Drive shaft questions

Has anyone made their own drive shaft with parts from a tractor supply store? Would these work or would they not handle the hp? I have a sbc 350 with t-19. Any advice on the matter please

Tractor shafts are relatively low speed, but pretty heavy duty. That said if you made it right and found a place to balance it, it should work.

All I've ever personally done is hacked up a junkyard drive-shaft to meet my needs. Unfamiliar with the parts you are referring to from the tractor supply.

The tolerances on the slip joint are too loose on the tractor parts. It would vibrate like mad at highway speeds.

I have three tractors that use PTO equipment on the three point and you can see the driveshafts moving around when it's running. Those shafts only spin at 540RPM.

Ok I found my old drive shaft but it has a good wobble to it. If I were to cut out the bent part and change it out. What would I use to make it. What would be the best material to use

Go to the junkyard and pull a DS with the same size tube as the one you have. Splice in the needed tube to make the repair. It's a little bit of a crap shoot because it's tough to tell the wall thickness or inner diameter of a jy ds and it might differ from what you have, but it's worked for me in the past.

I've done this too....I prefer to replace the entire shaft myself.

A local shop can lengthen or shorten your ds as well. For a price, but around here,to shorten is about 50.00, lengthen varies some. I've paid from 75.00-150.00 for that.

You can get double cardan driveshafts (front of Cherokees and TJs I think?) from junkyards and have them shortened to fit front or rear. These can handle angles better.

If you do decide to go double cardan, then you have to change the t-case output yoke, because it is very different in all aspects. Also you must rotate the rear axle pinion up to point at the t-case yoke. If you don't need double cardan then don't do it. Keep it simple as possible.

Can you elaborate a little on this? Where would I get the yoke from? Im doing a t18 swap and am pretty sure ill need a double cardan shaft as my single is at a pretty steap angle now with the t150

The bolt hole spacing is different and the bolts pass from the transfer case side of the yoke and screw into the CV joint.

The yoke availability depends on which tcase you have. The D300 and 26 spline Dana 20 can use the yoke off the front of an XJ tcase or 79 and older Qtrac fullsize Jeep case. Driveline suppliers also have them.

Ok I have 2 of the dana 20 tcase's one from a j truck and the stock one from my cj5 would either of those be a 26 spline and is there a specific year xj that the front yoke fits my rear? Also do I use the front xj shaft or the rear?

Count your own splines to determine if either is 26 spline.

XJ with NP231 tcase has the right yoke. Surely you can google to find out what years those are.
