14 Bolt axles in Land Cruisers

[CruisinFJ60]

looks pimp, cant wait to get one under my truggy, but I also gotta see if I popped both longs first...

Nice work man. A friend of mine actually got and old Chevy 1-ton wrecker to lift the front end completely off the ground while trying to get a vehicle out of the mud. All that weight and torque on the 14-bolt and it didn't flinch. I doubt there is anything stronger unless you spend $5k or more. I love that type of American engineering.

I know this thread is an old one BUT it is a great read. How about an update??????????;p.........
Has anybody else tried this mod on a 14 bolt.
How about a differant mod to make the 14 bolt work.
WHAT SAY YOU??

 

[PPFJ60]

I just bought a second 14 bolt. Not sure what i'll do with it but it will end up under something. I paid $60 for the first one and $50 for this one.

By the time I was back on the road with the 1st one I spent $1500.00.

Add me to the 14bolt cruiser club. Swapped the tubes and made my own drive shaft. Aside from a little brake dragging it's been great.

 

[CruisinFJ60]

I'm also in now. Got one under the truggy and have another that will be going under Fiona as well.

 

[PPFJ60]

I measured the axle clearance tonight. The tires are worn out 37" that measure close to 35".

Front from the ground to the bottom of the diff = 11 1/8"
Rear from the ground to the bottom of the diff = 11 1/16"

 

[LCOwner]

Did you reinstall the traction on the rear?

 

[PPFJ60]

I put my anti-wrap bar back on when I put the 14 bolt back in.

 

[LCOwner]

Got any pics?

 

[PPFJ60]

Here is a crappy picture I took this morning. I'll try to take a better picture later today.

 

[mookie]

those of you who have done the 6-lug conversion on 14 bolt hubs, what kind of brakes did you put on? anyone have part numbers for the rotors, calipers and where and what type of brackets you got? i have chevy monte carlo disk brakes on the rear of my 60 axle now, could those be re-used with the proper brackets?

 

[chicago]

I am also curious about the 6 lug conversion on these as well!!
So in all of my reading thus far, one COULD HAVE just cut 6 in off of the DS to make it line up w/ the t case, correct? Then you could use two short side shafts? Id almost be half tempted to go the route you did and MATCH the FJ60 width, but did you have to have custom axles built?
I wish you had gotten some pics of HOW you lined up the tubes for re welding!! Sounded as if you ran a tube that fit the ID of the 14 bolt housing and used some angle iron clamped to the housing as well?
Not planning this to happen quickly, but Im really considering picking one of these up and building it over time.
Oh yeah, did you have the ring gear machined for the shave kit?
Did you do the gear set up? If so, how was that?

 

[GLTHFJ60]

I'm in the process of building my 14b up to put into my 60 this weekend. It's nearly complete, so I'll give you some info. I'm not modifying my housing ( centered rear transfer case ) nor am I running 6 lug hubs, but I have gone through the rest of it.

Oh yeah, did you have the ring gear machined for the shave kit?
Did you do the gear set up? If so, how was that?

1. The ballistic fab shave kit requires that you machine the ring gear. Their kit comes with a rear cover and plate for the bottom of the center section, which you cut off when doing the shave. More info here:

http://www.ballisticfabrication.com/14-Bolt-Shave-Kit_p_1728.html

2. Setting up the differential seems to be super easy. I did mine a couple of nights to go. Since the pinion drops out of the housing, you simply assemble it into the pinion carrier ( is that the right term? ), set the pinion bearing pre load ( PBPL ), then put it up into the housing with your appropriate shim between the pinion carrier and center section. Carrier Bearing Pre-Load ( CBPL ) and backlash are set with carrier bearing adjusters that are locked in place with a fork, one for each side. The full instructions for setting PBPL, CBPL, backlash and then checking your pattern are located here ( linked from the 14 bolt bible on pirate ):

Finally, brakes. You can buy disk brake conversion kits for drum brake axles from Ruffstuff and bolt up disk brakes. However, what appears to be a better solution is to run the later model 14 bolt ( now called the Chevy / GM AAM 10.5 ) disk brake / e-brake setup. This leverages a drum-in-hat e-brake design that provides a good, reliable e-brake while providing disk brakes with a floating rotor. Super slick design. AAM 10.5 axles are beginning to get cheaper and cheaper. I got mine for $250, with calipers, rotors and 4.10 gears w/gov-lock.

One thing I haven't figured out yet is the brake line. The brake line on the T on this newer 14b seems to be larger than 3/8", so I'll figure out how to adapt that to M10 in the next couple of days.

Here's a quoted post from Pirate4x4.com that outlines the newer 1 ton axles:

all the above is true. these axles are not the same
both have 10.5 ring gears but there different. both use 30 spine shafts
as well as the 11.5. the dodge one does not have the drop out pinion with the 3rd support bearing.

dodge 10.5 specs
1 of 3 widly used axles disigned by aam off of the corperate 14 bolt design
the second is the 11.5 and the third is the front 9.25.
the 9.25 was based off the semi float 9.5 14 bolt

all axles share designs and some parts but are not the same in any way. just like dana 60/70.

i have worked on all 3
yes the majority of the carrier parts are interchangable from the corperate 14 bolt and the aam.minus the pinion bearing.
my rear is a aam out of a 05 and has a posi currently from a late 80s with the stock 4.10 gears from the 80s.
the brake mounting plate on the axle is different due the disc brakes used on the newer version. obviously spring perches, shock mounts ext are different
wheel studs are metric 14 mmX1.5 threads on the new ones but still have the 8x 6.5 pattern
diff covers are the same but the new aams have metric bolts. my diff gaurd bolted right up with the correct hardware

yea sooo thats all i got for you off my stored info

edit: 2011 chevy changed lug pattern to 8 on 180. i havent seen a 10.5 in any truck locally all of them come with a 11.5 gas or diesel here. i dont know if the discontinued the corperate design 14 bolt or not maybe someone else knows

FUGGIN AWESOME INFO BROTHER!!!! Im contemplating getting an atlas...If that happens, a 14 bolt will be IN!!! K

 

[GLTHFJ60]

Brakes are figured out. I got a new axle-to-frame line shown here. Napa part 381272. This line has a 7/16" fitting on the end, not a 3/8" fitting.. The Napa store I went to carries all kinds of hydraulic adapters and fittings, so I found a little sleeve that goes from 7/16 to 3/8". All I had to do was cut the M10x1.0 fitting off of my pre-existing 3/16" brake line, put a 3/8" fitting on with a double-flare and I was good to go. Piece of cake!!

Add me to the 14 bolt club.

 

[uglyoinker]

I wanna get in the club!!! Where's the door with the bouncer?


I recently grabbed a set of Chevy 63's and a factory disc 14 and the bucket seats and console/seat out of a wrecked 05 2500hd. I'm planning this for the rear of my 55.

 

[mookie]

Add me to the 14 bolt club.

Looks awesome under there!

My 14B project

I've been working on a narrowed C&C axle for my 40. I still have to mill the shave plate and drill it for cover bolt holes, but I was able to get the diff assembly in yesterday after not touching this for months. It came with the 1/2" thick tubes. After I weld the tubes back together, I'll figure out the custom shafts.

The 14B is next to the fj62 rear my son bought for his 40. They're the same wms.

yeah it does, i saw this the other week while in town and it looks like it belong under the 60s. and im pumped to soon be part of this prestigious 14bolt club. membership dues are expensive though, but they're perpetual memberships i hear....
