Hi Lester and Kent,
These rotor to hub bolts are "place" bolts and are of a special design to
allow heating and cool down without getting loose. You should NEVER use ANY
grade 5 or 8 bolts here and NEVER use a lock washer.
Use Place bolts only. They were developed for steam engines and are perfect
for this application. You can spot them easily as the head has 6 sort of
pie shaped wedges on the head.

vibration and clunking noise that came from loose bolts that holds the rotor
to the hub! They are the black, strength rated bolts that sit down in
countersinks... I forget what they are supposed to be torqued to but it was
a bunch! If they loosen up, the wheel's rotation causes them to shift and
clunk at low speeds and to vibrate like the dickens at higher speeds.
