Rear driveshaft up front

[rockhound]

The rear half of a two peice driveshaft, turned around and bolted to the front flange of the transfer case, after adding a crawler box, fits. It is approx. 5 1/2 inches longer than the stock front driveshaft.
The stock front shaft had a CV flange, so I would just need to swap that out for it to work.
Any reason why not. I could spring for a new, shortened, rear shaft now, and wheel. Then get the new lengthened front shaft, whenever.
Has anybody ever done that?

I dont think that will work because it has no slip yoke.
when ur axel droops which with no slip yoke it wont flex any because it has no back and forth movement.
why dont you just cut ur front drive shaft and find some pipe and lengthen it i cut myne in half and used 2 inch sch 40 pipe slid the pipe inside and it fit tight and welded the 2 ends together and bam lengthened drive shaft and dont worry about balanceing it in 4x4 it never goes fast enough too vibrate or hurt anything.
good luck

I used the rear half from the 90 in building the square shaft for my truck.

Thumper, you are right about not going fast enough to worry about vibration.The rear part of my 2 piece rear shaft has a slip yoke at the diff, that I would slip into the front diff. and the split section is mounted to a u-joint in the middle. I could unbolt after the u-joint, and bolt that to the flange at the transfer case.
It seems like it's made to order. Just 3/8" to 1/2 shy of being long enough.
WT, you have a square drive shaft?

Yup you just cant beat the feeling of security that come with a driveline built out of 1/4" steel tubing!  Its all slip so it'll never fall apart due to it running out of slip.  Heres the one from my 81, the one on my 90 is much longer of course.

Ingenius!
