What axles are these?

[Barathrum]

Guys, I was just wondering if you could help me identify these axle assemblies. I picked the up from a mate today but he has no idea what they came out of and neither do I. They are believed to be landcruiser, but not sure on what year? On first inspection ratios appear to be around 3:1? Are they any good? How strong can they be made? They were the right price, ie cartoon of beer cheap and supposed to be reconditioned. So any ideas on what they are? Or how I can work out what they’re?

i would so that they are 4.1 ratio 40s
mainly because the rear is ff
so
40s with 4.1 thats my best guess
worth a cartoon Maybe i would buy them for spares ( if i owned a 40)

83 lux is right, they are 1977 or older 40/45 series axles.

Note the bellcrank steering linkage and the shape of the pinion flange.

Thanks guys

I know very little about yota's. How strong are they? Say compared to stock hilux or something like that. I'm guessing the rear wouldn't be to bad being a full floater, but what about the front?

[beanz2]

Same CV joint as the Hilux so no advantage there, but the crown and pinion gears are larger.

The disadvantage is the pinion angle. Cruiser diffs are meant for spring under configuration. Mounted in a spring over position, if the pinion is positioned to point to the transfer output, the caster angle becomes negative and you'll have scary handling. To properly use these in a Hilux is either to keep the pinion flat (and you get sharp driveline angles at the uni) or to cut and rotate the ends to regain the positive caster angle.

So Hilux cv's will fit. Will 30spline longfields? With these combined with the larger crown wheel and pinion make a strong setup?
If i was to cut and rotate the knuckles then the caster is going to remain ok. Pinion oiling will be a problem, but as i'm thinking of using these in a buggy then traveling distance at high speed wont ever happen, so oiling wont be much of an issuse. Or will it?
What can be done about converting the front to disk brakes?

[83 lux]

ok
You can get 30 spline longs to suit

BUT they have a 10 spline pinion
WEAK AS PISS
so your not gaining any thing by using THESE diff
they are a little narrower then lux and you are losing diff clr.
So if you have lux diff use lux diff
but FYI if you can find 60's diff use them they are stronger them 40 wider the 40 and lux and have a dics brake front end
All these things you have to look at when building a buggy.
KEEPING COSTS down.

hope this helps

yeah ok that's all i really wanted to find out. I was considering these as an option under my zuggy but if they're no good than i wont bother. I originally wanted some 60's but these were just sitting around so, I though i'd just grab them and then find out what the go is.

30 spline Longs need a little grinding from the housing ends, but yes, they can be made to fit. I have 30 spliners in a 1975 housing.

Agree, the pre-1978 pinions are weak, but any non-Bundy cruiser diff centre until 1989 will fit. 1990-1997 rear diff centres will fit. These have stronger pinions.

I'd point the pinion up to the point where the bearing is just below the oil filler hole in order for it to receive lubrication. Or, put another filler plug higher in the pumpkin.

For discs, you need swivel assemblies from a lux or a disc brake 40 or 60 series.

Yep, a lot of work needed.
