I have swapped out many diferrent rear axels over the years and have for the most part (except on high lifted trucks) always put the pinion on the the same plane as the crank and tail shafts. In other words if they were the same height they would line up but they are not so they don't. Acording to my old drive shaft guy you want a minimum of 3 degrees bend at the Ujionts and if the line is straight, tip the pinion down to get this amount of bend. This would occur sometimes when we lowered a car or truck. It's funny thinking back, he never said what the max was you could bend a Ujoint that I can remember. The bend cancels out viberation and lubes the Ujoint. Tim
