I'm trying to figure out what to do with my Non USA front axle. It is a 1980 model so I have the larger knuckles but it is a drum brake axle. I talked with Poser a few months back and purchased a rear disc brake kit (still need to get the calipers). I planned on keeping my front axle and using a disc brake kit. Problem is they won't work with my weird setup as I have the larger knuckle and all the kits are for the smaller knuckle. (I'm also wanting to keep my 3.73 gears and stock width).

Poser recommended a FJ60/62 axle and swap the birfield over to my axle shafts, take the spindle, knuckles, rotor/calipers and hubs. Only real difficult part would be centering the knuckle. I purchased a FJ62 axle but have been having a hard time picking it up (about 4 hours from home). I'm thinking building it is cheaper and just as easy as buying 6 shooter knuckles. I'm all about saving money on this overly expensive project but want to do it all right the first time.

I have been looking at hi-steer kits and upgrading parts. I will be going to a power steering setup (was planning on a FJ60 setup, but no decision made yet). Going with a 4" lift to clear the Mercedes diesel swap so I figured what they hey.

So tell me if my plan is off or I'm missing something.

I'm taking all as noted above from the FJ62 axle and then using Lukes kit to install the 6 stud arms and hi-steer.

Is there a better cheaper way to do this and am I missing anything. I know the hi-steer is not necessary, but for me the disc brakes and power steering are. This will never be a hard core off-roader (very mild trails and 33" tires) but I figure this is the best way to get disc on the front of the truck relatively cheap and take care of all of the necessary changes for the power steering setup all while conveniently getting hi-steer out of it.
 
I'm doing the disk conversion on my 78 non us. Mine does not have the larger knuckles tho.
Do you know if you have the long axle shaft or short? You can tell by looking at the length of the locking hub. If you want, you can keep the same birf/shaft and locking hub. That might save some $.
Otherwise, the 60 axle parts sounds like the right plan. Also, there's no way I would do all of this and then put in an old rotor and caliper. That's the FIRST thing I would upgrade.
 
You have to center the 6 shooter knuckles also. With arp studs you don't really need 6 studs. You are also going to need all the brake parts spindle hub backing plate and the that can add up quick

Ain't that the truth. My mini truck parts cost maybe $175 and I can get most of that back by selling the stuff I don't need. But the knuckle kit (I did wheel bearings too as long as I was doing everything else), rotors, calipers, pads, new extended soft lines, wheel studs, grease, tools (TRE tool, spring clip tool, shaft alignment tool, ...) added up quickly. It's very easy to get into the mode of "as long as I've got it torn apart...". No regrets tho.

Spindles are the same...

:meh:
 
So Poster, did I remember and list everything I need above correctly?

I think the FJ62 axle has everything I need. I know I can get new calipers with my cores for 32 bucks (doing it on my ACTUAL FJ62 tomorrow) so that is not a big deal.




Jason-


If you intend to run the six stud knuckles, the only components you will be using from the FJ-62 front axle will be the caliper mounting hardware, the stone shields, and the wheel bearing hub/rotor assemblies.

The outer axles, the birfields, in your current non-USA drum brake front axle are the same as those found in the FJ-62, so you will not need to swap them. Also, the lockouts from your current front axle will work with the wheel bearing hub/rotor assemblies, so, if you need to find a new home for the lockouts and mounting hardware from the 62 axle you will be parting out, I know of a good home for them. :)
 
you say non us axle, aussie?? if so the 60swivel hubs should bolt straight on to your 40 housing. just need the 60 tierod ends to suit (bigger taper)



The current axle is a 1980 non-USA drum brake unit. It has the larger pattern 55mm x 30mm with 12mm studs, vs, the 12/78 and earlier 46mm x 30mm with 11mm studs.

This means that there is no need to use the FJ-62 steering arms as the current non-USA drum brake arms are compatible with the 60 series disc brake knuckles.

I do actually want to use the FJ62 knuckles and lockouts as the AVM lockouts on my current truck are in rough shape and one of the knuckles studs is stripped out within the knuckle.

Shouldn't be a problem right? I just have to bring over the outer birfield right? Or I wonder if the splines on my FJ40 is the same.
