SERVICE DIAGNOSIS
12.
FRONT END NOISY
A certain amount
of
looseness
is
designed into
the threaded bushings
of
front suspension link-
age
to
prevent binding
of
joints under deflec-
tion. Unless they cause noise
or
unstable steer-
ing, these parts should
not be
replaced. Proper
lubrication, however,
is
essential.
It
should
be
remembered that threaded bushings require
more clearance than
a
smooth
pin and
bushing
type joint; actually only
the
knife-edge
of
the
threaded pin operates
in
the "V" shaped thread
cut
in
the bushing,
as
shown
in
Figure 1. With
the weight
of
the car on the bushings, the knife-
edge bears against
the "V"
until there
is suf-
ficient wear to permit endwise movement
of
the
threaded pin in the bushing. This condition will
cause
no
harmful effect except
an
increase
in
noise on rough roads.

TIRE WEAR
Certain types
of
tire wear
are
caused
by
im-
proper adjustments
or
condition
of
the
vehicle
while other irregular tire wear
is
due
to
poor
driving habits
or
improper tire inflation. Rapid
acceleration, sudden severe brake application,
turning corners, rounding curves
too
fast,
or
sharply; along with high speed driving will con-
tribute to increased and uneven tire wear. Other
types
of
tire wear due
to
improper adjustment
of
the
front suspension
or
other conditions
of
the vehicle
can
be
corrected
by
checking
and
correcting front suspension alignment.
