Later 60s era FSJ axle/brake question

[FinoCJ]

What brakes were used on mid to later 60s era FSJ axles - These would have been D27 and D44 axles. According to Jim Allen's book, these would have come with 11x2 drums, but are they Bendix style self adjusters, or the Lockheed manual adjusting type found on the wagons and trucks of the 50s?
Also, the rear D44s on these look to have had one-piece flanged axle shafts? Would they have been 30spline units that would accept modern selectable lockers?

I thought those years were all Bendix brakes. When I was looking to ditch my 9” and go to 11’s my junkyard search encompassed those years.

Doesn’t mean I’m right or that all FSJs had them..

Waiting for someone to prove me wrong.

Well, I went a grabbed some axles that I thought were out of a 60s Kaiser era FSJ.....mostly the price was right and I wanted some of the parts. But then some interesting details popped up. The width of the axles is correct for 60s FSJ (and the same as my 50s wagon), and they could be considered as swap potential for the 58.
1) The rear D44 has flanged axles, which I assume are 30 spline inners - in addition to being stronger than the tapered axles, there would be selectable locker options that could be used.

2) I assumed the front was a D27 (which was basically take off parts in my mind), but turns out its a closed knuckle D30.....well I think that is what it is. Has 30 cast into the pumpkin flange, and has 27 spline outers. I would think this D30 would be a nice upgrade over the OEM D25, both in terms some minor overall strength gain, and again, options for selectable lockers is big to me living and using the rig on winter roads. Obviously, as a closed knuckle so its probably not the latest and beefiest 30. Most want to upgrade to D44s (scout or NT wagoneer), but this seems like a good step in that direction with much less additional modification.

I think both these axles are worth keeping around in the corner...It looks to me like they could work really well in a wagon. I do have a Scout D30 open knuckle as well, but thinking that is kind of a dead end as i don't want to deal with the leaf spring/spring pad issues, nor the caster issues, so this seems way better......they are geared 3.31 (tagged on diff, not confirmed with tooth count yet), which is actually a decent gearing for the sbc/465 combo in the 58 (and leave out the OD....going D20 would be nice combination)

Bendix brakes all around on the axles I picked up....someone else will have to prove you wrong.

Just read this after replying on the full floater thread.

These axles look great for the wagon. Check out the bearings and seals and run it. I chatted briefly with Jeff P. (Classicjeeptops) About the full floater conversion and he speaks highly of the stock flanged D44. In my opinion the only down side It is a pain to press wheel bearings on and off of them.

The Wagoneer and lightest J-trucks with the 44 rear axles had 11" Bendix brakes.
Mid-GVWR J-trucks used a 60-2 rear axle and 12"x2" brakes (unobtainium today).
The '72 and '73 Wagoneer came a with Dana 30 front axle, with closed knuckles.
'70 or '71 may be a 30 also - not certain - and earlier came with the 27.
A flanged rear axle confirms '72-ish origin.
Could have come with the TracLock - popular option.
AFAIK there's no hard-and-fast date for the flanged rear axle changeover, just 1970ish.

Centered 5-lug rear flanged 44 is a good find.
The 30 has the obvious drawback of closed knuckles; worked well enough in these Wagoneers.

The '72 and '73 Wagoneer came a with Dana 30 front axle, with closed knuckles.

Did the axle width stay the same all the way through 73? I guess in 74 is when the front D44 came around and a slightly wider track - and of course there was the wide track stuff in the J-series and chief models.

Yes, that's right.
'74 has the front 44 with open knuckles, optional disk brakes, 6-lugs, and Delco drum brakes.
