Allright, I have a solid D44 that I'm getting ready to swap into my truck. I'm going to run the stock shafts until they break, but at that point I'm going to go with some aftermarket shaft.

My question is this: if I run alloy shafts with spicer 760 u-joints, will the u- joints protect my investment of the stronger shafts? I would rather have the u-joint be the weak link since they're cheap and easy to replace, but if the joint blows will it take the shafts with it? I know there is always the possibility, but are the odds for me or against me?

Ya, what he said.. plus if a joint lets go under torque you could loose a locker too. But dont be too quick to put down the stock 44 stuff. If your running no more than 36 or 37 and drive smart they should be ok. My 25 year old stuff lasted 2 years behind 300 hp and a 100:1 low range with 36's but one died the first trip out with 39.5s....
This is why all i am going to do is replace the u-joints before i put the axle in, i'm goign to milk the stock stuff for all it's worth. Then if i don't break anything i'm ahead $1000. I'm also just going to be running the trac lok out front, but if i lose that i have spare carriers and gear sets so no major loss.

So after that it's basically all or nothing. If everything is "bullet proofed", that'd push the weak link to the hubs. Is anyone running hubs breaking alloy shafts or are those mainly people running drive flanges?

The idea makes sense, but in the 26 years that this axle has been in existence, i'm sure the joints have been changed at least once. Besides, since i tack the caps in place i don't see this as being as big of a deal as if i were just using the C-clips. With my setup now I check the u-joints after every run looking for wlaking caps and missing clips, so it won't be any more effort after the swap.

Right now I know they turn freely, but i haven't been able to check them for slop or bad seals yet. That'll happen around oct. 1 (next time i'm home).
