Can’t even believe in the almighty RCV’s ???? Is that a front or rear shaft?

Rear
Unfortunately after getting out I found that I only had power to one rear wheel even with the locker. I think it’s why I got into the jam I was in 
After getting it back to camp a little investigating I found this.
I have a set of spare axles with me but there’s still part of the axle stuck in the the diff.
And it’s been in the high 90s to hot for me.
So all pack up and headed home in the morning.
Ran some very hard trails for full bodied rigs and had a great time.

I have a full set of spares, but with a piece of the axle still stuck in the diff I decided to throw in the towel and fix it right in the comfort of my shop.
The spider gears are most likely damaged, at a minimal the diff needs to be pulled and inspected, the housing thoroughly cleaned to make sure there's no metal in there.
I only had one day left and I would have spent it doing the work in 100* heat

You have a video of you snapping your axle?

I’m really not sure where it happened, there’s a video of me in the V notch where I got stuck you can see that the rear driver was turning and then it wasn’t.
I didn’t realize it was snapped until the next obstacle.
I believe it got twisted and compromised the day before.
Then getting bound up in the V notch finished it off.
Kenn was spotting me and Dan was riding along. None of us heard any popping or noise.

looks like the front side of Daniel at uwharrie. That ledge is about 3ft deeper now
(Stock 80 rear shafts in my rig, btw). I have never hurt them, ever. Still on the same pair since 2016. that is eight years with V8 power, manual trans, etc
@Broksi did you ever break a stock shaft before "upgrading"?

Yup!
I went back to stock shafts and continued beating the shĩt out of my rig.

I've seen a few E-locker version shafts twist at the long spline part but I can't say I've actually seen a "un-locked" shaft break myself?
I'm sure someone has but I haven't seen it happen at an event or online that I can recall

This is what I was implying in the other thread, when I said the only ever see broken axle posts I ever seem to see are re: RCVs. I think I'll scratch them off my upgrade list and see how the stockers fare, based on these posts.
+1 on that . For rears hard to beat oem . even more so after cyro treating . I broke a few sets of rear rcvs. I twisted a few stock rears but never a snap . Ran the cyro treated stock rears for a few years never had a problem . Richard you must have bound the s*** out of that Ive never seen a 300m snap like that Mine always sheered off super clean almost looked cut. In the pic.... Broke 1 rear axle, both frnts, frnt and rear locker, frnt ring and pinion . It wasn't a cheap day. PS who ever said " when in doubt throttle out"" is a fricken lair hahahah
While not a hardcore wheeler, I have done plenty of crawling and bounced the truck a bunch of times on the stock (400k mi) shafts with V8 power in the 15 years I’ve had it. I assumed RCVs were OK, but I’ve seen those Nitros blow while doing almost nothing. Lol

With all due respect Sir the RCV Ultimate 300M 80 Series rear axles did not hit the market tell around 2019
At that time they also started to offer the ultimate 300m fronts with a 30 spline outer upgrade. When I snapped there stranded fronts they gave me full current market value ( more then I paid ) towards a ultimate set I just paid the difference no tax or shipping and they were on my front porch in less the a week from sending the first E-mail 
IMO they hold up pretty well but the big thing is they fully warranty them. I already reached out to them and the only thing the asked is which side I needed the long or the short.
Those rear axles have been in there since 2020 the hole time running 39s smashing trails like Pritcheet Canyon, Fordyce, Rubicon and countless trips to Moab, Sand hollow and Johnson Valley.
The thing is that I really Like wheeling the 80 when I role up to the Soup Bowl in the soccer Mom wagon I see people snickering and people ask your going to try it in that
then when I one shot it there impressed and make a video of it called the Boss 
A few years back a procured a 40 based tube buggy one tons and 42s, was it cool, was it Bad A** yes it was.
But it just was not the same people just expected it to make all the hard lines. when it got 100* out I could not turn on the AC, Yes I like the AC when it was super dusty I could not just role up the windows.
That and I'm going to be 67 this year ( going on 50
) so currently looking for a clean old classic Cruise to hit the easier trails with.But I'm not ready to give up the 80 or all it has to offer, I still want to hit the hard trails in it. IMO it has proven itself to be a contender !
Cheers
That buggy does look awesome though. But I 100% agree with you about the dust and AC and I'm only 42. 
That was such a pretty car . A shame you couldn't get it dialed to your liking . Your a Big guy finding a used buggy that fits is hard. I got tired of climbing in and out of mine . I did red dot style side tubes which made it better .. I'm with you a/c, heat ,windows haha. Amazing how not having such basic things suck. Your 80 is very respectful I seen you drive it and pics over the years of where you have been .Id be proud of it too.. You built great machine why not take it to the next step when you buy a different rig for mild stuff? Thats what I'm doing with my white 80. Phase 1 is getting the Ls in and dialed. Phase 2 tons ,atlas, linked caged , Some body changes to suit it better for crawling and to minimize body damage. It will be just short of a buggy. I enjoy the red 80 I just built on 33 so much I don't think I'm going to sell it . Ruby is my new daily .. The white 80 is going to become a trailer queen but still street-able to drive to local trails.. The 80s ride and comfort has soiled me . As much as I love the 4x and 6x I have no desire to spent the day on leafs.With all due respect Sir the RCV Ultimate 300M 80 Series rear axles did not hit the market tell around 2019

You can upgrade to 105-series rear shafts, as well as rear hubs which have larger dowels and studs. You would have to swap in a 105 diff though or swap out the spider gears. You would also have to go to five lug wheels. It is all pretty much bolt on though.
I know RCV makes shafts for the 105/79-series too.
I think that is about as strong as you can get with Land Cruiser axles.
One of my two "crawlers" I am just going to end up dropping big $$$ on a set of Spidertrax front & rear. The other is staying with Toyota axles.

Again Folks I’m super happy with the way my setup is now
If you’re going to wheel the way I do you have to expect some breakage.
IMO its been minimal
