Axle shaft question

Didn’t break them off, the ujoint went out and bent the “ears” where the ujoint connects them. The shaft I bought from rock auto is 4340 chromoly as well. I sure there may be some way I could bend the ears back but I’d rather not break my press or anything trying to.

It's the other way around. The ears deformed and took out the u joint.

Depending on the clips a bad joint can rotate the cap and toss the clip.when that happens the cap walks out and broken stuff ensues.

This is not the normal way this happens. Were you there to see this extremely rare occurrence?
 
As much as I’d love to go with Revolution stuff, its a bit too pricy for me, for now. Plus I do believe a bit overkill for 33”

Im on33's and went with the revolution axles and it would be a good replacement for stock. Its not overkill its just peace of mind that it can take the abuse
 
I was thinking this may be the case from the get go because my rear Dana 44 got the same treatment but with 35 spline and arb RD109 and modified ends to accept SET20 bearings…

I keep reading that and I'm trying to figure out what you are going to get for a replacement should the need ever arise. Who does that?

No idea… I didn’t think it was a normal thing either but 🤷‍♂️. It works great. Hope the need for replacement doesn’t arise…

My brothers rear tj 44 has a dutchmen kit like that.

Not unless someone welded on new housing ends which is the confusing part. No TJ needs Set 20 bearings on a Dana 44. They run Set 10 Dana 44 shafts in the Currie built G2 housings on larger than anything a 44 can handle with no issues.

Yep,dutchmen 35 spline shafts with new ends welded on. I found it on pirate close to 20 years ago for pretty cheap with an arb and 4.88s. He's never had to work on it

That’s exactly what mine is, you can see where the ends were chopped and new ends were welded on. Unsure why, maybe to run the rear wilwood disc brakes I have? IDK. Not a lot of sense to what was done but its strong. Also my rear is SOLID 25 spline

I've been wrenching and wheeling for 25 years. I've seen caps walk before that didn't have full circle clips.

Its kinda chicken or the egg.change joints on rusty shafts where the new cap winds up loose and you better have full circle clips or some tack welds. Beat on shafts and they will loosen up so the cap will spin. Better replace them or use full circle clips or tacks.dried up seized joints can definitely spin caps out.Was it the shafts? Was it the clips that pop out when a cap slowly rotates?

Not everyone buys brand new chromoly when they can get a few more years out of stock stuff.

Whoops… meant to type 35 spline, 25 would def be downgrade lol

Oh no, I’m in trouble. I’m putting about 50,000 pound feet of torque to my rear axle shafts - and I’m only running a 30 spline…

Hey, like I said… the prior owner went a bit overboard. Not that I hate it cuz I’d rather have overbuilt than under.

Overbuilt isn't always overbuilt though. The issue with 35 spline shafts in a 44 is they have very high torsional rigidity and transfer much high amounts of shock load upstream to more delicate components. Works with larger tires than a 44 should have, not so much with any tire size that should be on a 44.

Like a driveshaft u-joint? Or are you saying like the trans/TC? Could you give me a bit more explanation why it might actually be a bad thing?

I think what it means is having a very strong shaft that will no longer have some torsional give it will put that peak load on another component. Torsional flex is not always a negative thing.

Makes sense. Well as much as I’d like I don’t get much chance to wheel it hard anyways so not to worried about it
