Oil leak at differential Ford Escape
Ford reports that a deformed pinion seal can cause oil leaks at the differential on the Ford Escape. They’ve redesigned the seal and the new part is YL8Z-4NO46-AA. Scratch index marks on the driveshaft and yoke. Then remove the driveshaft. Then remove the pinion nut and mark alignment scratches on one of the yoke splines to the corresponding spline on the pinion gear. Remove the yoke. Then yank out the damaged pinion seal. Use a cupped driver to install the new seal. Reinstall the yoke, making sure it’s aligned. Then install the pinion nut and torque to 180-ft/lbs. Then align the driveshaft to the yoke and tighten the nuts to 17-ft/lbs.
