What's the difference?

On ice/snow covered public roads im thinking stock open diffs is as good as it gets. If you need more traction then studded tires or better yet chains are the answer.

It looks like Detroit Locker in the 14BFF and a Detroit Tru-Trac in the D60 !!

Dumb questions:

This wouldn't hurt the axle?

And I'm assuming you're referring to a spool?

Not a dumb question at all.

I wouldn't make a habit of driving around that way nor would I intentionally wheel in that configuration given other options but you'd at least be able to turn on slippery/icy roads that way.

Do you have lock outs or drive flanges on your spooled D60?

Lock outs.
I'd like flanges if I had a selectable though.

Then your front diff. acts like an open diff. with the front axle unlocked, right?


Also:
Would snowchains help with keeping traction and keep from sliding sideways in the snow when a front diff has a spool?

If your going to drive in 3 wheel, make sure you have the short side free.

Interesting...why?

[hilbilly]

We brake 4340 dana 60 and ff14 axles two or three times a year. welded rear and spooled front, drive flange long side and lock out shortside.
The short side axle will break first, because it's short and can't take the twist as well as the long side. You will break the shaft, ujoint or stub.
The major stress on the axle shafts come from turning. When the front is assembled you need to index the joints so the stub shafts move the same when turning this takes the stress off the joints. If you release one side and drive, then lock it back in again the joints are nolonger index'ed and this causes more drive line bind. This will happen with a locker or spool, I don't like lockers, when you turn and hammer 'em the overload one side for a milla sec. and snap ****.
Sorry for ramblin.......

What does this mean; 'index' ?

[hilbilly]

This is very important when it comes to fully locked front axle shafts. Both wheels are mechanicaly connected. so when you turn your wheels you want the joints on each stub shaft to mirror each other. Same as drive shafts. the ujoints/yoke combo on each end of the shaft need to be indexed so they move in the same direction.

This shaft is correct. If you turn the slip shaft 90 degress it would be wrong, apply this mind set to your front axle shafts. You need to also make sure the axle housing yoke and t-case yoke are alined and the parts are moving in the same direction.

Can't happen with a spool, both axles are engaged into the spool when installed and can't change from that point on.

Lockers, sure, axles engage/disengage at different intervals.

[hilbilly]

two many thoughts going on in my head. i should only type three line posts. When you assemble a spooled front, like installing drive shafts, make sure to index the joints.

Wow!

Excellent, and important, info here!!
