Repair
kits
for
the
universal
joints
are
not
available,
and
it
is
not
common
practice
to
repair
the
universal
joints
on
BMW
driveshafts
.
Worn
or
damaged
universal
joints
usually
require
replacement
of
that
section
of
the
driveshaft
.
The
driveshaft
is
balanced
to
cose
tolerances
.
Whenever
it
is
to
be
removed
or
disassembied,
the
mounting
flanges
and
driveshaft
sections
should
bemarked
with
paint
or
a
punch
before
proceeding
with
work
.
This
will
ensure
that
the
drive-
shaft
can
be
reassembled
or
installed

exactlythe

entation

The
alignment
of
the
driveshaft
does
not
normally
need
to
be
checked
unless
the
engine/transmission
orthe
final
drive
havebeen
removed
and
installed
.
If,
however,
all
other
parts
of
the
driveshaft
havebeen
inspected
and
found
to
be
okay,
butthere
is
still
noise
or
vibration,
driveshaft
alignment
should
be
checked
.
There
aretwo
important
driveshaft
alignment
checks
.
The
first
is
to
make
sure
that
the
driveshaft
runs
straight
from
the
transmission
to
the
final
drive
;
without
any
variation
from
side-
to-side
caused
by
misalignment
ofthe
engine/transmission
in
its
mounts
.
Make
a
basic
check
by
sighting
along
the
drive-
shaft
from
back
lo
front
.
Any
misalignmentshould
be
apparent
from
the
center
bearingforward
.
To
adjustthe
side-to-side
alignment,
loosen
the
transmission
or
engine
mounts
to
repo-
sition
them,
then
retighten
the
mounts
:
The
driveshaft
should
be
exactly
centered
in
the
driveshaft
tunnel
.

.
Driveshaft
should
be
cen-
tered
in
driveshaft
tunnel
.
The
second
important
driveshaft
alignment
check
is
more
complicated
.
It
checks
the
amount
the
driveshaft
is
angled
vertically
at
the
joints
.
This
angle
is
known
as
driveshaft
de-
flection
.
In
general,
there
should
be
little
deflection
in
the
driveshaft
between
the
engine,
thecenter
bearing,
and
the
final
drive
.
Precise
checks
require
theuse
of
a
large
protractor
or
some
other
means
of
measuring
the
angle
of
the
engine
and
the
fi-
nal
drive
and
comparing
these
angles
to
the
angle
of
the
drive-
shaft
sections
.
To
change
the
deflection
angle,
shims
can
be
placed
between
the
center
bearing
and
the
body
or
between
the
transmission
and
íts
rear
support
.
When
using
shims
to
change
a
deflection
angle,
keep
in
mind
that
the
angle
of
adjacent
joints
will
also
change
.
Deflection
anglesshould
beas
small
as
possible
.
