Does anyone know if it is possible to put the 3rd member from an FJ80 into a later model FJ40 Disc Brake Front Axle? Would the bolt pattern align to the axle housing, would the spider gears align to the axle shafts, and would it require any modifications to the axle housing?

It would need to be a rear third and some modification is required but it's do able. There is a good write up here somewhere if you do a search.

Thanks, finally found it. https://forum.ih8mud.com/threads/elocker-install-40-series-ff-rear.270721/
You would use a rear 80 in front or rear 40 housing

Stop calling it a "FJ."
Hi all,
mdman, the front diff on a 80 Series is smaller (8 inch) than the rear (8.75) which is the smae size as earlier TLC diffs.
So no, the high pinion front differential of a 80 Series won't fit/work in the front axle of a 40/45/55/60/70/75 Series.
Regards,
Alan

I was told my front axle is a fj80 low pinion the driverside axle tube is bend so bad I cant get the axle out I have an ARB and I have access to a fj40 front axle I want to know if I can put my 3rd member into the fj40 front so I don't have to buy another arb. Or does anyone know where I could find a ffj80 front axle housing? any help is greatly appreciated thanks in advance
