Rear Hub Bearing

Bearing malfunctions normally will be obvious at disassembly. Pinion bearings make a high-pitched, whistling noise, usually at all speeds. However, if there is only one pinion bearing that is malfunctioning, the noise may vary in different driving phases.






If bearing cup is spalled (A) or bearing roller(s) are spalled (B), replace the bearing.
