Concorde V6-2.7L VIN R (1998)
Index Rotor And Wheel Stud
Runout should not exceed 0.03 mm (0.0012 inch). If runout exceeds this specification, hub must be replaced. Refer to Transmission and
Drivetrain. If hub runout does not exceed this specification, install rotor on hub with chalk marks two wheel studs apart. Tighten nuts in the proper
sequence and torque to specifications. Finally, check runout of rotor to see if runout is now within specifications.
If runout is not within specifications. Install a new rotor or reface rotor, being careful to remove as little as possible from each side of rotor.
Remove equal amounts from each side of rotor. Do not reduce thickness below minimum thickness cast into the un-machined surface of the rotor.
Checking Rotor For Thickness
Thickness variation measurements of rotor should be made in conjunction with runout. Measure thickness of rotor at 12 equal points with a
micrometer at a radius approximately 25.4 mm (1 inch) from edge of rotor. If thickness measurements vary by more than 0.013 mm (0.0005 inch)
rotor should be removed and resurfaced, or a new rotor installed. If cracks or burned spots are evident, rotor must be replaced.
Light scoring and/or wear is acceptable. If heavy scoring or warping is evident, the rotor must be machined or replaced.
