Differential bearings support the rotating parts inside the axle so the ring and pinion gears can turn and mesh as the vehicle drives. Signs they may need replacing include a whine, howl or growl from the rear axle that changes with speed, or noise on acceleration or deceleration. Other worn parts can make similar noises, so diagnose the cause before replacing parts. Ring and pinion setup calls for precise bearing preload and gear backlash adjustment. Follow the vehicle service information for the procedure and specifications.
