In a differential, the pinion bearing supports the pinion shaft as it drives the ring gear. In a manual transmission, the input shaft bearing supports the input shaft that receives power through the clutch. Signs this bearing may need replacing include a whine or growl that changes with vehicle speed or throttle. On the transmission side, a rumble in neutral that goes quiet when the clutch pedal is pressed can also be a sign. Gears, seals and other bearings can make similar noises, so diagnose the source before replacing. Follow the vehicle service information for installation and setup.
