Who can tell me what the factory options for gearing (axle)on 62-70 FJ40's??? I have searched, but came up empty.:skull:

well, you had the 4.10's and the......4.10's. That was about it.

Actually, there are unconfirmed reports of higher ratios available as options from Toyota for trucks as early as mid-1960's FJ40's and FJ45's, but with documentation as spotty as it is, it's tough to tell. Rick D. might know more about this, I seem to recall 3.70's and 3.3X's being available as well...Heck, wasn't John Pardi selling a set of early diffs like that?

In any case, Jeff's right, *confirmed*, you gotta assume it's 4.11's. But like with most things Land Cruiser, just when you think it's set in stone, something comes back to prove you wrong! :)

When you look in the TLC faq there is probably 20 different ratios from 3.xx to 7.xx. Which cruisers came with the 6.xx and 7.xx ratios?

The reason I ask is because I aquired two cruisers this weekend, a 62 and a 63. The 63 has an odd gear ratio. 5:13 or something like that.
I was under the impression that factory gears were 4:11 or in the later years 3:73's. I have yet to see anything different, until this weekend.
The guy I got them from said he could crawl up walls with it because it was geared so low, he mentioned that he had to swap the gears out when he blew a diff on his way to alaska in the 70's. I guess the only thing to do is pull a pumkin and find out. Hopefully he swapped out both ends!
I'm assuming the 63 has 4:11, have to verify it also, but the front end hubs are not typical. They are huge, and look like they have small levers on the face of the hub. Anyone ever seen these?
Thanks for the input!:skull:

If they had two metal rods that you pull out, flip around, and put back in, then they were stock hubs from early 40s and 25s. I wish I had a pic somewhere, but I am familar with them. They also have some little metal diamonds in them which serve as grooves for the rods. I also highly doubt there is anything near 5.13 (I don't think there is a 5.13 axle ratio for a cruiser, 5.29?). My guess is 4.56 or possibly 4.88 if they were available. I've also heard rumors of 3.70 and 4.56 axle gearing available from Toyota dealers on earlier 40s but not 4.88. This is, of course, rumor.

three ratios for 1960's trucks
4.11 (37/9), 3.70 (37/10), and 3.36 (37/11) (only pre 1965). 3.70's rarer, mostly used in 40/45LV's and not offered in LWB pick ups (only 4.11)

Toyota parts books 25 1963, 40/43/45, 1961, 1962, 1963, 1964, and 65-67

4.56 AND 4.88's were introduced in post 1984 in 7X series primarily with LCII's although they have been available in full LC's later (different carrier shape as well)

source:
Toyota parts books 4X 1980-1986 (world), 6X 1980-1987 (world), 7X 1984-1989 (world), 1990-1999 7X (world)

the two swinging rod style hubs are "Denvermatics", which were common with Warn barrel style and Selectro in coarse spline front ends. All LC's up to the early 1970's were delivered (esp to US shores) without hubs. My 9/1981 even lacked hubs. A prototype style FJ55 hub was introduced (1971?) early but are rarely seen. FJ55 got the first Aisin sets around the introduction of disk brakes.

i had a pair of the early 55 proto's, but sent them off to someone on this board.

impressive info Rick.

in oz we got:

3.7 (early trucks with 3 speeds and f motors)
everything else comes stock with 4.11

the only exception is a landcruiser II which basically has minitruck running gear and was offered with turbo diesel 4.88, 22r = 4.56, and some with 4.3 or 4.11

another option ios the 6.17 gears from a stout, they fit, but are coarse spline

rick d, I am also impressed!
Well this leaves only one thing to do, pull the pumpkin look.
It seems there are a few variations between the years of manufacture, the 63 has a centered rear diff, and the 62 has an offset diff. This seems strange, unless someone down the road swapped rears out on the 62.
One other question, is it possible to put the mini disc and birfs on the early front ends.
The axle looks almost identical to the 74 and 70 front ends that I had previously. Just wondering if there was a variation in the early design compared to the later, which will accept the mini ends.
Thanks again!:skull:

early trucks also have 8mm studs instead of 10mm studs holding the pumpkin on. 2F metal fuel line has been used to 'shim' the 8mm studs to take a later 3rd member (pumpkin).

Ball joint front ends use a inner brass bushing as the sole seal between the knuckle and axle tube. These pieces (were 'sided') are now discontinued. No seal, no keeping gear oil out of knuckle. Unless you are crazy about machine work, you cannot fit the rubber seal in a ball joint housing.

with this all facing you, I'd find any birfield axle tube to work with. 10mm studs, takes the seal, and all you might need to do is grind to fit the birfield.

Ranger - why pull?

Just lift a wheel (or two if it's locked), chalkmark the driveshaft and tire, and count the rotations of the driveshaft required to make one tire rotation - that should take all of 10 minutes then post your results and :beer:
