Dana Spicer 683538 is a service carrier differential assembly for the S190 NS axle, built around a 4.56 gear ratio and a hypoid ring gear with an 18.500 outside diameter.

A differential carrier houses the differential and gearing that receive driveshaft power and share it across both wheel ends, so each wheel can turn at its own speed through a corner. Worn carriers tend to announce themselves with grinding or whining that changes with load and speed, metal flakes in the gear oil, or clunking when power is applied or lifted. Call us to confirm proper fit for your axle.
