Has anyone here done an axle swap with Land Cruiser FJ40 axles? Both the differentials are on the passenger side and they are tough as hell. I hadn't heard anyone on this website talking about it so I didn't know if it was a popular swap. Thanks for the info.

You'll want to get a FJ60 front and a Toy 4x4 V6 rear. Thats the strongest combo and I believe the FJ60 housing can be easily modified to accept the Factory electric locker from Toyota.

Other than that, the Toy 4x4 V6 Rear is a little stronger than a D44, the tubes are bigger and you can find factory ones with 4.10 R&P and is about 60" wide.

So all that needs to be done is a bracket swap.

In the near future doing a swap with FJ 80 axles.....Bought a rear axle already....I think the FJ 80 rear axle is as strong if not stronger than the FJ 40 Toy V6....Plus most FJ80 axles are full floating. The guys i am getting to do it say it won't be a problem...If you can weld.

Give that man a cigar !!

definatley do FJ80s if you can. A lot of the mini truck axles have to be converted over to full floating as do most FJ60 axles unless you find the rare HD versions usually from different countries (actually some FJ60s came with Dana 60 rears the 1tons) The Fj60 fronts are pretty good axles but they are heavy and the 80s are actually a significant improvement. As for rear yes the FJ60s can accept the e-locker with some mods or with no mods you can throw in a FJ80 axle your choice and you can usually find those axles for about a grand with lockers. Good luck.

The original post was talking about an offset rear too right?:confused: I believe the V6 toy is centered

The FJ40 axles are pretty strong for stock. Later front ends came 30 spline inner and outer and rears were 30 spline also. The axle shafts are 1.5" diameter so they are comparable to 60's. The weak part of the axles are allegedly the pinions, and on the front obviously the birfields. I believe the pinions are 27 spline on the later ones.

I run a stock FJ40 rear on mine and have only broken one axle shaft. I run a hybrid dana 44/ with a FJ40 3rd in the front. I break 44 shafts and joints all the time.

I am running 350/465/3spd case and use the throttle alot.

FYI in the future when asking about landcrusier axles you might be better off asking in the landcruiser section :flipoff2:

I was asking in this section about whether anyone had done the swap before or not. I know about the axles I just wanted to know if they would work or not. And the axles are both out of a FJ40.

FJ40's are too narrow. FJ60/80 are the way to go

arent some fj axles high pinion? if so which ones?

FJ80 axles were high pinion, and the diffs were toyota 8" not the larger style of older land crusiers (40s, etc).

high pinion front and rear?

i believe so but i am not 100% positive, better to ask a crusier guy ;)

FJ80 front is 2" higher than Rover

FJ80 rear is 1" higher than Rover


I am sure that Ruff or BJonRoids would be of more help though.

I forgot about the center drop on the Tacoma rear ends...

Go with the FJ60s, there are a wide veriety of lockerrs and gears. The only thing you have to worry about is the birfields on the front axle. They have a emilinator kit, but unless you running a 350ci with 35" Tyres then you should be just fine.

I think the 80 Series axles would be a better choice. Birfields are EONS stronger than the older 60/40 series and you get the hi-pinion differentials, as well as optional factory electric lockers (1993-1997), a decent variety of aftermarket gear ratios, disk brakes on all fours and a FF rear to boot. Not cheap, but probably cheaper in the long run than sourcing a non-US 60 series rear FF axle and converting. I've seen several rovers running Cruiser running gear on Aussie 4x4 magazines, that might be a good way to start.
