The condition of underbody rubber hose and plastic
tubing should be inspected whenever underbody ser­
vice is performed.
Rubber hoses and plastic tubing should be re­
placed immediately if there is any evidence of
failure.
HOSE/TUBING INSPECTION
Vehicle operating conditions determine the useable
life of underbody hoses and tubing. These conditions
include:
• The extent and quality of vehicle maintenance.
• The geographic area of vehicle operation.
• The length of exposure time to excess heat and
chemical contaminants.
(1) Inspect all hose and tubing fittings for loose­
ness and corrosion. Inspect the rubber hoses for brit-
tleness and cracks. Thoroughly inspect the hose ends
(those that are slipped over nipple connectors) for
splits.
(2) Inspect the surface of hoses and tubing for heat
and mechanical damage. Hose and tubing located
close to an exhaust pipe should be given special at­
tention.
(3) Inspect the rubber hose routing to ensure that
the hoses do not contact any heat source, moving
component, etc., that would potentially cause heat or
mechanical damage.
(4) Inspect all the hose connections to ensure that
they are secure and there is no fluid leakage. Actual
dripping of hot fluid should be noted and the clamps
tightened in an attempt to stop the leakage before re­
placing the hose.
