Ring and pinion look grate! tested posi before removing, still in good shape. Oil was super clean. but found this in the bottom. put a pen next to it to show size.

Yup that sure look like it!
Guess i'm rebuilding my clutch pack after all.
 
I'm guessing they got a lil thin and one of them popped down out of the slideways.
Or incorrect assembly, but that's a stretch.
Well so is the first,so
IDK

That's the question. It was working just fine I put a torque wrench on both axle and they held to 150 foot pound(didn't want to torque my lug nut any tighter than that.

Looking on doctor diff sight. They recommend the motorcraft limited slip additive. So that's what i will use. Have Always used the MP additive.

Slip and grip of the clutch pack is what i think would cause it.
Maybe a different additive while work better.

If you dare to smell thatchit it all smells the same, so................. Ima thinking they might all be, the same. I use the GM stuff, but I don't put it all in, lol.
I set my cone-types up at 120ftlbs turning torque; not breakaway torque, and I do it with a stub-axle in the vise and a stub axle on the T-wrench end that has a big-old nut welded onto the end. At 100 it will slip if both wheels are not on the same surface. At 150 it becomes a spool. I use select-fit Ford side-gear washers to set the preload, in concert with additional springing if necessary.And sometimes,I put some heavier springs in there, but I don't recall what they were out of. I set the clearance at the bottom between the cones and the case to .080 minimum by lathe cutting the cones off. This gets me another 100,000 plus miles out of them.

On the clutch-types, the engine torque runs the cross-pins up the ramps, so until the clutches wear-out, I get what I get. Sometimes put a lil more spring in them

I like them to slip around turns at normal cornering power. I hate it when they act like spools.

LOL. Do you remember what "Direct Connection",back in the day, called it?????? LOL
 
It's actually very common
You see, everything has it's strong sides, and weaknesses
Even though the sure grip can take a lot of physical abuse, they do not hold up to mental abuse at all

So when you called it a "posi" the sure grip said "fine, then I'll act like a possy " and blew it self up

Pretty common, really
:poke:

:mob: :rofl:

I will sure try to be more Grip..ping with the rest of my posts:D
 
Like chaulk on a blackboard, but I’m in therapy for it. I’m sure if we were Ford guys it would be.......well whatever ford calls it, never care to learn. :)

Nobody knows what it was called????
What did DC called the sure grip additive.
 
Wow there is a few out there...
But i do believe it was called "sperm whale oil"

I wanted to take a picture of the paragraph where it said that.
Pulled out my old, taped together book, but couldn't find it with a quick scan thru the pages. ( 1980 addition)
 
OK, now.
I plan on rebuilding my pos....sorry bad habits are hard to change:p. My sure grip tomorrow.
I have two sets of them, one has a friction material on it and the other one is just plain steel to steel. Which one would you use?
 
The 7000 rpm neutral-drop , half and half ones
back in my younger days that old 318 would float the valve long before i could hit 7 grand. I would have been there all day with my foot to the floor.(200,000 mille 318 with a 2.76 gear in the rear.):lol:
 
That brings up another thought.
anyone have problems with Synthetic gear oil and friction modifiers aka sure grip lube?

Yeah the springs on mine were done at 4800. I put some other springs on that I had laying around, and it went 5400 without complaint. I think they mightabin 360 2-bbl springs.
