not on a cardan you wont, few degrees and it will shake like Elvis. the pin must be at least close to parallel to the drive shaft. +-1* . Tipping the rear up is the ONLY way to run these. Or it will fail Catastrophically. this can lead to a Tcase failure and other mayhem.
It's been theorized in post 40 based on statements in post 38 that this is a front driveshaft.
It's also worth noting the guy is running a ~2" BB or equivalent, how many times do we see people on here with front driveshaft issues with BBs? Or even rear driveshaft issues with BBs?
If you look closely you'll see grease on the u-joint's trunion, and you'll see some grease splatter on the H yoke.
The most telling part of that picture is the actual fracture itself.
See how the top is a very bright whiteish color, indicative of a fresh break.
If you look lower you can see grease contamination on the same fracture.
To me it's highly unlikely that all the grease shot out and only hit a small part of the fracture. Even if that was the case, how often is the grease in a driveshaft that gray color? The grease on the trunion looks very lightly colored.
From what I'm seeing, it looks like the centering yoke got a stress crack in it, or more likely it had a defect from the manufacturer, and over time it finally let go.
That's my C.S.I. Jeepforum report based on preliminary evidence.
