Proper
handling,
stability,
tire

and
driving
ease
de-

pendupon
the
correct
alignment
of
al¡
four
wheels
.
The
front

axle
is
aligned
in
relation
to
the
rear
axie,
then
the
front
wheels

are
aligned
in
relation
to
one
another
.
This
is
known
as
a
four-

wheel
or
thrust-axis
alignment
.

The
BMW
E36
uses
a
sophisticated
multi-link
suspension

at
the
front
and
rear
of
the
car
.
Proper
alignment
requires

computerized
alignment
equipment
.

Front
and
rear
caster
and
Camber
are
both
fixed
by
the
de-

sign
of
the
car
.
Any
deviations
are
usually
the
result
of
worn
or

damaged
suspension
or
body
parts
.
