Careless Handling Of
Car Is Common Cause
BY {. X. HAusT

Satisfactory operation of the mo-
tor car is impossible without accu-
rate alignment of the parts. This
will probably be strange doctrine Tor
most car owners who may never have
heard OF alignment. Nevertheless II
is absolutely true. The efficient ana
satisfactory operation of the various
mechanical units of the chassis de-
pend entirely on those units being cor
rectIy aligned Let them set out of
line and all sorts OF trouble immedi-
stely follows. Gear teeth break, in
tense friction is set up and minor ills
uuickly grow into major failures un-
fiji the car must be extensively over
hauled to put it on the road again.
The car owner will readily under
stand that when the vehicle first
comes from its maker all the various
parts are properly aligned and so
run perfectly When the car is care
lessIy handled this perfect alignment
and balance is quickly lost and trou-
bic begins. If the car owner VIII de-
vote the same attention to MAINTAIN
ing correct alignment that he is ad-
vised to bestow on fabrication, his
familiar troubles will never even be-
gin. Consequently he should take
this warning to heart.
One of the commonest cases of mis-
alignment is that of the front wheels,
which is Immediately made evident
in an excessive tire wear which may
result in the destruction of the cas-
irgs in a few miles of running. The
alignment of the front wheels is de-
termined by the condition of the
steering system. the front axle, the
bearings and various minor parts. 1t
is quite possible to throw the front
wheels out of line in a hard bump
against the curb,s The car owner
ought to check up. or II he cannot
10 it himself, have the service sta
tion do it. the alignment of the wheels
at least twice a year. If the wheels
have been subjected to a severe bump
which might throw the wheels out
OF line, the checking up should be
carried out regardless of any set time
for the operation.
1t is possible also for the rear
wheels to get out of line, depending
on the condition of the rims. the bear
ings. the axle. etc. Trouble deyel-
oping in the rear axle is likely to
throw the wheels out of line. For in
stance if the rear axle is not prop
erly fabricated, mechanical derange-
rnents are inevitable and these tend
10 throw the wheels out of line 1t
is quite possible by careless driving
to throw the rear axle out of line
For instance if the car is started with
the hand brake set, the differential
ring gear or an axle shaft may be
very likely broken. The strain has
simply bern too much for the parts
and the weakest of them has snapped.
If the brake is applied while the
wheels are in the air. as they are
likely to be much of the time when
the car is going over rough road sur
face. the wheels will be locked when
the strike the ground and the result
will very likely be snapped driving
pinion. These are simply instances of
careless or actually bad driving that
are very likely to throw the various
PARTS out OF alignment and make sat
isfactory operation impossible; ana
be it noted they are simply couple
of instances from many similar trou-
bles that may occur.
Let us examine briefly some Of the
