I am seeing if my pinion angle calculation is correct, I am going by this link http://www.pirate4x4.com/tech/billavista/PR-shaft/index2.html This is what I have, both set of slopes are in the same direction. Transfer case 3.5 degrees, drive shaft 9 degrees, and pinion is 16 degrees. so going by this statement "If both slopes are in the same direction (up or down), subtract the lesser number from the greater to obtain the operating angle" This gives me 5.5 degrees front and 7 degrees rear. I took my readings off of the yokes as per the article. Am I correct with my assumption that I am at 1.5 degrees total?
