Troubleshooting
NOTE-
With
the
driveshaft
installed,
theactual
amount
that
the
universal
joints
pivot
is
limited
.
For
the
most
accurate
test,
check
universal
joints
in
their
normal
range
of
movement
.
If
inspection
revealsnothing
wrong
with
the
driveshaft,
it
may
need
to
be
rebalanced
.
This
can
be
done
by
a
speciality
driveshaft
repair
shop
.
Also,
check
the
alignment
ofthe
drive-
shaft
as
described
below
.
