I was getting about 3 years out of my 5-760's. But that isn't telling anyone what they need to know about life expectancy.

Thoughts on 1350 u-joint in axle shaft?

True, I know I didn't really know how to ask the question.. miles, abuse, conditions, location, tire size, drivetrain, etc all are factors. I was trying to figure out if people were saying they don't break but they are replacing them every 4-5 runs.
Your question was fine. If I were to guess, I was getting about 20k miles out of mine. This would be mostly daily driving miles and wheeling what I wheel.
OP
I oddly just found my own post on this. I ended up sticking with 5-760's and chromo shafts.
Today I had my first failure in 20 years. Luckily shafts were fine and got it replaced and back on the trail in 15 min
Looks like the joint was already cracked and this just finished the job. Joint only had 500km on it.
Almost everyone on the run had rcv shafts so I might make that swap.
Edit: I also will highly consider the 1350 option. I didn’t note it because I was already told there was no eta on them being back in stock but that wasn’t from the manufacture just my parts guy who was on the run and called into the shop. Plan to call manufacture on Monday.
But I might also stick with just the 5-760s since it’s looking like this wasn’t a true spicer.

Happy to hear you got back on the trail without too much trouble.
Folks in here have listed the Pros/Cons of going with RCV vs Joints. My limited recollection is that RCVs may not do so great if you play in the water/mud, but I have no experience and may have not recalled that info correctly.
I played in the rocks last year without any issues, but I'll consider pairing RCVs with my 30-spline Yukon Hubs if I ever have issues. I won't be able to run the larger joint with my hub kit's outer shaft, but I'd go with a larger joint over RCVs if both choices were equally available to me.
I'd strongly encourage you not to do that. The reason is RCV uses the smaller bell that fits through the smaller older 44 and 30 knuckles. That makes it a fair bit easier to break than the one they supply for the TJ Unit Bearing knuckles.
I have R&G inners paired with outers from Yukon's 30-spline hub kit (requires 5-760x).
Just realized that’s incorrect. My apologies.
R&G non-domestic inners weren’t available and had been holding up my regear, so I ended up going with Yukon inners as well.
I have US sourced R&G axles in the rear.
