CHASSIS SUSPENSION
SERVICE PROCEDURES 7 - 3 7
g. Checking Theoretical King
Pin Inclination
CAUTION: When checking theo-
retical king pin inclination, car
must be on a level surface, both
transversely and fore and aft.
It must be measured at curb
height. See Figure 7-22.
With camber known to be within
specified limits, theoretical king
pin inclination should check with-
in specified limits given in Fig-
ures 7-37 and 38.
If camber is incorrect beyond
limits of adjustment and theo-
retical king pin inclination is cor-
rect, or nearly so, a bent steering
knuckle is indicated.
If camber and theoretical king pin
inclination are both incorrect by
approximately the same amounts,
a bent upper or lower control
arm is indicated.
There is no adjustment for theo-
retical king pin inclination as this
factor depends upon the accuracy
of the front suspension parts.
Distorted parts snouid be re-
placed with new parts. WARNING:
The practice of heating and bend-
ing front suspension parts to cor-
rect errors must be avoided as
this may produce soft spots in the
metal in which fatigue and break-
age may develop in service.
