Where to get a FF rear...

[Mace]

If I remember correctly, that case involved the "C" clip slipping off the end of the axle thereby allowing the axle to slide out of the housing, not a broken axle.

either way the end result is the same
The wheel walks away.

But, a rear disk brake conversion helps prevent this

I was also thinking of the article Billa wrote. He talks about the neck down style as being structurally sound. Then goes on to comment on the "weaker" kneck down style front 60 inner shafts..

Kinda contradicts himself.

So yes there are benifits to a FF rear axle. Personally I think that if you are going to be runner 35's or less they are not worth spending the money on. OK maybe if you are carrying lots of heavy loads, I can't imagine how much you would need to carry to make it worth it, especially with a 2F.

But to each his own.

Jason,

On the full floater axle it is a constant diameter the entire length, from the splines to the flange (has it been that long since you helped me with my junk?). This allows for even torsional elastic response along the entire length of the shaft. If you would have studied structural engineering instead of H20 & rocks you would know that when torsion & bending are combined the forces multiply based on the loads (I do not remember the exact formula). a full floater is probably no stronger torsionally (I'm sure toyota designed the SF shaft to be capable of the same torsion loads) but is a better design to evenly distribute the torsion, therefore can handle greater short term (shock) loads.

a 14b would kick ass but then you would end up with an 8 lug rear & 6 lug front & a MUCH heaver rear axle with limited clearance... I'm happy with my FF & have yet to break a shaft while it is parked in front of my house

I got a pile of broken shafts here... all from 33's or 35's.... better make that statment 31's or less

I remember the design and I understand why it would be slightly stronger. But nothin major
they do make a SF 14 bolt ... whatever spline count you want


I take it back, Anyone that wants to go FF let me know, I'll help you in exchange for the old SF shafts and housing

It's a crappy pic, but this is the short side out of my old 60 series FF rear and you can see that the shafts diameter is indeed constant the entire length with a slight increase at the flange end for the seal surface:

BTW, the do make Alloy 60 rear shafts now

Wonder which is stronger, FF or alloy???

 

[lowtideride]

oooo can o worms Mace.....My vote is the Alloy

Or Alloy FF shafts

BTW, the FF ones are cheaper too...

 

[Mace]

Ahh but then you have the money out on the shafts AND the FF housing

Maybe Bobby Long can do up some chromoly FF axle shafts
