And wheels with more offset...

Whats offset mean?  Sorry I'm kinda new to this Jeep thing...

[Jesse-James]

Where the mounting surface is in relation to the center of the wheel.

Can it break of course can a Dana 60 break you bet.

It better not.......

Remember Tinknocker that was with us at The Cliffs? I watched him bust a 60 shaft into 4 pcs with his 4 banger, it happens.

Well...if someone was going to break one, it would be him.....and I know you are not comparing my wheeling to his...

Kinda hard to break something wheeling the Michigan highways Moz

True...and probably didn't have a chance a The Cliffs....this guy had a hardcore 4-banger though...

remember that most people dont buy a new Dana 60 when they add them as a upgrade, due to cost most buy used older Dana 60's. I found My Dana 60 used for 50 bucks and in not bad shape, needless to say near to impossible to duplicate that deal haha. 
With older axles the metal in the axle shaft can sometime become weakened from time and hard use, now i completely rebuilt my 60 not everyone does that due to cost (way over 1000 bucks) they run em as found. This is in most cases why big axles break in situations that one would think they cant break.

Actually it's usually when the driver doesn't let up when the rig starts hopping. All the weight comes down on one tire with full throttle and when it get traction *snap*

That or kind of get a wheel caught and then romp on it to get it to move seen an axlle snap like that with a good lowrange you can put an awfull lot of torque to the wheels

Even with that situation there is no way that a rebuilt Dana 60 would have any problems with a 4banger even running large tires, unless it has some dam big gear reduction or huge forced induction. The T-case would fly apart long before the Dana 60 would. I run a Dana 60 front in my 1 ton Chevy with 37x13.5-R17's, it is fully locked with 5.13 gears, and I have tried to break it with a V8 with no luck at all even with the above described situation.

[Jesse-James]

Seen it with my own eyes..... Hard to break, yes. Impossible, no.

And it was not because the shafts were "old" both rear tires caught air from hopping and the right rear came down between two rocks and was forced to stop with full throttle still applied.

Carb'd 2.5L, AX15, 207 case, 5.13 gears

Play this vid, at 5:00 he's doing the same thing. No breakage this time cause the wheel didn't get trapped like it did when it broke, but you get the idea.

Thus why a 14bolt makes a better rear lol
I didn't know we were talking about rear axles but there are light duty Dana 60 rears that are out there to, the fronts tent to be bigger unless they are really old with the stepped down axle shafts. In kinda thinking that the 60 was one of the smaller axle shaft ones out there, more likely to have them break rather then the 35 spline rear Dana 60s.

That is what I'm affraid of each time I see a undercut. With over 200:1 and 37's the 30 spline shafts in the rear can snap pretty easy(D44). Even though they are cryo'ed cromo's.
Like others have said, bouncing is another way to snap stuff. Seems like it's the 3rd bounce then KA-BAM!
