Cayman 2006 Chassis Information — Section 10 • 247
Drive Shaft:
The drive shaft transfers the power produced by the engine to the drive axle. A worn or out of balance
driveline causes chassis vibration that generally increases in intensity with road speed.
NOTE:
It will be necessary to move the motorhome forward or backward to access all fittings on the
drive shaft.
Greasing the Drive Shaft Universal Joints:
1. Check the drive shaft for looseness.
Repair if loose or worn.
2. Apply the specifi ed grease at the
grease fi tting on the universal joint.
Apply until new grease purges from
all the seals.
3. If new grease does not purge at the
seals, loosen the bearing cap bolts
and re-grease until all four caps
purge. If new grease still does not
purge, disassemble and clean or
replace the universal joint.
Greasing the Drive Shaft Slip Yoke and Splines:
1. Check the drive shaft for looseness. Repair if loose or worn.
2. With fi nger, cover the rear air hole so grease fl ows to the front
seal. Apply the specifi ed grease at the grease fi tting on the slip
yoke. Apply until new grease purges and forces fi nger away
from the air hole in the end of the slip yoke. Greasing interval
is 5,000 miles or every six months.
WARNING:
Rotating shafts can be dangerous. Rotating shafts can snag clothes, skin,
hair, hands, etc. causing serious injury or death. Do not work on or near a
shaft “with or without a guard” when the engine is running.
U-Joint Angles, Phasing & Drive Shaft Balance
Correct U-joint working angles, U-joint phasing, and drive shaft
balance is vital to maintaining a quiet-running drivetrain and long
life of drivetrain components (including drive shaft components).
When in phase, the slip yoke lugs (ears) and tube yoke lugs
(ears) are in line. Normally this is the ideal condition and gives the
smoothest running shaft. There may be an alignment arrow stamped
on the slip yoke and on the tube shaft to assure proper phasing when
assembling these components. If there are no alignment marks, they
should be added before disassembly of the shaft to assure proper
reassembly.
