Differential bearings support the gear set and help it turn smoothly under load. Signs that these bearings may need replacing include a whine or growl from the rear axle that changes with vehicle speed, or roughness felt through the driveline. Other drivetrain faults can make similar noises, so diagnose the cause first. If worn differential bearings are the cause, this kit is designed to replace them.

Rebuilding a differential means setting bearing preload and gear backlash to the specifications in the vehicle service information. Installation by a technician with differential setup tools is recommended. See the "Vehicles it fits" section for engine details on each listed vehicle.
