Diagnosing broken axle/blow diff

Hey all,

I have a 1995 IH 9200 T/A, only moves if the power divider is locked out, I have a few questions s about diagnosing this. It’s not making horrible noises so I’m hoping it’s just a snapped axle.

The issue should lie somewhere in the front rear, correct?

To check if it’s a broken axle would I only pull the ones on the front rear to look at them or do I need to look at all four?

If it moves with the power divider locked out that should mean the divider itself isn’t the culprit right?

If it is inside the diff I need to ID what rear end I have. The metal tag on it has number that’s don’t seem to cross to anything besides the gear ratio itself but has the International emblem on the metal tag. Where can I locate another number to know what it is? I have the trucks build sheet and it doesn’t mention what exactly it is. I think it’s an Eaton DS404 but I’m not certain.

Regards

 

Everything spins with the divider unlocked, so we will be looking at the rear rear then?

 

I don’t believe I have full lockers but I’m not sure how to tell if I have them, this is a new to me truck and I don’t think I’ve ever tan a truck that had them. How do I tell if I have full lockers?

 

Ah yes, no it doesn’t have those on the dash so no full locker. So I would imagine there is going to be some shavings even if the diff is good. I’m guessing these diffs are original and if they are they got almost 800k on them.

Wish I knew, can’t read the casting numbers and the metal tag is gone on the rear and has no useful numbers on the fronts tag. Any ideas how to ID?

No update but I can confirm both driveshafts spin with the power divider unlocked and the truck goes no where. I will update when I am able to get a look at it.
