Where can you find parts diagram for 1978 Ford F-350 4x4 front axle?
I would recommend getting a Chilton Ford truck manual that is
very in depth and, more than likely, have your answers you're
needing. I found the book you would be needing at
http://www.auto-repair-manuals.com/auto.html . First, click on
"Ford Truck", then click on your year your looking for, " 1978 ".
There are several manuals you can choose from. Good luck in finding
what you're looking for and I hope this helped!
