CHECK
The front camber and caster are not adjustable. Refer to
“Wheel Alignment Specifications” in this section. Jounce
the bumper three times before measuring the camber or
the caster in order to prevent an incorrect reading. If the
front camber or caster measurements deviate from the
specifications, locate and replace or repair any dam-
aged, loose, bent, dented, or worn suspension part. If
the problem is body related, repair the body.
REAR CAMBER CHECK
The rear camber is not adjustable. Refer to “Wheel
Alignment Specifications” in this section. If the rear cam-
ber deviates from the specification, locate the cause and
correct it. If damaged, loose, bent, dented, or worn sus-
pension parts are found, they should be repaired or re-
placed. If the problem is body related, repair the body.
REAR TOE CHECK
The rear toe is not adjustable. Refer to “Wheel Align-
ment Specifications” in this section. If the toe deviates
from the specification, check the rear axle assembly and
the wheel spindle on vehicles without an anti–lock brak-
ing system (ABS) or the rear axle assembly and the hub
and bearing assembly on vehicles with ABS for possible
damage.
