considering the breakage this weekend....

[DSRTRDR]

I think I want spare axle shafts for the rear

anybody have some for sale for a 40 rear drum brake semi-floater axle ?

according to the CruiserFAQ: "68 and later shafts have 30 fine splines"

according to SOR catalog, there was possibly a breakover at 9/73; so I would need earlier than that

Howdy! Not sure, but that may have been when they changed the axle bearing. Early ones had an inside race that had to press fit onto the journal of the axle rod. Newer ones use the axle rod as the journal. I don't really like the newer ones so much. Even though it allows the rod to be just a bit larger O.D., I have had two of them wear down from use. I don't like it when it looses 0.020" from the bearing surfaces. John

Claudia,
It looks like we will be tearing one down this weekend for pinion parts for Justweldit, I already have spare rear shafts ready to go, so if you would like I will hold the shafts apart for you (depending on the vintage of the axle), as the only things I needed from the rear was axle studs....not too high of a priority now though with dedicated needs out there.

You can have anything you would like for the same price as that brake booster and resouvior you picked up from me at Truckwerks last year.

 

[DSRTRDR]

what year axle are you tearing down ? sounds from the other thread it could be a '76 ?

and what year would the shafts you already have be from ?

yes, if you could hold until the Christmas vacation that would be excellent

yes, the breakover appears to call for a different axle seal/rebuild kit - would the axle shafts themselves be interchangeable ?

If not, I would need the early version - no idea how to tell them apart

Did you try Tim?

I have been searching around and I consistently come up with reports that all Post 68 rear alxles are 30 Spline and are the same...

They are all the same except for really early (read 1960's) cruisers.

What are you planning on doing with the vehicle.

Wheel, around town, both, diveability?
What lift, tires, engine do you have or plan to have?
Front, rear?
Budget?

Give us something to go off of besides a 78. That basically tells me nothing.

yeah, that is my impression, too - prolly just the bearings are different.

I'll search around some more and ask some experts

but if you would be willing to hold the shafts that would be great BTW, got C-clip ?

Thanks in advance, Claudia

 

[FJ40LVR]

Yes,
I got a baggie of em somewhere.....

 

[DSRTRDR]

if I interpret the picture in the other thread correctly, the coarse spline shafts should be from before '68

I am pretty positive I will need the 30-spline

i agree that the thirty spline is what you need ,did you want to carry these with you every trip? how many of you guys carry spare parts on a local run??????

 

[DSRTRDR]

you don't wanna know what I all carry for spares some 5 boxes, a sixth in planning, and some stuff in the glove compartment suffice it to say, I have a hard time remembering where I put the stuff, so I typed up a list - it is 5 pages single-spaced

I don't think the axle shafts would be useful in the garage with the type of breakage we had

 

[justweldit]

i could see taking a bunch of stuff to moab or even on a trip down south but when i take my kids in my 40 theirs not alot of room! you guys have been wheeling a long time how often does some one break a birf or an axel

Anyone else along with an older 40 should feel lucky with you in the bunch

So far I've got my junk trained to break in the driveway

 

[Tools R Us]

I don't see the logic for carrying spare axles? In years of wheeling with/in FJ's I have seen ONE break on a 37" tire rig. If Claudia had broken one, the scenario would have been about the same. Run to my house, pull an axle out of the "40, go back and install, would have been home in bed by midnight and on the trail in the morning.

I would rate the chances of axle breakage on a 33x10" tire FJ less than the chance of cracking a transfer, are you carrying one of those, or a spare trans, motor? It's not a heep!

 

[ChaseTruck]

I don't see the logic for carrying spare axles? ...

It's for balance. The FJ40 is so nose-heavy that the only way to correct that is to put more heavy stuff in the rear.

Wait, didn't you just tell me the other day on the way out to AJ about the benefits of spare rear axle shafts because the rear axle always gets you home? Or was that just referring to "...if you feel like carrying spare axles in the first place, carry the rear, not the front..."

as for the storage space, I use the room under and behind my rear bench

and yes, I have never broken a birf or any other part that would have stranded me on the trail for that matter, knock on cruiser



as far as what has broken to date (4 years or so):

luckily, I discovered the frame crack before going on what would have been rocker Panel Pass having run at 75 mph the day before returning from Tuscon after running Chiva

and the steering stabilizer bracket broke when I was hearing a snap sound before a lunch brake in Moab but wasn't really discovered as such until we had returned to PHX two days later

the punched tire in Payette happened just before lunch on a brand new tire

the mangled front bumper occurred late in the afternoon

and I was able to diagnose a blown fuse for the ARB compressor and replace it by myself before entering Hell's Revenge for the first time in my life

also found a fuse blown shortly after I had got the cruiser - had to short it to get the cruiser off the storage lot - ran that short until after having run my first Moab at Easter Jeep Safari ;p


really, other than that, the cruiser just runs

I distinctly remember that it was relayed (at some ungodly hour IIRC ) to me that expert sources thought that, considering the breakage seen today, maybe it would bee good advice I should be looking into...... (or some such verbiage to the same effect ....;p)


hence this thread

...Sorry I couldn't be of help on this, looks like it's time for a quick drive down to Marana...he's got em.

I guess I didn't make my point very well. It was; I don't see the logic in carrying axles or birfs, having them available yes, carrying them, no. If your going to schlep them, rear would be more important on a semi-float axle rig. But they are well proven, the chance of one failing is very small, so to me not worth the weight penalty.

If it were a solo touring rig I could see it, but we usually travel in packs, so have more options. The way we roll and trails we run, I don't see us even changing a birf on the trail. It would be more like, take enough parts off to make the rig roll, take the bypass/strap to get the rig back to town, then change it.

Maybe for the long, remote Utah runs? But even then Rising Sun has axles in their spares trailer, so it would be a run to scum rock to barter one from them? To a certain extent you need to carry what makes you comfortable, but I don't see carrying low risk/heavy/large items. It just increases rig weight, making the chance of breakage higher and you can't carry everything that may break. IMHO it's better to carry a couple of sleeping bags, some energy bars/MRE's, water, etc to make the wait for parts more comfortable and have a lighter, better wheeling, less chance of breaking rig?
