The pinion seal sits in the rear differential housing where the pinion exits toward the driveshaft connection. The seal body stays stationary while the pinion assembly turns inside it. It helps hold the differential's lubricant in and keep contaminants away from the internal components.
Signs this part may need replacing: fluid seeping or dripping from the front of the rear differential near the driveshaft connection, oily residue on the housing, or a differential that repeatedly runs low on fluid. Diagnose the source of the leak before replacing the seal.
