C-Clips (c-washers really) in the rear diff on semi-float? I don't see a true BFH on the ground either.

Bigger hammer.

No c-clips in semi-floats. Just unbolt the hub/shaft assy and it should pull out (done it before).

Not sure how anyone expects me to add heat to the internals of the axle housing. I guess i could light a fire inside it

I actually don’t own a BFH any bigger than the one pictured. Never needed it until now i suppose

bigger chain....

Got it. Now the issue is that I can't get it back in...the bearing is slightly dislodged. I'll try to press the bearing on and see if that gets the shaft in further

Might be time to throw in the towel and buy another shaft altogether...

Semi-float is some bullish*t. So are OEM rear lockers when you're really using them

The shaft I broke back in November broke at the same place. Seems to be the weak spot on the 100 semi floaters (at least the locked versions)

What finally got the shaft to dislodge at the hub?

What finally got the shaft to dislodge at the hub?

Yesterday I was attempting to pull the shaft out of the hub assembly. Today I pulled the entire assembly with relative ease

Now I can’t get it all back in because I managed to pull the shaft off the hub slightly yesterday…gotta press it back on then i can re-assemble

Here's the old 80 thread on the subject of OE rear lockers being less than ideal- Twisted rear axle shaft - https://forum.ih8mud.com/threads/twisted-rear-axle-shaft.239583/post-4572152

Post in thread 'Short side axleshaft mod?'

Jun 12, 2017

Here's a clear pic of all the action per 3 I bandit specs..still a witness mark on the 1.175 segment, and I haven't tested function yet...another pic from a different thread for this mod looked different and appeared to machine down to the aforementioned witness mark.. magic happens when we dream together so just sharing

• dirtyboots

Here are some relevant threads I've stumbled across in regards to this.
I'll be attempting to "machine down" my splines on this shaft with a grinder/flap disk next week. I plan to replace the shaft eventually and will have that one milled on a lathe.

here is a pick of a production shaft after turning.

You'll see that the roots of the splines are still visible. The shaft has been turned enough to allow the collar to rotate on the shaft in that section but now the collar will be held in place better to aid in installing.

Post in thread 'Twisted rear axle shaft'

Jul 2, 2009

no problems with anyone... at the moment

here is the drawing that I've come up with. If you want to use it it's all on you.

Right now I wish I had more data that just two twisted shafts but it is what it is.

My bad shaft gets to poly performance tomorrow so I'll call and talk with them on Monday.

My first inclination is to only remove the splines outside of the collar in hopes that the twisting stays localized there and eventually breaks there as well.

I don't know right now and need to chew on this a little more in hoping that I make the right call.

I included a PDF...

• landtank

Apparently the drawing in this post from @landtank is inaccurate. I can't assume that the 100 shaft is identical to the 80 since they are 32 spline vs 30 spline.

I doubt many 100 owners have had this issue yet and if they have I need to meet them.

Is it possible to run standard LX shafts without the longer splines with something like an airlocker?

 

[hoser]

^^^ yes

 

[cruiserpatch]

^^^ yes

Yes lots of 80 guys have had this discussion. Christo chimed in a fair amount back in the 2010s recommending something like an ARB to prevent this issue

I’ll be buying a spare shaft soon. Not sure what I’ll do long-term. It will honestly depend on future problems which will hopefully be minimal now that I’m more cognizant of this “feature”

Just found this super helpful chart for Dyna Bead calculations/recommendations based on tire size/ratio etc:

Aggressive Tire Chart

I've got some wobbles on the highway above 55mph- time to get them sorted

Stupid vandal- I would call him a thief but he didn’t take anything

Just left me with a mess to clean up and another reason to move back in with my parents (sorry Jimmy and Tricia- you thought you had gotten rid of me)

Same happened to me in Memphis a couple years ago. They didn't know my German Shep was sleeping in the back...

So frustrating when that happens…
