I busted my cobbled together u-joint on the '46 a few weeks back, and have been looking for a full replacement, and thought I found one a week ago in what I was told was a '41 thru '46 truck.. it was just the running gear and chassis sitting on the ground, so I had no way to confirm the year, but it was a torque tube setup.
I pulled it apart, and while the joint itself looked different than mine, I thought hey, it looks about right, i'll give it a try.
Turns out on my original part, the tranny side, the do-dad has 10 splines.. but on the side that slides into the driveshaft it has lots more splines, and alot smaller.
The joint I pulled out of the donor vehicle had 10 splines on each side.
Recently, I ran across a fellow in the swap meet section with '46 parts for sale, so I asked him about the joint.. a few days later, he sent me a pic.. that looked just like the joint I pulled from the donor vehicle.. an eMail later, he confirmed that his has 10 splines on both
So my question is.. did they use two different kinds of joints in '46? Or maybe the part I got (and the one this swap meet guy has) are from a 3/4 ton? Did they use torque tube setups in 3/4 tons in '46?
Or maybe somebody did something goofy with MY truck in the past, and it's ME that has the wrong joint?
I wanna get this figured out, because if I end up having to bite the bullet and buy a brand new joint, I don't wanna end up with the wrong thing.
So I guess what i'm asking is, is 10 large splines on the part that connects to the transmission and more than 10 much smaller splines on the part the slides into the driveshaft sound right for a '46 1/2 ton u-joint? What would 10 large splines on both sides of the u-joint be for?
