This cruiser has been on Aussi eBay for some time now:
1970FJ40eBay.webp

And this is what the seller claims:

FactoryConstant4WD.webp

Has anyone got an opinion on whether "factory constant 4WD" was really available as an option back then?

Surely such a "special delivery" would cost more (because it always costs more to separate one product out from a production line to be treated differently)?

And why would anyone pay more .... to get less....(assuming no transmission modifications are used to combat the "wind-up" and "extra tyre wear" that an FJ40 would normally suffer from if left permanently in 4WD).

I'd have thought that to get constant 4WD you'd only need to throw away some of your normal shift linkage.

All views welcome....

Used car salesman who thinks they “know” Land Cruisers.

Vehicle does not have lockouts on the front axle, so, of course, it is going to have a “very rare factory constant 4wd 3 speed manual – was a special delivery” configuration that someone will have to pay extra for.

:lol:

Just more used Land Cruiser parts.
 
My other car is a Daihatsu Terios (constant) All Wheel drive, also known in Japan as a Toyota Rush. See also: -► The new Toyota Rush is a sporty compact SUV.....
It has a third (central lockable) differential between the front and rear which can be (electrically) switched on/off or in/out whatever you want to call it.
Works beautifully!

Yeah. I was sceptical too Steve...

There was a "full time 4wd" ... Two trucks that I know of exist

There is a thread or two about them on mud... That truck is not one of them :)
Thanks Johnny

Well I was so disbelieving that I never thought of searching ih8mud. So here goes ...

Well I found this thread ...
https://forum.ih8mud.com/40-55-series-tech/16826-have-you-ever-seen-76-fj40-full-time-4wd.html

And skimming through it, I think the conclusion was not in favour of a full-time 4WD coming off the production line in the 1970s... Or did I skim too fast and miss something?

had one in our family with the same set up,full time four wheel drive,lots of 80 series had it also,not uncommon

I know full-time 4WD came later (after the 40 series was finished).

But was it really available (with a centre-diff) off Toyota's 40-series production lines in the 1970s?

I find that very hard to believe!

:beer:

PS. And just to make this clear... Freewheeling hubs have nothing to do the argument (whether they are present or not)...:lol:

no centre diff,it just had no free wheeling hubs,actually i threw out 2 new front hubs this year off our old tojo
 
Yes Tom that's the one

It was made by Toyota ... Not sold to the public ... Prototype trucks using borgwarner full time units... Concensus was it was made.... Not mass produced... A few one off trucks

I did some major digging into them thru toyota and Borg Warner but could not find any additional information ... Yet

Off production line.... No ... In 1970 ... No ... that one you posted poser explained it

It appears it was for sale here. https://forum.ih8mud.com/az-copper-state-cruisers/89487-fj40-sale.html I wonder where it is now.:hhmm:

Thanks for this Aussi FJ40.

I can see how this confusion occurs.

When I get out from the cab and start fiddling with my hubs I'm commonly asked "Are you putting it in 4 wheel drive?".

The easiest answer is a simple "Yes" so that is most often my reply. I guess I'm basically a lazy bastard with speech. (Quite different with words when I hover over a keyboard 1st thing in the morning though. Then verbal diarrhea proliferates as you can see. He he.. )

In my mind though, I never consider the hubs as being part of "putting a vehicle in 4WD".

They are simply an accessory (that is largely unecessary IMO) that allow you to disconnect your front differential from your wheels for the purpose of reducing wear (and/or saving fuel) when travelling on the highway with the transmission set in 2WD.

So to me (and I think most of my generation who have owned 4WD vehicles since our teens), the transmission levers in the cab are really what you use to put your cruiser in 4WD.

To understand us, you probably need to know that back in the 70s (certainly where I lived) freewheeling hubs were rare. They were not sold with new Land Rovers for instance, and Land Rovers dominated the marketplace here. So I still think of normal 4WD vehicles as being without freewheeling hubs even though everyone these days (including myself) have these silly things.

