AXLE HOUSING ALIGNMENT
If rear tire wear indicates that the axle housing may be
bent, the alignment can be checked as follows:
1. Back the car squarely onto an alignment machine.
2. Compensate for wheel runout the same as for checking
front wheel toe-in.
3. Check camber reading which should be 1/4" negative
to 1/2" positive.
4. On B Series, check the amount of toe-out which
should be 0" to 1/16".
5. On A and G Series, check the amount of toe-out which
should be 3/64" to 5/32".
NOTE: Due to the fact that the car is backed onto an
alignment machine, the actual toe-out will be read on the
scale as toe-in. However, if the toe-out is checked with
a tram gage, disregard this note.
6. If a tram is used for checking toe-out, it will still be
necessary to perform Steps 1 and 2 in order to check camber.
The necessary
straightening
operations may
be
performed using frame straightening equipment without
removing the axle housing from the car. This procedure will
allow checks during the straightening operation to determine
when the housing is within the prescribed limits.
