DRIVESHAFT BALANCING

(SINGLE UNIVERSAL JOINT)

If rotating
the
driveshaft
180 de-

grees does
not
eliminate vibration,
the

driveshaft
may be
balanced using
the

following procedure:

1.
Place
the
vehicle
on a
twin post

hoist
so
that
the
rear
of the
vehicle
is

supported
on the
rear axle housing

with
the
wheels free
to
rotate.

2.
With
the
driveshaft rotating
at a

speedometer speed
of
40-50
mph,
carefully bring
a
crayon
or
colored

pencil
up
until
it
just barely contacts

the rearward
end of
driveshaft
(Fig.

6).
The
mark made
by the
crayon
or

pencil will indicate
the
heavy side
of

the shaft. Care should
be
exercised

when working near
the
balance

weights
to
prevent injury
to the
hands.

3.
Install
two
Whittek type hose

clamps
on the
driveshaft
so
that
the

heads
are
located
180
degrees from

the crayon marking
(Fig. 7).
Tighten

the clamps.
4.
Run the
vehicle
up to
65-70
mph

speedometer speed.
If no
vibration
is

felt, lower
the
vehicle
and
road test.
If

unbalance still exists rotate
the
clamp

heads approximately
45
degrees away

from each other
and
test
for
vibration

(Fig.
8).

5.
Continue
to
rotate
the
clamp

heads apart
in
smaller amounts until

vibration
is
eliminated.
To
prevent

overheating,
do not run the
vehicle

on
the
hoist
for an
extended period.
