strange.... 9.75 differential cover instead of 8.8?
quick question... i just finished replacing the differential oil and the cover (was badly rusted outside). But when i order the new cover online, the cover for my year/model truck was suppose to be an 8.8 with 10 bolts. after receiving the package, i notice that the one installed in the car was larger, and further inspection show me that the differential cover was a 9.75 12 bolts. long story short, i bought a 9.75 cover, perform the oil change, and all is good.
BUT, is the 2005 F150 Lariat suppose to have that? I notice that the rusted cover was also a replacement (with no magnet inside by the way), both things are kind of strange for 48k miles.
...my first guess maybe the previous owner hit the cover with something... in my inspection of the gears in the differential,
i also find a writing saying OK....
...my second guessing is that the previous owner replaced the axle... the brakes in the rear are also disc.. not drum as i was expecting....