(Incidentally, here's some trivia.. If you wanted freewheeling hubs for a Landrover, the ones the dealers sold in the 70s were made by British company "Fairey" that was originally formed to build aircraft. So they were always referred to as Fairy Hubs. Not very Macho-sounding is it?)

So I think we've probably identified what the seller here is thinking too... (It has no freewheeling hubs and therefore it is full-time 4WD.)

:beer:

PS. Our different backgrounds give us different meanings to terms so there is really no right or wrong here.

And I thought of whether it was fair of me to grab someones advertisement and dump it in a thread (and be critical of it)... But then I console myself about this by thinking .... The ad is in the public domain. (It is not in the least "private".) The seller is claiming he's selling something rare (presumably in order to either get more interest or get a higher price). So he has a duty to potential buyers to get his facts correct. On this basis ... I think it is reasonable for me to start a discussion on his claims... Sure I could ring him, but it would cost me overseas phone call, and judging by the thread I linked above, I may still end up confused at the end of it.

Without photos detailing the rare Toyota-designed features .... or without official Toyota production records ... we have no evidence of anything being rare here...

(The seller should be showing closeup/clear pics of what makes this cruiser rare ... if it is rare.)

PPS. While I have freewheeling hubs, they are almost always left in the 4x4 setting because I like to imagine the oil and grease in my front-end getting churned up to lubricate everything properly and develop a bit of heat to evaporate out any moisture that may have creeped inside... (My thinking is often anal.) They are only disengaged for long highway trips.
 
I have a pair of Fairey lock out hubs on my 79 FJ40. I have never figured out how to take them apart to install the cir clip.

That 76 full time 4WD had a different shifting setup. I was told about it when the original poster bought it back in the nineties. I have some pictures saved some where.

I'm actually sceptical of this 1976 one being an official Toyota prototype too.

Uplifting this from the ForSale thread:
I have a very rare FJ40 for sale. I have always intended to restore it but with 5 kids since I bought it I am just not going to ever get to it. It is a 1976 with full time 4 wheel drive. I was a factory prototype that used the same transfer case as the Jeep Quadra-rac. It has the appropriate info plate on the glove box door with instructions for use. I believe that this 40 has 4000 miles on it. When I got it 10 years ago I took it over to my friend Dave Gore's house and he noticed it had 2 of the original bias ply Dunlops still on the vehicle 20 years later. It is in need of paint, seats and carb rebuild. I am sure it has a few more detail problems as well. If you are interested in this 40 please call me at 623-337-8445.

So it uses the same transfer case as the Jeep Quadra-Trac?

From Wikipedia, the first version of this was the Borg Warner BW1339 transfer case, built 1973 to 1979, and incorporating a chain drive.

Possibly Toyota experimental engineers may have fiddled with a Borg Warner transfer case in one of their 40-series. But I think the term "prototype" should be reserved for when Toyota has made something of their own (which, in keeping with their usual quality standards would have ended up superior than the Borg Warner).

But even this lacks credibility for me.. Why hasn't anyone shown pictures of this Borg Warner transfercase installed? (Is the installation THAT unprofessional??)

(And this Borg Warner transfer incorporated a chain drive for heaven sake!)

And why would Toyota even seriously consider producing a so-called "full-time 4WD" when that technology wasn't yet in demand?

"Full-time 4WD" (with centre diff) has only two possible advasntages from where I sit:
  • It is cheaper to produce, and
  • It suits the lazy non-technical driver because locking the centre diff (and thus equipping the vehicle to drive like an ordinary cruiser whose transfer lever has been pulled back into 4WD) can be achieved easily with just the push of button (or flick of a switch).

I believe back in the 70s, most 4WD drivers were like we (here on MUD) are now... They used these vehicles for what they were designed for (as farmers or forestry workers etc) or as hunters or off-road enthusiasts (recreation) etc. We appreciate the extra control offered by all the levers and love getting to know how to use them properly.

