Challenger V8-5.7L (2010)
On-vehicle rotor runout is the combination of the individual runout of the hub face and the runout of the brake rotor (hub runout can be measured
separately). To measure rotor runout on the vehicle:
1. Raise and support vehicle. See: Maintenance/Vehicle Lifting/Service and Repair
2. Remove tire and wheel assembly. See: Maintenance/Wheels and Tires/Service and Repair/Removal and Replacement/Tires and Wheels - Removal
3. Install standard wheel mounting nuts, flat side to rotor, on all studs (2). Progressively tighten nuts to 150 Nm (110 ft. lbs.).
4. Mount Dial Indicator C-3339A (1), with Wheel, 25w, or equivalent, to knuckle. Position Dial Indicator Wheel to contact rotor braking surface
approximately ten millimeters from outer edge of rotor (3).
5. Slowly rotate brake rotor checking lateral runout, marking the low and high spots. Record these measurements.
6. Check and record runout of opposite side of rotor in same fashion, marking the low and high spots.
7. Compare runout measurement to specifications.See: Specifications
If runout is in excess of specifications, check the lateral runout of the hub face. Before removing the rotor from the hub, place a chalk mark across both
the rotor (1) and the one wheel stud (2) closest to where the high runout measurement was taken. This way, the original mounting spot of the rotor on the
hub is indexed.
8. Remove the rotor from the hub. See: Service and Repair/Removal and Replacement/Brake Rotor - Removal
