Fatter driveshaft goes where?

[Hawk6815]

I've got two very similar shafts. Does the bigger circumference shaft go front or rear?

you put the smaler diamiter shaft on the front so it misses thr=e oil pan

Ok, so here's my measurements 30.5 front and 29.75 rear. The shafts I've got, the skinnier one is shorter.

The single u-joint mounts to the differential. The double cardan joint (2 u-joints) mounts to the transfer case. It will become obvious when you go to install!!!

Just read your second post. Driveshaft length is what's important.

did i build thoes the look like mine

 

[Hawk6815]

You did, the are very close, I'd say about 3/8" difference but the rear is the longer of the two.

I made the front out of 2" because ov the clearance issues accocated with the oil pan also you get a little bit more angle out of the front

I'm tracking that. I was just puzzled because the front is the longer stretch but the shafts I got, the fatter of the two is the longer one.
