DIAGNOSIS AND TESTING (Continued)
Fig. 19 Checking Rotor For Runout
Fig. 20 Marking Rotor and Wheel Stud
Install Dial Indicator, Special Tool C-3339 and
Mounting Adaptor, Special Tool SP-1910 on steering
knuckle. Position stem so it contacts hub face near
outer diameter. Care must be taken to position stem
outside the stud circle but inside the chamfer on the
hub rim (Fig. 21). Clean hub surface before
checking.
Runout should not exceed 0.08 mm (0.003 inch). If
runout exceeds this specification, hub must be
replaced. See Suspension Group 2. If hub runout
does not exceed this specification, install rotor on hub
with chalk marks two wheel studs apart (Fig. 22).
Tighten nuts in the proper sequence and torque to
specifications. Finally, check runout of rotor to see if
runout is now within specifications.
If runout is not within specifications. Install a new
rotor or reface rotor, being careful to remove as little
as possible from each side of rotor. Remove equal
amounts from each side of rotor. Do not reduce thick-

ness below minimum thickness cast into the un-ma-
chined surface of the rotor.
Thickness variation measurements of rotor should
be made in conjunction with runout. Measure thick-
ness of rotor at 12 equal points with a micrometer at
a radius approximately 25 mm (1 inch) from edge of
rotor (Fig. 23). If thickness measurements vary by
more than 0.013 mm (0.0005 inch) rotor should be
removed and resurfaced, or a new rotor installed. If
cracks or burned spots are evident, rotor must be
replaced.
Light scoring and/or wear is acceptable. If heavy
scoring or warping is evident, the rotor must be
