SUSPENSION
AND
STEERING
TROUBLESHOOTING
Stable
handling
and
ride
comfort
both
depend
on
the
integ-
rity
of
the
suspension
and
steering
components
.
Any
symp-
tom
of
instability
or
imprecise
road
feel
may
be
caused
by
worn
or
damaged
suspension
components
.
When
troubleshooting
suspension
and
steering
problems,
also
consider
the
condition
of
tires,
wheels,
and
their
align-
ment
.
Tire
wear
and
incorrect
inflation
pressures
can
dramati-
cally
affect
handling
.
Subtie
irregularities
in
wheel
alignment
angles
also
affect
stabĂlity
.
Mixing
different
types
or
sizes
of
tires,
particularly
on
the
same
axle,
can
affect
alignment
and
may
unbalancea
car's
handling
.
Table
b
lists
the
symptoms
of
common
suspension
and
steering
problems
and
their
probable
causes,
and
suggests
corrective
actions
.
Bold
type
indicates
the
repair
groups
where
applicable
test

procedures
