CAUTION: The rotor runout specification must be met to assure proper brake performance without premature vehicle return with shudder, pulsation or roughness complaints.

1. Do not remove wheel and tire. Tighten lug nuts to 115-142 Nm (85-104 ft. lbs.). Raise and support vehicle.
2. Assemble disc rotor and ball joint gauge and extension. Install spherical tip on extension.
3. Locate an opening on inboard side of rotor between disc brake caliper and dust shield.
4. Clamp Rotunda Disc Rotor and Ball Joint Gauge 134-R0199 or equivalent on vehicle making sure flexible indicator arm and probe tip does not touch dust shield or tire.

NOTE: Do not apply any lateral force on wheel while rotating. Record total indicated runout.

5. Position Disc Rotor and Ball Joint Gauge so dial indicator tip is at least 5 mm (0.196 inch) from outer edge of rotor.
6. Rotate wheel six revolutions.
7. If the runout is not within specification, remove the wheel and tire assembly.
8. Using touch-up paint, mark the rotor and one wheel stud. Remove rotor. Measure the hub flange mounting face outside of the stud circle.





9. If the runout of the hub flange exceeds specification, install a new hub and bearing assembly and repeat flange face runout measurement. Refer to Transmission and Drivetrain.
10. If the runout of the hub flange is within specification, reindex (so paint marks are not aligned) the rotor to the hub, reinstall wheel and repeat the measurement. Wheel hub runout must be less than 0.06 mm (0.002 inch).
11. If the on-car-mounted hub and rotor still exceeds the specification, replace the rotor, repeat the runout measurement and re-index the rotor if necessary.
12. Prior to reinstalling the rotor, clean the hub face and backside of rotor hat section of contaminants. Apply High Temperature Nickel Anti-Seize Lubricant. Install rotor.
13. Reinstall the caliper, rotor, and tires and wheels.
14. Road test vehicle.
