Doesnt that happen with bad axle wrap? Maybe some caltracs or something? Ive also used the u bolt type fastner vs the strap type fasteners your using now. The straps on my 14boltsf would'nt keep the u joint tight.

Is there a stronger u-bolt style pinion yoke for the 9.5" 14 bolt? DSS thinks the same 30 spline 1350 yoke as fits the GM 8.5" (Mark Williams # 39003) will work, but Mark Williams isn't so sure. I don't know how the pinion shaft/bearing sizes compare.

I see you are still using the stock stamped steel control arms and locator. There is a chance you are still getting some axle movement as those components are pretty flimzy compared to the power you are making. I changed the lca and panhard on my respectively low powered Tahoe and noticed a difference, especially when towing. Might be something worth looking into.

I was advised long ago by Inland Empire Driveline that the power I was putting down with the Tahoe back in the day was better served by a steel shaft. We went with a fixed yoke on the Gear Vendors output shaft and a splined steel shaft with solid 1350 joints in between. That configuration eliminates slipyoke binding on the tailshaft and has been bullet-proof through all motor configurations. I went with the same setup on the Suburban.
Honestly, it should be breaking axle shafts or ring gears before breaking the driveline.
