Ford Mustang rear end leaking at the driveshaft yoke on Ford Mustang

Some Ford Mustang owners report experiencing leaks from the rear of the driveshaft at the yoke, which is distinct from leaks at the front end. This issue typically involves the flange at the rear of the driveshaft, necessitating the disconnection of the driveshaft to replace the seal. Owners may need to remove the nut securing the pinion yoke to the pinion gear, torque a new nut to specific ft/lbs, and ensure proper reinstallation by marking the relationship between the rear driveshaft yoke and pinion flange before removal. Additionally, during the seal replacement, it is advised to inspect for wear rings or pitting and check for any slop or wobble in the components. The repair process generally involves removing the driveshaft and flange at the front of the differential, replacing the seal, and reassembling everything in reverse order.
