the remaining intermediate elements (spacers).
In all cases, take care not to damage the hub and
its teeth. Remove and discard the intermediate
elements (spacers) and retention clips attaching
the rotor. Discard the rotor.
5.7.9 Following industry standards, clean and inspect the
hub before installing the rotor. Look for corrosion
and/or damage to the hub and inspect the wheel
speed tone ring. Where necessary, consult the hub
manufacturer's guidelines for more details.

ROTOR INSTALLATION
5.7.10 See Figures 87 through 91. Place the rotor into
position on the hub. Install the new intermediate
elements (spacers) as shown in Figure 89. With
all the intermediate elements (spacers) correctly
inserted into position, verify that the gap between
the intermediate elements (spacers) and the wheel
hub does not exceed 0.004 in (0.1 mm). If a gap is
found that exceeds this maximum value, verify the
installation of new intermediate elements (spacers).
Replace the wheel hub if the excess gap cannot
be corrected with proper installation of new rotor
retaining hardware.
