square drivelines

Its all in how you build them.
My shaft is very tight and makes zero noise. The seam helps to cut down on this since it gives another edged to reduce the twisting force.
When you are done making it MAKE SURE that you get all the metal shavings and grinding dust out then use a good marine grease. I have had mine in the air slamming down a few times with zero problems.
I will always run square shafts from now on. Best thing since sliced cheese.

Do you run square front and rear or just front?

Interesting.....

I kinda took the opposite approach.

Mine is actually kinda loose.... makes some racket when you're in 2wd. But I run it dry cuz I think that the grease actually attracts more dirt/grime than it's worth.

.250 wall is beefy. A standard d-shaft tube is nowhere near that thick. In that diameter of square tube, it's pretty well bomb proof. I seriously doubt anyone could twist it.

Leadfoot67 twisted the hell out of his. 2" and 2.5" .25 wall square tubes, just like you describe. That's not to say that a square driveshaft isn't stronger than stock, just not invincible. I was surprised that the u-joint or yoke or even the welds didn't go first, but it just twisted up the tubes instead.

Yep, 2" would be short if I were referring to the length and not the OD...

Now if only the term diameter was normally used in reference to square things...

I was overtired last night and couldn't think of the proper term. Just wanted to get the point across that I wasn't referring to length.

I used to work at a tractor shop and there were lots of old drivelines laying around. some were splined and some were square tube. Has anyone ever thought of useing one of those to make a diveshaft? they're plenty strong and have lots of travel, plus the two halves already fit together right so there is not a lot of play in the shaft.

My next d-shafts are going to be made of splined PTO parts.

Good idea. We do lots of DL stuff here. I may use some old tractor stuff.

I run them front and rear.
Rear is all 1410 joints with a custom long slip 1410 yoke at the t-case end.
