Broke another Axle... (Video)

[Apollo]

Alright alright. I had a little nappy nap and I feel better now. Moving on.

So I had them change my diff fluid in the shop yesterday in case some water got in.... good thing I did.

and I checked for binding at full droop, and there was none. @orion .... no I did not turn the wheels side to side... and I should of. I might try it during my lunch today. It is a very steep angle...

Perfect video title. The CV angles says it all, they are at an extreme angle and that is why you are breaking axles, binding or no binding. At least you have confirmation of the root problem, now the solution…..

That does look pretty extreme of an angle. I wonder if maybe under pressure they react differently. Or it could just be like you said over time they wear out faster. Either way it is definitely the angle causing them to wear or break.

Now that is a You Tube title that I like!!!! Ha ha ha ha...

Got to admit that the CV angle is pretty extreme but yet it is close to parallel to the lower A arm.

I would definitely be looking at the RCVs. Even that is not going to be any guarantee. Yep, the old story of break a part, upgrade, break the next thing in line... It is an age old story.

Sorry Dude!

Oh... and as others have said.... Do not pay any attention to the title police. If they are not complaining about the title they will find something else to complain about.... Some people just have an irritating innate need to correct everyone else because the world is not what they think it should be... and since they think it, it must be apparent to everyone...

Your title was perfectly appropriate.

Just as an aside to this discussion...

From everything I've read, The RCV axles (And the Spicer Extreme) don't provide any more protection from bind or extra operating angle over the stock axles. They're just more durable and can take a bit more abuse, But they are still gonna break under conditions that would break the stock axles, it'll just take a little longer.

I run RCV shafts in my jeeps, where there is a perceptible benefit in the smoothness of operation and bind elimination experienced with U-Joint shafts, But a cost/benefit analysis in the Bronco doesn't show much value to me.

I'd fix the angle/droop problems, and rock on with stock shafts if it were me.

Well the path forward seems clear now....... 40 inch Tires

actually Spicer does claim the ultimate 32 spline CVs can handle.more angle than OEM...

40s are great...you don't need this much lift to run 37s or 40s...I run 40s with only 1.5" lift.
If it's ground clearance your after, then save up.for portals...you'll be forever chasing issues with that sketchy double lifted setup yer runnin... by the way since you have this kit I'm curious if the installer actually cuts the rear cross member out and drops the diff down a full four or five inches like it should be or if they only use that one inch diff drop that I received from Rough Country? Because that's certainly not nearly enough to do what you're doing. I've run those RC knuckles b4 and their kit does not drop the diff enough for any long-term use...

Someone showed some pics of the OEM CVs and I think the for performance ones? Maybe snacktime? Can’t remember. Anyway point is the cup diameters were slightly different, plunge in/out was likely different. Minor differences in geometry will most definitely affect allowable angles and design tolerances . It is hard to imagine that the spicer and RCV CVs will behave identical to OEM.

Hmmm, I checked the Spicer website before I posted, and couldn't find that anywhere. I didn't see a separate page for the 32 spline though, and I didn't see any mention of improved angles on the Ultimate D44 Advantek FDU the 32 spline go with either. So maybe Spicer made that claim somewhere else? If I can confirm that, I'm going to be looking harder at getting those...

Yea, I wonder if I'd eventually Grenade RCV's at the angles I currently have.

So here are some real solutions I'm considering.

1- Install Vertex 5 inch coil overs and see where my droop is at. They are adjustable so I could limit it a bit that way.

2- Get these limiting straps from Bison Offroad https://bisonoffroad.com/product/ford-bronco-limiting-strap-kit-4wd-2021-2022_2023_2024/

3- And I don't like this option... but just get 3.5 inch Vertex coil overs to get better angles .....

Thoughts? And of course, RCV axles will be in plan at some point for sure.

I'd say do the 3.5 and do the ranger bolt body lift.

Ranger Bolt body lift? never heard of that? Please enlighten me?

People have bought pucks and used the ranger bolts that are longer to end up with (if memory serves me correctly) 2" of body lift. I found this out after I'd paid the money for the Bronco Buster 3" so I went that way. You can search for the ranger body bolts and find it on here. Also if you look at my build page you can find anything that binds at 3".

I like the limiting strap option but know nothing about how that kit would work with your set up…I would think they would need to longer with diff drop…

Would be easy enough to add a small spacer or make an extension with some thick flat bar. If I needed to. Could be interesting to test and play around with.
