Fig. 17-Bent Housing
Housing "A" shown in Fig.
17 is a diagrammatic sketch
of a housing bent or sprung through accident.
The
differential carrier face was moved back from its original
position shown by the dotted line.
This change in
alignment was the result of contact by an obstruction with
sufficient force to bend the housing.
Housings like this
will be responsible for repeated axle shaft or differential
failures.
The misalignment must be corrected. This may
sometimes be accomplished by straightening; however,
unless properly done by an experienced worker, the
spring may come in again.
Housing "B" shown in Fig.
17 was bent by excessive
loading.
Note how the center, as shown by the dotted
line, was sprung from its original position.
Repeated axle
shaft failures and excessive tire wear will occur with
housings in this condition.
Bent in this direction, they
cannot be satisfactorily straightened, but must be
replaced.
Overloading causes housing deflection.
Since housings
will recover from a certain amount of deflection, if it is not
sufficient to produce a permanent set, trucks frequently
operate with a temporary spring in the housing which will
be enough to create axle shaft failure.
The same part
checked unloaded will seem to be in proper alignment.
