long story short... had Arizona Drivelines build a longspline rockcrawler set of driveshafts. Drilled and tapped np208 tailshaft and used a bolt to eliminate slip yoke. Drove to Moab for Easter Jeep safari. Broke bolt on yoke. took it back and managed to get it repaired for free and get a spare yoke for free. Out last weekend and the C.V. H-yoke shatters. Took it back and they say it probably bottomed out. I am running revolvers and a shackle flip, stockoverloads flipped too. what is happening?
