Axle part numbers

[dmaddox]

hello

I just purchased (a good deal) a set of what I was told were late model FJ40 axles. yes, front is disc, rear has drums, has castle nut on flange and the offset flanges, etc....

However - I was hoping someone could help me identify the year?

Both axles on the 3rd member have:

41111-60011 .....has the Toyota Part number format - however my searches gleaned nothing :-(

thanks for any info!

Castle nuts were done being used to retain companion flanges on pinions prior to 08/69.

hmm, I thought disc axles were not introduced until late 75? I could be mistaken.

Same with fine spline vs. coarse?

Measure the knuckle stud pattern and compare it to the numbers found HERE <---- this is a link

Fine vs. Coarse what, pinions?

Pinions went fine spline in 01/78.

Inner axles/axle side gears in differentials went fine spline in 1968.

Outer axle stub went fine spline in the USA with the disc brake change in 08/75, and is longer than 01/79 outer axle stubs.











Parts are parts bud...anyone could make anything out of a pile of axle parts. Not until you take things apart and verify what you have, will you know for sure.

Cool thanks. I am not showing images so I assume it has to do with the site upgrade.

I'll be digging into them in more detail tomorrow - thanks for the help.

As far as I see, all the 40-series third member p/ns from 1970 through 1984 start with 41110 - your 41111 is close but I couldnt find anything.

EDIT: Just read Poser's reply, maybe the third might be older than '70?? You're not the only one with that p/n tho: https://forum.ih8mud.com/647174-post21.html Also I kept looking up until later years, even 80 series still use the 41110 block for a third. \

For some reason the pictures are not working in Poser's link, which I am attributing to site upgrades?

Anyhow. I pulled the read pumpkin cover off and there was a number (hard to read) on the ring gear.

It was as follows: 9 x 37 078 2 2? 4

Again, hard to read, so numbers may be off.

Regardless. I looked down into the spider gears at the end of the axles and they are fine spline. Which I guess means late model?

Here are some pictures of the axle:

Here are some pictures of the FRONT axle (obviously).

Thanks for any information!!!

9 x 37 = 4.11



The rear axle shafts being fine spline only means that they are 1968 and later. They are later than what would be stock in a 1967 and earlier 40 series.



What are the month/year on the brake hose rings? 07/76?

Sorry, brake hose rings? I know - stupid question, but I am not sure what you are referring to.

Thanks,

Psst!

Older era Toyota brake hoses have a DOT banana date on them. Those rubber rings around the brake hose in your pictures have “DOT and then 00/00” on them.


New Toyota brake hoses have the year/month imprinted into the hose, indicating when the hose was manufactured.


Look at them and post up what you find.

02/76 on the brake line rubber rings. nothing on the rear axle though.

02/76 on the brake line rubber rings. nothing on the rear axle though.

The wheel bearing hub and rotor assembly looks like it is correct for that period, as they were used between 08/75-07/80.


I bet if you measure the steering knuckle stud pattern you will find that it is the 11mm, small bolt pattern used until 12/78.

However, with the above stated it would not surprise me to find out that it is a mix-match of parts to get disc brakes.


On your rear axle assembly, you can only really know an approximate period for it based on the rear axle shaft having a race pressed onto the axle shaft, or the race being part of the rear axle shaft.
