Notched 60 front axles

[Domek]

Great timing to resurrect this thread. Am collecting parts to build up a shortened 14 bolt for the rear - and wasn't really looking forward to outboarding the front to put in a 60 housing. Mace was trying to describe the sleeve option - but wasn't until I read this thread that it made sense!

Excellent idea.

Well I am ahead of you sir!

The 14 bolt is already under the 40 and I got the 40 front axel with some 2inch 8 lug conversion/adapters to match the rear wheel pattern. The adapters help but still I got a wide rear axel and a short front.

I was thinking of buying a complete Fj60 axel and slided in or do the the sleeve spacer if it still sells.

...but even if we do the sleeve thing we still have to buy the inner axels since the long side of the 40 is smaller than the fj60.

It's matter of crunching some #'s and see which is our best option and find out who sellls this sleeve spacer.

sleeve is sold by lcwizard. he's posted to this thread several times.

Also, Uncle Ben had done a Similar Mod with his 40, Maybe PM him and see what he did different than this Spacer..

Please excuse my ignorance as well...
Im gonna need some clarification on this one too.
Lets see if I have this right?
So, the 60 housing with the outboarded springs will yeld tire rub on the springs at full turn? is this correct?
So the options to prevent this are to leave the springs in the stock location and notch the housing on the PS side, extend with the spacers the short side of the 60 housing, or BOTH sides of the 40 housing in lieu of out boarding?
How do the longs work with each axel? If I were to do the mod to the 40 housing, I would then only need the 30 spline super set for the 60's to go into them?
I have a 40 axel right now, but Im planning on getting and running a 60 series axle up front and out boarding the springs. however, the tire rub affect does NOT sound appealing to me for my 37's im planning.

Great thread, just trying to follow what is happening. Im MAYBE one step up from a chimp.

Sort of.

If you outboard the springs for a 60 axle in a 40, your tires may rub (depending on your stops)

If you take a 60 axle and add the "extension" to the short side, you will not have to outboard your springs. And it will be less likely to rub. But will be ~ 62" wide in the front.

If you do it with a 40 front axle, you will be approximately the same width as a 60 axle. (I actually have to do the number crunching to see how close it will be)

Notching the 60 axle is only if you do not widen the housing and do not outboard the springs.

I am not a fan of notching the housing. I have not sen it done well ever..

Why can't I find the tech page that list the short and long side lengths for all the land cruiser series truck and the mini truck?

Maybe, it depends on the final setup. I outboarded my springs 1.25" My tires barely rub on the springs, sometimes, (full turn and full compression or droop i'm not sure), I have never noticed and the only reason I know is because the springs are polished in those areas. I am sans steering stops. This is with 40s, 3" BS wheels and 1.5" spacers. Before I had 37s and no spacers on the same wheels, I remember the situation being the same.

So, minimal...depending on the set up.
Id like to keep things simple as best I can and get spares that are common vs. getting some weird stuff that you cant replace in a pinch.
However, the spacer option doesnt seem too bad provided the inners are obtainable. Since the ball end will need to be free'd up any way...just a bit more effort.

The spacers I am running are wheel spacers, FYI. 60 front axle with 1.5" wheel spacers.

You can also get a different back space on the wheel which will have the same affect as spacers.

Popular belief is that which ever way you do it there will be more wear and tear on the wheel bearings and any steering problems will be exaggerated.

I am going against the grain here and am trying the notch. This is on the "Baja FJ45" that is a flipped to driver side drop 60 housing every thing is cut to hell anyways so why not give it a shot. I will get some pictures up for you guys.

 

[Mace]

Right on Justin!

 

[RustyNailJustin]

I don't know if I would go as far as to call this "hardcore" but thought I would contribute to your thread
It's on the 3rd page of this build "Baja FJ45". This will give a little history of why driver drop and such.

Justin, you can outboard the springs a little bit to get axle centered and still be able to run the shackle thru the frame. I would bet there is at least a 1/2" of wiggle room. The springs also will not care about a 1/16" Looks good.

So, If I were to usse the spacers on the 40 housing (2 spacers?), would I then be able to use the 60 series longs?
This isnt terribly clear to me....
It was stated above that it should be ABOUT the same width of the 60 housing...
I might do this if I can run 60 inners...

If you run 2 spaces on a 40 housing you would run one stock length FJ60 long side and one longfield shaft FJ60 short side.

A spacer on the long side of the 40 axle will allow you to run a 60 series inner. The spacer on the short side of the 40 axle will require the same custom inner shaft that is required on the 60 axle with the spacer. 60 axles are wider than a 40 axle by ~2.625" on the long side only.

That is what I figured, but I wasnt sure...

Yea same thing I said just worded better Good job ewheeler

Per your advice I messed with the spring location and got her centered. Looks good should work. Steering now.
