She back together with all the while your in there stuff. Took her out for a test drive everything works as it should, no weird noises.
Got her in a big dirt parking lot, locker lock all 4 wheels pull 😍
Then I re-spooled the winch, it really got a workout getting me off the trail, multiple full length of the rope pulls.
It ended up all kinked and pinched, literally had to power the line out off the spooled. It's all reset now ready for it's next duty !!
 
Here's the two snap rings, OEM on top RCV 300M one the bottom.
As you can see the OEM one is made out a wire like metal. The RCV one is flat plate like more like the one at the drive flange.

The RCV 300m snap ring is also bigger.

Compared to OEM

The standard RCV 24 spline axles are the same size as OEM axles and use the same OEM snap rings
The RCV 300M ultimate 30 spline axles are 2MM larger and utilize the larger snap rings, Although I'm told the the OEM rings will work. 🤔
 
I like the square cut better its going to hold alot better.. could be why you have such a hard time getting your off

Makes perfect sense !!

I just had a thought I dont think that is the correct clip from rcv.. The clip that stops the birf is square cut the one that goes in the birf is round dont put that together yet you might not be able to take it apart. I have both clips in that garage ill take a picture

It’s back together, but I used the one that the axle came with. So if I got it apart once it will come apart again 😉
Of course the axle was covered with grease, and I did not remove the snap ring from the axle before installing it into the Birfild.
So I don’t know if it was round or square.
RCV didn’t have the snap rings for the drive flange just the ones for the inner axle/ birfild.
If look at post 1,245 first picture you can see that they both have a very big mouth/opening in the ring.
The spare snap rings I got for the drive flange’s are square cut but the mouth/opening is much smaller maybe 1/4 of the other ring and are a little smaller size.
I think that so you can use snap ring pliers on them, and the bigger opening is to help facilitate removing them from the Burfield.
I did see that the inside the Birfild where the axle slides into the splines it had a chamfered/beveled edge.
This help the axle slip in.
Most likely the cage has the same thing on the other side to facilitate removal.

I will probably call RCV and ask them about it. 🤷‍♂️

I used oem style rings in my 30/30/30 axle set bc the square cross section of the others makes separating birf from inner shaft a monumental bastard of a pounding job.

Yep been there done that.
At the same time I would not want them to separate unexpectedly

Not anywhere for the parts to go. There's no real pressure on that snap ring when it's assembled.

RCV felt that there was a reason to make a beefier snap ring. 🤷‍♂️
I’m no engineer but I’m sure RCV has some good ones on there payroll.
It’s my understanding that the inter axial can walk too far into the third member, and that’s what that snap ring is for.
someone with more knowledge than I will probably chime in😉

I have to agree with @Feldrian that there not much pressure there.
But that doesn’t answer the question why RCV made a beefer snap ring.

You and @Feldrian are correct in that there is not much lateral pressure on the circlip. The two snap rings simply prevent the inner axle from walking side to side. The flat snap ring prevents the axle moving toward the birfield and bottoming out into the bell. The wire circlip prevents the axle from shifting toward the diff. I suspect Toyota used the wire circlip to make it easier to remove. RCV may feel that a heavier, flat clip makes a stronger product. Or, maybe a flat machined clip is more readily available and therefore cheaper than custom forming a wire. Who knows.
You've got your axles together. Run em.

And since I'm already hijacking your thread @Broski, anyone remember the Martack? Marlin Crawler began putting a small tack weld on the differential splines of the axle and then omitting the wire circlip. This made swapping a birfield easier if you grenaded one on the trail. I still have my FJ40 axes set up this way.

Not a high jack
And the Martack is exactly where my thinking was coming from about the axle walking to far into the third.
The 300m 30 spline axles are 2 mm thicker at the birfild, so while the OEM ring may work, my guess is just barely.
Your explanation on the bigger flat snap ring make a lot of sense.
I payed a lot of money for the RCVs and fore whatever reason that they decided to use a bigger ring I’m running them.
