Ok. I give up. I am trying to pull the differential on my 1973. It's the typical 9". Pulled the axles. I removed the driveshaft. Took off all the nuts around the housing. Took a block of wood and a hammer to loosen it so I could let the oil drain. No go. I have tried everything short of using a sacrificial screwdriver because I don't want to gouge the sealing surface. Any ideas or suggestions will be appreciated. I don't want to pay a shop to do this but I am about THIS close......Pat Price

Bigger hammer and the same block of wood would be my approach. Sledge hammer if need be.

what about putting a jack under the front of the center section and jacking it up just enough to break the seal?

Try using a 1" putty knife. Tap it in all around wherever you can get access.
Keep two nuts on the end of two of the studs to prevent a sudden release of the pumpkin.


The jack under the front yoke is a good trick too -- especially once you've cracked the seal using the knife.

I have tried the jack trick. I will be trying the putty knife next (after a long coffee break).

I once struggled with a 9 inch trac loc in a Bronco found in a part yard. Sucker was double nutted on the top, to hold a brake line.

I have used the jack trick with success too.

comealong from the trans mount to the pinion yoke. Pops it right off, provided you have all the nuts off.

WIfe's '70 Mach was a pistol to break loose. I had the floor jack on the nose of the pinion. Nada.... Was gone into the garage to get something else to try when I heard a loud bang when the gasket finally let go...

Oh, BTW, did you remove all of the washers from under the center section nuts first? They are soft copper and tend to 'flow' into the hole and seal the threads. You generally have to chisel them off...

Now there is a thought. I'll report back after I check this out.

BINGO! We have a winner! Thanks all. It drains as we speak.......Pat
