2.Raise one wheel on each axle for rotation of
propeller shaft as necessary to access fixings.
CAUTION: When working on the propeller
shafts:
lAlways remove the propeller shafts and
viscous coupling as an assembly.
Dismantling the individual units on the
vehicle may cause damage to the
components.
lNever unbolt the viscous coupling
support bearings from the body without
first detaching the propeller shafts at the
differential and IRD. The weight of the
centre section will pull the CV joint apart,
causing irreparable damage.
lNever allow the CV joint to be
manipulated to an acute angle. This will
cause the internal roller bearings to
break up, leading to excessive backlash
and CV joint failure.
