Since I'm going to be running GM NP203/205 t-cases, I am in need of a rear axle with centered differential. I have two rear 40 axles that could be grafted together to do this. I've seen somewhere (TT?) that someone makes housings that are modified. Moser Engineering is not far from here, so I could take two long side axles and have them shortened and resplined, could I not? What are the pros and cons of this idea? One challenge that is completely overcomeable (if that's even a word) is that one of my rear axles is 10 spline, since it would be shortened anyway, is it the right diameter to be resplined with 30? I would have to guess that 30 spline long side axles could be had for not much money. Thoughts from the gurus? Thanks, Luke
How hard is it to make a centered diff rear axle???

If you want to stay Toyota, run a mini rearend or go the mini/TLC hybrid route. Both use mini axles, and both provide you an e-brake. I got a mini/TLC hybrid axle housing from John Groves, and installed axles & brakes from an '88 mini and diff from an LC.

We make one using mini truck outers. It uses your center section and locker. You get the benefit of e brakes at the wheel and no c clip. It's not that bad to do if you want to do it yourself. Call the shop sometime and we'll talk about it. 970 874 1272

Thats wild, what do you use for shafts, mini shafts?

Using the mini hybrid the advantage to me is gaining an axle-mounted e-brake. You also retain the ability to swap diffs front/rear.

The housing uses the stock mini rear axles. They are the same diameter as cruiser shafts. The benefit is you get to use the stronger, cruiser ring and pinion. And if you already have gears/locker you don't have to spend any more money.
Shortening cruiser shafts weakens them to the point where they break easily. Moser can't build new shafts because the sealing surface on the LC axle is bigger than any axle stock. They can build them to the inside diameter of the old (69 and earlier) cruiser axles with the press on sealing surface. Still, that's a pain and more costly than buying / building the housing like the one we pictured.
Another cool thing:
You can use air actuators on the levers for the parking brakes making them steering brakes.

Well, I talked to Jeremiah on the phone this afternoon and ordered up a new housing. That just looks like the best solution to the problem. Only have to carry one spare axleshaft, can reuse center section, does'nt require the sale of first born child to finance it...etc. Proffitts Cruisers rocks. In my limited experience in the LandCruiser community- I have yet to run into anyone that is a jerk or weasel. I'm sure it'll happen eventually, but I am so glad I got rid of my last Jeep and switched over to the dark side. :flipoff2: Luke
The splined part of the pinion is identical (fine spline ones). I use a toyota pickup pinion flange on my front cruiser diff.
As for a centered rear end...I prefer this one... (2nd pic...explanation further down)

I never have to worry about breaking off my pinion and have plenty of cheap spare axleshafts (never broke one yet though).
What about rear discs and retaining the e-brake/cutting brakes? Is there a way that one can put rear discs on this and still have emergency brakes? I like Jeremiahs idea of air cylinders and levers for cutting brakes, but I assume that the mini truck brakes are drums and that the emergency mechanism is used with the drums. Safe assumption? thanks, Luke
