WARNING
A gearbox oil leak at the driveshaft may destroy it.
WARNING
Lubricate the base of the bearing with MOLYKOTE
to prevent the bear ing sticking.
Make sure that the O-ring is correctly positioned in
the base of the relay bearing, if the bearing has
one.

Always replace seals whenever the driveshaft is
removed.
WARNING
Always replace the left-hand driveshaft lock ring, if
the driveshaft has one.
WARNING
In order to prevent irreversible damage to the front
hub bear ing:
-Do not loosen or tighten the driveshaft nut when
the wheels are on the ground.
-Do not place the vehicle with its wheels on the
ground when the driveshaft has been loosened or
