Haven't done a whole lot of price shopping... but seems like:
Yukon: $734 Uses 5-760X Joint limited lifetime warranty
Revolution: Guess Jeep only? Could have sworn I saw it for Chevy D44... must have been a mistake.
Ten Factory MG22172: $568 Uses 5-760X Joint. 10 year warranty
G2 98-2033-006: $700 Uses 5-760X Joint 10 year warranty
Then there is RCV Ultimate: $1,349 They have CV joints that are supposed to be twice as strong as a standard U joint even at extreme angles. But... $$$$$$

It looks like all the warranties also state that the warranty covers up to a 35" tire- which is what I'm running. (* the RCV warranty is up to a 40" tire)
And as far as I can tell the warranty doesn't include the U joint. And I guess after getting stronger shafts then the next thing that can go is snapping a U joint... especially if the front wheels are turned all the way to one side or the other. The U joint is weakest in that position.
That then brings up the next point. Instead of the 5-760X joints how good are the Yukon Super Joints or the CTM joints. Both say "not recommended for daily driven use". Neither of these use roller bearings. Instead it is a super tight fit with bronze sleeves in the caps and full circle snap rings. The caps have needle zerks in them. They need to stay lubed (which I guess is too often for daily driven rigs). Now here is my question- I have hubs. When "daily driving" my truck the joints won't be turning, right? So only lube them after running 4wd after a hard trip?
Yukon super joints: $235 each
CTM joints: $267 each.
Yeah, getting expensive in a hurry... Basically I'm thinking $1,038 for the Ten Factory axle shafts and the Yukon super joints. But at that price it puts it in pretty close to those RCV Ultimates...
I've never messed with axle shafts before so this is a new area to me. I know of the theory behind them. This was part of the reason I chose the Eaton Trutrac in the front instead of a locker. It is not as stressful for the front axle. (and I can still turn). Along with the differential I've also invested in some Yukon hardcore locking hubs. At this point I already have $850 into my D44.
I've never broken a front axle shaft but did break a 12 bolt rear axle shaft in my old truck with 33" tires. Not fun.
I'm wanting to replace the axle shafts at the same time I buy and install Reid knuckles for it. These are stronger than stock and will allow crossover steer.
