There

no

frequent

is

required
However

when

the

INSPECTION

Wheel
balance

The
wheel
and
tire

assembly
should
be

kept
balanced

statically
and

dynamically

Proper
tire
balance
is

necessary
when

driving
the
car
at

high

speeds
Consequently
the
wheel
and
tire

assembly

should

be

properly
rebalanced
whenever

puncture
is

repaired

The
wheel
and
tire

assembly
becomes
out
of
balance

according
to
uneven
tire
wear

Severe
acceleration
and

braking
or

fast

cornering
is
the

cause
of
wear
on
tire

resulting
in
unbalance
of
tire
and
wheel

assembly

The

symptom
of

unbalance

appears
as

tramp
car
shake

and

steering
trouble

To
correct
unbalance

which

BODY

TRAMMING
SEQUENCE

The

tramming
sequence
will
varv

depending
upon
the

nature
and

IOl
atiun
uf
the

misaligned
area
Priur
to

performing
any

tramming
uperation
the
h

uracy
of

refereJlce

points
to
be
used

must
be

determined
A

measurement

that

originates
from
a
reference

point

included

in
a

damaged
area

will

produce
untrue
results

and

confuse
the
evaluation

of
the

underbody
condition

Unlike

the
conventional

type
of
frame

design
the
unitized

type
of

body
construction

seldom

develops
the
condition

of

diamond
in
the
floor

pan
area
as
a
result

of
front
or

rear
end

collision
Therefore

underbody
alignment

checking
can

usually
originate
from
the

body
floor

pan

area
If

inspection
indicates
that
these

locations
have
been

disturbed

and
are
not
suitable

for

measuring
one
of

the

undamaged

suspension
locations
should
be
used

as
an

initial

reference

point
If

a
rare
situation

should
exist

where
all
of

these
lucalions

are

not
suitable
as

reference

points
repair

operations
should

begin
with
the

body
floor

All
