Great link Pele. Saw that too in my search for that elusive book.
Lots of info in there! But really, maybe a little too much info? And none of it I am looking for.
I just have a leaking rear differential input shaft seal.
Can't find the damned breather on the differential to see if it's clogged, (Causing the leak with air pressure inside the case from heat expansion.)
I would love to have a diagram to be able to pinpoint it visually.
And would also love to have the rest of the book saved for many other future uses I have yet to discover.
Location: Behind a workbench, repairing FC Electronics.
Manuals for other vehicles equipped with the Ford 8.8" rear will work as well.
(Crown Vic/Grand Marquis/Continental, Explorer/Mountaineer, Thunderchicken/Cougar/Mk VIII, etc...)
Rear diff breathers can be anywhere on the axle shaft or diff housing. Looks like a thimble just screwed into the side of the housing randomly (Obviously pointing up.) Just look like a nub sticking up.
Some vehicles have them relocated on tube and attached high up on the body so that the vehicle can go through deep water. Look for a tube to nowhere.
I went over the whole thing for 10 minutes yesterday and gave up the search. (I do know what they look like)
Brought my search to the internet and came up empty again after another 2 hours.
What if the breather is fine? Then I have to take it apart to replace it. But wait! I also need a FSM for proper remove/dismantle/reassemble/reinstall procedures/torque specs/etc!
If only I had an FSM, I would have the damned thing fixed by now.
