Might want to add info about adding a grease fitting along the length and drilling a small hole in the square tube near the diff to drain water from the tube.
Looks good. Pictures always help.

Good write up. I think it was pretty straight forward and through.

so . . . what's the benefit of a square driveshaft?

A square driveshaft gives you as much slip as you have room. They don't balance very well, so are usually used in the front. People usually use reciever material, cause its off the shelf and doesnt have a standing seam weld. I have seen them in the rear, but only on a trailer queen. The only major downfall is that they don't spin well on a rock, and can cause major damage to xfer case or diff if you do bounce them on a rock.

I would not use them without some good lift, or in a case where you actually need 18" of slip. I have 10" on my tractor spline and have never had an issue.

People do it because it's cheap. $50 compared to $350 for one from a drive shaft company.

People do it because it's cheap.And strong.

10" tractor spline male and 3" of female $45. I am not putting squares down, in fact if I didn't find workable tractor stuff then that is the route I would go.
