Pinion angle can be changed on radius rod style suspensions by adjusting their length causing the pinion to rotate up or down.
To find the working angles follow these steps. Place angle finder on bottom of driveshaft and write down the reading. The angle from vertical will be equal to the angle of the centerline of the pinion gear to the horizontal. Place an angle finder on the bearing cap and take note of the reading. Begin by measuring the angle of the driveshaft and writing it down. Find the difference between the two readings and this will be that u joints working angle.
