Leaking rear differential seals on 4WD models
if after a long trip you notice that the rear differential has oil leaking out of the drive shaft or the half shafts seals, don't panic. Clean up the entire differential with brake dry clean or electrical contact cleaner spray, be generous around the drive shaft lip as it can hold some oil. Then take a look on the back cover plate for a valve that should move a bit, if it doesn't, remove the valve with a 13mm wrench and give it a good spraying with the brake dry cleaner in both ends and exercising the valve until it clears the blockage gunk. The valve is not shown in the Ford Maint manual, but it is in the Mazda Tribute maint manuals and parts catalogs. The valve is a one way pressure relief , lets air out, prevents air and water from getting in. Check the oil after re-installing the valve. The oil should be ok and just level with the bottom of the inspection plug which just uses a 3/8" drive ratchet to remove. Drive a couple of hours and if nothing is leaking, you're good to go.
