Product Details

Raybestos Element3 rotors are built for direct replacement use where correct dimensions and consistent braking performance matter. This 66670FZN rear rotor matches the listed Ford F-150, Ford Expedition, and Lincoln Navigator fitments, including 1997-2003 Ford F-150 rear, 1997-2002 Ford Expedition rear, and 1998-2002 Lincoln Navigator rear applications with the specified wheel-stud configuration. This part cross-references Continental 66670 for the same application.

Common Brake Issues This Rotor Can Address

• Rear brake pulsation caused by rotor wear or thickness variation
• Corrosion on exposed rotor surfaces
• Noise from worn or uneven braking surfaces
• Reduced braking consistency from a rotor at or near discard thickness
• Fitment problems when replacing a drum-in-hat rear rotor with the correct dimensions

Installation Notes and Tips

• Verify rear fitment by year, make, model, and wheel-stud configuration before installation.
• Confirm rotor thickness and discard thickness against service specifications during brake inspection.
• Inspect pads, caliper hardware, and parking brake components at the same time to help restore even braking performance.
• Clean the hub mounting surface before installing the rotor to reduce runout concerns.
• Follow the vehicle manufacturer’s service procedure for rear brake service and torque specifications.

Quality Assurance

Raybestos Element3 coated rotors are engineered as direct replacement brake components with application-specific dimensions for the listed Ford and Lincoln vehicles. The coated finish helps protect exposed surfaces from corrosion, supporting long-term service in rear brake applications.
