Hi guys...
I was on here a few years ago,got lost and now I'm back again!
I fab my own junk, weld with Mig & stick, bend tube, do body & paint...done some engine swaps etc...
Just a regular enthusiast like most on here! Still LOT'S to learn thank God so it's all still fun!!!

I'm making some rear axle choices right now, but I don't have all the needed info to make a solid decision.

Heres some info on my truck....74 FJ 40
I'm running a 205 behind a T350/SBC. Stock axles and leaf springs. Center T bar on the list for building.
Willing to do a spring flip for length issues. (Next 'to do' actually...)
35x15.50 SX's.
The rear tire sidewalls seem very close to the inner wheelwells, being just bolted direct to the axles right now.
Don't really want to run big spacers.


OK...some stupid but honest questions... :o

1) It seems I COULD swap the axle around to run the pumpkin on the drivers side. Will this give me acceptable DS angles with about a 4" lift?

2) I could fab a centered diff from PU axles. Exactly which PU axles (and year) am I looking for to get an axle thats wider than a stock FJ40. TECH site left me a little confused on the centered diff thing...

3) Could an FJ60 or ? axle be reconfigured to get the diff even closer to the center by just Shortening ONE side and maybe using my long 40 axle in place of the long 60 axle?
Not sure where the total width would end up on that one.

4) What ARE the widths of the various FJ type axle housings anyway? Are 60's wider at all? I THINK they are but...?

5) Brakes... I have all the parts to do a disc swap...but now with the 205, no park brake. (Linelocks are a no no for street driving)
I have my brks made for the Monte calipers...will a parking brake equipped caliper interchange with those, and if so, what exactly do I need to buy!?!?
(If I went with the PU axles I could use the PU brakes as well I guess...but then I'm stuck with the disc parts.)


I know...lots of stupid questions, but I think they could be of use to others building for the first time as well. Nothing worse than spending the bucks when your not sure on just exactly the best route to take!

Hope you can clarify some stuff for me and potentially others!

Thanks guys...
 
FJ60 axles are 3.5 inches wider however the short side is the same length as fj40 axles so to cut down a 60 housing will yield you right where you started. Making a centered rear end with mini outer seems pretty straight forward, as of years I'm guessing 79-92=>?. Solid axle front minis stopped in 85 or 86 but I think the rear ends stayed the same for some years after.
 
stock FJ40 rears are 55" WTW, 60's are 58". 1985 -older mini rears are also 55, 86-newer minis are 58.

I just made a custom cruiser centered housing with mini outers...very easy I thot, article pending for Toyota Trails.
 
why not just run a mini truck housing with a v6 third member? is it not strong enough?
 
Cruiser's with fine spline have a stronger ring/pinion setup and a stronger carrier...even the toy V6 centers are prone to damage....you never hear of a cruiser ring-pinion stripping.

Plus, frequently, there is $$ invested in an existing locker, so a hybred may make sense.
