Square driveshaft's

[optimus]

hey guys. I am trying to find info on making a pair of square driveshafts for my trail-rig. If anyone has any links/ guidance/ pictures please post them up.

Reasons I want a square driveshaft:
1. To get more "slip" (travel before the driveshaft comes apart).

2. It is strong.
3. It is easy to make and fix.
4. It is CHEAP!!!
5. It is EXTREMELY CHEAP!!!!!
6. It is infinitely adjustable.


Cheers. :)

it is also most probably fairly important that I chuck this in:

To balance the shaft I will 1/2 fill the smaller dia shaft with sand and then seal up the shaft so that there is no water ingress and no chance of the setup rusting.

I also think that it is a good idea to put a bicycle inner tube over the slip fiting to stop water and grit getting into it.

I will most likely use 2 1/2" x 1/4" wall tube for the outer and 2" x 3/16 or 1/4" wall for the shorter inner tube.

I will also most probably use tom woods uni's for all uni's in the double cardon and the other end of the shaft if I can get them to fit a Toyota.

There is also this:
When you weld in the CV side of the shaft, make sure you leave enough room for the joint to fully flex. Someone ground the end square and dropped it into the tube and welded it. Unfortunately, they ground too much, so when it dropped in, it dropped in too far so that when the joint moves it hits the tube, thus stopping it. It wasn't TOO bad, but it isn't great either. he don't know yet if it is enough to be a problem on the truck. He is going to have to try to take a dremel and groove the square tube to create more room for the double cardon to move.

Here is my experience with mine. You can't balance it so don't even try. If you want one that is balanced spend the money on a TG kit and do it right. Your wasting your time with the whole lubrication, bicycle tire thing. Just run it it'll be fine. I force some grease between the two tubes on mine occasionally and that's more than most people do that have them.

Yes they are cheap and strong as you stated but there are a few things to be aware of..... if you have your hubs locked and your not in 4wd they make all kinds of racket. Some people claim speeds up to 50mph with them. I have an IFS CV on mine and anything above 30 starts to rattle your teeth. Good luck with whatever you come up with. I love mine but after snow wheeling this year where some speed is required a real front shaft has been budgeted into my wheeling fund....:thumbs:

i have them front and rear on my 4 runner. twisted a round piece of **** so decided to build a square driveline. i can go 70mph it vibrates but i dont drive it very often on the road so i dont care. im getin ready to build 2 more for my land cruiser. i use reciever hitch tubing then another 1 that will slide in snugly. like the other guy said dont worry about grease or water just run it. or run the bigger side towards the t case so no water collects. my buddy has his like that and has no problems.
