Turn your sf axle into a ff (1 Viewer)

[RLMS]

here is a shot of the spindle!

here is what we will use for the inner seal. On a note, these are designed for DOM housings. But the idea of using one and applying ample rtv on the surface with the 3 o-rings should do the trick to seal a factory housing....rear FF.

we will also be using these on the front ruff stuff housing. No more leaks, no more leaks,no more leaks...

update?

 

[RLMS]

Update> the rear brakes are from a 79-85 front toyota pick up, that includes the rotor,caliper and wheel bearing hub unit! Uses the same bearings! Now due to having front brakes in the rear like this your actual front brakes should be upgraded, other wise this is a poor choice for icy, wet conditions even with a pro valve turned all the way down. As for the shafts we will be using custom length Long field inners and drive flanges. One could Put a Aisin Hub on the rear if so inclined!!

Taco brakes in the front?

Taco brakes in the front?

Would that work?

The Taco uses a unit bearing hub which the rotor isn't bolted to like on the earlier trucks and 'Cruisers where the rotor is bolted to the hub that contains the tapered roller bearings.

thought i had read where someone had figured out a way to use them on the older axles?

correction, Tundra brakes are what i was thinking about i think?
like Bustanutely did here- https://forum.ih8mud.com/showpost.php?p=7530685&postcount=153

here's some info on using taco brakes-

I used the Nitro axles for my rear diff, cut to the length i needed, these axles have the seal surfaces built in at the flanged end.
I used 80 series spindles welded onto a 60 series housing, these have provisions for seals in them at the threaded/nut end.
I would think the 80 series seals could be used in what ever Toyota spindle you use without to much trouble.

Front Range Off Road Fab also makes a kit to adapt Taco Brakes.
I used this kit to mount Tundra brakes to my 60s front diff.
With the Tundra stuff you will need a 17" wheel or a large spacer though.

Do you need 17" wheels? Tundras can be ordered with 16" wheels.

 

[baxter650]

You may be right, the 16" may fit, but i knew the 17" would for sure.
There are also two different Tundra calipers and i am not sure if they are bigger.

Yeah, I'm not sure either. I'm going to give it a shot with my 16.5" wheels later this year and see if it works!

Redline, can you tell us how much the FF conversion widens/narrows the rear end assuming you cut off right at the backing plate for the drum brakes?

I totally would but we used a custom width ruff stuff housing!

Ill check the width for a factory housing here when I get a chance!

Couldn't the bearings be run "wet" like a Dana60 (or most rear FF for that matter)? Don't know if the fluid level runs high enough in the housing to keep the bearings wet, but it would solve the inner axle seal problem.

Just a thought...

 

[baxter650]

lefty b: This is what i did in my PU with a 9" center and Toyota spindles and brakes.
Used Strange axles and Toyota drive flanges.
I had to raise the fluid level in the diff some but it has worked fine for me.
I do have some weeping from the dust caps on the flanges so i will be silver soldering the caps to the flanges later on.

this seems like a good idea, also why not run flanged axleshafts that just bolt straight to the hub?

 

[Mace]

flanged axleshafts are more expensive to make. A single (mostly) diameter shaft is much easier and cost effective to make.

 

[mookie]

Roger that.......

would 80 series full floater shafts mate up to the front hubs if you cut the housing tubes to the appropriate lengths?
