i was just wondering if anyone knew where and how much it would cost to have a custom front axle built for my 100. Having people swapping out for a solid axle is raising my grin....

How much would it cost/which company can build:
Solid axle to match rear width
80 front diff
100 brake/hub set (100 serviceable parts)
80 knuckles(80 serviceable parts)

Only thing custom would be the axles and the housing and would it be possible to adapt the 100 hub set into a 80 knuckle.

Or if that set up cost an arm and a leg just have the complete 80 hub set, but rim/hub center bolt pattern match the 100.

Just thought I'd ask.
 
Ruff stuff housing with 80 series knuckle balls with RCV custom length inner axles and you have a good axle for a sas 100. But instead of an 80 series third, I would use a 9.5". No reason to spend all that money and still have an 8" ring gear... Housings start at like $700.
 
Diamond axles maybe as well?
 
Thanks will look into diamond as well.

But I was just thinking if I were to just buy a front 80 axle and lengthen it 3 inches, buy RCV custom length 80 axles....

And for the rear would I just be able to re tap and drill the axles to allow for the 6 lug?
Is the rear inner wheel hub the same as the 80?

I'm just looking at different options on removing the ifs without having to re mock the rear for an 80 axle, since the 100 axle is 3 inches wider than the 80.
 
Okay forget lengthening the axle housing, I could just run 1.5 inch spacers on each end.

How about tapping the rear axle for the 6 lugs? rotors too.
Or custom rear axles with a 6 lug and modified rotor(or will the 80 rotor fit same dimensions as the 100 brake unit).
 
Expect $3500+ for a complete custom front axle with custom length RCV axle shafts. I also agree with using the 9.5" but that will add more cost. Running 1.5" spacers to match the rear won't cut it unless you are willing to run wheels with a different offset front to rear. The 80 axle is roughly 5" narrower than the 100 axle.

Dave at 4plus has sleeves to lengthen a fj60 axle housing. With a little bit of machining they could work to lengthen a fj80 housing. As in like 5 minutes on a lathe. Each sleeve adds about 2 5/8". I think a 100 series is 65" wide, so you would only need 1 sleeve, a 80 axle assembly is 63". Cut off one birfield ball, have a sleeve machined a bit to fit, weld it in the housing, weld the knuckle ball back on, get a custom inner shaft from trail gear made and your set. To get different lug holes in the rear shafts or rotors, a machine shop can modify that stuff easily too. I would recommend going with a 9.5" diff though if your more of a hardcore wheeler.
 
To run the 5x150 lug pattern up front you could go with RS front axle, 105 knuckles (@ $900/pair) and keep the stock rear. This is in addition to any costs you will incur with regearing, locking the front axle, and rebuild. It gets pricey pretty quick.

The more cost effective method is try and change the bolt pattern for the rear to Toyota 6-lug. Or just run 80 axles all around :)
