ARCHIVE Toyota Rear Full Floating Axle Flanges!

[Dan Fredrickson]

I held off making these items for a year because another vender made them and promised me a fair price when I needed them.

When I needed them his fair price turned out to be about 6 times what they cost to make. It seems he just wanted me out of the market for a year. Well, I guess he got what he wanted but I don't believe in false promises.

So here are the flanges that can turn your rear axle into a Full Floater and they are from Ruffstuff!

This is a weld on Axle Flange to mount Front Toyota Mini, Fj40, or FJ60 spindles to the rear axle. The caliper bosses are made to use the IFS Truck ('86-'95) calipers and FJ40 or FJ60 rotors.

These are 1" thick and made from 44W Plate & cutout for the 3.5" axle tube used our Axle Housings. We will release a 3.25" & 3" version in a couple of weeks. These are $195 a pair, not the $300 price I was quoted from the other vender originally...

This looks like a great idea. So the factory flanges are cut off and these welded in place? Obviously you'd need the spindles and rear FF axle shafts, but what else would be required to convert?

This would be a great way to go if the differential area of the axle housings is the same between FF and SF, as it would allow use of lockers and LSDs built for FF axles. Given the decreasing availability and skyrocketing prices of complete FF rear axle assemblies, it looks like you're onto something here.

I'm saving pennies....

What do you use for axle shafts? Do they go on the factory FJ40/60 axle housing, or something else? Seems we need more information here. Pics installed?

 

[Tapage]

great idea, price and option ..

 

[Dan Fredrickson]

The price is listed at $195 a pair...

They would use a front hub, custom shaft, the listed calipers & rotors...We do not yet have them in the smaller diameter for the stock axles, only 3.5" for our or other custom axles so far. We will have 3" & 3.25" after the 1st of the year...These have been in use for years but the availability was pretty limited.

THis is a great idea. Keep up with the Innovation!

With the use of front hubs, a set of drive flanges and some Longfield shafts you would be in business.

The only thing you need now is someone who will machine new hub housings and spindles.

Although, you could run mini truck spindles and housings which are far more plentiful.

Damn, this is so tempting.

It is supposed to be tempting

You should make one to fit a sf 80 rear axle to convert it to ff using stock 80ff shafts

 

[lovetoski]

If welded to an fj60 rear axle, what increase in axle width would be expected?

Also, would OEM FF axles work, or would they need to be custom?

 

[Dan Fredrickson]

Really both the same question...

You could do either, all you have to do is decide where to cut the existing tube

 

[fj-rankenstein]

i guess the better question would be,

if i cut the ends off of my 60 series semi floater axles and weld these on, will the axle tubes be long enough to use oem 60 series full floater axles??

or will i end up with something too long (which isnt bad because i can always cut to match..) or will i end up a little short?? (which will force me to either make extensions to widen the axle or end up with some goofy shorter then oem 60 series axles??)

either way, this is an awesome thing and i am definitelly in for a set when you have the 3 inch ones made..

Now thats a better question, I am going to have to think about it and do some measurements...My first thought is they may be ~1/2" short but using front hubs would make them longer...And the benefit of rear discs'...

Thanks. Your answer makes it very clear what to do.

 

[Dan Fredrickson]

Thanks. Your answer makes it very clear what to do.

It is pretty cut and dried. Its simply a comparrison of measurements. Front hubs are going to be farther from the axle tube itself so when choosing a length it would usually be cutting the axle tube shorter. If you wish to go wider I think a new housing would be more in order rather than extending a stock housing.

Looks like Friday we will build a couple of axles for my 45! Toy 8" front with Hellfire Fabs FJ80 knuckles and a Ford 9" rear with 31 to 30 spline shafts using these and Aisian lockouts. Of course they will be using our Axle Housings...

 

[Dan Fredrickson]

3 More sets out this week!

 

[Dan Fredrickson]

Here are some pics installed, they are on one of our 9" housings I am using in the rear of my FJ45 pickup...

Just the flange...

With the spindle...

With the Hub, Rotor, & Caliper...

Its really a pretty simple operation and this is just about all the instructions anyone will need. Of course I am running 31 to 30 spline shafts but they are damned easy...

 

[Dan Fredrickson]

Here are a couple of questions from another site that help explain these a bit better...

I like this a lot. I like the ease of redoing full floating axles. Once the actual lenght of the inner axle is figure out, I might have to get me a set...keep us posted.

The axle should not really be too much of a concern. It would be great if you could use a used front inner axle but I would say build it to the length you want and don't compromise by building it to an existing part...

Since these are weld on flanges, what dies one do about the 4-bolt mounting area? In other words, what is the best way to center these flanges on the axle and weld to?

^good question..how do you true it all up....maybe a rod all the way thru the axle..

You would remove the 4 bolt flange, it isn't used any longer. You would be using double splined axles like front inners.

We install them using a trubar but a simple instalation trick would be to use a long (5') piece of heavy DOM or 3" angle iron and 2 machinist squares. Clamp it about 3" off the faceplate and setup the correct length and then with the machinist squares true them to each other. Pretty simple...
