both the rotor and one wheel stud on the high side of
the runout. This will ensure that the original location
of the rotor in relation to the hub can be retained
(Fig. 14). Remove rotor from hub.

Thoroughly clean the front surface of the front
hub. Then 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 posi-
tion stem outside the stud circle but inside the cham-
fer on the hub face (Fig. 15). Clean hub surface
before checking.
Lateral runout should not exceed 0.08 mm (0.003
inch). If runout exceeds this specification, the hub
must be replaced. See Suspension Group 2. If lateral
runout of the hub does not exceed this specification,
install rotor on hub with chalk marks two wheel
studs apart (Fig. 16). Tighten nuts in the properse-
quence and torque to specification. Finally, check lat-

eral runout of rotor to see if lateral runout is now
within specification.
If lateral runout is not within specification, install
a new rotor or reface rotor, being careful to remove
as little rotor material as possible from each side of
rotor. Remove equal amounts from each side of rotor.
Do not reduce thickness below minimum thickness
marking cast into the un-machined surface (Fig. 17)
of the rotor .
Thickness variation measurements of the rotor
should be made in conjunction with the lateral
runout measurements. Measure the thickness of the
rotor at 12 circumferentially equal points with a