Contrast that with today, where we indeed HAVE the market for "full-time 4WD". Nowadays most buyers of new 4WDs buy them merely as a status symbol and they don't want to stress out figuring which lever to push where. They just want a button to push when their 4WD doesn't keep moving properly in the direction they're pointing it (which is probably up to the ski field to drink some more Chardonney).

Toyota wasn't stupid.. I very much doubt it would have put serious money into developing a cruiser for a market that didn't yet exist..

.... I have some pictures saved some where.

I'd love to see them... (They might make me eat my words and for someone with verbal diarrhoea that may not be pleasant!)

I not sure I would exclude the word proto type because its a Borg/Warner transmission and transfer case. Allison Transmission, Dane axles and transfer cases, Cummings diesel engines. Used in many production vehicles but before that happened I'm sure they were a proto type. In 1973 Jeep introduced a full time 4WD. If Toyota thought about competing with this the idea of then considering using a Borg Warner setup to get into the market quickly may have happened. A few were produced and the idea was dropped. My question is why the short wheel base FJ40 and not the longer wheel base FJ55. Jeep had it in the wagon not the CJ. Johnny has done quite a bit of research on the subject as well as a few others. Borg/Warner was in Japan and may well have had some kind of relationship with Toyota. Marv Specter who may have a good relationship with Toyota but in 1975 when these were produced he was still at his previous employer and hadn't started SOR yet. But it may be worth a call to him. If Toyota produced this, commissioned someone to make them or another company made the we may never know. I will say it hard to prove Toyota wasn't aware these being produced. These were not a complete vehicle that was manufactured and later modified. The frame was put together with a standard except a different torque tube behind the transfer case was use. The stock hole for the torque is there on the right side but a second is drilled and used a little further back. The stock hole is perfect unused circles in the frame. From everything I have heard these were donated to schools by Toyota. Only know of LHD models which to me means were planned for the North American Market. These were also a complete vehicle right down to custom stamped skid plate. Somewhere in emails I have the production date of the two. The one talked about here a month or two earlier. I do believe there were a few small chances on the other one.

First picture is the glove box plaque. I believe these was done in Japan with a poor translation or a elementary school kid in the US
Second is the transmission cover. No sign of any holes being filled and the cover has fitted metric thread bolts. In 1975 I believe the three speed was still being used but not sure a column shift was a option anymore.
Third picture is floor mat with only the custom holes.
Fourth picture is the hand brake adapted to the Borg/Warner transfer case. You can also see the stock hole for the torque tube.
Fifth picture is of the custom skid plate. It is different than the four speed skid plate, I checked.

This is why I waste whole days on here. Great sleuthing guys. I wouldn't discount Toyota sending a handful of full-time 4WD models to market. It could have been very cost-effective to get the prototypes manufactured and once done and proven, hell, may as well sell em. Let's not forget this was not the ultra-lean times we see now. Car manufacturing was still booming and there was probably quite a few R&D dollars for such things.

Though with that torque tube LITP, I'm 99% sure my stock Aussie BJ42 had one.
 
To add to this Borg Warner and Toyota were somewat close as an off shoot joint venture was another company formed ... Aisin Warner... A company owned in large part by Toyota Group.

The BW case was either a 1306 or 1308 forget which... Not the 1305

I think the LcWizard knew of the trucks and I got the number from him... Like I said either 1306 or 1308 ... BW did have something to say about that some time ago... When I'm at work I'll check what I have notes on... Borg Warner lists them with the nomenclature BW13-06


The dates of the trucks were 10/75 and 12/75
 
I know I have pictures of the other truck... Main difference was the location of the knob... One as seen here placed on the tranny hump and the other was on the dash.

Like I said ... Monday I'll be at work to get more information and pics :)

My emails date about two and a half years ago if that helps your search. I looked at mine and pictures are poor quality and up side down. Need to figure a way to save them. But they probably aren't worth it. My last email I got from the owner of the second one said it included a file of high quality pictures but they weren't there. If you got those pictures could you email them to me.

fulltime 4x4 is not a new concept FWD trucks had it in ww2 and a lot of trucks were damaged because the driver left the center diff locked .
