Signs a pinion bearing race may need replacing include a whine or growl from the differential that changes between acceleration and coasting, or a pitted or spalled raceway found during inspection. Diagnose the cause before replacing parts. If the race is worn, it is common practice to replace it together with its matching cone and to follow the vehicle service information for pinion setup and preload.
