do I have a 9" diff
this is a '82 F-150 ........ I need to know if it has a 9" rear diff....
there is no tag on the diff but on the door says axle 16...... any help would be nice............ thanks...
8.8 has a tin inspection cover on the rear with 10 (?) bolts. The 9" has the differential carrier that bolts in from the front. The rear cover is relatively smooth.
Here's a 9" https://www.ford-trucks.com/article/...ear_Setup.html

Not sure what code 16 is. It would be a non-limited slip, but I don't know the ratio. Maybe someone else knows.
Edit - Found a list. Looks like a 3.73 ratio. http://www.drivetrain.com/Fordtrkratio_posidata.html
