Has any one made a square drive shaft??????????

I have one. Been holding up great since I made it in 2003. When the front hubs are locked, and its in 4wd, it isn't too bad. Its just very important to phase the U-joints like you would with a normal drive-shaft. Also important to use receiver hitch tubing, and not something else.

But if you ever hit 4 high with the front hubs unlocked, watch out. It will vibrate like mad.

I did it because it was cheap. Total cost out of pocket was $34. Would I do it again? No. When I did mine, a long slip drive-line was $700. Now I can get a long slip yoke from all pro for $150 (see: http://www.allprooffroad.com/pickupdrivetrain/31 ) and make my own. All I do is lop off the end of a drive-shaft in my chop saw, hammer in the long slip, center it up in my home made drive-shaft jig (which cost me $0- very easy to make), use a dial indicator to center it up, weld it up, and have a very close to balanced drveshaft which I can also use on the street.

I have run two square drivelines for the last 3.5 years: one before duals (to accommodate the lift) and one after duals. I did not make them but my friend Kyle did. He has made 20+ square drive lines and has it dialed in pretty good. Cost less than 50 bucks.

I have had no problems with mine and I have been running the second one for 2 some years now. I have run it in 4 Hi up to 60 mph (snow) and there is vibration but its pretty minimal. Kyle is pretty good at getting his square drivelines as "balanced" as a square driveline can be. Going slow you hear a clankity clank from time to time but its not very noticeable. At higher speeds you feel the extra vibration but only 30mph +.

Like others said its important to use receiver hitch tubing. I personally will probably continue to run square drivelines because they are cheap and strong as hell. Most of my friends carry their high dollar round drivelines as spares and run the squares.
 
I made this one for my truck after I lifted it, Read up on missouriman's writeup on square driveshafts. pretty simple! but will vibrate at higher RPM.

thanks, where is the link. I have lost it.
I don't see the three beads of brass ran down each side???


you all should pm, or in the tread thank the person who helped you out or gave you the guts to try it.

I ran a continuous weld down the outer edges of each side,
 
for those who have done it, how has your pinion seal held up? It seems like the vibration from the horribly unbalanced square would be horrible on the pinion.

Mine is alittle over 5 years old. I've been through 3 front diffs in that time. The pinion seals seem to last longer than the ring and pinions. I've had no issues with it leaking.
 
must be how you make them.
the one I made for my wife's truck has very little vib even at 70 mph.
maybe I just lucked out!!!

Is this with the hubs locked or unlocked?

I found with mine, if the hubs were locked, in 4wd, it was pretty stable. But if I unlocked the hubs, I had TONS of vibrations.
 
We had this one made for 100$ and run in the back of our jeep. Took two front driveshafts from 80's chevy 1tons and this what we came back with. Needed to get an adapter u-joint to go to a d300 but that was it.
