Technical Rear Diff ID

I know this is elementary to some but I'm far from an expert. What differential is this?







Thanks!

 

Looks like an 8" Ford.

 

looks like a 9" ford.

A picture from the front would clarify. If the lower two nuts that hold the center into the housing can't be unbolted with a deep well socket, it's a 9". If they can, it's an 8". Looks like a 9 to me...

 

If you can put a 3/8" drive 9/16" deep socket on all the nuts it's an 8". If there is a lower nut you must use a Box end wrench on it's a 9". Kind of hard to tell that from your photo's.

the hump in the back of the housing is something you see on the 9" but not on the 8". And the oval shape, vs a more squared off shape on the 8".

 

Thanks for the input guys. I'll take a look at the front of the diff. Was reaching under the car to get photos.

 

8"



9"

 

Perfect! Thanks!
