The failures you are seeing are usually caused by either the u-joints binding for the slip not extending. You definitely have the setup for either of these potential issues with the Revolver shackes and the square tube shaft.
That shackle in the front is a no no, yes it may be a ramp champ but are you building a wheeler or a flex out toy? I would ditch them.

Ok forgive me here but i'm confusedBuild a 2 piece driveline.

Everyone has known that about you for awhile now....Ok forgive me here but i'm confused![]()

Yep...This is mine http://coloradok5.com/forums/attachment.php?attachmentid=90371&d=1253053253Similar to the rear shaft on a long ass truck. Pillow block. ( As long as i'm talkin about what he's talkin bout.)
Ok that's what i thought but i was thinking all driveshafts are 2 pieces
Just not in the sense you thought i was thinking

Yes there is a carrier bearing on top of the crossmember.That is a pretty sweet set up. Are you running a hanger bearing? or what some people call a carrier bearing? I don't think my front shaft is much longer than your top shaft though.... Could you take some more close ups of yours.. But getting ready to change everything to 1410's to hopefully fix the problem... But would still like to see some of your pics though...
Man, all you folks worried about drive-line angles. There was a swamp buggy that I saw once, more years ago than I care to think about, that had that problem solved.
The front and rear diffs were turned so they faced straight up. There was a shaft that came out of the diff and went up to some kind of a gearbox on the frame.
We're talking about 4 or 5 feet.
Then there was another shaft that came straight out of the transfer case and drove that right angle gearbox.
Talk about easy drive-line angles, I think that one used LoveJoy couplings instead of U-joints since it was a straight shot.
The shafts that went from the right angle gearbox to the diffs had a LOT of slip joint range, but the U-joints did not see much angle.
I once saw a picture of it sitting in water up just under the doors. It was parked next to a BIG boat and folks were getting off the boat and getting into the truck. The boat had plenty of water to navigate in.
It seems to me that the truck could drive in 5 or 6 feet of water and not get any in the cab.
Off-road only of course.
I wish I remembered more about some of the things he did to make it work, no idea what the heck kind of steering setup he had, that kind of thing. But, I think I was about 15 years old, and was WAY more interested in the hot chick in the bikini that was helping show the truck.
J..


Exactly......I wouldnt run them either.He is saying not to run a revolver shackle
