Can a semi floater be converted to a FF axle?

Awesome.

Plenty of folks besides me really appreciate when a vendor chimes in on technical discussions. Thanks. :cheers:

Yeup!!!
 
Any one on mud do the Ruff Stuff conversion yet? I recently picked up a FZJ80 locking 3rd member and would love to have it in my 40's rear axle, disc brakes would be a bonus. I saw the vendor's pics- hardly a well documented write up
 
Same approach as rough stuff but I don't cut the axle so the result is about 5.5" wider track. The positive points are that they are self squaring to the factory ends and I use the wheel bearing pocket to install
a marlin crawler birfield seal to help keep the diff oil in the diff. i actually built these about 7 years ago but only used them in shop. I wasn't sure anyone would want to engage in a project this involved.

I like this design a lot better than ruff stuff. Those self squaring sleeves are slick! So if i wanted to stay stock track width, I should cut off about 2.75" per side. What calipers, rotors, wheel bearings, spindles are needed? I would like to use 70 series axle shafts fir the elocker. I guess the biggest question is are you willing to sell these? If so how much?
 
Those sleeves are the stock ends with the backing plate flange cut off.
I don't think cutting down would work with a stock axle tube. The stock tube isn't round by any means.It's two hemispheres seam welded full length. Toyota bores the ends of both front and rear housings and inserts ends. A steering knuckle up front and a bearing retainer/ backing plate flange in the rear. I suppose a good machine shop could chuck up the housing, cut the end loose, cut the tubes down and rebore the tubes to accept the ends. The only reason these self align is because the ends of the tube are machined and squared from Toyota.
Ruff stuff is building around custom housings with DOM tube which is very round. I suppose you could use my plates on 3" DOM since the center bore is 3.04" but I would still advise boring the end of the tube to accept some kind of seal to help prevent gear oil from washing out the bearings. I ran into this about 15 years ago putting plate like this on Dana 60 centers. You had to repack the wheel bearing a lot and oil would seep from the inner hub seal and dust cap on the drive plate.
 
To clarify , our flanges look very much like rough stuff. Ours are bored to fit over the machined end already part of the axle. The 40, 60 and 80 housings are consistent with this measurement. The fact that the axle ends up 5.5" wider was a compliment to the sleeves that I make to widen the front. The sleeves
are 2.75" each so the front matches well with the wide rear. Like I said , I wasn't actively marketing these but if a customer wanted a stretched and widened 40 or 60 this is a possible route so. That being said, everything is for sale.
Ruff stuff, on the other hand, is building around custom center sections that have big strength advantages over the stock center section. That setup would be sweet. It's the same reason that I started doing these around Dana 60 centers for the customer that wanted the monster axle tubes.
There weren't many axle builders doing custom LC center section when I did these. If Ruff Stuff is following this thread maybe they could offer the flange with a short stub squared and welded to the flange making alignment easier for the DYI guys.
 
Any one have a pic of a 40 with widened rear track? 2.75" per side is not too extreme, really it is the realm of wheel spacers and offset rims
 
It's pretty common to run a 60" track when you run large tires. Technically 35's are as wide as you can run
on a 40 without hitting the leaves on full lock unless you run your steering stops out. I've run 39's on a 60"
track with full turning ability

I am only running 33X12.5Rr15s
 
It looks like SOR has the stuff in stock. I am just trying to get some cojones and spend the cash.

If you want stock width contact Radd Cruisers. I believe the BJ74's had a factory floater disc rear and were same width as a 40. John could tell you for sure
 
This sort of goes with this discussion.

With a rear disc brake mod, if you shear the axle shaft at the C clip won't the brake rotor/caliper keep the axle shaft in place?

I'm considering building a SO rear axle and thought I would study up on a FF conversion. Kind of hard to justify the cost...
